This first video is called Origins of the Moon. Don’t worry about the big words and the advanced math – this is just showing the same idea as the video from the Museum of Natural History. When Earth was first born, it had no Moon. Then, another planet too close by hit the Earth. The Moon was formed from that explosion. There was nothing living on Earth at the time. We’ve also talked a lot in class about how this could not happen again today because there are no planets that come very close to us.
Why does the Moon look like it changes? This shows some nice footage of the Earth, Moon and Sun together. It makes it easy to see how the Sun’s light makes one side of the Moon look bright. But, sometimes the bright side is facing away from us or only facing towards us a little bit. So, the Moon sometimes looks dark or has a crescent shape.
This calculator will show you what the Moon will look like on any calendar day. The day in the picture is Lisa’s birthday. Click on the picture to try it!

The Moon looks different each night because the Earth and Moon are always moving around the Sun. This game will help you to learn about how the Moon’s shape changes every day. What patterns do you notice?
Churchill Science has been active since June 2008. Since then, we’ve gotten hundreds of visitors from around the world. Here is a map showing some of the places where our visitors are from.
Just over the past three days, our site has been visited from all over the globe! Just from our own country, we’ve had visitors drop in from 16 states – New York (obviously), New Jersey, Pennsylvania, Massachusetts, Florida, Ohio, Indiana, Idaho, California, North Carolina, Minnesota, Texas, Wisconsin, Michigan, Virginia and Georgia.
We’d also like to welcome our visitors from abroad. In the last three days, we received hits from Italy, Australia, Brazil, England, Qatar, Israel, Chile, Indonesia, Malaysia, the Netherlands, Germany, and South Africa! All of the continents are represented except one – Antarctica.
Short of Lisa going back to Antarctica just to log on to Churchill Science, it doesn’t seem likely that we’ll get a visitor to this site from there. But wouldn’t that be great?
If you’d like to leave a comment telling us who you are and where you’re from, we’d love to know more about our visitors! Thanks for dropping by!
Watch what happens to the liquid inside the special cup. Why does it stick together like that?
Now we know what Lisa will be doing if she ever goes into space!

Questions:
-What is missing from this picture?
-What are the circles around the Sun and the Earth?
-Why does the Sun get to be in the middle?
-What do you think would happen if we took the Earth out?
Things to notice as you play:
-What happens when you go to big places, such as the Sun or Jupiter?
-What happens when you go to small places, like the Moon or Mercury?
-Why is the target floating on some of the planets and on the Sun?
Challenge: Find MORE THAN ONE WAY to hit the target!
The Moon is much smaller than the Earth. Therefore, it pulls less. Watch some footage from the moon landings to see for yourself!
Astronauts on the moon – notice how they get around. Are they walking normally? How much is the Moon’s gravity pulling them?
Dropping a feather and hammer on the moon – This experiment should look familiar. We did something like this in class together. The difference is – no air on the moon, so the feather won’t float. Also notice how much time it takes for both objects to hit the ground.
Throwing a hammer on the moon – Notice how high the hammer goes, and how long it takes for it to come down. What would that look like on Earth?
