Only If They Think They Can Get Away with It?

Science Fair Project Idea

Scientific Method

How many times have you seen a car without the appropriate permit (either a license plate or placard that hangs from the rearview mirror) parked in an accessible parking space reserved for people with disabilities? If you find this behavior upsetting, you might be interested in figuring out how to discourage "cheaters" who use these spaces to make a quick trip into the store. Is it enough to let them know someone might be watching? Read more

Out of Control!

Science Fair Project Idea

Scientific Method

Have you ever watched an inexperienced video game player pick up a controller and start playing a game? Often the player bumbles around trying to figure out which button makes the onscreen character jump, run, turn left, or perform other actions. Some games are different though, they have control schemes that are more real-world based. For example, most modern Mario Kart games give you the option of steering with a joystick or turning the entire controller like a steering wheel, which is more… Read more

Ozone Depletion

Science Fair Project Idea

Scientific Method

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do… Read more

Paintball Ballistics

Science Fair Project Idea

Scientific Method

Have you ever played paintball with your friends? Wonder how you can improve your game? Paintball guns use compressed gas to shoot paint-filled pellets at high speed, and with good accuracy. The flight path of the ball is determined by its speed and the angle at which it is shot, relative to the ground. In this sports science fair project, you will explore the ballistics of paintballs, focusing on how drag and other factors affect the results. Read more

Paper Maze Programming: Start to Finish Computer Logic

Blog Post

Explore the logic of computer coding — no computer required! Have you ever asked your student to give you directions, turn by turn, to get you home from a familiar landmark? It can be eye opening to hear how they might guide you, and you may or may not make it where you need to go! But the process of giving directions helps reiterate the steps involved in moving along a frequent path. Writing a computer program is similar in many ways. You need… Read more

While you might enjoy cranberry sauce, if you’ve ever tasted a real cranberry you were probably surprised by the taste – definitely not as sweet as the sauce! Cranberries and cranberry juice are very tart to eat, but they can be delicious when combined with other ingredients (such as orange zest and sugar, or cranberry muffins!). Cranberries add tartness to these foods because they are acidic, similar to lemons or limes. Foods that are acidic will usually taste sour or tart,… Read more

Pastry Science: Weekly Science Activity

Blog Post

In this week's spotlight: a food science activity that may fit right in with any baking you have planned for the season. Are pies on your family's list of favorites or traditions this time of year? How do you like your crust? Does your mouth water for a flaky crust on a homemade pie? In this kitchen science experiment, families can explore the role of fats—and the temperature of the fat—on the texture of a pie crust. When you get ready to mix up a crust, do you take the… Read more

Pedalism and Movement

Science Fair Project Idea

Scientific Method

Humans are bipedal, which means we walk using two legs. This gave humans an adaptive advantage during the evolution of humankind. Being bipedal gave humans additional speed, balance and flexibility used for walking, hunting or traveling long distances. However, we may have lost the ability to climb or swing in trees like other primates. How much faster can you go when you are bipedal? Have a race with your friends using two legs, and then four legs (use your arms as your 3rd and 4th legs).… 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

Pet Poll: A Taste Test for Fluffy & Fido

Science Fair Project Idea

Scientific Method

Has your dog ever barked, seemingly for no reason at all? Or has your cat ever stopped and carefully smelled a spot that looked perfectly clean to you? Pets, like people, have senses that they use to learn about and to react to their world, but their senses can be stronger or weaker than people's. In this mammalian biology science fair project, you'll study your pet's sense of taste by conducting taste tests and watching how your pet acts to determine his or her favorite type, flavor, or brand… Read more
