Air Pressure is a very abstract concept. It is essential in understanding of weather, but it is difficult to observe.
This investigation makes the abstract concrete in a mind-blowing mystery kind of way! This packet will walk you through the steps of constructing the water jug used for demonstration. It includes a materials list, detailed lesson plan,science explanation, lab sheet, answer key and photos.
This investigation is seriously one of my favorites to teach. Students have the opportunity to think critically and collaborate to solve the mystery of what causes nearly 2 liters of water to come pouring out of what seems like an ordinary soda bottle, when the teacher only poured in about a cup. It is thrilling to see what they come up with!
The "magic" is in the construction inside of the jug. A piece of tubing causes a Siphon Effect that empties the pre-filled bottle. This is all caused by air pressure!
This investigation will truly cause your students to be air pressure lovin' GEEKS: Genuinely Eager and Enthusiastic Kids at School!
