In this science fair project, apply the principles of leverage and force by building six simple machines designed to set weights in motion.

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?

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

Does putting soapy water on plants help or hinder plant growth? Kids learn about greywater and how it affects plant growth in this cool science fair project.

In this experiment you observe and determine how well your cat uses his whiskers to navigate through a maze.

Design a survival kit. Brainstorm various survival scenarios. Address basic human requirements and natural resources. Describe each tool as well uses.

Kids will learn how to measure the viscosity of liquids by making their own homemade viscometer in this great science fair project idea.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea.

This science fair project idea examines the reason boats are shaped and engineered.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

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

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

Examine the effect of pressure on carbonation in soda.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

In this science experiment, your child will test the strength of hollow structures in order to understand how strong bird bones really are.

Science fair project that examines the different types of precipitation, evaluates the density of snow and calculates the ratio of snow-to-liquid.

The objective of this science fair project is to study the photosynthesis process and demonstrate the important role that leaves play in the process.

The purpose of this science fair project is to build a basic radio.

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

The goal of this science fair project is to demonstrate different ways to generate static electricity and record its effects.

Is there a relationship between caffeine and heart rate? Students will determine the effect of caffeine on heart rate in this fun science fair project.

In this science fair project, students use the streak test to tell minerals apart from each other.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

Create a DIY Electromagnet! Using a 9v battery to create an electrical field around a nail, students explore electromagnetism in this cool science project idea.

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.”

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.

In this science fair project, students create their own miniature salt flats at home.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.
