Science fair projects don't have to be complicated. The trick to creating a simple science fair project is choosing a project idea that uses easy-to-find materials and requires little time. The science projects listed below fit the bill. You can create most without any supplies or with common items you have in your house, garage, or classroom. The projects are sectioned by topic: Each one is topped by one or two questions and fully explained in two to four sentences.

 The Body and Senses

The human body is a great platform for creating easy science projects. The ability to breath, taste, smell and hear all are great starting points as the ideas in this section demonstrate.

  • Does age make a difference in lung capacity? Does gender? Does smoking versus nonsmoking? Have different people blow up a balloon as much as they can, measure the balloon to calculate the volume of air, and analyze the data.
  • Which sense is better at helping you identify food, taste or smell? Cube produce with a similar texture (or mash it), blindfold your test subject and ask him to identify the food based on how it smells. Switch the order of the foods and have your subject guess what each is according to how it tastes. Try this with different types of meat, too.
  • Does listening to music while taking a test affect performance? Does the type of music make a difference? Set this up by having your subject take tests of comparable difficulty with and without music or with different types of music playing.

Water and Other Liquids

Fizzy soft drinks make great props for simple science projects, as do milk, juice, oil, and even plain old water. 

  • Which carbonated soft drink stays fizzy the longest? Set your sodas on the counter and see how long they produce bubbles.
  • Which uses more water, a bath or a shower? Stop the drain, take a bath, and then take a shower. You can mark the tub if you want a simple more-less comparison or break out the measuring cup if you want to know exactly how much water you used.
  • Which liquids prevent seed germinations? Try sprouting seeds (uncooked beans from the grocery store will work) in various liquids, such as tap water, milk, cola, juice, or oil.

The Weather and Heat

The weather is always a sure bet for an easy science project, as is the concept of heat. All you need to perform the projects in this section are a thermometer, a barometer, and a common material.

  • Can you forecast the weather yourself? Don't listen to the weather report (but do recruit someone else to record the forecasts). Use simple instruments such as a thermometer and barometer and look at the sky to predict the weather. Compare your predictions with those made by the weather service.
  • Which color of a material heats the quickest and cools the quickest? Get different colors of the same type of material—leather or rocks, for example—and a thermometer. Which heats more quickly on a sunny day? Which cools more quickly? Or are they the same?
