Students will love seeing the water balloon get sucked into the jar! The FREE resource allows you to see a sample of my work. This resource is a science experiment on air pressure. It comes with directions, discussion questions, a lab sheet, a lab followup sheet, a short nonfiction article on air pressure and a vocabulary flap for interactive notebooks. All you need for the experiment is a glass jar, water, balloon, paper and a match. This is a REALLY low prep demonstration and it is fun and dramatic to watch.
Please leave feedback after downloading this free resource!
This sample is from some of my larger units on air pressure, air masses and weather. If you are interested in getting the whole unit please see
