CHANGES OF STATE (Unit 6-Science Y5)

Today we are going to finish the topic of MATTER. Also we have learnt about PROPERTIES OF MATTER and CHANGES IN MATTER. 
Finally we are going to get to know the CHANGES OF STATE.

First we will watch this video, even though you have to answer these three questions on your notebook:

• How many states of matter are there?
• How many changes of state are there?
• Can you explain to the rest of the class any change of state?

The video is on this web page:

Also we are going to make the test yourself in common.
