Ecosystem Explorers: Who Eats Whom? 🦉

Fifth Grade Families,

Our scientists have been outside with their notebooks this week, studying the whole ecosystem. We have been learning how plants and animals in a habitat depend on one another, and what happens when one piece of the puzzle changes.

What we did in class. Students sorted organism cards into producers (plants that make their own food), consumers (animals that eat plants or other animals), and decomposers (the fungi and bacteria that break everything down). Then teams used yarn on the floor to build a giant food web for a Virginia forest. When I "removed" the oak tree by pulling one string, students could see how many other strings went slack. That was the light-bulb moment of the week.

Outdoor investigation. We spent part of one afternoon on the school grounds recording every living thing we could find in a one-meter square, from clover to ants to a very surprised cricket. Back inside, students identified each organism's niche, its role in the community.

Big idea. We also talked about how people change ecosystems, for better and for worse, and each student wrote one way they could help protect a habitat near home.

How you can help at home. Pick any animal your child likes and ask, "What does it eat, and what eats it?" Then ask, "What would happen if that food disappeared?" You will be amazed at the chain of reasoning that follows.
