The Moon
I would teach a lesson based on The cycles of the moon. First I would start with a KWL chart to elict what prior knowledge the children have on the moon.
Next I would play the video paxi & the moon phases. We would observe how the moon rotates around the earth and how the phases of the moon appear differently based on depending on the hemisphere in which you live.
We would do an extention lesson on space travel and the first man to walk on the moon. We would watch the video of Neil Armstrong and discuss how he needed space suit / zero gravity etc .
A few years ago I had the opportunity to visit the museum of Cosmonautics in Moscow. I would show photos from my visit and learn about Laika the first dog in space.
We would make a model of the moon during art class – paper mache. And further develop this into learning about the moons place in our solar system.
