How Food Supplements Affect Weight Gain of Juvenile Mice

Science Fair Project Idea

Scientific Method

As your mom and dad always tell you, a healthy diet is important to good health. This project is designed to see what happens to mice when they are allowed to load up on sugary snacks. Do you think that they will gain excess weight? Do you think that the mice will regulate their own intake and maintain a 'healthy' diet? You can try this project and find out for yourself. Read more

From Your John to the School Lawn: Is Recycled Water Really Safe?

Science Fair Project Idea

Scientific Method

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more

Drag Racing in the Water

Science Fair Project Idea

Scientific Method

It's fun to go swimming! To feel the power of your body as you launch yourself into the water. But did you know that swimming isn't just about skill and athleticism? The human body consists of skin, contours, and curves. How the water moves along your body and the clothing you are wearing determines how fast you can go. In this science fair project, you will investigate the effects of a force called drag. You will compare the time it takes to swim 25 meters in a swimsuit versus swimming the… Read more

Skeleton Building

Science Fair Project Idea

Scientific Method

Do you like skeletons? One of the more interesting jobs at a natural history museum is the creation and care of the skeletons and bones. How do the curators clean and put together the skeletons? Many curators use the carrion beetle, Dermestes vulpinus, to quickly clean off the dead animal tissue from a corpse to reveal the skeleton. These insects do such a good job that sometimes the skeleton remains intact! Another method is to slow cook the carcass until the meat falls off. You can use… Read more

Perfect Plating: Which Food Presentation Technique is Best?

Science Fair Project Idea

Scientific Method

Did you know that people eat with their eyes as well as with their mouths? Food presentation—also called plating techniques or garnishing—makes food appear more appetizing. Checking out how the food looks is the cook's last task and the diner's first. Food that is well-presented is beautiful, colorful, and captivating. Not only does it make the diner really want to eat, but good presentation also allows the diner to identify the food ingredients, their quality, and the technique… Read more

What is the Rate of Leaf Growth Along the Stem?

Science Fair Project Idea

Scientific Method

Leaves grow in a different pattern than stems and shoots. They do not elongate along one axis, but instead spread out over time. Do all regions of the leaf grow equally? You can use markings on different regions of a growing leaf to see if the whole surface grows, or if growth is focused in a particular region, like the veins or edges of the leaf. If you look along a leafy stem, you may notice that leaves at different positions along the stem are different sizes. You can do an experiment to… Read more

Respiration and Gills: What Factors Affect Respiration in an Aquatic Environment?

Science Fair Project Idea

Scientific Method

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… 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

Squishy Robot Simulator: Physics Settings

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, we provided you with a template file that included default material properties and physics simulation settings. These settings include friction, gravity, and temperature — all of which can drastically change how fast your robots move. However, we did not explain what exactly all these physics simulation settings meant, or how to change them. You can access the physics settings through the Physics Settings tab after entering the Physics Sandbox mode, as… Read more

Tasty Arrangements: How to Position Food in Microwave Cooking

Science Fair Project Idea

Scientific Method

When you think of successful inventions from the 1900's that have dramatically changed how people live, what comes to mind? The car? Radio? TV? The computer? What about the microwave oven? You might not remember a time when microwave ovens were not a standard part of most kitchens, but your parents or grandparents probably do. They can remember when heating leftovers took a good 30 minutes in a traditional oven. Or thawing a food from the freezer meant leaving it in the refrigerator overnight.… Read more
