This activity helps students learn more about cameras, and how to take better pictures.

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again. Outfit yourself with a simple handheld laser pointer, a protractor, and Jell-O, and you're ready to get started.

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this...

If you are interested in aerodynamics, wait for a windy day and go fly a kite. This Science Buddies project gives you many ideas to investigate as experiment with shape, size, and ways to fly the kite. The Science Buddies project ideas...

With this Science Buddies experiment, you will see if you can jump farther if you increase the distance you run before you jump The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online...

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow.

If you like to play Tetris then you might like this project. You'll learn something interesting about the mathematics of complex shapes.

The human immune system has various ways of responding to an infection caused by bacteria or viruses. Our bodies produce proteins (antibodies) that are highly specific for the infectious agent as a part of our "humoral" immune response....

This a straightforward, but interesting, project in geometry. It is a good first proof to try on your own. You should be able to figure it out by yourself, and you'll gain insight into a basic property of circles.

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.

In this project, you'll need: a puck, a hockey stick, a tape measure, at least one helper with a stopwatch and an empty rink. Have your friend start the watch just as you make contact with the puck, and stop it when the puck hits the...

Are you a piano player or a video gamer? Then you might have a quick reaction time that can come in handy while playing sports. Find out how to measure your reaction time and compare it to your friends and family with this fun experiment.

Although fractal images can be intriguingly complex, fractals are more than just pretty pictures. In this project, you'll explore the mathematical properties of the famous Mandelbrot and Julia sets. You'll learn about how these images...

This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other....

Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different...

This is a good first-time programming project. You'll learn how to use JavaScript to create a basic calculator program that you can run in your Web browser.

This is a challenging first-time programming project. You'll learn how to use JavaScript to create a simple program to analyze one or more paragraphs of text. Your program will count sentences, words and letters, and report the resulting...

Mysteries and detective stories have been popular since the time of Sherlock Holmes. The solutions to these fictional cases often involve untangling seemingly contradictory evidence from eyewitnesses. This project studies one procedure...

This elegant project employs a scientific approach that is particularly valuable in Environmental Science, but can be applied to other areas as well. The approach has three steps: 1) from your observations in the field, form a...

Find out whether reclaimed water is really safe by following the guidelines of the Science Buddies project.

Here's a project for studying compression waves in different soil types. It uses a homemade wave tank for solids, with a frequency generator, amplifier, and loudspeaker as the vibration source. There are lots of interesting possibilities...

Some proteins are soluble in aqueous solutions and some are not. Insoluble proteins can be a problem because the proteins can form large aggregates in solution which are difficult to purify, crystallize, and use in experiments. Compare...
