12/10/15 and 12/11/15 1.Food Web Activity (10.2) 2.Semester Exam Review 3.Scientific Explanation (due at 11:59pm) HOMEWORK: Optional: Reading 10.3 (IQWST) and Semester Exam Review (paper and digital copy on Google Classroom)

Learning Goals Create an initial model of how matter cycles through an ecosystem.

Activity 10.1-How does matter transfer between organisms? Use your foldable, notes, video facts to complete the chart in the procedure section. Think, Pair, Share

Activity 10.1-How does matter transfer between organisms? (1 st, 2 nd, and 3 rd ONLY) Analyze as a table: Copy and answer the following questions in your binder (next available page). 1.Compare the way that plants and animals get their food molecules. 2.Compare the chemical reactions that plant and animal cells use to provide energy. 3.Compare how plants and animals get the energy to do things. What chemical reactions are involved? 4.Compare types of energy plants and animals can use. 5.How do you think that plants and animals are dependent on each other? Justify your answer.

Activity 10.1-How does matter transfer between organisms? Analyze as a pair: (using paper provided) Work with someone who has on a similar color shirt as you. Sketch a model (use arrows) showing how the substances involved in cellular respiration and photosynthesis cycle in this environment. Carbon dioxide Water Food molecules Oxygen Cellular respiration Photosynthesis Plants (can be used more than once) Mouse Share using the document camera.

Learning Goals Model carbon transfer in an ecosystem. Model energy flow through an ecosystem.

Activity 10.2-How does energy move between organisms? What do you know about food webs?

Activity 10.2-How does energy move between organisms? Responsible for one organism in a food web per table, and will later come together as a class to create a model of how energy flows, and matter is transferred, through the ecosystem.

Activity 10.2-How does energy move between organisms? Table 1: algae Table 2: mice Table 3: aquatic insects Table 4: foxes Table 5: aquatic plants Table 6: hawks

Activity 10.2-How does energy move between organisms? On easel pad paper, draw your organism in the middle. Answer questions 1-8 (IQWST-Activity 10.2) on your easel pad paper. List 5 facts about your organism. Draw the movement of carbon-containing molecules through their organism on your paper.

Activity 10.2-How does energy move between organisms? Add the following energy labels to your model: Light energy Food molecules (that can provide energy) Kinetic and thermal energy

Activity 10.2-How does energy move between organisms? Make sure your model shows the following: Plants use light energy during photosynthesis Food molecules can provide energy Organisms release kinetic and thermal energy after cellular respiration that cannot be used by other organisms.

Big Question (for Scientific Explanation) How Does Food Provide My Body with Energy? Final Due: December 10 th and 11 th Requirements: Claim Evidence (minimum of 10)-one or more from each lesson Reasoning

Pack everything up. Please put markers/crayons/col ored pencils back where they belong.
