Chemicals in our food: A Context for Year 7 - 10 Science

Teacher Professional Development presented by LENScience in conjunction with the Department of Chemistry, University of Canterbury


The last 100 years has seen the development of a vast array of new chemicals that have changed the world around us – the paints for our cars, the plastics to pack our food in, the red dyes on the MacDonald’s fries packet, the batteries for our cell phones, the yellow dyes we give our hens to make sure they lay yellow-yoked eggs, and so on, and so on… The problem is that every day we are all exposed to hundreds, if not thousands, of different chemicals from the air we breathe, the food we eat and the water we drink. The question is what are all these chemicals doing to us and should we be worried?

This professional development seminar will:

  1. introduce teachers to the science behind environmental pollutants
  2. discuss implications
  3. outline the potential to use this context in teaching
  4. present resources to support the use of this context in Year 7-10 Science
