P5 Wonderful Water

Water, water all around…

This week we have continued looking at water and followed up our water cycle learning by focusing on the states of water.  We discussed ice (solid), water in it’s natural state (liquid) and water vapour and steam (gas).  We conducted an investigation into what would happen to water if placed in different environments in the school, the freezer, on the heater and left under our smartboard.  We discussed what would happen and any changes we would observe.  We learned that the term hypothesis means to predict what would happen using some of our prior knowledge about the subject.  We all agreed that the bottle in the freezer will turn into ice, here are some other suggestions as to what will also happen,

“I think the water level will go down because the water will get thicker when it turns to ice”.

“I think the water in the freezer will rise because that is what usually happens”

We recorded our findings and observation in our class “Talking Book”.

The picture shows that the frozen water has risen up the bottle.  We discussed how the structure of the water molecules causes this to happen.  If you want to up level this knowledge further watch the following youtube science clip which explains this and more.
