Cosmo decided to study sound, and to get a better understanding, he calls EnergyFriend. He tells him that sound is energy made by vibrations. If an object vibrates, the air particles around it start to vibrate too, and this makes a sound wave. What if we make the loudest sound ever on Earth? What would happen to the people and the cities? Let’s start our simulation!

Cosmo is an animated robot from another planet that takes young viewers on a journey of scientific discovery. Each episode is curricula-based (grades 1 to 4), covering biology, structures and mechanisms, matter and energy, and Earth and space science. Cosmo is learning with the help of real kids that are the experts in each field. At the end of each video, Cosmo shares a fun exercise kids can demonstrate to their families using common objects found around the house.
