 Hi Gr.7s!
As you know, we are studying the transfer of energy in ecosystems this week.  Click on the following link and scroll down to the middle of the page to the Energy Pyramid. Read the caption and click on the energy pyramid link. It will connect you to a cool video that explains the energy transfer process in a food chain.
There is also a link at the bottom of the page to a BrainPOP video about food chains that you should check out.
Next, click on the "Create a Food Web" link and follow the instructions to create a food web displaying the transfer of energy. Print out your web and bring it to school when you are done.
Click on the Food Chains MCQ link at the bottom of the main page. Complete the quiz, print it out, and bring it to school.

Hello Parents!
We are currently studying the Life Systems: Interactions in the Environment science unit. Your child is expected to complete the activities outlined above in efforts to meet the following curriculum expectation:
Understanding Life Systems: Interactions In the Environment
3.4 describe the transfer of energy in a food chain and explain the effects of the elimination of any part of the chain
Please encourage your child to review the information and videos that were assigned to them. The information is very helpful and will reinforce the concepts they are learning in class. If you feel as though your child will benefit from additional opportunities to learn and reinforce the concepts, please direct them to the Worksheet Menu link at the bottom of the main page. It will take them to a page with 6 interactive activities under the title of Food Chains and Webs. Have your child complete some of these activities to develop their understanding of energy transfer in ecosystems.
