Today we read about thunder and lighting. Did you know that as lighting streaks through the air it causes the air around it to heat up and expand. It expands so fast that it makes a noise- thunder!
We did an experiement after reading showing how warm air expands. The video shows Weston putting the waterbottle in hot water and then in cold water.
