How do crystals form? In this science fair project, students will use three different saturated solutions to see how different minerals form crystals over time.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

Science fair project idea that examines different physical characteristics of a chosen animal. Make educated guesses about evolution based on animal's form.

How do icicles form and what do they look like? Do this free science fair project and watch the formation of icicles occur right before your eyes.

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

How does rust form? Kids will learn about the roles oxygen, water, and electrons play in rust chemistry in this cool science fair project idea.

In this science fair project, students will use four different household objects to see which ones form the most or best crystals.

This science fair project idea demonstrates that plants give off water.

This science fair project idea explores how water and ice can change the form of rocks.

In this cool science project, model how impact craters form on the surface of the moon.

Science fair project that examines how winter storms form and the relationship between temperature, moisture and snow.

Learn how different types of soil affect how animal tracks form in this experiment!

This science fair project idea explores if male or female humans are more likely to exhibit some form of color blindness.

Science fair project that examines condensation and the conditions needed in order for dew to form.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

Learn the basic structure of a DNA strand, which is the double helix, how genes form together, and the resemblance DNA has to a twisted ladder. Create a model.

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

It's not actually that hard to get energy from garbage! Kids learn how to make biogas in the form of methane with this cool and easy science fair project idea.

What does yeast eat? Sugar, of course. But yeast also has some powerful enemies in the form of antifungal agents! Kids test them out in this fun yeast lab.

The purpose of this science fair project is to investigate whether we can simulate how craters are formed and predict their size and shape.

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

Science fair project that demonstrates how stalagmites and stalactites are formed.

Science fair project that demonstrates how a rainbow forms, by using water to split white light into its many colors.

In this experiment, you experiment with laser jet toner, a magnetic fluid, as it moves, bubbles, and forms unique shapes.

Science fair project in which you will examine how crystals are formed by creating your own crystal using charcoal briquettes, salt, and ammonia.

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

Determine how salinity affects the circulation of warm and cold water. Note whether the warm water mixes or forms a layer with cold water.

Science fair project that demonstrate how abrasions are formed on rocks in nature and the variations between types of rocks.
