David Webb

So yesterday in chem, we had a guest speaker come to our class to talk to us about gases and vacuums. At first, i thought it would be really boring and i was not looking forward to it. However, during lunch, my friend told me that last year, the people in olson's class thought that David Webb was really interesting and that he wasn't boring at all. When i got to chem class, i found that all the desks were moved so that they were all facing the lab tables. Then i noticed that two of the lab tables were full of small little things. While David Webb was teaching us about all the different things that vacuums and gases do, he also demonstrated it through various experiments. I thought that this was a really good way to teach because i have to see the experiment in order to learn it.

There was this one experiment where there were two metal half circles. After he put the two circles into the vacuum, they were shut tightly together. Then Mr. Olson showed us a picture of a lot of horses pulling on that circle. I think that means that it takes a lot of power to get those two half circle things separated.

I had to leave early for a badminton game but later on, my friend told me that i missed a marshmellow experiment ;(
