Experiments to do at
Materials: Clear drinking
glass, a piece of paper or tissue, and a bucket.
NOTE: The bucket must
be taller than the glass and the paper must fit half way up the drinking
Experiment: Fill the
bucket between halfway and 3 quarters of the way
Make the paper into a ball and put
it in the bottom of the drinking glass.
Turn the glass upside down. The paper
ball must stay in the bottom of the glass. If it falls out make the paper
Hold the glass upside down and put
it in the bucket that has water in it. Make sure the glass touches the
bottom of the bucket.
Pull the glass up but DO NOT TILT the
glass as you pull it up.
Examine the paper. It should be dry
(if you did it right).
Why: The glass is filled
with paper and air. The air prevents the water from going into the glass
keeping the paper dry.
Materials: cola bottle
or any other small mouthed bottle, and a balloon
NOTE: The balloon mouth must fit over
the bottle mouth.

Experiment:Hold on to
the top of the bottle and push the balloon inside the bottle.
Stretch the top (or part you blow in
to) over the mouth of the bottle.
Try to inflate the balloon.
The balloon only expands slightly (if
you did it right).
Why: The bottle is filled
with air molecules. Blowing in to the balloon makes the air molecules go
closer together. Making the balloon inflate only a little.
