In Science 3L are focussing on how solids and liquids change state. We have identified what the three states of matter are (solds, liquids and gases) and have made predictions on how solids can become liquids and how liquids can become solids.

This week we conducted an experiment on 5 different liquids - milk, oil, honey, vinegar and water to see what would happen after we removed the heat.The first part of the experiment was to predict what would happen to each liquid after it had been in the freezer for 2 hours and again after 4 hours. We then observed the liquids after these times, wrote our observations and then compared our predictions to our observations. 

Some interesting observations were:

The vinegar froze within the first 2 hours;

The milk had ice in it but was not frozen on the 2 hour check but it was on the 4 hour check;

The honey turned into a gel but it did not freeze, it became thicker as time went on;

The oil stayed exactly the same.
