This science fair project idea explores plant growth from a bulb, root, and a stem and investigates asexual plant reproduction.

This science fair project idea determines if crystals will absorb food dye and if colors will mix by the process of diffusion.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

In this science fair project, students create their own miniature salt flats at home.

This project determines what category of person is most likely to be ticklish.

This science fair project teaches students about wilting and browning of salad greens.

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

Throughout history, people have used song as a teaching and memory tool. This project explores whether song improves a person's ability to retain information.

This science fair project idea provides evidence that air is everywhere and takes up space.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

Science fair project idea which teaches you how to make butter by separating cream into butter and buttermilk.

This science fair project uses paper chromatography to investigate whether black, brown, orange, and purple are pure colors or mixtures of other colors.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

This science fair project idea explores whether the process used to dry the beans we eat for food renders them unviable.

Science fair project which tests various sedimentary, igneous and metamorphic rocks to find out whether one rock family is stronger than the others.

In this science fair project, students use the streak test to tell minerals apart from each other.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

Discover whether the â5-second ruleâ is effective at determining whether food is still safe to eat after being dropped on the ground.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

This science fair project examines how seeds hitchhike on animals and clothing.

This science fair project explores how osmotic pressure forces water through the root up into the plant.

Explore how dielectric heating comes into play when microwaving various liquids in this science project. This test will help you understand how microwaves work!

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

With this science fair idea, little scientists will gain valuable insights into the physics behind throwing a baseball.
