Number (negative numbers): Extreme Environments
The Problem
Look closely at the thermometer opposite. Notice the arrows. Each arrow points to a different temperature. These ‘extreme’ temperatures are temperatures that some remarkable animal species can withstand (survive in).
Can you identify the name of the animal species and the temperature that it can withstand by using the clue cards below?
Teacher note: For reading support, suggest that the silver ant or the emperor penguin would both be good cards to start off with.
Did you know?
On land, the animal that can cope with the highest temperatures is a desert-dweller called the Saharan silver ant. Its body is covered in silver hairs that reflect the sun’s rays.
