Learned about air pressure, the atmosphere the, higher you go colder it get, layers of the atmosphere – troposphere, stratosphere, thermosphere, mesosphere.
Read books about balloons- hot air balloons, helium balloons and dirigibles.
Experiment were we crushed a can with air pressure.
The balloon was filled with gas. We were taking pitchers . I was taking pitchers on my phone. The balloon went up high. The balloon is going 97 mph. Know it is going 48 mph. Know it is going 19 mph. Know it is going 45mph know it is going 14 mph know it is going 16 mph. Know it is going 14 mph
The balloon launch was all ready to go the scientists filled up the balloon with hydrogen they told us that the hydrogen could blow up. 4th graders and 5th graders went out side to watch the launch. We counted down from ten. So when they let go it went up so high. It was so cool because it went from small to big. The fastest it went was 97 mph. The slowest it went was 1 mph. I wish we could do this every day. It pops at 107,096.
This how high our balloon when!
