Right now in science we are learning about sound. So far we have experimented with different kinds of vibrations using balloons, paper squawkers and our own vocal cords. We have also learned how we hear sounds with our ears by making a booklet and acting out the parts of the ear. Today we used Slinkies to model sound waves. I will post photos of our activities later in the week, but for now, here are three short videos about sound for you to watch. What is the most important thing you know about sound?
