Improve the design of a very simple aircraft, the whirlybird, and learn about hydrodynamics and biomimicry in this science experiment. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

A simple science fair project to test whether electricity can flow between two things. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms,...

When you think of a machine, you probably think of computers or robots. Try this experiment to see how simple machines are used everyday around your house.

In this science fair project, measure the strength of tea, using plastic cups, a photoresistor, and a multimeter. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed...

Music boxes, bicycles, and clocks all have one thing in common: GEARS. You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in...

After building a simple electric motor from a kit, with this experiment you can explore how voltage affects motor speed. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

By making a simple sled kite from the template provided and using the suggestions in the Science Buddies project, you can experiment with variables that test different aspects of flight. The Science Buddies project ideas are set up...

This chemistry science fair project uses a very simple experimental setup - a battery hooked up to two solutions, connected by a salt bridge - to explore some complex chemistry. The Science Buddies project ideas are set up consistently...

Iron is an important mineral essential for good health. Iron deficiency can be a problem. In this science fair project, use a simple iron test kit to measure the concentration of iron in water. This experiement is explained clearly and...

This is a modern version of a classic experiment by Robert Boyle on the compressibility of gases. Boyle discovered the relationship between pressure and volume of gases that now bears his name. This project shows you a simple method for...

This is a modern version of a classic experiment by Jacques Charles on the volume of a gas at different temperatures. Charles discovered the relationship between volume and temperature of gases that now bears his name. This project shows...

Did you know that cosmetic companies employ teams of specialized chemists to develop and test each new line of make up, perfume, lotion, or soap? Here's a project that lets you be the cosmetic chemist. It shows you how to manufacture...

Though rock candy seems to be a simple enough treat, it is also pretty interesting to make. Crystallized sugar that can be grown from a sugar-water solution is just how rock candy is made. In this experiment, you will learn to make your...

Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one...

Can you pat your head with one hand while you rub your stomach with the other? This experiment is kind of like that, but it can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough,...

This is an experiment that explores certain aspects of how your brain pays attention. In this project, you'll have to recruit volunteers to take a simple test: naming a list of printed shapes. What makes the test tricky is that words...

Shake N' Light flashlights have been advertised on televisions across the nation in the recent year. But many do not understand just how they get energy to light up the bulb without using batteries. Do this experiment to make your own...

The human body has proprioceptors that send signals to the brain so that we are aware of our body's position and movements. Try these simple experiments to learn about proprioception and about other visual and tactile clues that assist...

A simple experiment where pennies are thrown, then half are removed, to simulate how radioactive decay works.

Model the process of transcription and translation with this simple activity using cereal chains.

An online activity which illustrates the magnetic property of diamagnetism associated with water. Contains a simple procedure and then a good explanation of the magnetic interactions that were displayed by the grapes.

Use common supplies to try a simple experiment involving chemical reactions.

A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

A simple lab activity to demonstrate that ocean currents are influenced by changes in water density.
