We tried to dissolve salt in water with different temperatures – hot, warm and cold.

We had to guess which would dissolve the fastest.

2 of us though the cold water and 2 of us thought the hottest water.

We carried out the experiment and guess what…..?

The cold was the fastest but it wasn’t supposed to be – we think Molly just did a great job with the stirring.

The hot is meant to dissolve the salt the fastest because hot water has more energy and can make the salt change from a SOLID to a liquid more quickly.

Dissolving means that a SOLID goes into a liquid to create a solution which is a mix of the 2.  Even if you can’t see the salt it is still there.

Have a look at our photographs.
