In this experiment, kids will see if pruning tomato plants makes them more fruitful and learn about the factors that contribute to a plant's fruit production.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

Science fair project about work and energy which uses a simple mathematical formula to predict how far a jar will roll down an incline.

Explore if planting seeds in a certain direction will affect how fast it germinates.

This science fair project idea investigates how the shape of an object affects drag.

This science fair project investigates why the number of visible stars changes from place to place.

Get down to the rubber with this science project that tests the effectiveness of different types of erasers.

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

Will storing cucumbers and tomatoes in the fridge destroy their unique flavors? Find out in this science fair project idea!

Science fair project which determines whether it is numerically possible to be connected to every person on the earth within six degrees of separation.

Find out which kind of bubble wrap fares best when put in impact.

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

This science fair project will help students learn about non-vascular plants, such as mosses.

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.

In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

This science fair project idea explores whether white light can be separated into different colors.

How well can people recall what they have observed. Test your knowledge in this fun experiment.

Soil is made up of different layers. How far down do you need to dig to find the soil horizon, or the place where bits of leaves and branches become soil?

Using a toy race car kids create a visual model of the Doppler Effect.

This science fair project idea explores whether a sundial is as accurate as an atomic clock when telling time.

This science fair project idea explores whether color affects a person's emotional state.

In this science fair project, students examine under what conditions individual plants release seeds and how far the seeds are released.

Tree rings can tell the age of the tree but also information about the world. This science experiment uses tree stumps to discover new facts.

What keeps a an item cooler, polymer crystals or ice? Find out in this cool science experiment!

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

What animals are most popular? This project affords practice in data-collection, record-keeping and data-analysis through the investigation of this question.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.
