Balloon in a Bottle
Balloon in a Bottle
You will need: A balloon, two glass tubes, rubber
band, bottle or large jar and cork.
Secure a balloon to the end of a glass tube with
a rubber band, as illustrated.
Now take a bottle or large
jar with a tight-fitting cork. Drill two holes through the cork and insert the
tubes (A and B).
A smear of butter on each
length of tubing will assist their entry into the cork and also ensure an
airtight fit. Another smear of butter around the cork will similarly ensure an
airtight fit in the mouth of the jar.
Children learn best through doing
Before children can
understand a thing, they need experience: seeing, touching, hearing, tasting,
smelling; choosing, arranging, putting things together, taking things apart.
Experimenting with real things.
Old-time school teaching
used only words and the teachers thought children knew something if they could
repeat it. Now we know better. To reach practical understanding we do not need
to use many words with young children.
Children are
clever. They learn a lot, without being taught. The greatest skill - to be able
to talk, to communicate is learnt outside school. In the classroom it's the
children who need to talk the most. Unfortunately it is the teacher who does
most of the talking!
