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

This science fair project idea identifies clouds as a means of predicting the weather.

Kids learn about examples of mechanical weathering and conduct an experiment with seeds and plaster in this cool geology science fair project idea.

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

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

This science fair project idea measures and compares effects of chemical weathering, specifically carbonation, on different kinds of rocks.

The project investigates how water and movement affects erosion.

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

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

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.

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

In this science fair project, learn how a mineral streak is made and how it can help identify an unknown mineral.

Did you even wonder why some rocks are round and smooth while others are broken up into small pieces?

The goal of this evaporation experiment is to learn about how different external conditions affect drying 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.

Gymnosperms are coniferous trees that reproduces using pine cones to spread seeds. Check out this simple pine cone experiment to learn about the process!

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

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

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.

Get this cool science fair idea to explore how arctic tundra animals change their behavior and adapt to survive in long, cold winters.

In this science fair project, students make their own rain gauge to measure rainfall.

What's the relationship between temperature, air humidity and static electricity? Kids will find out with this free static electricity science fair project.

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.

Enter the buzz worthy world of bee watching and find out what time bees like to wake up!

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.
