Some fish contain proteins that act like antifreeze in order for them to live in the frigid waters of Antarctica! High schoolers determine how much antifreeze a fish needs to lower its body temp to -2.5 degrees. Teachers act as a facilitator while lab groups determine their procedure, conduct their experiments, and determine their conclusions.
- Read the background information as a class or independently for homework before the lesson
- Lab is set up so learners determine what to test and how (to a certain extent) and teacher is the facilitator; teachers can tweak this and give more specific directions as needed for classes
- Antifreeze and rock salt are two of the five needed materials, and you can find the rest in your science classroom
- Activity includes great extensions for higher level students
- You can find a simple handout for your class at the end of the lab
