Homeostasis

Comments (0)

This resource from Defence Dynamics helps students to gain a better understanding of homeostasis and, in particular, the regulation of body temperature (thermoregulation). Students consider the needs of a polar explorer on a mission to the South Pole, thinking about the equipment needed as well as the challenges the body undergoes in such an extreme environment.

Polly Hatchard was one of an all-women team who trekked to the South Pole. Audio clips describe the preparations and some of the problems she faced during her expedition to the pole.

The audio clips are:
• Introduction - the lead up to the expedition
• Challenges - conditions and challenges of the
• Equipment - what basic equipment is needed
• Four clips:
- Food (start) - the types of food carried on the expedition
- Cold (2min10sec) - staying warm
- Coping with sweat (4min15sec)
- Unusual effects (6min0sec) - some odd effects on the body of the cold
