Human Impacts on Earth.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
Every species solves the same problem differently.
Mind = Blown
🌳 Trees can talk to each other through underground fungus networks.
Make a hypothesis first
Before you watch: what do you think it'll do?
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
- wavelength
Materials Needed
- cups
- aluminum foil
- ruler
- markers
Safety First
- Wash hands after handling materials.
- Be careful with scissors — ask an adult for help if needed.
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.
Check Your Understanding
Question 1
1 of 3What is peer review?
Where you see this in real life
This is why plants grow toward windows and why scabs form.
Stretch Challenge
Try this in real life this week.
Watch a plant or pet for 5 minutes today and write down what you noticed.
For the dinner table
“Tell me something you noticed about your own body today.”
