Jessi from SciShow Kids explains how humans and animals cool down. While humans sweat to cool off, dogs pant and lick their noses. Koalas, living in hot Australia, can't sweat or pant, so they hug trees to stay cool. Trees are cooler than the air, helping koalas regulate their temperature without losing water. The video concludes with an invitation to explore more science topics.

What is one way humans cool down when they get hot?

• By sweating

• By panting like dogs

• By hugging trees

• By licking their skin

Why can't dogs sweat all over their bodies like humans?

• They lick their paws instead

• They prefer to pant

• They have too much fur

• They don't have sweat glands

What is a major challenge for koalas in keeping cool?

• They drink too much water

• They can't sweat

• They live in cold climates

• They have thick fur

How do koalas primarily get the water they need?

• By eating leaves

• By drinking from streams

• By panting

• By licking their fur

What unique method do koalas use to cool themselves?

• They hug trees

• They swim in water

• They roll in mud

• They dig burrows

Why do koalas avoid licking themselves to cool down?

• It attracts predators

• It makes them too cold

• It is uncomfortable

• It uses up too much water

What did scientists discover about the temperature of trees compared to the air?

• Trees have the same temperature as the air

• Trees are cooler than the air

• Trees change temperature with the air

• Trees are warmer than the air

Why don't other tree-dwelling animals hug trees like koalas?

• They have other cooling methods

• They are not as clever as koalas

• They don't need to cool down

• They prefer to stay on the ground

What is the main reason koalas hug trees?

• To hide from predators

• To find food

• To sleep comfortably

• To cool down

What is the main topic of the SciShow Kids video?

• How animals communicate

• How animals find food

• How animals sleep

• How animals keep cool
