Objects weigh __________on the moon than they do on Earth.
If you weighed 120 lbs on Earth then you’d weigh _____lbs on the Moon.
If you weighed 240 lbs on Earth then you’d weigh _____lbs on the Moon.
If something weighed 80 lbs on the Moon then it would weigh _____lbs on the Earth.

How did scientists begin to estimate the average distance to the moon?
What purpose did leaving the mirror on the moon serve? A Beam of light was bounced fro the Earth off the mirror. They measured the amount of time it took the beam to bounce back to the Earth. A beam of light was bounced from the Earth off the mirror that was on the moon. They measured the amount of time it took the beam to bounce back to the Earth. Then using the speed of light, they could then calculate the distance to the moon accurately.
Astronauts also brought back samples of _________________.

The Moon takes _______to rotate once on its axis. Almost a month!

About 4.6 billion years ago a lot of space debris was floating around our Solar system. A giant asteroid (the size of Mars) hit the Earth and tore a chunk out of Earth’s surface. The pieces that flew off is now our moon (the pieces merged together in orbit due to Earth’s Gravity.) **The hole that was left on Earth is now the Pacific Ocean. **This is also supported by moon rocks.
