The purpose of this experiment is to allow the children to observe how balls float when the blow dryer is on. The blow dryer is turned on to the highest level and then the balls are placed over it. The air pressure from the blow dryer allows the ball to float. This experiment was such fun for the children. They continuously request this activity on science days.
Things needed:
- Blow dryer with at least 2 settings – low and high
- Lightweight balls like the ones found in a bounce house or golf balls (I used the light weight balls)
- Lots of little people
Before we began our exercise we asked the children to throw the balls up and watch what happened. We have been talking about gravity – what goes up must come down. Although this experiment contradicts what goes up comes down, I wanted the children to get an understanding of some other principles of science. After much playing of catch the ball we finally got to the science experiment started. Since that day a ball with a blow dryer together has not been the same.
Instructions
- Plug in blow dryer of course (adults only – never ask children to mess with electricity).
- Place on highest setting
- Add a ball above the blow dryer and …voilà! (best is using a lightweight small ball..the size of a golf ball is ok)
- For drama and fun which our little people like …add one or two more balls, and see what happens
Allow each child to take a turn
Teacher demonstration – you can see how anxiuos they are to try this.
Each child got a chance with the ball ( …oh except one that was afraid of the blow dryers sound)
Science is so much fun! It is never too early to introduce science to very young children. In my opinion there is no need to be detailed about the varying air pressures that cause the ballon to float. I would rather have them experiment more than be overwhelmed with logic. This early introduction will set the stage for more indepth work and acquired knowledge when they are older.
