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

Be Seen After Dark—What Clothes Keep You Safe?

Science Fair Project Idea

Scientific Method

Did you know that the most likely time to be struck and killed by a car in the United States is at dusk, dawn, or at night? In 2014, 3 out of every 4 pedestrian fatalities happened in these types of poor light conditions. Is there something you could do to decrease the chances you, your friends, and your family members are safer when walking or biking at night? Do you think the types of clothes that you wear could make a difference in how visible you are to drivers? Explore the science of… Read more

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
