Easy Science Fair Topics for Ninth Graders

There are several easy science fair projects ninth graders can create. They are easy because they require little time and resources and the results are immediate. In addition, by the time students reach the ninth grade, they should have already mastered basic science concepts about temperature, states of matter and physical and chemical changes. These easy projects still meet the requirements of the scientific method.
  1. How Temperature Affects the Elasticity of Rubber

    • This projects requires the student to test the elasticity of a rubber band at different temperatures. The easiest way to test this property is by subjecting a rubber band to cold temperatures in a freezer, at room temperature and hot temperatures regulated by an oven. Once a student tests the rubber band with a temperature, the student should try to stretch the rubber band and measure the length it stretches. The student should do this for each temperature and compare results. Once the results are recorded, the student will be able to determine whether a specific temperature increases the rubber band's elasticity or decreases it.

    How Temperature Affects Adhesive Glue

    • This easy project only requires the student to subject a vial of adhesive glue to different temperatures, ranging from cold to hot. After the vial of glue is tested with a specific temperature, the student should test the glue's adhesiveness. Once the observations are recorded, the student can determine how temperature affects the adhesiveness of glue.

    Liquid with the Greatest Level of Viscosity

    • This project is easy because it measures the viscosity or resistance of a liquid to flow. A student can choose any liquids to test. The student pours the liquid on a board at an incline of 45 degrees and measure how far the liquid flows. The student tests all the other liquids at the same incline and records the measurements. Once the data is recorded, the student will be able to determine which liquid has the greatest level of viscosity.

    The Effect of Temperature on the Rate of Dissolving

    • This easy project requires the student to take a substance such as a sugar cube and measure the rate at which it dissolves in water in different temperatures. Once the student records the rate of dissolving based on the different temperatures, the student can determine how temperature increases or decreases the rate of the sugar dissolving.
