Blowing in the Wind Experiment
How we did it:
- petroleum jelly
Punch a hole in the card and tie onto a tree branch or gate with the twine. We decided to hang three cards to see if we got different results in different locations.
Smear the petroleum jelly over one side of the card, and leave out in the wind. If you like, make a prediction of how much you think you'll catch in each location.
Return in an hour or two and see what was blowing in the wind! Write up a chart and use it to help compare what you predicted with what actually happened. Writing down predictions is always a good lead-in to discussions about the things you got wrong and why!
