-Synthesize science learned in previous grade levels to build a more complex understanding of the role energy plays in ecosystems.
-Understand that energy never disappears or is created from nothing; all energy must obey the rules of the universe set forth in the LAW OF CONSERVATION OF ENERGY
Today was a “BIG IDEA” day in which we pulled everything students should know from elementary and 6th grade about food webs, and combined it with new knowledge to create this really in depth understanding of how energy flows through ecosystems.
Here’s the PowerPoint that started it all:

From there we looked at the roles that Mitochondria and Chloroplasts (6th grade material) play with Photosynthesis and Cellular Respiration (8th grade material).
Students ended the day by trying to figure out how to tie food chains they learned about in 5th grade together to make food webs… with the ingredients in a Tootsie Roll that they just ate (corn, sugarcane, soybeans, cows… etc.). From what I’ve seen so far in “A” Day, it will be worth our time to learn about Food Webs rather than skip the material.
Lastly, I wanted to give a shout-out to a certain Avatar in fourth period that really gave us some great conversation today: SwaggyCookies, thanks for the great discussion.
