This science project explores the concept of being opaque or clear. Can you make something clear opaque? Or something opaque clear?

This science fair project idea explores how the shape of a boat affects its density and how much weight it can float.

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

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

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

This science fair project idea examines whether adding gelatin causes a solid to have a higher melting point and/or melt slower.

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

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

The purpose of this study is to determine if people can tell the difference between organic and conventional food from looking at, smelling and tasting it.

Make a backbone model to explore human anatomy and life science.

Test whether plants can grow without sunlight and water.

This science fair project teaches about mold. Students will test different foods to see which grow mold the fastest.

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

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

In this experiment we will be determining whether birds prefer certain colors of seed.

Will increasing the amount of salt in water effect how slow or fast the water freezes?

Determine if gender affects the ability to identify different smells.

This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

What is persistence of vision? With this hands-on science fair project idea, students will demonstrate this cool and dramatic phenomenon in their own classroom.

Cleaning can be a chore, but not with this sudsy experiment!

Spiders don't go to grocery stores or fast food chains to get their food -- they set up traps and wait for their food to come to them!

This science experiment tests whether warm or cold water works best in making cut flowers last longer.

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

This science fair project idea examines the reason boats are shaped and engineered.

This science fair project idea investigates the hardness property of minerals.

Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

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