Science Fair Project Idea
thumbnail Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge outbursts called 'coronal mass ejections,' or CMEs. This project asks the question: do CMEs follow the solar sunspot cycle? Read more

thumbnail Sunspot activity has been monitored continuously since about 1700. The historical data shows that sunspot activity rises and falls in a roughly 11-year cycle. This project shows you how you can use both graphical and statistical analysis to look for patterns in cyclical data. Read more

Sunspot activity has been monitored continuously since about 1700. The historical data shows that sunspot activity rises and falls in a roughly 11-year cycle. This project shows you how you can use a spreadsheet program to perform both graphical and statistical analysis to look for patterns in cyclical data. You'll learn how to use a t-test, which is a measure of statistical significance. . Read more

thumbnail If you sit under a leafy tree on a sunny day, you may notice spots of sunlight on the ground from light passing through spaces between the leaves. Try putting a piece of cardboard on the ground and examining the spots of light on the cardboard. Even though the spaces through which the light is passing are irregular in shape, the spots on the cardboard are round. What you are seeing, in fact, are projected images of the sun. Light passing through an aperture forms an image. A pinhole camera… Read more

You can measure the diameter of the Sun (and Moon) with a pinhole and a ruler! All you need to know is some simple geometry and the average distance between the Earth and Sun (or Moon). An easy way to make a pinhole is to cut a square hole (2-3 cm across) in the center of a piece of cardboard. Carefully tape a piece of aluminum foil flat over the hole. Use a sharp pin or needle to poke a tiny hole in the center of the foil. Use the pinhole to project an image of the Sun onto a wall or piece… Read more

thumbnail The sun sometimes releases huge bursts of electrified gases into space. These bursts are called coronal mass ejections (or CMEs). When CMEs are directed towards Earth they can generate auroras, the spectacular atmospheric displays also known as "northern lights" (photo by Chris VenHaus, 2001). In this project you'll use images from the SOHO satellite to measure how fast CMEs move. Read more

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Maybe this has happened to you: you're going shopping with one of your parents and the parking lot is really crowded. You're helping out, scouting for an empty space. You see someone heading toward their car, taking their keys out, and you point them out. At last, you're going to get a spot. You wait for the person to pull out so you can park. Does it take them longer because you're waiting? Do they move out faster? Or does it just seem that they do? For information on people's… Read more
