I think that air is a matter because we did the experiment before (not in H.I.S).
First we measured the weight of a balloon, then we filled it up with air. When we measured the weight again, we found out that there was a slight difference between the first measured and the second measured.

Hey Leo--
Great job blogging! Next time, if you use information from other sources (the internet), you should cite your sources. This means that you tell everybody what websites you used to find your information.
The website you used was:
http://education.jlab.org/qa/matter_03.html
So you should put that at the bottom of your post. It is okay to use other sources, we just have to make sure to give them credit. :)
Even better!
