When you cut a flower to put into a vase, it'll eventually wilt, even with water and sunshine. But is there another scientific secret to keeping flowers fresh?

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.

This science fair project teaches students the differences between fruits and vegetables.

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.

Discover whether cold or hot water from the faucet will boil faster on the stove.

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

What is topography? Kids find out by learning to make and read a topographic map in this awesome science fair project idea.

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.

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

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

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

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.

Want to see a great example of Newton's first law? Kids will learn about basic physics with this fun, ballistic experiment.

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

How does salinity affect the point at which water freezes? Kids will find out by performing this cool melting ice experiment.

This science fair project idea explores the egg's thin membrane.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

Learn how to make a food pyramid with animals in a a coniferous forest ecosystem around your home.

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.

Make a backbone model to explore human anatomy and life science.

In this project, all you need is a protractor to learn how to use the altitude of Polaris to find latitude on Earth. Polaris is also known as the North Star.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.
