This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

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.

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

In this windmill model science project, you will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.

This simple "how to make a water wheel" activity makes physics come alive for your child by demonstrating how different kinds of energy work.

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

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

Jazz up your patio or backyard with hip and quirky planters made from simple Mason jars.

This science fair project idea explores whether a plastic slinky works as well as a metal slinky when walking it down the stairs.

Science isn't ho hum anymore when it involves building catapults to teach your fifth grader about projectile motion.

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.

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.

This science fair project idea explores how length affects the weight a bridge can hold.

This science fair project demonstrates the magic of arches by challenging students to stack telephone books on top of eggs without breaking them.

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

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.

The objective of this science fair project is to test the growth rate of a plan in a crystal medium in comparison to traditional soil.

What is a wedge? Kids find out by experimenting with different wedges in this simple science fair project idea.
