A Windy Experiment

MATERIALS NEEDED:
  • marble
  • small blown up balloon
  • plastic egg
  • feather
  • small ball
  • a recording sheet (optional)
*Note*  You can use any small items you want.  These items are just what we used.

OTHER ITEMS TO CONSIDER...
  • block
  • hot wheel car
  • lego
  • leaf
  • cotton ball
  • pencil
  • barbie shoe
  • plastic animal
  • etc.
PROCEDURES:

1. First, predict if an item could be blown away by the wind (a child blowing through a straw).

2. Then, use a straw and blow air at each object. We wanted the objects to at least get half way across the table to be considered a "YES".

3. Finally, recored your observations as a yes or no.  Discuss why the wind did or did not "blow" an object.

FOLLOW UP ACTIVITY...
Go outside on a windy day.  Take your learning or nature journal outside with you.  Record or draw pictures of items that you observe teh wind blowing.  As always, discuss the reasons why the wind was able to blow the object.

BONUS FUN...
Use a straw to blow the balloon around on a table top.  Each person should try to keep the balloon on the table. For a challenge, try not to get touched by the balloon during the game.
