8.7A - Rotation vs. Revolution Seasons Watch the video BEFORE answering the questions. It takes the Earth 24 hours to rotate on it's axis. It takes the Earth 365 days to revolve around the Sun. Use the image to answer the following questions. At which location is it daytime? A B AB At which location is it summer? A B AB At which location is it winter? A B AB The day and night cycle on Earth is caused by the Earth's rotationon its axis. The Earth is closer to the sun in winterand farther from the Sun in summer. The varying distance from the Sun to the Earth is notthe reason for the seasons.Seasons are caused by the 23.5 degree tiltof the axisand the revolutionof the earth round the sun. Students are modeling the Earth, the Sun, and their relative motions. They have a basketball and a tennis ball. Fill in the blanks, then sort the correct statements that describe what the students should do in order to accurately model the cause of day and night on the Earth. The basketball will represent the sun. The tennis ball will represent the earth. Describes Day Night rotate the tennis ball on an axis rotate the ball (Earth) counter-clockwise Does NOT describe Day Night lift the tennis ball off the table rotate the ball (Earth) clockwise rotate the basketball on an axis move the tennis ball around the basketball Students are modeling the Earth, the Sun, and their relative motions. They have a volleyball and a golf ball. Fill in the blanks, then sort the correct statements that describe what the students should do in order to accurately model the cause of seasonson the Earth The volleyball will represent the sun. The golf ball will represent the Earth. Describes Seasons tilt the axis on the golf ball move the golf ball counter-clockwise around the volleyball Does NOT describe Seasons rotate the golf ball on an axis move the volleyball counter-clockwise around the golf ball rotate the volleyball on an axis tilt the axis of the volleyball Use the diagram to identify the seasons. What is the season in the Northern Hemisphere in Position 1. spring summer winter fall Between position 1 2 do the days get shorter or longer? shorter longer What is the season in the Northern Hemisphere during position 2? spring summer winter fall Between positions 2 3 do the days get shorter or longer? shorter longer What is the season in the Northern Hemisphere during Position 3? spring summer winter fall Between positions 3 4 do the days get shorter or longer? shorter longer What season is it in the Northern Hemisphere during position 4? spring summer winter fall It takes 6 months to get from Position 2 to Position 4, and 9 months to get from Position 2 to Position 1. 8.7B Lunar Cycle Watch the video BEFORE answering the questions. It takes the moon 27.5 days to revolve around the earth at one time. The moon revolves around the earth in a counter-clockwise direction. A waxing gibbous is the moon phase that comes after a first quarter moon. Use the following to correctly label the diagram: full moon, new moon, first quarter, third quarter. Be sure to type it EXACTLY how it is written in the word bank!!! new moon third quarter first quarter full moon Label each moon phase. Use the word FIRSTand THIRDfor the quarter. CHECK YOUR SPELLING! (Gibbous) (Crescent) new moon waxing crescent first quarter waxing gibbous full moon waning gibbous third quarter waning crescent It takes the moon one week to get from Position 1 to Position 2. It takes the moon two weeks to travel from Position 2 to Position 4. It takes the moon one month to travel from Position 3 back to Position 3. Which word best describes the changes in the moon's appearance during the sequence shown above? Gibbous Waning Crescent Waxing What is the name of the phase of the moon in the picture? Third Quarter Waning Crescent First Quarter Half Moon 8.7C - Tides Watch the Video BEFORE answering the questions. Tides are caused by the gravitational pull of the moon and sun. The moon has the greater effect on the tides because it is closer to Earth. Which two positions bring higher than normal tides? Positions 1 2 Positions 1 3 Positions 2 3 Positions 2 4 Sring Tide Full Moon New Moon Neap Tide First Quarter Third Quarter
