Air Pressure

Lots of demonstrations today!  We will conduct as many demonstrations as time and resources permit.  Students are encouraged to watch the videos below to make additional observations and to help explain what is happening in each of the demonstrations.  Students will write observations and draw pictures of air molecules to visualize pressure using the space provided on the Lesson 57 Worksheet.  The Lesson 57 PowerPoint includes the definition of pressure.
