Human Impacts on Earth.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
What the body does in one minute is wilder than any cartoon.
Mind = Blown
🦠 You have more bacterial cells in your body than human cells.
Make a hypothesis first
Guess: how does the body solve this problem?
What You'll Learn
Engineers use the design process to solve problems: identify the problem, research, brainstorm solutions, build a prototype, test it, evaluate results, and improve the design.

- control
- data
Materials Needed
- cups
- aluminum foil
- ruler
- markers
Safety First
- Protect your work surface with newspaper or plastic.
Steps
Study the diagram and label the parts you recognize.
Create a solar oven from a pizza box lined with foil. Measure the temperature inside on a sunny day. Try melting chocolate or cheese.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?
