Mixing Your Own Marshmallows: Finding the Right Ratio of Sugar to Corn Syrup

Science Fair Project Idea

Scientific Method

Whether you are sitting around a campfire, or drinking hot chocolate after a day in the snow, nothing says fun quite like a marshmallow! Even its name is soft and spongy! In this cooking and food science fair project, you will make your own marshmallows several different ways, and discover the three special ingredients that give marshmallows their unique texture. You will also find out why they melt so quickly. Explore the science of these sticky, spongy sweets! Read more

Have you ever blown across a bottle's top and made a pleasant, resonant sound? If so, have you wondered how that note is made exactly? The exact note you hear depends on the resonant frequency of the air in the bottle. Musical instruments like ocarinas operate based on a similar principle. In this science activity, you will use bottles to investigate how the volume of the air in the bottle affects the pitch of the note that it makes. Read more

Put Your Water to Work: Using Hydropower to Lift a Load

Science Fair Project Idea

Scientific Method

Earth is an amazing planet. It has everything that we need: food, shelter, and water. Sure, we need water to drink, but have you thought about using water to create energy? Moving water has a lot of energy and all we need to do is to harness it. Moving water made the Grand Canyon. That took a lot of energy! In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight. Read more

Rubber Band Elasticity and Temperature

Science Fair Project Idea

Scientific Method

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures? Read more

Rubbing Up Against Static Electricity

Science Fair Project Idea

Scientific Method

A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. How does the rubbing build up static electricity? Do this experiment to see if the number of rubs makes a difference. Read more

Shaking for Butter

Science Fair Project Idea

Scientific Method

Hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, hot flaky potatoes with melted butter. Yum! It seems like everything tastes better when you add butter. But what is butter and how is it made? In this food science fair project, you will find out, and you will test different conditions for making butter and determine the best method. Read more

Forces, which we might instinctively describe as pushes and pulls, are acting on us at all times, but we cannot always see them. This hands-on lesson offers a fun opportunity to explore "invisible" forces like gravity and air resistance. Students will build parachutes and investigate how they allow skydivers to safely land.

NGSS Performance Expectations:

3-PS2-1. Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

Solar-powered Chemistry: Study Chemical Reaction Rates in Ultraviolet Beads

Science Fair Project Idea

Scientific Method

Most of the ultraviolet (UV) light produced by the Sun is blocked by the atmosphere, but some UV light does still reach Earth. It can be detected using electronic devices, but can also be detected with something called UV beads. UV beads contain a pigment that changes color when they are exposed to ultraviolet radiation from the Sun. In this chemistry science fair project, you will use UV beads to study how temperature affects the rate at which they lose their color. Read more
