1 FOOD CHAINS UNIT: Ecosystems and Energy TARGET(S): I can draw a food chain. I can describe examples of how organisms interact with their environment and each other. I can explain that some interactions are beneficial and others are detrimental. investigating What question will students be investigating? How will the investigation guide student understanding of the science learning target? Watch a video about food chains within an ecosystem: v=3bn7wdcp2v4 Cut out organisms and cre a food chain (mobile, mini-poster, linked). talking What types of questions and structured talk will guide student understanding of the learning target? How will you encourage student talk? Students think-pair-share about organisms they observed during the video and describe the feeding relationships. Students describe their food chain to a partner. Extension: interactive website on food webs: activity/food/food_menu.html reading Which reading will enhance or extend student understanding of the science learning target? How will you model and support student reading? Read texts about ecosystems that include specific organisms and their feeding relationships. For example: Treasures: Desert Habitats. Pass the Energy, Please! by Barbara Shaw writing How will students communicate in writing their understanding of the science learning target? How will you model and support student writing? Write a brief informative/explanatory essay that describes the food chain within an ecosystem.
