In science we learnt that the average body temperature is 37'C. When we are cold are body shivers to try to warm us up. When we sweat, it is our body's reaction to try & cool us down. When we are sick we get a fever.
I can recognize that the human body temperature is relatively constant and that a change in body temperature often signals a change in health.
We learnt about the Northern Lights. Northern Lights or the Aurora Borealis - the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. We also watched The Legend of the Northern Lights.
