Year 12 Biology Students Explore Homeostasis at Perth Zoo
Our Year 12 Biology students spent the afternoon surrounded by native and exotic animals that provided them the opportunity to connect their classroom learning to real life examples.
The goal? To bring the concept of homeostasis to life by seeing firsthand how different animals manage to keep their internal environments stable, even when the conditions around them are constantly changing.
From Cold-Blooded Reptiles to Cosy Penguins
It was an afternoon full of discovery. Students got up close with reptiles like the spiny-tailed skink, Stimpson’s python, and the blue-tongued lizard, all ectothermic animals whose body temperature fluctuates with the temperature of the environment.
Then came the contrast: mammals like the tammar wallaby, western grey kangaroo, and a variety of African savannah animals, which maintain a constant internal temperature no matter the weather outside. It was a great way to see just how differently animals have adapted to survive.
And of course, who could forget the fairy penguins? These little characters were a clear favourite. Students were fascinated by the clever adaptations they use to thrive in colder climates, like feather insulation, countershading, blubber, and a low surface area-to-volume ratio. It was a real eye-opener into how evolution has shaped survival.
Real Animals, Real Learning
One of the best parts of the day was getting up close with some of Australia’s native wildlife. Students had the chance to observe the finer details of thermoregulation in both marsupials and reptiles. It was a powerful way to link what they had learned in class with real, living examples, sparking connections and thought-provoking questions.
The learning didn’t stop there. At the primate exhibits, the conversation turned to the evolutionary relationships between humans and our closest living relatives. The highly social nature of the lemurs, cooperatively living in family groups, provided an opportunity to appreciate the origins of the social nature of humans.

“The Zoo Was Absolutely Amazing!”
The whole experience made biology feel real. Students left the zoo with a deeper appreciation for the complexity of life, and plenty of practical examples to help cement what they’ve been learning in class.
“The zoo was absolutely amazing; it was so fun and educational. I had no idea so many animals have different adaptations for thermoregulation, like the penguins that have the structural adaptation of dark-coloured feathers to attract the sun’s heat,” said Lily, Year 12.
“One highlight for me was seeing the fairy penguins in action and connecting it to their thermoregulation adaptations we’ve studied. It was amazing to apply our learning in such a real-world context!” said Emily, Year 12.
From penguins to pythons, it was a day of learning and laughter, proof that sometimes the best classroom has feathers, scales and four legs.
