Life Skills
Like humans, animals use various methods to cool their body temperature in summer.
For example, rabbits, foxes, elephants have thin skin paired with blood vessels near
the surface in their ears to help shed excessive body heat. Bees carry water droplets

back to their hives and fan them with their wings to effectively create their own air
conditioning, Kangaroos salivate on their forearms to beat the harsh Australian heat.

Conversion Between Celsius and fahrenheit scales

Celsius (°C) to fahrenheit (°f)

9
To convert the temprature from °C to °F, multiply °C by and add 32.

That is F = C × + 32
