Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

Let your kid experiment with textures among fabric and other materials that are smooth, rough, soft, or slippery—and then they'll make a texture book!

This science fair project idea produces sounds by creating vibrations using different objects.

Use this fun activity to make an optical illusion picture that helps your kindergartener explore the sense of sight, and sharpen his observation skills!

Here is a kindergarten activity that blends art and science by using magnets, paint, and objects found around the house to create a picture.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

This science fair project idea produces varying pitches of sound.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

Learn how to be a bird scientist in this simple project of watching feathered friends in their habitat.

This science fair project idea demonstrates that light travels in straight lines and experiments with reflecting light.

Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

Checkerboard play challenges students to use spatial reasoning and computational thinking.

Try this fun garden graphing project with your kindergartener this summer to give him a leg up in math and science while spending some valuable time outdoors!

This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

Can a horse lead itself to the carrot? Train your horse with carrots and boxes and test horse memory in this fun zoology science fair project.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

For your budding first grade scientist, all you need is some simple, natural materials to create an amazing ant farm. Here's how to get started.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

This activity is a fun challenge for students who have just started learning to program educational robots.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

Here's a science activity to help your child investigate how seeds are designed to travel.

How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot navigate around several obstacles.
