Science fairs encourage schoolchildren to explore ideas and theories related to science. A science project can range from simple to complex, so it is important to find a project that is appropriate for the age group. Middle school science projects should not be simple, but they also should not be as complex as a project undertaken by a high school student.

Egg Projects

A variety of science projects can be performed with a couple of eggs and a few simple materials. For example, students can ask the questions: Does an egg sink or float? Can you change this? Add sugar or salt to the water, and see if the egg sinks or floats. Or, try building a container that will prevent an egg from breaking when it is dropped from a set height.

Flammability of Household Materials

How fast do you think various household materials will burn? You might be surprised. This project should be supervised by an adult. Gather a variety of materials such as:

  • lace
  • cotton
  • nylon
  • linen
  • rayon
  • denim

The materials must be the same size to provide accurate results. Place the material in a fireproof container, such as a metal pan or bowl. Determine which burn faster and which are more fire-resistant.

The Effect of Sports Drinks vs. Water on Pulse Rates

This science project studies how sports drinks and water affect a person’s pulse rate after exercise. You need a few willing participants, and you must know how to check someone’s pulse. Have half the participants drink a sports drink, and give the other half of the participants water. Check their pulse before and after they perform the same exercises for the same amount of time. Record and study the results to determine how pulse rates are affected.
