Learn about the moon as a natural satellite, eclipses, and predicting the moon's appearance from Earth. Study diagrams and pictures to determine its position and phase.
E N D
The Moon Learning Objectives: • Recall that the moon is a natural satellite • Explain what causes an eclipse • Predict and draw what the moon looks like from the earth in eight positions of the moon’s orbit. • Determine the position and phase of the moon from a picture of its appearance on earth. http://www.sumanasinc.com/webcontent/animations/content/moonphase.html
Starter • Put these in order from smallest to largest. • Solar System, Earth, Moon, Sun
The Moon • Satellite= object that orbits another object • The Earth is a satellite of the Sun. • The moon is a satellite of the Earth • The moon orbits the Earth once every 27 days.
How do we see the Moon? • The moon does NOT give out any light. • We can only see the moon because light from the Sun reflects (bounces) off of the moon and hits the Earth.
Solar Eclipse • A solar eclipse is when the Sun is blocked out by the moon’s shadow and it becomes dark during the day.
Lunar Eclipse • A lunar eclipse is when the Moon is blocked out by the Earth’s shadow and it appears red.
Examine the picture • Which direction is the light coming from? • How do you know where the light is coming from? • Describe how the balls appearance would change if you looked at it while you walked a full circle round it.
You will see the moon in 8 positions For each position predict and draw what the moon will look like from earth
Earth moon and sun View of the moon from the earth
Study the diagram What patterns do you notice? Explain What happens to the illuminated side after the full moon? Explain How could you work out the position of the moon from the picture of its view from earth?
This time you will see 8 pictures of the moon from the earth For each picture: • Name the phase • Work out the position A – H Try this without your diagram
