THE MOON

On July 20, 1969, millions of people gathered around their televisions to watch two U.S. astronauts do something no one had ever done before. Wearing bulky space suits and backpacks of oxygen to breathe, Neil Armstrong and Edwin “Buzz” Aldrin became the first human beings to walk on the moon.

After the two stepped onto the lunar surface, Armstrong proclaimed these famous words: “That's one small step for a man, one giant leap for mankind."

Let’s remember the 2 kinds of movement that the Earth makes:

There is rotation, which is the Earth turning around itself... causing day and night... which lasts exactly 24 hours (a whole day).

And there is revolution, which is the earth travelling around the sun... which takes 365 days and causes the seasons.

So, now you know the movements of the Earth.

Watch the video!!

REMEMBER!

SEE YOU TOMORROOOOOOOOOOOW!!!
