These Mastery Learning exercises could form the science work for a class for two weeks. The exercises could be discussed first in a teacher-centred session. A group discussion could be held for 10 of the 20 exercises over a week.
Which class could study these questions?
Several questions could provide the basis of a research project in the library. A selection could be on the end-of-module achievement test.
What are (1) warm blooded and (2) cold blooded animals?
Name 5 warm blooded and 5 cold blooded animals.
How do warm blooded animals (1) keep warm and (2) stay cool?
How do snakes and lizards warm themselves?
What effect does night have on snakes and lizards?
Why do fish not need to sleep in the sun?
How do people (1) stay warm and (2) keep cool?
How are whales and seals able to swim in cold seas?
Why may our skin turn blue when we are cold?
How does a blanket warm our body?
Does a dead body warm if covered with a blanket?
How does a sleeping bird keep warm at night?
What parts of our body do we have to keep warm?
Why do trekkers wear caps on the Kokoda Track?
How does a dog cool its body?
Why do some animals have long ears?
Why do birds migrate from Europe to Africa?
Why do they breed in Africa?
When do they go back to Europe?
Why do we have fever when our body is sick?
How did the passengers on the Titanic die?
A Department of Education Mastery Learning design team could gather such mastery questions in a half hour brain-storming session. These questions have been selected to enable focus on the range of questions on heat of the body.
Why do the birds migrate to Africa? They are following the sun. It is all about keeping warm and breeding. When do they go back to Europe? When the sun moves north. It is the tilt of the earth that makes the sun appear to move between the Tropics of Cancer and Capricorn.
