The goal of this lesson is to teach younger learners about plants and how they survive in their environments. This lesson incorporates North Carolina math and science standards and Common Core language skills. By growing plants in a variety of soil types representative of North Carolina soils, students will learn (1) the basic life cycle of a plant and (2) how soils influence plant growth. Through observation and scientific note-taking, students will learn the structures of a plant and their functions. By measuring growth parameters (height, number and length of leaves, number of flowers, size of roots), students will use basic math skills to compare plant growth in each soil type and represent their data graphically. Through research, preparation, and reporting to their class on a food plant of interest, students will gain experience in the language arts. North Carolina Essential Standards Science 1.L.1 Understand characteristics of various environments and behaviors of humans that enable plants and animals to survive. 1.L.1.1 Recognize that plants and animals need air, water, light (plants only), space, food and shelter and that these may be found in their environment. 1.L.1.2 Give examples of how the needs of different plants and animals can be met by their environments in North Carolina or different places throughout the world. 1.L.1.3 Summarize ways that humans protect their environment and/or improve conditions for the growth of the plants and animals that live there(e.g., reuse or recycle products to avoid littering). 3.L.2 Understand how plants survive in their environments. 3.L.2.1 Remember the function of the following structures as it relates to the survival of plants in their environments: Roots – absorb nutrients; Stems – provide support; Leaves – synthesize food; Flowers – attract pollinators and produce seeds for reproduction. 3.L.2.2 Explain how environmental conditions determine how well plants survive and grow. 3.L.2.3 Summarize the distinct stages of the life cycle of seed plants. 3.L.2.4 Explain how the basic properties (texture and capacity to hold water) and components (sand, clay and humus) of soil determine the ability of soil to support the growth and survival of many plants. 5.L.2 Understand the interdependence of plants and animals with their ecosystem. 5.L.2.3 Infer the effects that may result from the interconnected relationship of plants and animals to their ecosystem.

Part I. Growing plants in NC soils Students will be able to: 1) Describe the basic life cycle of a seed plant 2) Illustrate how soil type can influence plant growth 3) Interpret data and determine which of three soil types is best for plant growth Part II. Mimicking damage caused by common pests of NC Cole crops Appropriate Grade Levels Group Size/# of students activities are designed for Setting (e.g. indoors, outdoors, lab, etc.) Approximate Time of Lesson (Break down into 20-50 minute periods) Resources Needed for Students (e.g. scissors, paper, pencils, glue, etc.) Resources Needed for Educators (e.g. blackboard, PowerPoint capabilities, etc.) Students will be able to: 1) Describe what the different parts of a seed plant are for (e.g., seeds, leaves, roots, flowers) 2) Interpret data and compare how damage to different plant parts can influence plant growth 3) Combine what they learned in Parts I and II in a presentation about a favorite fruit or vegetable Elementary School (K-5) Part I. Plants can be grown by individuals, pairs, or small groups of students depending on class size and teacher preference. Part II. Students should work in small groups to mimic insect damage caused by common pests of NC Cole crops. Suggestion: Have students mimic caterpillar damage (hole punch) in class and the teacher mimic wireworm damage (scissors) before class time. Depending on the age of learners and/or teacher preference, all damage could be inflicted by a teacher or by helpers. Indoors Part I: Around 2 weeks (1 day for introduction and seed planting; ~14 days for plants to grow to the flowering stage; 1-2 days for wrap up, including taking plant measurements and calculating and graphing average measures of plant growth). Part II. Around 2 weeks. The teacher should plant Wisconsin Fast Plants® seeds in clear cups with standard potting soil a few days before starting Part II of the lesson (Parts I and II can overlap by a few days to shorten the total amount of time needed to complete both parts of the lesson). The plants will take ~14 days to reach the flowering stage again, at which point the students will take plant measurements and calculate and graph average measures of plant growth as in Part I. Students should start inflicting damage once plants have at least a few leaves (day 5 or 6 after seeds were planted). Part I. Rulers for taking plant measurements Part II. Paper punch, scissors General. Each student should keep a lab notebook (e.g., several sheets of paper stapled together [see Observation page template]) with observations, drawings, data, and conclusions from both parts of the lesson plan. Part I. Clear cups, components of three soil types (potting soil with vermiculite, sand, clay, rocks), three bowls/bags to mix soil in, 1-2 packets of Wisconsin Fast Plants® seeds, watering can, markers to write names on soil cups. Soil type recipes: Mountain: Mix 1 part pebbles/rocks with 3 parts potting soil Piedmont: Mix 3 parts clay with 1 part potting soil Coastal Plain: Mix 3 parts sand with 1 part potting soil Part II. Clear cups, potting soil, 1-2 packets of Wisconsin Fast Plants® seeds, watering can, markers to write names on soil cups. General. Black/white board for collecting data and reinforcing concepts, PowerPoint and a computer connected to a projector to display images from provided slide presentation (if desired). Apps/Websites Needed Not required, but NC Dept of Agriculture has a lot of good resources online. Lesson Activity (step by step description of activity) Overview & Background North Carolina is very diverse both geographically and agriculturally. This lesson incorporates these two factors into a lesson plan to help students learn about the importance of agriculture in NC. Along with age-appropriate science lessons, we incorporate math concepts and English Language Arts skills to provide a wellrounded learning experience for elementary students. Experimentation and observation will center on plants, which provide a lot of the food that we eat, and how they are affected by the environment. This lesson has two main parts: In Part I, students will learn about abiotic (non-living) environmental factors that can impact how a plant grows by exploring how soil type, which varies greatly across NC, influences plant growth. In Part II, students will explore the biotic (living) factors that can impact plant growth by seeing how two very different types of insect pests inflict damage to two different parts of a plant, and how that damage impacts plant growth. Step by Step Activity Part I. Growing plants in NC soils Engage: The lesson should begin with a discussion of food that leads into a discussion of agriculture and, more specifically, agriculture in North Carolina. Begin the lesson by asking students about their favorite fruits and vegetables and make a list on the board. Ask students if they know where these foods come from. Have any of the students grown any of these foods, perhaps in a family garden or on the family farm? If not, have any of the students ever seen any of these foods being grown, perhaps during a visit to a farm or orchard? Have any of the students ever visited a roadside farm stand? The discussion should conclude by reinforcing the idea that all of the fruits and vegetables that we see in the supermarket are grown by farmers somewhere in world, which is why we can buy most fruits and veggies year-round. Next, the discussion should move to agriculture in North Carolina. Have any of the students been to the North Carolina State Fair and learned about some of the many crops grown in NC? [Note: Information about the diversity and value of crops grown in NC can be found in the NASS survey information provided]. Part of the reason that we are able to grow such a wide variety of crops in NC is due to the fact that the state is very diverse geographically - we have both mountains and beaches! NC can be divided into three main regions based on geography - the Blue Ridge Mountains, the Piedmont, and the Coastal Plain. Different types of crops are grown in the three regions of NC because some crops grow better in the Mountains, some grow better in the Piedmont, and some grow better in the Coastal Plain. Why? There are many reasons, but the fact that different types of soil are present in the three regions has a big impact on what types of crops can be grown there. Therefore, the goal of Part I of this lesson is to determine how soil type affects plant growth using NC soils as a model. Explore: Provide each student (or pair or small group of students) with a clear cup with soil from one of the three regions of NC and a clear cup with 2-3 Wisconsin Fast Plants® seeds. Have students write their name(s) on the soil cup and then plant their seeds in the soil cup (placed on top of soil). Students should be responsible for watering and maintaining their plants over the course of the experiment. Hand out a lab notebook to each student and have them make their first entry, including their name, their soil type, and the date that they planted their seeds and any initial observations that they may have. Students should observe their plant every day and keep a daily log of observations and drawings in their lab notebook. Students should keep track of when their seeds sprout and when leaves and flowers appear [Note: Plants can be thinned to one per container if desired]. Students should also make observations regarding the growth of leaves and any other plant parts that might develop over the course of the experiment. After approximately 14 days, or once most plants have flowers, have students harvest their plants and collect the following data (see Data collection template): 1) Overall height of plant 2) # leaves 3) Length of each leaf (up to 10 leaves) 4) # flowers 5) Length of three longest roots 6) Plant weight (if scale is available) During a subsequent class period, collect data from each group on the board and calculate (or have the students calculate) average values for each type of measurement made on plants grown in Mountain, Piedmont, and Coastal Plains soil types. [Note: Students can practice how to calculate averages by calculating the average length of leaves and the average length of the three longest roots on their plants.] Have students graph and then compare how plants grown in the three soil types differed according to the measured characteristics. During a class discussion, determine in which soil type the plants grew the largest. Were different parts of the plant larger/smaller when grown in different soil types? How did soil type affect plant growth overall? Which type of soil is the "best" for growing this particular type of plant? Based on the class data, in which region of NC would the students choose to grow this particular type of plant? What aspects of the soil in each region might have affected plant growth? Explain: Periodically over the course of the 14-day growth period, ask students to share what they have observed so far about their plants. Are there any obvious differences between plants being grown in the three soil types? Elaborate: After students have chosen which region in NC they would grow this particular type of plant in, extend the class discussion to factors other than soil type that might affect how plants grow in the three regions in NC. Have students brainstorm ideas and create a list on the board. Abiotic (non-living) factors might include weather, temperature, elevation, etc. Biotic (living) factors might include pests, beneficial organisms such as pollinators, etc. Use this part of the discussion to bridge to Part II of the lesson. Part II. Mimicking damage caused by common pests of NC Cole crops Engage: Ask students to describe what the different parts of a seed plant are for (e.g., seeds, leaves, roots, flowers). The teacher can link this discussion back to Part I of the lesson if different parts of the plants were larger/smaller on average when they were grown in different NC soil types. During or after the discussion, have each student label the parts of a plant and explain the role that each part plays in the growth and development of the plant. [Note: This can be done as a class activity but each student should create their own information page to go in their lab notebook (see Plant parts template)]. At this point, remind students of the list of factors other than soil type that they thought might affect plant growth during the wrap-up discussion for Part I. Just like each part of a seed plant serves an important function and is essential for its survival, remind students that other organisms also have to meet their own needs in order to survive. To this end, there are a number of organisms that depend on seed plants for their survival - some consume plants for food (pests and/or livestock), while others visit plants to collect resources that they need to survive (like pollinators). Wisconsin Fast Plants® are members of the crucifer family of plants and are closely related to cabbage, turnips, broccoli, and other cruciferous vegetables. A number of pests that inflict different types of damage attack cruciferous vegetable crops (aka, Cole crops) in NC and surrounding states (see Extension handout). Therefore, the goal of Part II of this lesson is to determine how one type of biotic factor, pest damage, affects plant growth and development. Explore: Start to grow Wisconsin Fast Plants® a few days before starting Part II of the lesson. Seeds can be grown in regular potting soil in clear cups as before. In this activity, students - with the teacher's help - will mimic the damage caused by two different kinds of pests that commonly attack Cole crops and measure the effects of different types of damage on plant growth. Pests include wireworms, which live underground and attack plant roots, and caterpillars that feed on above-ground plant material (see PowerPoint slides for more information). The experiment should be run with three treatments, including 1) a "no damage" control, 2) wireworm damage, and 3) caterpillar damage, but can include an optional fourth treatment consisting of 4) wireworm and caterpillar damage together. It is best to have roughly equal numbers of plants assigned to each treatment, so divide students into small groups based on the number of plants that will receive a treatment involving caterpillar damage. [Note: If the teacher has access to live aphids, they can be placed on plants as another optional fourth treatment. Aphids insert their mouthparts into plants and suck up plant juices, inflicting a different type of damage than caterpillars, which chew up leaf material. Alternatively, a video of aphids sucking on plants could be watched during the discussion part of the lesson to illustrate the damage caused by a different type of pest]. Each day, starting after plants have grown for a few days and have at least a few leaves, inflict damage to plants assigned to each treatment as follows: 1) Control - do nothing 2) Wireworms - use scissors to cut down into the soil to damage the roots [Note: This is a job for the teacher only - one cut per day should be enough]. 3) Caterpillars - have each student punch one hole in a leaf on their group's plant using a handheld hold punch Optional treatments: 4) Wireworm/caterpillar - combine techniques described above 4) Aphids - place a few aphids on each plant and let them do their thing After approximately 14 days, or once most plants have flowers, have students harvest their plants and collect the same data that they collected in Part I of this lesson (see Data collection template): 1) Overall height of plant 2) # leaves 3) Length of each leaf (up to 10 leaves) 4) # flowers 5) Length of three longest roots 6) Plant weight (if scale is available) Again, collect data from each group on the board and calculate (or have the students calculate) average values for each type of measurement made on plants that received each type of damage. Have students graph and then compare how plants damaged by each type of pest differed according to the measured characteristics. Explain: Ask students how their observations of the damaged plants were different from those of the “normal” undamaged plants. Were there differences in the number of leaves? Were the plants the same height? Was there a difference in the number of flowers produced? Did plants die? Ask the students to explain these differences based on what they’ve learned about how the different parts of a plant help it grow and survive. We recommend that the teacher ask these questions during a class discussion, however, students could explain this information in their notebooks as part of a written assessment. Elaborate: It is important for students to reflect on and then integrate the material covered in Parts I and II of this lesson. To assist in this process, have students pick a fruit or vegetable (their favorite) and research what it needs to grow. Can it be grown in NC? In which part of the state (Mountains, Piedmont, or Coastal Plain) is it grown? Are there any pests that attack it? Have students add this information to their lab notebook and prepare a short presentation to give to the class about growing their favorite fruit or veggie. Reflection/Assessment Part I. Students will make daily observations and drawings in their lab notebook and collect plant growth data at the conclusion of the experiment; notebooks should include numerical and graphical summaries of the data collected. Before turning in their lab notebook, have students reflect on the experiment and what they learned. Have them write down (at least) three things that they learned and one thing that they would do differently if they had to repeat the experiment again. Take some time to evaluate and comment on each student's lab notebook before moving on to Part II. Part II. Students will again make daily observations and drawings in their lab notebook and collect plant growth data at the conclusion of the experiment; notebooks should include numerical and graphical summaries of the data collected and a reflection on what they learned during Part II of the lesson and what they would do differently next time. Students will also complete a short presentation on growing their favorite fruit or veggie. Final Product/Assessment (e.g. quiz, blog, presentation, essay, etc.) Each student will turn in a lab notebook with observations/drawings for Parts I and II of the lesson and will give a short presentation about their favorite fruit or veggie.
