  1. An Assessment • Best procedures: read quietly to yourself (so you don’t give any subconscious clues) • As the instructor, we read it too, for timing, then ask if anyone needs more time • If not, it’s time to vote simultaneously—use your fingers, right in front of your chest so others don’t see (anonymous) Northerners have cold days in January because • the Earth is farthest from the Sun in January. • the sunlight takes a longer route to get to the Earth in January. • the Sun is lower in the sky in January. • El Nino is always strongest in January.

  3. What would the days and seasons be like in Houston if the Earth still rotated at the same speed, but the Earth’s axis were tilted nearly 50 degrees on its side instead of 23 degrees? • Both days and seasons would last half a year. • The days would be the same length, but the seasons would be half a year long. • There would be no seasons, but days would be 6 months long. • The days and seasons would be the same lengths as ours, but the seasons would have more extreme temperature changes.

  4. An Assessment • Best procedures: read quietly to yourself (so you don’t give any subconscious clues) • As the instructor, we read it too, for timing, then ask if anyone needs more time • If not, it’s time to vote simultaneously—use your fingers, right in front of your chest so others don’t see (anonymous) In which case(s) can the Earth, Sun, and Moon be in a straight line, as seen from above the solar system? • full Moon only • first quarter and third (or last) quarter • new Moon only • both full and new Moon • This can happen at any phase of the Moon.
