What different changes have we investigated?
Why is categorisation important? Why classify things?
What if we didn’t classify things?
During this lesson students will group the changes which have been investigated as part of the unit.
We are going to use a Venn diagram to visually represent the information.
On the changes card sort there are 10 different cards. Students must use a venn diagram to sort the cards into sets, and explain why you believe that card should be in that set.
The Change Card Sort include;
Dissolving sodium bicarbonate
Fizzing sodium bicarbonat and tartaric acid in solution
