The Moon and the Stars

Science Fair Project Idea

Scientific Method

Everyone loves looking at the full moon, but are these nights the best time to go stargazing? Can the moon interfere with certain astronomical observations? Read more

The Nose Knows Smell but How About Taste?

Science Fair Project Idea

Scientific Method

Ahchoo! Got that stuffy nose and I-can't-breathe kind of cold? Those sniffles and clogged sinuses are bad enough, but why does it also seem everything tastes so bland and flavorless when we are sick? Is there really truth to the idea that smell is a key part of taste? Gather up a few volunteers, hit the kitchen, and try this experiment to find out. Read more

The Physics of Artificial Gravity

Science Fair Project Idea

Scientific Method

How can we make space stations with artificial gravity a reality? In this science project, you will explore the physics of creating artificial gravity with circular motion. Read more

The Physics of Baseball and Hit Charts

Science Fair Project Idea

Scientific Method

In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Have you ever seen a game-winning “Hail Mary” pass in a football game, a baseball player throw in a ball from way out in the outfield, or a soccer goalie punt a ball all the way down the field? All of these actions involve a player trying to throw or kick a ball as far as possible. There is some sports science behind these throws and kicks – how do you know what angle to throw or kick the ball so it will go the farthest? Should you make a shallow throw (straight out, parallel to the ground), a… Read more

The Process of Soft-Boiling an Egg

Science Fair Project Idea

Scientific Method

Sometimes on a busy day, it is hard to get things done. The rush to get things done can start first thing in the morning, when you are so busy getting ready and gathering your homework, that you barely have time for breakfast. It takes time to get a nutritious meal ready. But, eggs are a perfect choice for breakfast because they can be cooked quickly and in many different ways. A soft-boiled egg is a choice that many people make. They like the way the thickened, tasty yolk coats their hash… Read more

The Role of Fats in Making a Delicious Pastry

Science Fair Project Idea

Scientific Method

Apple pie is one of America's traditional desserts. It can be enjoyed on its own or with a scoop of vanilla ice cream. The cool sweetness of the ice cream combines with the warm apples and flaky pastry to create a taste sensation. However, if the pastry that surrounds the apples is heavy or chewy then that can really affect how much you enjoy this treat. But how do you make a pastry that is light and flaky? In this cooking and food science fair project, you will find out by experimenting with… Read more

Pollination and seed dispersal are both crucial processes in a plant's reproduction cycle. These processes are helped along by many factors, including different animals. For instance, some animals disperse the plant seeds, while others transfer pollen from one flower to another. In this lesson plan, students will investigate the interdependence between plants and animals for pollination and seed dispersal by creating interdependence webs out of yarn. Based on their created interdependence webs,… Read more

NGSS Performance Expectations:

2-LS2-2. Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

The Science & Reflexes of Dizziness

Science Fair Project Idea

Scientific Method

Tilt-A-Whirls, Merry-Go-Rounds, Spinning Tea Cups...does just the thought of them make you dizzy? Why should something so fun make our heads spin so long even after the ride has stopped? Learn about spins, turns, and the mixed signals that fire in our brains when the sensation of dizziness takes over. Weak stomachs, beware. This project has tests that will make your head spin!
