What causes the seasons to change? Kids find out by modeling the earth's tilt using a globe, flashlight and graph paper in this cool science fair project idea.

In this science fair project, young children notice and track changes in trees throughout the year.

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.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

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

Science fair project that determines whether landscaping fabric impacts the ability of plants to receive water.

In this activity, your child will be challenged to create a device that protects an egg when it is dropped from a height of about 10 feet.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

Show your preschooler how to make a print of a butterfly using her hand as a tool--a great way to stimulate her sense of touch.

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.

This science project has students collect wood samples and invent new uses for different types of wood based on its properties.

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

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.

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.

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

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.

Make your own greenhouse - out of a balloon! Your child will learn how greenhouses work as they plant radish seeds and watch them grow.

In this activity, your student will be invited to build a chair out of building blocks that is designed to meet the specific size and shape of a small doll or toy figure.

In this activity, students will create a stop motion animation by creating a clay figure and taking a series of digital photographs.

Students explore hot desert plant adaptations in this cool science fair project by observing how these organisms prevent excessive transpiration.

This activity challenges your student to use spatial reasoning and computational thinking to program multiple robots.

In this activity, students will be challenged to describe and count the ways a toy moves from one position on a grid to another.

Blend art and science in this hands-on activity that shows your kindergartener how primary colors combine to make secondary colors.

Create a homemade pair of sunglasses with colored lenses to see just how light and color affect our sight! Use this fun project to practice science!
