Will everything freeze?

.As part of our kitchen science experiments we wanted to see if everything we put in water and then in an ice cube tray in the freezer, would freeze....this is what we found out!

We put a lolly, some sultanas, a grape, coffee powder, salt, tomato sauce, rice, sugar and just water on its own into 3 ice cube trays. We left them in the freezer for a week and then checked to see if everything froze. 

We predicted that EVERYTHING would freeze but...

                                                       The salt did not!!

We could still feel the grainy salt that was in the water in the ice cube tray.

The water around the lolly froze, but the lolly was still sticky and not frozen!

                                             Everything else froze.

We need to investigate why the salt and the lolly did not freeze. We really enjoyed this experiment. What could you try this at home with? We'd love to hear about your experiments with freezing!! 

Thank you Casey for taking great photgraphs!
