A teaching tool for teachers to illustrate how to carry out fair tests.

Key Concepts addressed:

Details

In this investigation, students learn about carrying out a fair test, by running a blind trial of organic and non-organic herbs to see if they can identify any differences in taste. The investigation is put into a STEM careers context through an initial case study of James Seymour, a scientist who works as a Product Manager for a company growing herbs for major shops and supermarkets. This resource includes teachers’ notes, case study, students&’ worksheet & technical notes for the practical.
