Product Design Engineer by specialism and perfectionist by nature!
I plan to keep updating this shop with high quality resources, lessons, worksheets, and full projects that you should be able to just take and use or adapt as you need for secondary design and technology lessons.
KS3 Design and Technology, GCSE Product Design, AQA GCSE 1-9 Design and Technology, A-level Product Design, IBDT
This is a whole lesson that will need you or your technician to build one of each of these circuits before the lesson to be used for the students to experiment with.
