For threats to the earth topic. Complete lesson that was done for an interview that was 30 min long. This could be adapted though to fill a full 50 -60 min as there are opportunities for it to be adapted to enable the students to do more tries and complete a graph on paper rather than a class graph only.

This is a 30 min lesson that could be easily extended to a full lesson with class feedback and other activities linking energy transfer in a real situation. I did 3 demos of fuels so students could see that not all fuels are traditionally though of as fuels. the demos were blowing custard powder/icing sugar into a bunsen, whoosh bottle (big water cooler bottle with a small amount of ethanol and ignite it - it looks like an upside down rocket) and methane bubbles. It really engaged them and they really enjoyed putting ideas about the true or false cards.

An independent learning lesson on the Doppler effect, what it is and how it relates to sound. the power point contains the basic lesson and links to YouTube for the big bang theory and a little explanation clip.\nI printed out the information cards and placed them around the room for students to collect the information from. \nThe students then were responsible for their learning and collecting the information from around the room.
