Plants can't move around like animals, but they can grow toward light. You can test this yourself with a plant at home!
๐งช What you'll need
* ๐ฑ A small potted plant
* ๐ฆ A cardboard box
* โ๏ธ Scissors
* โ๏ธ A sunny window
* ๐ A ruler
๐ฌ Try it at home!
1. Make the box
Cut a small hole in one side of the cardboard box.
2. Add the plant
Put the plant inside the box. Make sure the hole is facing a sunny window.
3. Wait
Leave the box near the window for 3โ5 days. Try not to move it.
4. Check your plant
Look at it each day. Is it growing straight, or is it bending toward the hole?
5. Record your results
Use a ruler to measure the plant each day and write down what you notice.
๐ What will happen?
After a few days, you may see the plant bending toward the light! โ๏ธ๐ฑ
This is called phototropism. It's a plant's way of responding to light as it grows.
