Have you ever poured sand out of a bucket, or poured cereal out of a box, and noticed it is a lot like pouring water? It is because sand and cereal are granular materials. This means they are made up of solid particles, but they can actually flow like liquids! Candies, like Skittles®, M&M's®, Nerds® candies and many others, are also granular materials. In this science activity, you will investigate how the size and shape of granular materials affect how they flow. And what… Read more

Do you feel like it is always too loud in your classroom? In this lesson you can find out exactly how loud it is. Using a mobile phone and a sensor app, your students will measure and graph the sound levels in your classroom for different working scenarios. How loud are your students when doing independent work, having a group discussion, or listening to their teacher? Based on your students' data, you will determine as a class which sound levels are ideal for each scenario and create a… Read more

NGSS Performance Expectations:

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Come One, Come All! Explore the Effect of Light on the Speed of the Amazing Rotating Radiometer!

Science Fair Project Idea

Scientific Method

Radiometers are fun-to-watch novelty items, but they also have a distinguished scientific history, having been studied by James Clerk Maxwell and Albert Einstein. A radiometer has a set of four vanes (like small sails) connected to a spindle that is free to rotate. When the radiometer is placed in bright light, the vanes and spindle start to spin. It looks like a magic trick, but there is a scientific explanation for this weird behavior. In this science fair project, you will experiment with… Read more

Distance and Speed of Rolling Objects Measured from Video Recordings

Science Fair Project Idea

Scientific Method

This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. Sure, it's been done before, but if you do it yourself, you can get a firm understanding of these important concepts. Read more

How Does Your Eardrum Work?

Science Fair Project Idea

Scientific Method

Eardrums are membranes inside your ears that vibrate when sound waves hit them. These vibrations are converted into electrical signals and sent to your brain, which allows you to hear sound. The frequency response of your eardrum, or the range of frequencies that will cause it to vibrate, determines your hearing range. Typical human hearing ranges from about 20 Hz up to 20,000 Hz, although the ability to hear high frequencies typically degrades as you get older. Some other animals can… Read more

How Long Will My Sleepy Yo-yo Sleep?

Science Fair Project Idea

Scientific Method

Sometimes, simple toys can be quite complicated. Take the yo-yo. It's a fun toy and there is nothing simpler than a string wrapped between two connected disks. But there's a lot of physics that makes a yo-yo work. In this science fair project, learn more about how and why a yo-yo works. You will investigate the effect of string length on the yo-yo's "sleep" trick time. If people ask why you've got a yo-yo with you all the time, tell them that while it looks like you're just having fun, you're… Read more

Are you any good at hula hooping? If not, there is good news: you can do this fun project without any hula hooping experience! You will examine some of the fascinating physics behind hula hooping using just a pencil and a rubber band. Read more

Investigate the 'Death' of an Orange: How is Rate of Heat Loss Based on the Surrounding Temperature?

Science Fair Project Idea

Scientific Method

Imagine that you are a detective investigating a murder. You have a body that was found in a swimming pool, and someone reported hearing an argument near the pool at 10:00 PM the night before. Your first question might be "Was this person killed around 10:00 PM last night, or at some other time?" One way to answer this question is to measure the internal temperature of the body. The longer ago the killing occurred, the colder the body. But can you assign a specific time of death to a specific… Read more
