Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

This science fair project idea explores whether boiling and freezing water will have an effect on how much it weighs.

This science fair project idea explores whether factors such as temperature and concentration affect the pH of a solution.

This experiment examines whether storing your orange juice at different temperatures affects its acidity.

Is horse manure a possible energy source in a crisis? Use calorimetry to find out how much energy horse manure can produce in this science fair project.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

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

Check out this cool science fair project idea to explore the risk of mechanical deterioration of artifacts placed in a storage box due to mold outbreaks.
