Standard 1: Analysis, Inquiry, and Design Students will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions. Scientific Inquiry: Key Idea 1- The central purpose of scientific inquiry is to develop explanations of natural phenomena in a continuing, creative process. 1. S1.1 Students will ask "why" questions in attempts to seek greater understanding concerning objects and events they have observed and heard about. 2. S1.1a Students will observe and discuss objects and events and record observations 3. S1.1b Students will articulate appropriate questions based on observations 4. S1.2 Students will question the explanations they hear from others and read about, seeking clarification and comparing them with their own observations and understandings. 5. S1.2a Students will identify similarities and differences between explanations received from others or in print and personal observations or understandings 6. S1.3 Students will develop relationships among observations to construct descriptions of objects and events and to form their own tentative explanations of what they have observed. 7. S1.3a Students will clearly express a tentative explanation or description which can be tested Key Idea 2- Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity. Zucconi 2 1. S2.1 Students will develop written plans for exploring phenomena or for evaluating explanations guided by questions or proposed explanations they have helped formulate. 2. S2.1a Students will indicate materials to be used and steps to follow to conduct the investigation and describe how data will be recorded (journal, dates and times, etc.) 3. S2.2 Students will share their research plans with others and revise them based on their suggestions. 4. S2.2a Students will explain the steps of a plan to others, actively listening to their suggestions for possible modification of the plan, seeking clarification and understanding of the suggestions and modifying the plan where appropriate 5. S2.3 Students will carry out their plans for exploring phenomena through direct observation and through the use of simple instruments that permit measurement of quantities, such as length, mass, volume, temperature, and time. 6. S2.3a Students will use appropriate "inquiry and process skills" to collect Key Idea 3- The observations made while testing proposed explanations, when analyzed using conventional and invented methods, provide new insights into phenomena. 1. S3.1 Students will organize observations and measurements of objects and events through classification and the preparation of simple charts and tables. 2. S3.1a Students will accurately transfer data from a science journal or notes to appropriate graphic organizer 3. S3.2 Students will interpret organized observations and measurements, recognizing simple patterns, sequences, and relationships. 4. S3.2a Students will state, orally and in writing, any inferences or generalizations indicated by the data collected 5. S3.3 Students will share their findings with others and actively seek their interpretations and ideas. 6. S3.3a Students will explain their findings to others, and actively listen to suggestions for possible interpretations and ideas Zucconi 3 7. S3.4 Students will adjust their explanations and understandings of objects and events based on their findings and new ideas. 8. S3.4a Students will state, orally and in writing, any inferences or generalizations indicated by the data, with appropriate modifications of their original prediction/explanation 9. S3.4b Students will state, orally and in writing, any new questions that arise from their investigation Standard 6: Interconnectedness: Common Themes Students will understand the relationships and common themes that connect mathematics, science, and technology and apply the themes to these and other areas of learning. Systems Thinking: - Through systems thinking, people can recognize the commonalities that exist among all systems and how parts of a system interrelate and combine to perform specific functions. 1. Students will observe and describe interactions among components of simple systems 2. Students will identify common things that can be considered to be systems (e.g., a plant, a transportation system, human beings) Models: - Models are simplified representations of objects, structures, or systems, used in analysis, explanation, or design. 1. Students will analyze, construct, and operate models in order to discover attributes of the real thing 2. Students will discover that a model of something is different from the real thing but can be used to study the real thing 3. Students will use different types of models, such as graphs, sketches, diagrams, and maps, to represent various aspects of the real world Zucconi 4 Lesson 1(All Grades) Graphic Organizer (Part 1) ‘Know’ ‘Want to Know’ What I think I know about plans… What I would like to know about plants… Zucconi 5 Trees, bushes, flowers, What are all parts of a plant vegetables, grasses They have roots called? Planted in soil Store food What jobs to plants have in the environment? Why are most plants green? Some pollinate Some have stems Zucconi 6 Lesson 2(Grade K-4) What do you know about the parts of a typical plant? A. Hand draw and label all parts of a typical plant. B. Complete the chart below: Plant Part Looks like… What is its job? Makes seeds for the plant petal Attracts insects to pollinate Supports the flower Zucconi 7 stem Provides nourishments, food and water Makes food to feed the plant leaf Provides water to the plant root Holds plant in place Brings minerals up from the ground *Accommodations: For this lesson, I would have the plant figure already drawn out. I could also have the words listed in a word bank. For example, a child with ADHD, would spend most of this lesson drawing out the plant and leave little or no time for naming the plants. For the chart, I could make it, where the words were on one side and the jobs on the other and the students would need to draw a line to connect the word with its correct job. I feel this would save time and lessen the anxiety/frustration a child with a disability or difficulty might have. Instead of having the students, write the plant part, they could draw it. Lesson 3(Grade K-4) How Do I investigate plant cycles? Journey to the Center of a Seed Objective: To discover what is inside a seed; to predict how seeds will change after sprouting and to observe the sprouting (germination process). Zucconi 8 Procedure: 1. For this activity, use either pinto beans, kidney beans or lima beans. 2. Place about 4 beans on a moist (not wet) sponge and over the beans with another moist (not wet) sponge. 3. Keep sponges moist. 4. This activity will take about seven days to begin showing results. Question: What do you predict will happen to the seeds while they are soaking? Prediction: I predict that my seeds will start to grow and things will start to sprout after a few days. Experiment: I used 4 lima beans. I placed the 4 beans onto a moist sponge and covered them with another sponge that was also moist. I kept the sponges moist for 14 days. After the eight days, I began to make observations. Observations: Days 1-5: No changes have been made since I made the sponges moist and placed the seeds in between the two sponges. Days 6- 11: The seeds have begun to wrinkle up. Then two seeds began to crack. I moistened the sponges a few times during the five days. A part of one of the outer layer has been peeled off. The outer layer is white and the inner is a tan color. Days 12-14: I pulled the seed coats off of the lima beans during Day 12. The closer I looked, the more I noticed there were things growing on the seed. It looks like there are two small things that could eventually be leaves. There is a longer, thin piece coming out of the same area as the leaves. I will assume this is the embryo to continued growing and will turn into a bean plant. Reflections: How did your seeds change while they were soaking between the moist sponges? After about six days, the coats on the seeds began to wrinkle up. Two of the seeds started to crack. After the tenth days, two other seeds began to split apart Zucconi 9 Did this match your prediction? This did not match my prediction. I thought my seeds would begin to sprout something since they were surrounded by water. Instead, the seeds just wrinkled and cracked. What do you think was happening inside the seeds? I did not think anything was happening inside my seeds, since nothing sprouted from them. After I pilled off the coats of the seeds, I able to see a few things which made me think things were actually changing within the seeds. I could see something that looked like the beginning of a root. Pull off the outer coat (called seed coat) then pull the coatless seeds in half with your fingernails. Draw what you see. Questions: How does what you see inside the seed compare to your original prediction? The seed coat protects the seed from damage, holds its parts together and probably protects it from drying out completely. None of this matched my prediction. Does any part of the inside of the seed look like a familiar plant part? Which part? The seed has two halves. Attached to one, looks like a baby plant or an embryo. There is a root and two tiny leaves along with a vein. Do you think a seed is alive? Why or why not? Zucconi 10 I do believe that a seed is alive. I think that the seeds are waiting for certain conditions to start growing. Most seeds need things like water and certain temperatures to begin to grow. What do you predict will happen to the seeds during the week? I predict that the seed will continue to grow and the root will get longer and the leaves will get larger. At the end of the week, how did different parts of the seeds change? At the end of the first week, nothing changed except the seeds outer coat began wrinkling. Towards the end of the second week, I noticed a baby plant was in the seed and the seed began to sprout. What happened first, next? The embryo inside of the seed began to grow. Then it developed roots, a stem and eventually then leaves. Continue until you have a fully grown bean plant. Measure the plant growth in centimeters. My seed did not grow into a full plant. The foot began to grow and leaves sprouted, but then everything began to shrivel up and become dry. No matter how much I watered the sponges, it just never continued to grow. Pictures: Zucconi 11 *Accommodations: For this lesson, I would the student set up the experiment in class, if it was a take home experiment, so I could be sure, right from the start, they would beginning correctly. I pre-label all the cups that the seeds needs to go in. I could post visuals, charts and models for concept reinforcement and assurance, within my classroom. I would provide a timeline to assist the student to remain on target and to avoid procrastination. Zucconi 12 Zucconi 13 Lesson 4(Grade K-4) Yo Seeds! Wake up! Objective: To understand that certain factors affect seeds sprouting. Question: Does changing the environment on which seeds are in, have an affect on their growth? Questions: Would seeds sprout on a dry vs. moist paper towel? How could you prove this? Seeds would not sprout on a dry paper towel because seeds need water in order to grow. I could prove this with doing an experiment. I could set up 3 seeds on a dry paper towel and 3 seeds on a moist paper Zucconi 14 towel and leave them on a window sill and observe for five days. What about warm moist paper towels vs. seeds placed in a cool, dark temperature? How could you prove this? I believe that seeds put on a warm moist paper towel would still grow more and have more success than seeds placed in a cool place with dark temperature. Seeds need water in order to grow. Without water, the seeds will not be able to grow and sprout. The warm, moist paper towels acts like the sun and the soil. When seeds are placed in the soil, they need to sun. If the seeds are warm, that the will help to grow. The dark and cool temperature will not make the seeds grow. In order to prove this, I would place 3 seeds on a warm, moist paper towel and 3 seeds in a cool, dark temperature. I would observe them for a week and make observations. Write up an investigation to support your proof. Question- Would seeds sprout on a dry vs. moist paper towel? Predict- I predict seeds will only show signs of growth on a moist paper. Observation on Moist Paper TowelDay 1: No change. Seeds are sitting on the paper towel. Day 2: Still no change with the seeds. Day 3: Still no change with the seeds. Day 4: Two of the seeds have sprouted on the paper towel. Day 5: Two seeds continue to grow. The one seed is not growing. I think it was submerged in some water from the beginning and failed to germinate. Zucconi 15 Observation on Dry Paper TowelDay 1: No change. Seeds are seat on the paper towel. Day 2: Still no change with the seeds. Day 3: Still no change with the seeds. Day 4: Still no change with the three seeds. Day 5: The seeds look exactly the same as they did on Day 1. --------------------------------------------------------------------------------------------------------------------------Question- What about warm moist paper towels vs. seeds placed in a cool, dark temperature? Predict- I predict seeds will only show signs of growth on warm, moist papers. Observation in Warm, MoistDay 1: Placed the seeds on my desk, which is right next to the heater. The sun also reaches through the window in this area. I placed seeds on a moist paper towel. Day 2: Seeds look the same as Day 1. Day 3: Seeds look the same as Day 1 and 2. Day 4: Today, one seed has begun to sprout. This seed is the one closet to where the sunlight reaches. Zucconi 16 Day 5: Two seeds altogether have sprouted. The last seed has not made any changes. Observation in Cool, DarkDay 1: Placed the seeds on a dry paper towel and put them in the refrigerator. When the door is closed on the refrigerator, the light turns off. Day 2: There is no change on any of the seeds. Day 3: There is no change on any of the seeds. Day 4: There is no change on any of the seeds. Day 5: There is no change on any of the seeds. Draw conclusions at the end of each of the activities. Within five days, most of the seeds placed on the moist paper towel, have sprouted, but not the seeds on the dry paper towel. If seeds on the moist paper towel were submerged in water, seeds could fail to germinate because they are too wet. Seed sprouting is generally improved with moderate warmth and inhibited with cool temperatures, such as the refrigerator. Zucconi 17 The seeds only grew in moist environments. In the dry environments, the seeds did not change at all. When the seeds were put in the fridge, they did not show signs of growth. I conclude, that seeds which are placed in extremes of heat or extremes of cold, will not grow. When there is a drought, placed seem to dry out and sometimes die. When there is a heat wave, plants also seem to dry out and die. Experimentation set up: 1. Place 3 seeds on a dry paper towel. 2. Place 3 seeds of the same plant on a moist paper towel. 3. Place 3 seeds of the same plant on a moist, warm paper towel. 4. Place 3 seeds of the same plant on a paper towel and put them in the refrigerator. 5. Check on each once a day for one week and record all observations. 6. Draw what you see for each time you observe. 7. After one week, decide how climate can affect the growth of plant seeds. 8. Combine results on a bar. Number of Sprouted Seeds How many seeds will wake up?! 2.5 2 1.5 Series1 1 Series2 0.5 0 Moist Dry Warm Cool Environment *Accommodations: Since this lesson has several steps, having the student perform different experiments, I would break the assignments into segments of shorter tasks, so they are not placed in front of the student all at once. I would give the children a pre-made chart for their observations because then they would not have to waste time on worrying or having to make a chart to record whatever they notice during each experiment. Zucconi 18 Lesson 5(Grade K-4) Root Loops Objective: To understand that plants respond to gravity by attempting to change the direction of root and stem growth. Use radish seeds for this activity. Procedure: 1. Set up three plastic containers stuffed with moist paper towels. Make sure the towels stay moist. 2. Place radish seeds between the cup and the paper towels. 3. Turn one container on its side. Turn one container upside down. Leave on container upright. 4. All growth to continue for several days in order to make a full observation. Prediction: I predict that al the roots will grow downward because of gravity. Day 1 Glass 1 Glass 2 Glass 3 On its’ side Upside down Upright - no change - no change - no change - no change - no change - no change Zucconi 19 Day 2 Day 3 Day 4 - 3 seeds grew - 2 seeds grew larger larger - no leaves - no leaves - 3 seeds continued - 2 seeds continued to grow to grow - no change - no change - the stem got longer - the stem got longer - no leaves - no leaves - all seeds have - 2 seeds have sprouted sprouted - a white root is - the roots growing growing from each downwards Day 5 Day 6 - no change - all three roots have - one seed has - 1 seed has now grown into the sprouted leaves at sprouted a root paper towel the top - it’s white - the roots are all - the root is growing - there are no leaves growing sideways into the paper towel, downward Day 7 - each seed that has - 2 seeds have fully -2 seeds have sprouted has sprouted sprouted increased in size - they each have - 1 seed has a stem - the stem is longer leaves at the top of with leaves - the root continues the stem - the roots are just Zucconi 20 to grow down staying at the bottom of the cup, while the stem is going up Day 8 - a third seed has - the roots have - 1 stem has pushed sprouted continued to grow aside the paper towel - the stems are downwards through and grew between trying to push there the paper towel the towel and the way out through the cup paper towel - the stem is growing straight up Conclusions: Gravity does affect the growth of plants. When plants grow, the stem and leaves grow upward, while the roots grow downward. The direction that a plant grows has nothing to do with the way that you plant a seed. Stems always find their way up and roots always find their way down. This can be illustrated by looking at the pictures taken from each cup over the eight days. Zucconi 21 Photos: This picture shows the three glasses in their positions at the start of the experiment. Glass #1: on the side, Glass #2: upside down, Glass #3: upright. These three pictures are all from Glass #1. The first picture on the left was taken on Day 4 because there were three seeds that grew. You can see the brown which was the seed, leaves are starting to form, but no stem. The picture below that shows the white portion of the root. It is starting to grow down. The last picture shows the stem with leaves, trying to grow upwards. It grew around from the back of the paper towel. Zucconi 22 Zucconi 23 These three pictures are from Glass #3. The picture below this, show two seeds that have grown white roots. The second picture shows another seed that has sprouted from Day 7. It has a stem with a leaf and a root. The last picture shows two seeds that have grown, have stems and leaves. It is trying to grow the paper towel, but being pushed down by it. Zucconi 24 *Accommodations: I would give the children a pre-made chart for their observations because then they would not have to waste time on worrying or having to make a chart to record whatever they notice during each experiment. If this experiment, was to be brought home, I would send a letter to the parent explaining about the lesson and if they could keep in mind that their child should be making observations each day. After each day, the parent could sign the paper and bring it in to me to show that they wrote down something or have the parent email/call me. Zucconi 25 Lesson 6(Grade K-4) What a Sy-Stem! Question: How does water move through a plant? Objective: To illustrate how plants absorb and circulate water. Procedure: 1. Fill two cups with water. Zucconi 26 2. Dissolve one color of food coloring into one cup and a different color of food coloring into the other. 3. Take a stalk of celery that has leaves on it and cut off a small piece from the bottom end. 4. Take the scissor and split the celery talk into two halves. 5. Place each half of the stalk into each cup Prediction: I predict the left side of the celery’s veins will turn green white the right side will turn black. Hypothesis: If I put a stalk of celery in a cup of food coloring, then the veins will suck up the color from the food coloring. Experiment: I filled two cups with water. I put dark green food coloring in cup A and black food coloring in cup B. Then I cut off the bottom of the celery and split it up the middle with a scissor half way. I put the left end of the celery in cup A and the right end in cup B. I leaned the celery stalk up against the wall. I had the celery for 3 days in the cups. Observations: Zucconi 27 Day 1- The coloring rose up three inches on both sides Day 2- The coloring rose up to the top of celery, even into the leaves. The leaves have somewhat changed color. The left side has hints of dark green, and the right side has hints of black. Conclusions: Water was sucked up by the plant, which traveled up the stalk into the leaves. The tiny tubes or capillaries allowed the water to move throughout the plant. I think this would be an example of capillary action. Drawings/Pictures: Zucconi 28 These pictures are taken from beginning to end of the celery lesson. The above picture shows the celery in two cups of food coloring: green on the left and black on the right. The second picture shows the coloring being taken up the stalk. The third picture shows the coloring moving over half way up the stalk. The last picture shows how the coloring reached the leaves. The leaves are now filled in with darker green. If you look closely at the long leaf in the center, some of the veins are now black. Science in Personal and Social Perspectives If you wanted to give someone a bouquet of carnations to celebrate the Fourth of July and could find only white ones, what can you do to those to get red and blue ones too? Do you think the same thing is done by florists? I would add coloring to the white flowers. The same thing that happened to the celery would happen. The petals of the carnations would turn red and blue from the food coloring. I do think that florists could use Zucconi 29 this method. With all the colors from food coloring, they could create a more diverse group of flowers to sell. You can mix colors, resulting in many different colors for the flowers. Science as Inquiry What force is pulling the colored solution up the stem of the celery in this activity? I believe the force pulling up the color is transpiration. It moves the water to the parts of the celery. What if the celery were placed in clear water? Would the liquid still be drawn up the stalk? How could you tell? If celery was placed in clear water, I do believe the liquid would still be drawn up the stalk. Could a plant live without a stem? Why or why not? A plant could not live without a stem because the stem supports the celery. The stem also provides nourishments, such as food and water. Without food and water, the plant will not be able to survive. Evaluation As a teacher, how would you assess what your students have learned by doing this activity? As a teacher, I would assess my students by having them write down their conclusions. After writing, I would encourage a class discussion on what they wrote down. I would also give them a worksheet which would be in the form of a letter to someone they knew. In the letter they would tell the person about the experiment and what they learned from it. I would also like to have the students set up the carnation experiment to reinforce what occurred in the celery experiment. *Accommodations: This lesson, I would do in front of the class as a whole. I would place the students with disabilities the closet to me for several reasons: 1. Make sure I could see if they get distracted 2. I could ask them to be a helper during the experiment to get them involved If the student no difficulty writing, I could have them become the class recorder. During our class discussion about what observations/changes have taken place, they could be the one to write them. If I decide not to have a class recorder, I could give them a worksheet with a pre made chart to organize their thoughts on where their observations could be placed. Zucconi 30 Lesson 7(Grade K-4) Plants as Food Makers Puzzled by Photosynthesis Directions: From the list below, write the correct words on each puzzle piece. Zucconi 31 Procedure: Using the puzzle above, and prior knowledge, in your own words, explain what is photosynthesis? The word ‘photo’ means light and ‘synthesis’ means putting together. The word photosynthesis means putting together with light. Plants contain chlorophyll and plants take in water and nutrients from the soil through tiny hairs on the roots. The water and nutrients are transported through the root hairs to the roots and then are drawn up the stem through tubes. I remember learning in school that there are two different kinds of tubes: phloem and xylem. Xylem tubes carry the needed water and nutrients up the stem to the leaves where photosynthesis takes place. Phloem tubes carry sugars down from the leaves. Green plants are the only plants that produce oxygen and make food. This takes place in chloroplasts, which have chlorophyll in them. Chlorophyll absorbs the sunlight. From sunlight, green plants combine carbon dioxide and water to make sugar and oxygen. Green plants use sugar to make starch, fats, and proteins. There are tiny pores called stomota. Oxygen and carbon dioxide enter and leave through the stomata. *Accommodations: I think the puzzle piece is a great activity. It has an image and the words listed already. I would have the class work in partners to answer the question. The students would be able to formulate an idea together and work as a team. I would give all students options on how to answer the question to demonstrate their learning: written response, drawing, acting it out etc. Zucconi 32 Zucconi 33 Lesson 8(Grade K-4) Flowers Up Close Plant Part Function of this part? Receptacle Sepal The point at which the floral parts attach to the tip of the stem bearing the flower. The receptacle is often somewhat enlarged. Make up the outer ring of floral parts, Often green in color, though some flowers have brightly Zucconi 34 colored, petal-like sepals. Form the next circle of flower parts, just inward from the sepals. If a blossom is showy, chances are it's the petals you notice. Petal Petals may be separate, or united in a tubular, cupped, or belllike shape. Attract pollinators. Positioned inward from the petals, contain the male reproductive elements. A typical stamen consists of a slender Stamen stalk, the filament, topped by an anther, which is usually yellow in color. The anther contains grains of pollen, the male element needed to fertilize the flower. Pistil Found in the flower's center, bear the female reproductive parts. Each pistil typically consists of an ovary with a stalklike tube rising from it. The stalklike tube, called the style, is topped by a stigma, which receives the pollen. The ovary contains one or more ovules; following pollination and fertilization these develop into the plant's seeds. *Accommodations: For this lesson, I would use the same accommodations as Lesson 2. I would have the flower figure already drawn out. I could also have the words listed in a word bank. For example, a child with ADHD, would spend most of this lesson drawing out the plant and leave little or no time for naming the plants. For the chart, I could make it, where the words were on one side and the jobs on the other and the students would need to draw a line to connect the word with its correct job. I feel this would save time and lessen the anxiety/frustration a child with a disability or difficulty might have. I could enlarge the words, simplify the text or highlight, if the student needed an alternative way to receive information. Zucconi 35 Zucconi 36 Self Assessment Closure Assessment/Evaluation What have I learned by completing this journal based on growth and development of plants? I have learned numerous things throughout completing this journal. Plants are living things. Plants also have several different parts. In a typical plant there are four parts: petal, stem, leaf and roots. Each of these parts has a responsibility to do in order to make the plant grow. Inside a seed of a plant, there are also things that grow. In a flower, there a several parts that all need to function to ensure the growth and success of the flower. Weather and climate have an affect on plants as well. Plants need certain things to grow. Two important factors are sunlight and water. Usually seeds in a warm, moist area will successfully grow. Seeds placed in a cold, dark area will most likely not grow. I learned about roots and how gravity affects the way they grow. Gravity does affect the growth of plants. When plants grow, the stem and leaves grow upward, while the roots grow downward. The direction that a plant grows has nothing to do with the way that you plant a seed. A plant takes in moisture through it’s’ roots. In the lesson called “What a Sy-Stem!”, I learned this by looking at the food coloring in the celery. Just as people have veins to make their blood flow though their bodies, plants have veins that water flows through too. The plants suck up the water from the dirt and the water flows through the plant. The tips of the leaves of the celery plant turned the same color as the food coloring. Zucconi 37 The word photosynthesis means putting together with light. Xylem tubes carry water and nutrients up to the plant’s stem to reach the leaves. Phloem tubes take the sugars down from the leaves. The plants can take the trapped energy and can turn carbon dioxide into a variety of sugars and oxygen. Annotated Bibliography www.nysatl.nysed.gov/standards.html This site is where I found all of the New York State Standards for this journal. http://www.myschoolhouse.com/courses/O/1/124.asp This is a website which had an illustration of a flower. It also had a description of the parts of a flower. There was a test at the end, to make sure you understand the information that was read above. http://andromeda.cavehill.uwi.edu/flower_structure_and_function.htm This site where I found the picture of the flower to label its’ parts.
