Prove that green plants need light to survive

Suitable For

Grade 1



Time Required

What’s it about?

All green plants need sunlight to make their ‘food’ to thrive and survive, without it, they will die. Without green plants, all life on earth would be unable to survive, as all living things feed on plants or animals that have eaten plants. Thus, one can say that all living things on earth require sunlight to survive. Try this science experiment to prove that plants need light to survive:

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

This science experiment works because plants are able to convert light into energy. A plant takes in water and carbon dioxide through their roots and leaves, which is needed to form glucose, a sugar that living organisms break down to produce energy. Using energy from the sun, plants rearrange water and carbon dioxide to form sugar. This process whereby light is converted into food, is called ‘photosynthesis’.
