Primary 5 and Primary 5/4 have been learning all about SOLIDS, LIQUIDS and  GASES and their properties.  We looked at the main characteristics of each state of matter.

Emma – I learned that some solids are hard and can’t be molded into a shape without force. The molecules in a solid are packed close together and they don’t have much movement.

Molly- I learned that liquids are made out of particles that are more spread out compared to solids and have some movement. Liquids do not have a fixed shape but take the shape of their container.

Sami – I learned that the particles in Gases are spaced out and can move around freely. Gases do not have a fixed shape and can change volume.

We watched videos to learn about different experiments we could carry out. We then had a go at some of these in class, this got a bit messy!

We used a Kettle, cling film and ice to learn about condensation and evaporation.

We also experimented with different material to see what dissolves. We learned sugar, gravy granules and coffee granules are soluble and sand, chalk, flour and rice are insoluble.

Today we went to school kitchen to find out what changes in state are reversible or non-reversible. We carried out this experiment by heating different foods  to melt them then we placed each item in the fridge to cool it back down. Tomorrow we will check which change in state are reversible.

WE LOVE SCIENCE!!!
