This document summarizes experiments conducted by children ages 5 to 7 about the properties of water. The children made predictions about water and recorded their observations and discoveries in worksheets. Some of their predictions were correct and some were incorrect. The experiments explored states of water, floating and sinking, mixing materials in water, and the difference between fresh water and salty water.

1. EXPERIMENTS WITH
WATER
C. P. VILLAPENDI

2. ● This experiments were made by children
five to 7 years old.
● They used their knowledge about water to
make predictions.
● Some times their predictions were right,
some times were wrong.
● They recorded their discoveries in
worksheets
● We related the experiments with nature
facts, like water cycle, river pollution...

3. This term we have
learned many things
about water.
Let's see...

4. Tap water is a liquid:
it has the shape of
the container
The glasses are different
but the amount of water
is the same

5. When you put water in the freezer it becomes
ice. Ice is solid.

6. You can't take liquid
water in your hands, but
you can take ice.
It's cold!

7. When you heat water on the fire, you get steem.
Water steem is vapour

8. If you cover
boiling water
with a cold dish
you can get rain
in the kitchen.

9. You can't hold
water steam. It flies
into the air.
Water steam is hot

10. Some things float on the water
and some sink

11. The cork,
the wooden spoon,
the pencil and
the plastic ruler float.
The metal spoon,
the sharpener
and the rubber
sink.
Some materials
are lighter than water
some are heavier.

12. Some things mix with water, some not.
We checked several things:

13. Sawdust doesn't mix with water

14. Oil never mixes with water, you can stir,
and stir... but it always goes up.
It floats on the water.

15. Oil is very
difficult to
clean when it
reaches rivers
or the sea.

16. Vinegar mixes with water

17. You can mix
honey with water,
but after a while it
settles down

18. Sugar melts in water and it disappears

19. Salt also melts in
water and disappears.

20. This way you get
salty water

21. If you put
an egg into
fresh water,
it sinks.

22. If you put it
into salty water,
it floats.

23. We put a few
drops
of
food coloring
into
fresh water

24. Then,
we poured the
coloured fresh water
onto the
salty water.
What happened?
The fresh water
floats on the
salty water
because it is lighter.
