Food chain -
Paige and Kelly worked together to work a food chain lab. We used test tubes to illustrate how energy moves up the food chain. Plants convert solar energy into usable chemical energy, but only 10% of is transferred to the first level consumers. From that, herbivores use 90% and carnivores can absorb the remaining 10. The test tube lab illustrates how important it is to eat mostly plants and animals that are fed plants. We discussed what a good diet means to a health future. The girls then worked together on a game of food fight. While they built a food web, we discussed the environmental concerns for each species they added to the process. We worked out the food web for top predators, and again for first level consumers.
