Create Your Own Barometer Science Lab

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

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

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

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

Step #4: What will we do? 1. Cut the blowing part off the balloon. 2. Tightly cover the jar with the balloon using a rubber band. 3. Place the straw horizontally or sideways on the plastic wrap so that two-thirds of the straw is on the can. 4. Tape the straw to the middle of the plastic wrap. 5. Get a piece of construction paper and create your reader. (I’ll show a video to help with this. ) 6. Record the location of the straw on the index card with a pencil. 7. After 15 minutes, record the new location of the straw on the index card.

Step #5: Data • 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.

Step #6 So what do you think? • Using complete sentences and descriptive words – Make a claim (What happened? ) – Give evidence (What observations support your claim? ) – Provide reasoning (Why does this happen? ) • What is a barometer? What does it measure? • How does a barometer work?
