You will need: Soda, test tube, tongs, candle.
Water is present in varying
degrees in many apparently solid substances. Our own bodies consist of a very
high percentage of water. Even such substances as ordinary washing soda (or
sodium carbonate, to give it its correct chemical name) contain a large
proportion of water. This can be verified by a simple experiment.
Take a spoonful of soda and drop it into the
bottom of a test tube.
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!
