Energy and change

Classroom resources featuring activities from our Energy and Change professional development course for teachers

This collection is most valuable to those who have attended this course and wish to put into practice with their students some of the ideas and activities presented as part of that event. Please note that this list is not exhaustive; not all trainer activities have a corresponding classroom resource. In some circumstances there is variation between the training resource and classroom resource.

Beyond appearances

Reviews of research on students’ misconceptions in conceptual areas of chemistry. Misconceptions are described and discussed, together with indications of their origins.

Bubbles

Exploding soap bubbles

Soap bubbles containing a mixture of oxygen and methane can be used to produce spectacular explosions and impressive shock-waves that will always please
