When it comes to making ice cream, in order to make the mixture cold enough to freeze, you surround the container with ice and rock salt. This experiment helps you learn how the addition of salt (or other substances) affects the freezing...

In a bioassay, a living organism serves as a detector for toxins-the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay...

The goal of this cooking and food science fair project is to understand how processed cheese is made, and to determine which percentage of emulsifying salt produces the best processed cheese. The Science Buddies project ideas are set up...

Here is a monumental list of ideas for science fair projects and experiments, organized alphabetically. Every one of them is a link to a full page, with pictures, of information about the idea. This site is a goldmine.

Science Bob provides instructions for setting up an experiment to show how to grow bacteria.

In this science fair project, experiment with the role temperature plays in the rate at which UV beads lose their color. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

Experiment with the chemical called luminol, which emits a blue light when it reacts with other chemicals. This science fair project explores whether temperature affects the amount of light emitted. The Science Buddies project ideas are...
