What

xmphysicdemo is a youTube channel that features videos of physics demonstrations related to A-level Physics.

Why

Usually, a live demonstration is the best. But a filmed demonstration does have many advantages over a live one.

Slow motion

Many physics phenomena happen so fast our brains cannot register the event. High speed video is very helpful in these situations.

Annotations

Sometimes, all it takes is a few lines added through video editing to turn an ordinary video into an insightful one.

Projective motion: http://youtu.be/Wxw2GY804t4

Music

Some demonstrations are more enjoyable and impactful with background music.

Size issues

Many small size demonstrations are unsuitable for lectures because audience seated far away cannot see the necessary detail. Filming and playing the demonstration on the big screen solves the problem.

Logistical issues

Videos allow demonstrations involving heavy and bulky equipment to be brought to classrooms easily.

Demo on demand

Let’s face it. Many schools are well equipped with demonstration sets that are under-utilized due to various reasons. Demonstrations videos, on the other hand, are accessible to a global audience round the clock.


How

Media resource for lectures or tutorials

Demonstration on video are very effective resources for daily lessons. Many demonstrations are good triggers for discussion and teaching of new concepts.

Inquiry learning

What do we get when we pair URLs to videos of physics demonstrations, and well-designed probing questions? An inquiry learning worksheet.
