Today I witnessed something that makes so much sense, but never before occurred to me. In our Science class we were instructed to undertake a number of science activities, this balloon hovercraft activity (see picture above) being one of them.
We had a CD, that had the top of a drink bottle tightly glued to it, and what we did was blow up a balloon, and place the inflated balloon over the top of the drink bottle, then turn the lid into open position and release the balloon, TA DA! we have a balloon hovercraft.
We have spent a bit of time in class now learning about matter, one of the questions in this activity was, what are 5 things we know about gases, and this is what we have found:
- You can not see it
- It has no shape
- It takes up the volume of its container
- It vibrates quickly and the particles move past each other
- Gas can be transformed into a liquid(condensation), formed from a liquid (evaporation), and turned into a solid (sublimation) and formed from a
solid (deposition)
If watching a balloon hovercraft was this exciting for me, imagine how exciting it will be for my kids, and the kids in my future centre!
