  1. Create Your Own Barometer Science Lab

  2. Explanation: • You will be creating a barometer to examine the change in pressure. • The balloon will react to changes in air pressure.

  3. Step #1: Problem • How will the balloon react to changes in air pressure?

  4. Step #2: Hypothesis • In your own words predict what you think the outcome of the experiment will be.

  5. Step #3: Materials • Glass Jar • Balloon • Scissors • A straw • A piece of construction paper • A rubber band • Scotch Tape

  6. Step #4: Procedures • Cut the blowing part off the balloon. • Tightly cover the jar with the balloon using a rubber band. • Place the straw horizontally or sideways on the plastic wrap so that two-thirds of the straw is on the can. • Tape the straw to the middle of the plastic wrap. • Get a piece of construction paper and create your reader. (I’ll show a video to help with this.) • Record the location of the straw on the index card with a pencil. • After 15 minutes, record the new location of the straw on the index card.

  7. Step #5: Results • After you have recorded the location of your straw several times, write the changes you saw and any observations that you made while conducting this experiment.

  8. Step #6 Conclusion • Using complete sentences and descriptive words answer the question you wrote for step #1.
