In Science we are learning about air and weather. We have put a tube on a syringe. We pushed a plunger into the syringe and were able to blow a feather with it. The plunger pushed air out of the syringe. Then we tried to pull the feather into the tube by pulling the plunger back out. We also put two syringes together by connecting them with a tube. When we pushed one plunger in, the other came out, like a teeter-totter. We even tried pushing one plunger very hard and it popped the other end out. It all happened because of air compression. Air takes up space and when it is being pushed, it needs a place to go. If it is pushed too hard, it will push back.
Another air experiment we did was making parachutes. We laid out a tissue and unfolded it. We had 4 pieces of string and taped them onto the corners of the tissue. Then we put them together and used a paper clip to tie the strings together. The paper clip was weight so the parachute could go down, like a person wearing a parachute. As it falls, air gets captured and pushes against the tissue, making it go down slow. We really enjoyed using them! We experimented with taking layers off the parachutes to see how it changes the way it falls. It fell slower. We took them outside and tested them on the play set. You can see a picture of this below! That's what we are doing in Science!

1. Tell us if you have ever jumped out of a plane and what it felt like to fall with a parachute.
2. What are some other experiments we could try with air?
