Ways to Teach... Space

The Physics Teaching Podcast

Space is a challenging subject to teach, so a good subject for the first “Ways to Teach…” of this academic year.

Thomas and Robin start with a look at some physics in the news. The proton is smaller than we thought! About 5% smaller which will make it even harder to find one if you lose it, but let’s not be negative…

In other news, a new wonder-polymer promises transparency, strength and lightness all in one. Will it be as successful as graphene (which Robin made the mistake of questioning in front of an engineer).

And so to space. If there’s one message (and thanks to Dr David Boyce and others for this advice) try to use models, demos and activity to show what’s going on. It’s tempting to think you can’t do anything other than PowerPoint and YouTube for this topic, but whilst the odd video of cosmic phenomena can be great, you can make this subject live in the classroom.

So whether it’s “phases of the egg” or redshift on a balloon, try to get students involved in the subject. Living orreries, using beachballs to represent the sun and modelling the solar system’s scale with a beachball and a pea – all this and more is in our first “Ways to Teach…” of 2022.
