The teacher tells the children:
Today
our pet has told me that we have to be very careful with the food
we take and with the water we drink. If the water and the soil are
dirty or poisoned with polluting products, the animals and plants
that live in that area can also be contaminated and, as we eat them,
perhaps we can be poisoned and become ill, too.
Let's
make an experiment so that you can understand better what happens.
We
need:
- A
glass of water
- Some
watercolours or colouring matter
- A
branch of celery
Each child will drop some watercolour or colouring
into his/her glass of water. Then everybody will introduce the celery
into the water too. At the end of he day we will observe what has happened.
The celery has changed its colour because it has drunk
the contaminated water. Now it is also contaminated.
If we dump garbage into the rivers and lakes, the water
will become poisoned and it will poison the plants and animals that
drink it.
