In this activity, students are introduced to the interactive What killed the dogs? After working through the interactive, they consider the processes used by the toxicology scientists a little more closely.

By the end of this activity, students should be able to:

  • identify a given toxin using known chemical structures
  • explain what a molecular formula is
  • explain in simple terms how liquid chromatography-mass spectrometry (LC-MS) can be used to detect toxins
  • show an understanding of the concept of LD50
