Human Impacts on Earth.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Living things break the rules of non-living things — find the rule they break.
Mind = Blown
🦠 You have more bacterial cells in your body than human cells.
Make a hypothesis first
Predict: what will happen to the plant if you change the water?
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.
Key Words
- data
- observation
- experiment
Materials Needed
- cups
- aluminum foil
- ruler
- markers
- popsicle sticks
- pennies
Safety First
- Wash hands after handling materials.
- Be careful with scissors — ask an adult for help if needed.
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?

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.”
