Cory and Shawn present their report on air pollution, in which they contend that the air density affects the performance of baseball teams during home games. This is because the air density affects the speed at which the ball travels through the air. They use the Colorado Rockies and the Philadelphia Phillies as examples: The Rockies average four more home runs per game because Colorado's air is much cleaner than Philadelphia's.
The CyberSquad has available different-sized air tanks to travel to Crab Kingdom. The higher the capacity of the tank, the slower the bike. They try to estimate which tank size will be enough for the round trip to Crab Kingdom. Matt takes the six-minute tank to check how long it takes to travel to their first destination, which he verifies to be six minutes. While they can take the 18-minute tanks, they estimate high to be safe and decide to take the 24-minute tanks.
Harry helps kids to come up with ways to show that air is everywhere. The kids learn that air's all around them. The first way to prove is that creature needs air to breathe and make their bodies work. The second is that smell travels through the air. The third is that when something is falling to the ground, it pushes air out of the way so it can get to the ground, so the air being there is the reason it floats. The fourth is that when people blow air into a bottle it makes music.
Victor Hess tests his own hypothesis of cosmic radiation by using a hot air balloon and checking the radiation in the atmosphere. He noticed that it did indeed increase as he traveled higher up in the air.
