KS2 CHALLENGE OF THE WEEK

See what you can do this week...

Next week is Science Week in school.

Our challenge is to try an experiment at home.

Can you find 3 substances that dissolve in water and 3 substances that
do not?

Note what happens to the substance and the water.

Then use a measuring jug to find 100ml of water.

How many teaspoons of salt can you dissolve into 100ml of cold water?

Do you think you would get a different answer if the water was warm (not boiling)?

Good luck with your research and
remember—don’t start an experiment
at home without checking with an adult first.
