Students will use the bell jar and vacuum pump to explore the properties of different object in a vacuum. Can you hear your phone without air? What happens to a balloon in a vacuum? Does water boil in a vacuum? How do shaving cream and marshmallows react in a vacuum?

By observing how different materials behave without atmospheric pressure students can identify the affects of atmospheric pressure. Additionally students will investigate sound as a mechanical wave.
