Eclipses
Learning Goals:
- Explain how eclipses occur
Task A - Notes
1a) Find a diagram of a lunar eclipse. Make sure it has the following labels: umbra, penumbra, moon, earth, sun (put into your notes)
1b) Describe how a lunar eclipse occurs (include the order of sun, moon & Earth + the word's earth's shadow)
2) Define: penumbra shadow, umbra shadow
3) Explain (use diagram) how penumbra leads to partial eclipses and umbra leads to total eclipses
4) Lunar eclipses last longer than solar eclipses. Give the reason why.
5) In what phase of the moon do lunar eclipses occur? (full or new?) A sketch here could be useful
Solar Eclipse Questions
1) Find a diagram of a solar eclipse. Make sure it has the following labels: umbra, penumbra, moon, earth, sun (put into your notes)
1b) Describe how a solar eclipse occurs (include the order of sun, moon & Earth + the word's moon's shadow)
2) Why is there not always a solar eclipse every new moon?
3) Solar eclipses provide a good chance to study the moon. Explain why this is the case and describe what can be seen.
4) During a solar eclipse the corona of the sun can be seen. What is meant by 'corona'?
*Extension
1) Use a diagram to explain annular eclipses
2) Use http:// www.rasnz.org.nz/eclipses.shtml to find out when the next lunar and solar eclipses occur for New Zealand
3) Use this link to explore the google map of the total solar eclipse for Dunedin for 2028. Choose exactly where and when you will be viewing.
4) Explain why lunar eclipses cause "blood moons", find the name of the type of scattering which causes this (and also red sunsets and the blue sky!).
