M&M Math: Weekly Science Project Idea/Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of projects that put statistics in the palm of your hands. In these hands-on math projects and activities, students investigate to find out how often each color of M&M appears in a bag or group of bags. Have a guess as to which color appears most often? Put your guess to the test! What is the likelihood of pulling a yellow M&M from a brand new bag? After this activity, your student will be able to give you the odds—with some statistics to back them up!… Read more

Modeling the Human Cardiovascular System: The Factors That Affect Blood Flow Rate

Science Fair Project Idea

Scientific Method

People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… Read more

Music for Martians: Build and Play a Theremin Instrument

Science Fair Project Idea

Scientific Method

Here is a riddle for you: name an instrument that you play with your hands but never actually touch. Have you guessed the answer? It is a theremin! This unusual instrument makes sound without anyone touching it. How does a theremin work? It has an antenna that can detect the player's hand nearby, and as they move their hand around the theremin, the sound it makes changes based on the hand's position. In this music science project, you will get to use your own mini theremin to investigate how… 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

Musical Straws: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a music-themed family science experiment and science fair project. With a set of ordinary drinking straws, you can create a group straw "oboes." Can you play them? Sure! By blowing air through them, similar to the way you play a reed instrument, you can produce musical notes. At the end of the activity, you should have a set of straws, each of which will play a different note on a musical scale. What is the secret to changing the note each one plays? In this music… Read more

It’s happened to most of us; you wear a brand new shirt to school or work, and in the middle of lunch, get a giant ketchup stain right in the middle of the shirt. Or maybe peanut butter. Or maybe spaghetti sauce. Whatever the stain is, it’s always ugly, and can be tricky to remove. Did you know that there are many different kinds of stains, and each requires different types of cleaning to get the stain out? If you try to clean a mustard stain using shower cleaner – you… Read more
