Atoms, Elements, Compounds KS3 quiz on powerpoint.

I created this quiz for my year 7’s who had completed the Elements, Atoms, Molecules, compounds KS3 unit.
It has 15 multiple choice questions on a powerpoint presentation.
It includes questions about the meaning of key words and identifying atoms, elements and compounds from particle diagrams.
There is 1 question per page and the students have 20 seconds to read the question and choose from 3 answers before the page automatically turns. There is a countdown to every page turn.
I created these quizzes as a fun way to reinforce main points covered in the topic so far. I had a particularly lively group and wanted to settle them down quickly at the start of the lesson and found that this worked really well.
They sit in silence for the 300 seconds of the 15 question run. I usually then choose names randomly to answer each question. It provides a good opportunity to discuss main points and clarify any misunderstandings. All my groups have embraced the quizzes really well and appear to enjoy them.
The questions may be a little too simple for top set groups, but it could confirm their understanding; which is always useful; and of course – boost their confidence!
