Have you ever wondered how crystals are made? Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this activity, you will compare the size and shape of crystals grown at different temperatures. With just water and Borax, a household cleaning product, you can discover the method for growing large, pure crystals! Read more

Measuring the Amount of Acid in Vinegar by Titration with an Indicator Solution

Science Fair Project Idea

Scientific Method

Have you ever wondered why some foods taste really sour? Vinegar is one example that you might know from salad dressings or pickles. They taste pretty sour, right? There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. Do you think all the different vinegars contain the same amount of acetic acid? Are there some that are more sour than others? How… Read more

When light interacts with an object, it can be absorbed, transmitted, or reflected. This lesson focuses on materials that reflect light. Specifically, students will use mirrors and flashlights to investigate how light is reflected from a surface. By doing that, they will discover that when a light ray hits a reflective surface, its angle of incidence is equal to the angle of reflection, which is stated by the law of reflection. Students will then use their gained knowledge in a mirror maze… Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
MS-ETS1-4. Develop a model to generate data for the iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Take a Candle Carousel for a Spin

Science Fair Project Idea

Scientific Method

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the… Read more

Water Quality

Science Fair Project Idea

Scientific Method

It is important to ensure that we all have good clean water to drink that is not contaminated by heavy metals or chemicals. One common pollutant in a water supply is lead in old pipes or paints that can leach into the water and cause lead poisoning. There are different kits available for testing the presence of lead and other contaminants in water. Test your water supply, and also the water in some local ponds, lakes or streams. The same contaminants that can harm you can also harm wildlife. … Read more

Which Orange Juice Has the Most Vitamin C?

Science Fair Project Idea

Scientific Method

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Your students will design, build, and race balloon-powered cars in this fun lesson plan that teaches about engineering design and kinetic and potential energy. Read more

NGSS Performance Expectations:

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from that object.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Different types of birds lay their eggs in different places. Some build tiny nests in bushes, some build enormous nests in tall trees. Some lay their eggs directly on the ground or on rocky ledges. Those that build nests use many different types of materials. In this project you will try to build your own bird nest using only natural materials that you can find outside. Can you do better than a bird? Read more

Have you ever had a sunburn? If so, you know how powerful the Sun's heat can be! Did you know that this heat can also be turned into electrical energy? You may have heard about solar cells, but what about a solar updraft tower? This very simple structure uses the sun to heat up air, which then powers a turbine within a large tower. In this activity, you will build one of these towers yourself. Do you think you can make a propeller spin with just hot air? Read more
