How Trees Make Oxygen

๐ŸงชLab Brief #34

Ecosystems.

๐ŸŽฏ Your mission

Predict it first. Then prove yourself right (or wrong).

โšก The twist

Living things break the rules of non-living things โ€” find the rule they break.

๐Ÿคฏ

Mind = Blown

๐ŸŒณ Trees can talk to each other through underground fungus networks.

๐Ÿ”ฎ

Make a hypothesis first

Predict: what will happen to the plant if you change the water?

What You'll Learn

All living things share basic characteristics: they grow, reproduce, respond to their environment, and need energy to survive. Plants make their own food through photosynthesis, while animals must eat other organisms.

Key Words

  • community
  • environment
  • nutrients

Materials Needed

  • cups
  • water

Steps

Step 1 โ€” Read

Review the background information on Ecosystems before starting.

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 โ€” Observe

Compare the before and after states.

Step 4 โ€” Record

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