4/20/2017 Ways to do your Best! Test taking tips Reducing test anxiety Adapted from www.kidshealth.org General Tips 1. Get enough sleep before the test 2. Listen closely to all directions 3. Read through the section you are being tested on 4. Relax 5. Double check your answers FCAT TEST TAKING TIPS Ways to Improve your Testing Strategy Essay Exam Tips Organize your thoughts in a brief outline Look for key word: compare, contrast, describe, and identify Remember to keep your focus and answer only the question Topic Sentence, Definitions of key words, how they relate to each other, and a concluding sentence Multiple Choice Test Tips Think of your own answer before looking at choices Eliminate clearly wrong answers Use your best guess if you get stuck between 2 answers Don’t focus on the amount of questions, take it one question at a time Stick with your 1st guess Relax your mind by taking a deep breath Hold your pencil loosely and not too tight Pace yourself so that you don’t speed through If you use the restroom, remember to not get distracted because the time out of the classroom is not given back to you Think positively you will do great! : ) Read through the formula/reference sheet so that you are familiar with the information Read directions carefully so that all parts of the question are answered Answer the easier questions first so you can focus on the more difficult ones later Do you remember??? How to Reduce Testing Anxiety Tips for the Math Section What types of organisms perform photosynthesis? Why is photosynthesis essential for plants? Cellular Respiration Its how our cells release energy from food! BrainPOP: Cellular Respiration What are the reactants (what goes in)? What are the products (what goes out)? Which plant organelle is the site of photosynthesis? If animals don’t do photosynthesis, how do they get glucose? Which organelle releases energy from food? 1 4/20/2017 Cellular Respiration This process happens in BOTH Why do plants and animals BOTH need to do cellular respiration? Animals need to release energy from food they eat! The process by which cells release from glucose (sugar). PLANT and ANIMAL Plants need to release energy from the food they make! cells! Do you think this process happens in plants, animals or both? There are other molecules involved in cellular respiration…. Which organelle is the main site of respiration? (Hint: they are the same ones involved in photosynthesis) Glucose is the most common sugar found in food! O2 H2O The mitochondria!! C6H12O6 Besides glucose, what else do cells use for cellular respiration? CO2 Two Stages of Cellular Respiration Use your textbooks… page 382! Oxygen energy oxygen Stage 1: Stage 2: In the cytoplasm In the mitochondria How do we get oxygen? Glucose is broken down into smaller molecules Breathing food breathing A small amount of energy is released The smaller molecules react and produce carbon dioxide, water and large amounts of energy. 2 4/20/2017 What are the reactants and products of cellular respiration? Cellular Respiration Equation Compare and Contrast: Cellular Respiration & Photosynthesis This energy is also known as ATP! C6H12O6 + 6O2 glucose + oxygen 6CO2 + 6H2O + energy carbon dioxide + water + Photosynthesis Reactants (what goes in) Reactants energy Products (what comes out) Is matter conserved after this chemical reaction? Products Organelle in which it occurs Type of organism Create a Venn Diagram to compare and contrast Photosynthesis & Cellular Respiration Cellular Respiration light energy, CO2, H2O glucose, O2 chloroplasts producers such as plants and algae glucose, O2 energy, CO2, H2O mitochondria both plants and animals Exit Slip “P”= Photoysnthesis only “C”= Cellular respiration only Description 1. Releases energy from food Cellular Respiration Photosynthesis both 2. Converts sunlight into chemical energy (food) for the organism 3. Performed by autotrophs (plants) only Answers C P P 4. Produces carbon dioxide C 5. Produces glucose and oxygen P 6. Occurs in the chloroplast P 7. Occurs in the mitochondrion C 8. Uses glucose and oxygen C 9. Uses sunlight, water and carbon dioxide P 10. Performed by both autotrophs (plants) and heterotrophs (animals) C Water Cycle The water cycle involves the processes of evaporation, condensation, precipitation, transpiration, percolation and runoff. Percolation BrainPOP: Water Cycle 3 4/20/2017 What are decomposers? Carbon Cycle CO2 Producers take in CO 2 during photosynthesis. photosynthesis. Plants and animals release CO 2 to the atmosphere during cellular respiration. respiration. When fossil fuels are burned , CO22 is released into the atmosphere. Organisms that break down dead plant and animal matter. Ex: bacteria, fungi, earthworms CO2 The process by which carbon moves between organisms and their physical environment. BrainPOP: Carbon Cycle CO2 CO2 CO2 CO2 Consumers take in carbon when they eat plants or other animals. When plants and animals die, decomposers break down their remains, releasing CO 2 into the atmosphere and soil. After millions of years of being buried in the Earth, dead plant and animal matter becomes fossil fuels (oil/coal). Other natural ways carbon is released into the atmosphere… Volcanic eruptions and forest fires Carbon sinks (absorbers) Carbon sources (releasers) Plants Animals Ocean Decomposers Atmosphere Volcanic activity Soil Deforestation Burning fossil fuels How humans affect the carbon cycle… Burning fossil fuels is releasing more carbon into the atmosphere. Deforestation removes trees that absorb carbon and the fire releases carbon dioxide. So, more carbon is being released now than is being absorbed!! Adventures of Carbon Dude Exit Slip (carbon cycle) 1. During the carbon cycle, by which process do producers (plants) obtain carbon from their environment? 2. How do consumers (animals) get the carbon they need? Oxygen Cycle The process by which oxygen is recycled through ecosystems. 3. When organisms die, what other type of organism breaks down their remains to return carbon into the soil and air? 4 4/20/2017 The ocean also plays a BIG role in the carbon and oxygen cycles! O2 O2 O2 O2 O2 O2 O2 Plants produce and release oxygen during photosynthesis Questions 4. Explain how the cycles work together to keep a balance of oxygen and carbon on Earth. O2 Animals take in O 2 from air or water There is 50 times MORE carbon in the ocean than in the atmosphere! Marine plants (such as algae) are responsible for producing HALF the oxygen that we breathe! Nitrogen Cycle The process by which nitrogen is recycled in an ecosystem. “Free” nitrogen falls to the Earth in precipitation What is the source of energy for all cycles in nature? Free nitrogen is converted into a usable form by bacteria on plant roots in a process called nitrogen fixation. Decomposers return nitrogen to the atmosphere and soil through waste and decay. The usable nitrogen can now be absorbed by the plants BrainPOP: Nitrogen Cycle Animals get nitrogen from eating the plants or by eating other animals that ate the plants Cell Structure Organelles and their Functions 5. Describe what must happen to nitrogen gas (“free” nitrogen) before organisms are able to use it. BrainPOP: Cell Structures 5 4/20/2017 Prokaryotic Cell vs. Eukaryotic Cell Parts of a Cell Eukaryotic Prokaryotic • Have a nucleus with DNA • Larger • Do not have a nucleus, DNA is floating around. • Smaller Ex: Plants and Animals Ex: bacteria Cell membrane Cytoplasm Nucleus -nucleus -cytoplasm -cell membrane -vacuole Mitochondria -mitochondria -chloroplast Vacuole -ribosomes Ribosome Endoplasmic Reticulum Golgi body -endoplasmic reticulum(ER) -cell wall Chromosomes Nucleus CELL MEMBRANE “Blueprint” or “Instruction manual” “City Hall” “The Security Guard” are found inside the nucleus Controls all of the cellular activities -chloroplasts controls what goes in and out of the cell holds the cell together carry information that directs the cell’s activities Contains chromosomes with DNA 51 Endoplasmic Reticulum Mitochondria “Power plant” Takes in nutrients, breaks them down Releases energy the cell can use to live and function. “Mighty” Mitochondria “Fedex” Manufactures, packages and transports materials throughout the cell.

Vaculoes “Storage Tanks/Warehouse” • Stores food, water, wastes and other materials. • Vacuoles are BIGGER in plant cells because of the water storage. • They also support the plant cell. 57 Ribosomes “Factories or Construction Sites” Make proteins Can be attached to ER or floating Chloroplast (plant cells only) “Solar power plant” • Contain chlorophyll (green pigment) •Where photosynthesis takes place—they make glucose (sugar that plants use as food)!
