Growing Crystals

Today we made sugar crystals. 

First we made a saturated solution. This means we completely dissolved the sugar into water over heat. 

Next we set up our cup with an ice-block stick and string dangling into the cup.

Then we poured the sugar solution into the cup and made sure our string was dangling into the solution. 

Then we put our cups onto the window sill.

Our predictions:

• The water will evaporate and the sugar crystals will stay behind and grow and stick to the string. 

Scientific vocab we learnt today:

evaporate

dissolve

saturated solution
