Demonstrating Photosynthesis: Writing in Grass
This experiment provides a concrete and striking illustration of photosynthesis.
Problem:
Does blocking the sun from a section of grass create an imprint in the grass?
Materials:
- Large piece of fabric
- Scissors
- Many bamboo skewers
- A patch of grass that will NOT be walked upon (This is important as stepping on the bamboo skewers could cause injury.)
Procedure:
- Cut the letters of a name or word (or another image, e.g. a heart, a star) out of the fabric.
- Lay the fabric letters flat on the grass spelling out the word.
- Use the bamboo skewers to pin the fabric in place.
- Wait several days.
- Remove the fabric. Is the word imprinted on the grass?
