Why do different types of fruits come packaged in different ways? In this project, you will experiment with different ways of packaging fruit to see if it has an effect on the freshness of the fruit. Will a different kind of packaging...

People often draw conclusions from a small number of observations, but how easy is it to draw the wrong conclusion? Here is a simple project that shows the importance of making enough observations before making a prediction.

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....

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.

If you had to choose between having your favorite dessert, going to a movie, or spending the night at a friend's house, which would you choose? This project shows you how you can "ask" a sowbug (or pill bug) a similar question in order...

Do you like to watch outdated science fiction and cheesy horror movies? Many fictional tales of cloned organisms have been created based upon the scientific method for cloning animals or plants. In the real world, the cloning of plants...

When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping-you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is...

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data...

You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other...

Have you ever wondered how a ship made of steel can float? In this project you'll investigate how much weight boat hulls of various shapes and sizes can support without sinking.

The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this project you'll explore how different fiber types...

Everyone thinks their dog's the best, but in the case of smelling ability, all dogs possess super powers. In fact, a dog's nose can be over a 1,000 times more sensitive than a human's. In this project, learn about smell from a dog's...

In this "kitchen chemistry" project about acid/base chemistry, you will measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. As you learn about the pH scale, you will have the chance to make your...

What do the radio, TV, radio controlled cars, and cell phones all have in common? They all use invisible waves to transmit information. Find out which materials block radio waves, and which materials allow radio waves to pass through in...

In this science project, you can investigate how submarines use stabilizing fins to move forward. Exploring friction and buoyant force you will get closer to understanding how these large ships function. Research resources are included...

Washing your hands is the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. This science project investigates which...

There are over 58 million overweight cats and dogs in the United States alone. In this science project you will determine what percentage of the pets you know are overweight and how their weights compare to weight of pets throughout the...

Whether a chick can breathe inside its shell is an interesting question. Every animal needs oxygen to survive, so the chick must get air somehow. Try this science project to discover if the pores in a chicken egg shell allow water to...

Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. If you like chemical reactions that stink and ooze foamy bubbles...

You will devise a way of testing foods for supplemental iron additives in this experiment provided by Science Buddies. Then you will use your design to test different breakfast cereals to see how much iron they contain. The goal is to...

With this project you'll send ping pong balls flying through the air with a rubber-band powered catapult. This catapult makes it easy to reproduce the launch angle, and to measure the amount of force applied to the projectile. Armed with...
