Topic: Air Pressure
Time Duration: 1 hour and 30 minutes
Grades: K to 4th grade
The students explored air pressure using balloons. The instructor conducted two experiments
for the students. The first experiment was blowing up a balloon using different water
temperatures. A glass bowl was filled with ice cold water and a glass bottle was filled with
hot water. The balloon was placed over the neck of the bottle and pushed down into the
bottle. The glass bottle was placed inside of the bowl and the balloon was slowly blown up
by the different air pressures. The next experiment was called "Rocket Balloons". The
students were grouped into teams of three or four and each group tried to launch the balloon
across a string to the other team members. The class was able to explore how air pressure
occurs and what it does.
