Science Experiments You Can Do at Home

Experiments You Can Do at Home

This is a collection of science experiments that you can do at home. These experiments use materials you either have at home or else should be able to find easily.

Bubble Life Versus Temperature Experiment

The purpose of this experiment is to determine if temperature affects how long bubbles last before they pop. In order to do this experiment, ​you need a bubble solution or dishwashing detergent, jars, and either a thermometer or some way to gauge the temperature of different locations. You can conduct other experiments by comparing different brands of bubble solution or other liquids or by examining the effect of humidity on bubble life.

Caffeine & Typing Speed Experiment

The purpose of this experiment is to determine whether taking caffeine affects typing speed. For this experiment, you need a caffeinated beverage, a computer or typewriter, and a stopwatch. Other experiments you can conduct would involve changing the caffeine dose or testing typing accuracy instead of speed.

Baggie Chemistry Experiments

There are several experiments you can conduct in Ziploc baggies using common chemicals. Experiments can explore endothermic and exothermic reactions, color changes, odor, and gas production. The calcium chloride is often sold as a laundry aid or road salt. Bromothymol blue is a common pH test chemical for aquarium water testing kits.

Analyze the dyes used in your favorite candies with paper chromatography using a coffee filter, colored candies, and a salt solution.

Experimentally Determine Avogadro's Number

Did you know that Avogadro's number isn't a mathematically derived unit? The number of particles in a mole of a material is determined experimentally. This easy method uses electrochemistry to make the determination.

Vitamin C Science Experiment
