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

Origami

Science Fair Project Idea

Scientific Method

How do you turn a 2-dimensional piece of paper into a 3-dimensional work of art? Origami, the classical art of Japanese paper folding, is loaded with mathematical themes and concepts. What are the common folds in origami, and how do they combine to create 3-dimensional structure? Can you classify different types of origami into classes based upon the types of folds they use? Can you show Kawasaki's Theorem, that if you add up the angle measurements of every other angle around a point, the sum… 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

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

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
