I am outting myself here as a huge nerd from childhood. When I was growing up I used to LOVE watching Bill Nye the Science Guy on TV. I actually think at one stage I even wrote him a fan letter because I wanted to do exactly what he did when I grew up. He made Science look so fun and cool.
Flash forward to the other day when I was watching Epic Rap Battles: Sir Isaac Newton vs Bill Nye and my Year 13 girls actually asked me who is Bill Nye the Science Guy (insert startled look and gasp here). After I recovered from the shock I set about looking for some old episodes and found this:
Bill Nye Archive for Education on YouTube. Full episodes of Bill Nye the Science Guy! These are suitable definitely for junior school but my seniors enjoy them as a treat for times like when we are about to start a new topic and I want them to just think about the bigger picture rather than the maths and details.
