a question based on the white blood cells and how it proctects against illness. the image file is how i presented it to the students and looked at the banding of the marks. we went through what was required and i explained that 6 points were not enough and that it was more about the structure of the answer. the model answer sheet shows the students what is required to gain the full 6 and an A*. hope you find it useful.

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. Some of the power point and the all of the plenary pyramid were off of this site so sorry for reposting but without them the lesson is not complete!

This is a 30 min lesson that could be easily extened to a full lesson with class feedback and other activities linking energy transfer in a real situation. I did 3 demos of fuels so pupils 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.
