Strand 8.3 Ecology Starters
Living things use energy from their environment to rearrange matter to sustain life. Photosynthetic organisms are able to transfer light energy to chemical energy. Consumers can break down complex food molecules to utilize the stored energy and use the particles to form new, life-sustaining molecules. Ecosystems are examples of how energy can flow while matter cycles through the living and nonliving components of systems.

8.3.1 |
I can plan and conduct an investigation and use the evidence to construct an explanation of how photosynthetic organisms use energy to transform matter.

4. Growing Plants
Tuesday, 20 March 2018 Label your coversheet: Ecology. On the front of your coversheet, draw a model of the system that allows a plant to grow. Watch the videos to the top right once. As you do, record at least 4 observations in a T chart. Focus on using the words: matter and energy. Watch the video again. As you do this time, write down 3 scientific (testable) questions about plant growth. How does matter cycle in the system? How does energy flow through the system? How much energy is there in different parts of the system? Where does a tree get matter to grow taller? Where does a tree get the energy it needs to be able to grow? Watch the video to the bottom right. |

5. How does your Garden Grow?
6. Bill Nye: Plants Wednesday, 21 March 2018 Read the "How does your Garden Grow?" article. Highlight important parts. Watch this Bill Nye: Plants video and fill in the worksheet. Amazing TED talk about Plants that don't need much water. |

Photosynthesis Notes
22/23 March 2018 What exactly happens during photosynthesis? Go through this interactive (or this printable version) and take notes on the steps of photosynthesis. Make sure that you have the equation for photosynthesis written down somewhere on your paper. From what you write down, you should be able to answer the following questions: 1. What two molecules are needed for photosynthesis? 2. What does the plant make during photosynthesis? 3. Give evidence that matter is rearranged. 4. Why is photosynthesis important for plants? |

7. Effects of Additives on Seed Germination and Growth
22/23 March 2018, 26 March 2018, 27 March 2018 and finish on 29/30 March 2018 Today in class we also began an experiment. If you were absent, you will need to complete How Does Your Garden Grow instead. How do you think the amount of light a plant receives affects the amount of photosynthesis it can do? Use the following simulation to explore this question. Photosynthesis Simulation Quizizz about Photosynthesis |
|
8.3.2 |
I can develop a model to describe how food is changed through chemical reactions to form new molecules that support growth and/or release energy as matter cycles through an organism.
|
8. Time to Eat! Observations
26 March 2018 Why do we eat? Are some foods better than others? Where does all our food come from? Watch the "How Animals Eat!" video to the write and fill in the Time to Eat! worksheet. |
|
9. It's Called Cellular Respiration
26 March 2018 How, then, do we get energy from the food that we eat? Read the article, watch the video to the right, and answer the questions that go with the article. 27 March 2018
Complete the Digestion System poster page on the back of "Time to Eat!". Use the Digestive System video to the right and the internet (see websites below) to draw the organs (structure) of the digestive system on the gingerbread man on your paper. Describe the function (purpose) of each organ in the margins. How does the digestive system help you get energy from the food that you eat?

10. Cellular Respiration in Yeast (periods 2 and 3 only)
27 March 2018 Today in class we performed an experiment in which we watch Yeast undergo Cellular respiration. Yeast can undergo aerobic respiration (with oxygen) or anaerobic respiration (without oxygen). In bread-making, the yeast starts off respiring aerobically, producing water and also carbon dioxide to make the dough rise. When the air runs out, the yeast begins to respire anaerobically. Any alcohol produced boils away during baking. www.bbc.co.uk/schools/gcsebitesize/science/triple_ocr_gateway/beyond_the_microscope/useful_microorganisms/revision/2/ Watch the two videos. Make observations. Create a graph to visualize your observations (on your worksheet). Complete the analysis and conclusion questions. |

11. Photosynthesis and Cellular Respiration: Draw, Riddle, Analogy
28 March 2018 Use all of your notes/worsheets that we've completed up to this point in order to complete this assignment. Use color. Be creative. Below are some ideas of animal/plant relationships you could use. |

8.3.1 & 8.3.2 Assessment (Photosynthesis &Cellular Respiration)
On Canvas Thursday/Friday, 29/30 March 2018 Quizizz Review: Photosynthesis, Cellular Respiration and Experimental Design The Canvas access code is: photosynthesis |
|
8.3.3 |
I can ask questions to obtain, evaluate, and communicate information about how changes to an ecosystem affect the stability of cycling matter and the flow of energy among living and nonliving parts of an ecosystem.

Introduction to 8.3.3: Ocean Sunlight
9 April 2018 http://www.tv411.org/science/tv411-whats-cooking/video-photosynthesis?gclid=CO7Z4oPos7UCFShgMgodLloAtw
Today we read a book "Ocean Sunlight". Watch the video to the right. What would be the consequences if all of the ocean's phytoplankton were suddenly gone? Is there any organism that we could do without? Explain your answer. |

13. Food Chains and Food Webs
Tuesday, 10 April 2018
If you were absent, start by looking at the cards (click the link; you may want to print them and cut them out so you can more easily organize them).
1. Separate them into two groups. What criteria did you use to make your two groups?
2. Watch the videos below (#3 at least). As you watch, write down the definitions for producers, consumers and decomposers.
3. Separate the pictures into producers, consumers and consumers. List them on your paper under the definitions.
4. Choose one of the producers to start a food chain in the middle of your paper. It should include at least one herbivore and one other consumer (carnivore or omnivore).
5. Flip your paper to the back. Create a food WEB using all of the organisms on the cards. Include ALL arrows that show the flow of energy.
