Buoyancy of Floating Cylinders

Science Fair Project Idea

Scientific Method

This science project presents an interesting puzzle. A disk of wood will float face-up; that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats on its side with the circular cross-section perpendicular to the surface of the water. If you think about it, disks and logs are both cylinders. Is there some intermediate length of cylinder that floats with the circular cross-section at a tilted angle? Try this experiment to find out! Read more

Burning Biofuels: Comparing Nonrenewable and Renewable Fuels

Science Fair Project Idea

Scientific Method

Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more

Calculating the Circumference of the Earth

Science Fair Project Idea

Scientific Method

How big a ruler would you need to measure the circumference of the Earth? Did you know that you can do it with a yardstick? (And you won't have to travel all the way around the world!) Read more

Camouflage Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of zoology science projects that let students and families explore how some animals use camouflage so they can better blend in with their surroundings. Does camouflage really make a difference when it comes to the relationship between predators and their prey? Give it a try in fun hands-on science activity using M&M® and Skittles® candies. If you are a hungry predator trying to grab a specific color of M&M, how hard will it be to find your… Read more

Can a Toilet Paper Tube Support Your Weight?

Science Fair Project Idea

Scientific Method

Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold… Read more

Can Copper Foil Snails?

Science Fair Project Idea

Scientific Method

If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. Read more

Have you ever poured sand out of a bucket, or poured cereal out of a box, and noticed it is a lot like pouring water? It is because sand and cereal are granular materials. This means they are made up of solid particles, but they can actually flow like liquids! Candies, like Skittles®, M&M's®, Nerds® candies and many others, are also granular materials. In this science activity, you will investigate how the size and shape of granular materials affect how they flow. And what… Read more
