It’s cold and wet outside- no good sledding today :( But we can still have fun with science inside! If you have a balloon and some common kitchen ingredients and utensils, you can do some chemistry magic following this 3M Science at Home video!

Have you ever turned the music up so loud that you can feel it? The floor seems to hum, and you can feel the vibrations in the walls and other objects in the room. How can music travel from a speakers and cause such powerful vibrations in other objects? In this activity you will make a model of your eardrum, and watch how sounds can make it vibrate! You will explore how sound creates vibrations and how that will affect small objects, from as little as a humming sound, to as loud of playing music through a speaker.

This chemistry experiment uses an acid, vinegar, and, a base, salt, in one bowl to clean copper pennies, and in another bowl, just vinegar to turn a penny green! When dirty pennies are placed in vinegar and salt, the copper oxide on and some of the copper on the penny dissolve in the water and is removed from the pennies surface. When the penny is rinsed off and wiped clean, it looks brand new! When a penny is soaked in just vinegar, it speeds up the process of oxidation and over a few hours the penny will be greener.
