I add new videos to my Teaching Videos site on a regular basis, using a number of Youtube subscriptions to find useful videos (as well as videos shared on Twitter and in my RSS subscriptions). One Youtube channel that I particularly enjoy checking is for Steve Spangler Science.
Steve is a science author, teacher, professional speaker, toy designer, a television personality and a big kid! His Youtube channel shares lots of big Science activities and events that he has been involved in. However, there are also a number of Sick Science videos which feature tricks and experiments that can be played in the classroom. Theyre great for provoking discussion about how the trick works and talking about the Science concepts involved.
You could also try to recreate the experiment yourself as lots of them involve everyday classroom objects. Heres an example:
If you have any favourite educational Youtube channels, please as I would love to hear about them!
