Atmospheric Pressure!

My 3rd - 5th grade students can learn about atmospheric pressure through experimentation and the utilization of video technology.

Objectives: Students should be able to define low pressure, high pressure, and Bernoulli’s principle and be able to experiment with atmospheric pressure as a result of knowing the definition of the terms. Ultimately, students should apply their understanding and think of everyday applications for atmospheric pressure.

What happened to the balloons? Can you explain the reactions in terms of pressure?

Blow a steady stream of air between the two balloons. Try it with more or less space between the balloons!

Hold one string in each hand, so that the balloons are hanging downward, without touching!

Step 3: Hold

Step 4: Blow

Step 5: Record

Cut two equal length pieces of string about 2' long, then tie one string onto each balloon.

Inflate two balloons to relatively the same size; you can have fun with this by drawing faces or pictures on the balloons!

Step 1: Inflate

Step 2: Tie

See it!

Materials: Balloons (2) String (4')Markers

Student assessment can be measured by participation and written responses in step 5 of the experiment.

After this lesson, my students should begin to understand the effects of atmospheric pressure.
