Color Theory

Science Fair Project Idea

Scientific Method

Advanced students might want to look for an experiment in the areas of color theory or gamma and light curves. Following web page can help you get started: Color Theory Fundamentals for Digital Photography Read more

Compost Creativity: Try Various Methods and Test Soil Fertility

Science Fair Project Idea

Scientific Method

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does a 'hot' compost pile compare to a 'cold' compost pile, or how does traditional composting compare to worm composting, or vermiculture? Figure 1. Different composting methods yield different soils. In this picture, the soil on… Read more

Computational Exploration of Protein Function

Science Fair Project Idea

Scientific Method

The DNA in our cells contains our "blueprints," but it's the proteins in our cells that do most of the work. The Human Genome Project has allowed us to start reading the blueprints, but we still don't understand what most of the proteins do. This is a fairly advanced project that explores ways of identifying the function of unknown proteins. Read more

Conduct Galileo's Famous Falling Objects Experiment

Science Fair Project Idea

Scientific Method

Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more

Correlation of Coronal Mass Ejections with the Solar Sunspot Cycle

Science Fair Project Idea

Scientific Method

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

Cosmetic Science: Testing Lip Balm Recipes

Science Fair Project Idea

Scientific Method

Did you know that cosmetics companies employ teams of specialized scientists to develop and test each new line of makeup, perfume, lotion, or soap? This science project lets you be the cosmetics scientist. You will create your own lip balm right in your kitchen using a short list of ingredients, then test it, and follow up with some creative cosmetics science of your own! Read more

Counting Sunspots on an Image of the Sun

Science Fair Project Idea

Scientific Method

Make a pinhole projector (see Measuring the Diameter of the Sun and the Moon). Use the pinhole to project an image of the Sun onto a wall or a piece of paper. Do you notice any dark spots on the projected image? Trace the projected image and count the dark spots. Use your pinhole projector to make images of the Sun at the same time of day for several consecutive days. How does the pattern of spots change? Can you use your data to figure out how fast the Sun rotates? Sunspot activity rises… Read more

Craters and Meteorites

Science Fair Project Idea

Scientific Method

Have you ever heard someone say that the moon is made of cheese? Even though the craters on the surface of the moon resemble holes in Swiss cheese, we know that this common myth is not true. Find out how craters are formed and why they are different sizes by doing this simple science project. Read more

Cryopreservation: Freezing Plant Tissues

Science Fair Project Idea

Scientific Method

Cryopreservation—storing seeds in ultra-cold liquid nitrogen—is one method for maintaining plant genetic stocks in seed banks. Can seeds withstand a really deep freeze and still germinate? Read more

Data Models

Science Fair Project Idea

Scientific Method

Math is used by many different types of scientists to model phenomenon and evaluate data from an experiment. By building mathematical models scientists can understand how different physical, chemical, and biological processes are affected by different variables. The most important tools are: making a graph to give a visual representation of the relationships between your variables and making an equation to give a way of computing the relationships between your variables. Find a source of data,… Read more
