July 19, "Helicopters"

This class was the last class about air and its properties.

As a round up, we reviewed everything we have learned about the air so far. We recollected that wind is air, wind is strong and can move things; and that we cannot see air. We also remembered our song about bubbles.

Then we learned an action poem "Helicopter" to see how a helicopter moves through the air.

Helicopter goes up,
Helicopter goes down,
Helicopter turns and turns around,
Helicopter goes left,
Helicopter goes right,
Helicopter goes up, up, and out of sight!
 

Then we went on to make our own paper helicopters. We had 3 designs: a fish, a  triangle and a rotor one. They were premade so all we had to do is tape them together. The we experimented with the models: we saw the patterns of how they move through the air and figured the best model.

Home practice:  I recommend you to make a paper airplane or a kite with your scientist and help him/her fly it to explore how things move through the air.
