Pssssshhhhhhh! Watch out! Air is on the loose! Did you know air is powerful? Well we do, because we've studied air in science. When you compress air, it makes a force called air pressure. In science centers, we did five experiments about air and air pressure. At one of the centers, we launched balloon rockets! We had a bag on a string, and we had to pump up a balloon to make it go. At another center, we pumped up balls with different amounts of air to see which one bounced better. The more pumps we put in, the higher the ball bounced, AND the faster the balloon rocket went. That's air pressure!
This blog is maintained as a collaboration between all students and myself. Each week, one student has the classroom job of "Blogger". That student helps decide subjects for our posts, as well as writing one blog post about him/herself.
