This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Measure the porosity of rocks by submerging them in water. Measure how much water each rock "drank," by measuring the difference in water volume.

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

The goal of this science fair project was to examine how different angles of decline affect the tipping point of a vehicle.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

This science fair project idea builds models of various types of bridges and then determines which bridge design is the strongest.

This science fair project idea demonstrates the process of land erosion.

This science fair project idea investigates how different disinfectants work in killing germs.

The purpose of this science project is to determine whether the amount of air in a soccer ball affects how far it goes when kicked.

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

Determine which material produces the strongest static charge.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

The buoyant force of water explains why some objects float in water. But why do some objects sink? Find out in this physics experiment and learn about density.

This science fair project idea focuses on saturated and unsaturated lipids (fats and oils).

Explore whether pianists have the tendency to type faster than non-pianists.

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?

There is debate about whether chalkboards or whiteboards are better. This experiment explores which leads to better retention of visually-displayed information.

This is a quick, easy science fair project that conveys the idea of density to upper elementary students.
