Make a hypothesis first

Before you start: write down what you think will happen, and why.

Say your guess out loud — then find out if you were right.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Create a detailed food web for a local ecosystem. Include at least 8 organisms and use arrows to show energy flow from producers to top predators.

Step 3 of 4 · Observe

Compare the before and after states.

Step 4 of 4 · Record

Write your conclusion: did the results match your hypothesis? What would you change next time?
