Quick Science Experiments

With Ebi-kuns new school schedule we have very little after school time these days :(
So for the little time we have I want to fill it with fun activities to use his brain, ask more questions, expand his English...

Today's experiments were will balloons, quick an easy to set up...

You need:

  • 2 chairs
  • String
  • Balloons
  • Straw
  • Masking tape 

To set up, tie one end of the string to the back of a chair. Then the string through a straw. Tie the other end of the string to the other chair, pull the string so it is tight.

Next, blow up a balloon, don't tie the end, hold onto it! And using the masking tape, stick it to the straw (shown below)

Let go and see what happens...

Once you have done it a couple of times, try experimenting. 

  • What happens if you only tape the front of the balloon? How about just the back?
  • What happens if you tape two balloons facing the same direction, how about two balloons facing the opposite direction?
  • Why does the balloon move the way it does?
  • Would a different gas produce a different result?
  • What if the gas was warmer? Cooler?

Predict the results before you do each experiment.

What other experiments can you try?

I'm looking forward to more quick experiments, I foresee a jojoebi mini series coming on...
