Earth is a planet full of water. 70% of its surface is covered with water in oceans, lakes, rivers, and more. Water on our planet can also be found in the atmosphere and underground. In this lesson, students will explore how water is continually cycled among land, the oceans, and the atmosphere. As students build a physical model of the water cycle, they will be able to simulate and observe evaporation, condensation, precipitation, and other water cycle processes in real-time. Remote… Read more

NGSS Performance Expectations:

MS-ESS2-4. Develop a model to describe the cycling of water through Earth's systems driven by energy from the sun and the force of gravity.

You might know that sound is caused by vibrations, but did you know that sound can also make things vibrate? You might have noticed this if you have ever been at a concert or in a car with the stereo booming. Sometimes the sounds are so loud that you can feel the vibrations! However, sounds that loud can damage your hearing, so in this project you will investigate them using something safer. Read more

Did you ever wonder what hand sanitizer is made of, or how you can efficiently disinfect your hands or other frequently touched surfaces like doorknobs? Handwashing is still the best way to keep your hands clean, but hand sanitizer is a great alternative for situations where clean water and soap are not available, and you can even use it to disinfect surfaces! Intrigued—try out making a hand sanitizer yourself! Read more

Make Your Own Shampoo and Test How It Performs!

Science Fair Project Idea

Scientific Method

Do you love it when your hair is nice and fresh? The key to keeping your hair nice and clean is to use a good shampoo. But with so many different products in the store, how do you know which one works best for you? In this science project, you will put a variety of shampoos to the test, including your own homemade organic shampoo recipes. Do you think these will perform better than a store-bought product?

Manipulating Magnets to Improve Generator Output

Science Fair Project Idea

Scientific Method

The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Marble Machine

Science Fair Project Idea

Engineering Design Process

Put your engineering skills to the test to see if you can build a machine—powered by nothing but gravity—that will automatically sort out two different sizes of plastic spheres. That might seem like a strange task, but have you ever used a coin sorter to separate pennies, nickels, dimes, and quarters? How about using a sifter in the kitchen to separate fine grains of flour or sugar from bigger lumps? Machines that can automatically sort objects or particles of different sizes are… Read more

Have you ever been zapped by a door knob or another person? It feels like a little electric shock and usually happens on cold and dry winter days. Where is this shock coming from? Why is it that sometimes you get zapped and sometimes you don't? It all has to do with static electricity, which can build up in some materials and then be transferred from one object to another. Sometimes you can even see a spark fly between them! In this science activity you will explore how well materials around… Read more

Measure the Frequency Response of a Paper Speaker

Science Fair Project Idea

Scientific Method

Can you build a working speaker out of paper? How does a speaker's ability to play low or high-pitched notes depend on its size? Explore the science of sound in this project as you build and test your own speakers in order to answer these questions! Read more

Measuring Antimicrobial Effectiveness with Zones of Inhibition

Science Fair Project Idea

Scientific Method

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate. Read more
