Human Impacts on Earth.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
What the body does in one minute is wilder than any cartoon.
Mind = Blown
🐙 An octopus has 9 brains and 3 hearts.
Make a hypothesis first
Guess: how does the body solve this problem?
What You'll Learn
Engineers must consider constraints (limitations like cost, time, and materials) and criteria (requirements the solution must meet) when designing solutions to problems.
Key Words
- criteria
- iteration
Materials Needed
- pennies
- plastic wrap
- cardboard
- tape
Safety First
- Clean up spills immediately to prevent slipping.
- Use materials only as directed in the experiment.
Steps
Read about Human Impacts on Earth and write down three key facts.
Conduct a design challenge: build a car powered only by a balloon. Measure how far it travels and iterate on your design at least twice.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

Where you see this in real life
Your own body is doing this thousands of times every second.
Stretch Challenge
Try this in real life this week.
Find one thing about your body that's different from a friend's. Wonder why.
For the dinner table
“Tell me something you noticed about your own body today.”
