For anyone trying to plan something creative to allow various science skills to be developed. This project/lesson has so much scope. At a push this could be done in a lesson and then perhaps for homework but it would work a lot better if a few of hours of time was given to make a good job of it! The project would sit nicely anywhere within the year or would make a great end of term activity as it is a completely ‘stand alone’ topic. Perhaps you could use this in a STEM week or during Science week? This bundle of resources contains powerpoints to guide through the project as well as teacher/technician notes, lesson plans, plus some suspect profiles to work out ‘whodunnit’. I have included a student worksheets to allow them to gather and record data and draw conclusions. Students will need to carry out practical activities as part of this project so only download if you have the capacity to set these up! Students will have to consider how to control various elements of the project/investigation and how to improve accuracy, repeatability, precision etc. They will then need to plot graphs of their results, draw observations from microscopes and carry out chemical food tests before drawing a final conclusion. I love using this resource! It is fully editable but gives you a resource you can use straight away (you’ll just need to talk to your technicians about making some fake blood, urine and hair and fibre samples…).
