Phototropism: Why Do Plants Grow Toward Light?

Plant Biology Elementary Science Fair Project

For those elementary students interested in botany, this cool experiment from Plants for Kids is a great way to discover and study the effects of phototropism - i.e. the way a plant grows in response to light. While you may have already discovered that plants grow toward light (a concept known as positive phototropism), by creating a plant maze, you'll be able to actually demonstrate this concept as you hypothesize and research both why and how a plant will wind its way through the maze in order to reach the light at the top!

Plants for Kids has a great tutorial for creating a plant maze from simple household items so, to get started, be sure to visit their project page!
