Draw a diagram that shows high and low tides. Do NOT put the moon in any of the following positions: new moon, full moon, 1st quarter, 3rd (or last) quarter.
Did you put the moon in one of the following positions? Waxing crescent, waning crescent, waxing gibbous, waning gibbous....
300
What is the cause of daylight and night?
Earth's rotation
300
What color is the moon during a lunar eclipse? Why does this happen?
The moon is red during a lunar eclipse because the sunlight coming through the Earth's atmosphere has the blue light absorbed, leaving only the red light to reflect on the moon.
300
What is the main source of gravity that causes tides?
The moon
300
What happens during a total solar eclipse?
During a total solar eclipse, the moon appears to fully cover the disk of the sun
300

Winter
400
Earth's rotation on its axis is a direct cause of ____________.
Daytime and Nighttime
400
What causes the phases of the moon?
The phases are caused by changing the relative positions of the Earth, sun, and moon.
400
How often do high tides occur?
Every 12 hours
400
Why don't solar and lunar eclipses occur every month?
They do not occur every month because the moon's orbit around the Earth is at a 5 degree tilt
400

Name the dates for both equinoxes and solstices. Label which is the longest day of the year, the shortest day of the year, and which are the first days of summer and winter.
Vernal (spring) equinox - ~March 21 Autumnal (fall) equinox - ~September 21 Winter solstice - ~December 21, shortest day of the year for northern hemisphere, first day of winter; Summer solstice - ~June 21, longest day of the year for northern hemisphere, first day of summer;
500
Draw diagrams that represent the differences between neap and spring tides. Be sure to label tidal bulges and where the high and low tides will occur.
For neap tides, did you align your two moon drawings at a 90 degree angle to the Earth and sun? For spring tides, did you align the moon, Earth, and Sun? Check your tidal bulges, and your labels of high tides and low tides!
