Changes in Motion of the Moon

ORDER NOW

TTN -1 Through the course of one night, you should have taken a minimum of 4 separate observations of the Moon, spanning a minimum of 3 hours (from start to finish), separated by 1 hour apart.
• Draw the path of the moon over that time with a dashed line through your sequence of observations, on your landscape.
• Describe the path you have drawn. Somewhere in your description should be terms such as “rising from”, “moving across”, or “setting towards”, and reference to compass directions as well as left and right. Imagine yourself outside, tracing the motion of the moon with your arm. How would you describe that motion? There is no need to explain what you saw, just describe the motion clearly.
Answer:
TTN-2 How much did the moon move? Words like “a little bit”, “a lot” or “an impressive amount” are not useful in science. State the overall average amount of motion in degrees per hour (this should be one averaged number), based on your own observations.
Answer:

TTN-3 Explain why you think the Moon changed its position in the sky as it did, through the course of one night’s observations. What causes the motion?
Answer:
Changes in Shape of the Moon

TTN-4 Did the shape or orientation of the illuminated part of the Moon change over the time of an observation sequence? If it did change, use specific and descriptive words to describe the change.
Answer:

TTN-5 Were there any other changes in the appearance of the moon over a given observation sequence? Were those changes due to the movement of the moon or to other phenomena?
Answer:

TTN-6 Explain why you think the apparent shape or orientation of the Moon changed or did not change through the course of one night?
