These experiments use materials you either have at home or else should be able to find easily. Bubble Life Versus Temperature Experiment A soap bubble consists of a thin layer of water trapped between two layers of soap molecules. brokenchopstick, Flickr 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 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. More » Caffeine & Typing Speed Experiment Caffeine (trimethylxanthine coffeine theine mateine guaranine methyltheobromine) is a stimulant drug and mild diuretic. In pure form, caffeine is a white crystalline solid. Icey, Wikipedia Commons 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. More » Baggie Chemistry Experiments Kids age 5-7 wearing safety goggles. Ryan McVay, Getty Images 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. More » Identify an Unknown You can do safe science in the comfort of your own kitchen. D. Anschutz, Getty Images This is a simple set of experiments kids (or anyone) can perform to learn about the scientific method and identify an unknown common household chemical. More » Fruit Ripening vs Ethylene Experiment Fruit. Emmi, EmmiP, morguefile.com Measure fruit ripening as the fruit is exposed to ethylene. The ethylene comes from a banana, so you don't need to order special chemicals. More » Explore the Chemistry of Pennies If you dip pennies in a solution of vinegar and salt and then let the pennies dry, they will be coated with verdigris in about an hour. Anne Helmenstine Use pennies, nails, and a few simple household ingredients to explore some of the properties of metals. More » Make a Polymer Ball Polymer balls can be quite beautiful. Anne Helmenstine Make a polymer ball and then play with the ratios of the ingredients to change the properties of the ball. More » Candy Chromatography Experiment You can use a coffee filter and a 1% salt solution to perform paper chromatography to separate pigments such as food colorings. Anne Helmenstine Analyze the dyes used in your favorite candies with paper chromatography using a coffee filter, colored candies, and a salt solution. More » Experimentally Determine Avogadro's Number Avogradro. 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. More » Vitamin C Science Experiment Citrus Fruit Varieties. Scott Bauer, USDA Use this redox-based iodometric titration to determine the amount of Vitamin C or ascorbic acid in juice and other samples.
