Ecosystems.
🎯 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
Plants have specialized structures: roots anchor the plant and absorb water, stems transport materials, leaves capture sunlight, and flowers produce seeds for reproduction.
Key Words
Tap a word to see its definition.
Materials Needed
- water
Safety First
- Never look directly at the Sun or into a laser, even briefly.
- Mop up spills straight away so nobody slips, and keep liquids away from sockets.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Design a controlled experiment: grow plants under different light conditions (full sun, partial shade, no light). Water equally and measure growth daily for one week.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
