States of matter


 Compare and group materials together, according to whether they are solids, liquids or gases. 


We will be identifying whether materials are solids, liquids or gases. Can an object be made up of more than 1 state of matter? The three states of matter have different properties. Which one can be poured? Which one fills the container or space?

Observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens in degrees Celsius (°C).


We will be exploring and observing how materials change state when they are heated and cooled. Materials have different melting points, which means that some melt at lower temperatures than others.

Identify the part played by evaporation and condensation in the water cycle and associate the rate of evaporation with temperature.


Evaporation and condensation are two processes through which matter changes from one state to another. Matter can exist in three different states: solid, liquid, or gas. In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid.


All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy in the form of heat.
