Thing #18

A number of our teachers are using videos both from teacher tube and utube. At this time utube has more cool science videos than teacher tube but i think that will change over time. 

Utube has much more junk on it so you have to be careful what you use. I wold be real careful sending students to a utube web site but I would use it in class and embedded on my own web site.

Fore science teachers it allows us to show demons that we may not have time, money or equipment to to in our class. 

• This is a Utube science video called How much Sugar is in a can of Soda.

• This is a teacher tube called Thunder and Lightening 

• This is the most amazing video. This is a Ping-Pong ball launched by what is called a vacuum cannon. It is a 10 foot long PVC Pipe with aluminum foil covering each end and a ping-pong ball in side. A vacuum is drawn on the tube so it is a vacuum inside. then you poke one end with a sharp object. Air rushes in and accelerates the ball so fast it comes out the other end with enough force to destroy a coke can.
