Background Bop: Do Different Businesses Play Different Tempos in Background Music?

Science Fair Project Idea

Scientific Method

Walk into a fitness club and what kind of music do you hear? Slow, sparkling, relaxing music? Or driving, "up-tempo" songs that are designed to encourage you to move? Fitness clubs and other businesses, like restaurants and grocery stores, use background music to set the mood and to determine how fast they want their customers to move. The tempo of the background music is a key component to the environment that businesses want to create. Tempo is an important number or word inscribed by a… Read more

Bacteria Can Fix It! A Comparison of Nitrogen-Fixing Bacteria and Nitrogen Fertilizers

Science Fair Project Idea

Scientific Method

Do you know what plants need to grow? Sure, they need soil, water, and sunshine. Everyone knows that. But here's a secret: they also need nitrogen. Plants use nitrogen to make DNA in their cells and the proteins that lead to healthy stems and leaves. The problem is, although the Earth's atmosphere is made up of 78% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. So how do plants get their nitrogen? Either through nitrogen deposits in the soil, or through… Read more

What makes an object balanced? Look around you—most of the objects in the room are probably balanced and not on the verge of tipping over. If someone hands you an object and asks you to put it down, you probably know, without thinking about it too much, how to place it so it won't fall over. But what's the science behind how an object balances? Why do certain objects only balance on some sides and not others? Try this project to find out! Read more

Have you ever watched an old movie, or a cartoon, where a character holds a cone to their ear in order to hear what people are saying? Believe it or not, those cones (known as ear trumpets) were the very first hearing aids and were very popular for a time. Even Ludwig Van Beethoven used one! They helped people hear by acting as a sound amplifier, collecting sound waves and focusing their energy into the ear. In today’s activity you are going to make a different type of sound amplifier… Read more

Batteries: The Shocking Truth

Science Fair Project Idea

Scientific Method

You probably use batteries to power different devices every day, ranging from toys to TV remotes, without giving it much thought. Figure 1, below, shows some common types of batteries. Eventually the batteries will die and you have to replace them with new ones (or recharge them if they are rechargeable batteries). How much do you actually know about how batteries work? This abbreviated project idea will give you some suggestions to investigate how batteries perform in common household… Read more
