A 17 slide powerpoint covering material testing in readiness for NEA. This focusses on testing techniques you can easily do in school (tensile, hardness, toughness, energy (heat) transfer etc.
Within the powerpoint are photographs and videos of each test taking place in the workshop (they are made by me - not just a youtube video).
The theory works as a standalone presentation, but if you wanted to make your own testing rigs, I have made a few simple contraptions to make testing more controlled which are also shown in the powerpoint photos/videos in use - all 3 would be easy to make in any DT workshop in a few hours.
There is an accompanying handout for recording any practical tests that students do.
Always one of the favourite lessons of year 12, and they get to complete a piece of NEA in the process too!
As with all my lessons, they come with a retrieval exercise to begin and relevant exam questions (with mark scheme) to conclude.
