This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.

Ethanol can be used as an alternative fuel! The purpose of this experiment is to identify a starch plant that produces the largest quantity of ethanol.

Culverts transport seeds away from their original location to different places. This science project examines the effect of culverts on plant growth in streams.

The purpose of this science project is to determine which stimulus, gravity or water, will cause the greatest growth response in a plant.

Find out whether putting something on top of a plant will inhibit its growth.

What are the effects of fertilizer on plant growth? What's the best fertilizer type (solid, liquid or powder)? Kids find out in this science fair project idea.

This science fair project idea explores whether talking to a plant will help it grow.

Hone your child's skills of observation and take a look at forensic science for an interesting afternoon of exploration and detective work!

This science fair project idea explores plant growth from a bulb, root, and a stem and investigates asexual plant reproduction.

Take a look at forensic science with your child. She'll learn how to take a shoe impression, just like the detectives do!

This first grade science activity is great for winter! Your child will grow and observe her own amaryllis bulb, keeping a journal of her scientific findings.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

The project investigates the affect music has on plant growth while experimenting with rock, classical and no music.

The garden is the perfect place to practice math and science with preschoolers. Get digging (and counting, sorting, observing at the same time!)

In this science fair project, students examine how the flow rate in a stream affects the growth of aquatic plants.

This science project teaches students about organic farming and the benefits and disadvantages of commercial plant food.
