Revolution • Definition: When the Earth makes a complete circle or orbit around the sun. • What is the direction of movement? Counterclockwise • How long does it take? 365 days/1 year • What is the rate? 100, 000 km/hr • Results of motion? Seasons with the Earth’s tilt and orbital speed • How can you prove this motion? Changing constellations and parallax

EXIT: • Complete questions 1 and 2 on your note packet page 5. Be prepared to discuss.

• SWBAT: Define rotation and revolution and provide proof for both motions.

Open packets to pg 4 • Do Now: Quick Write. Take about 3 minutes to write the difference between the revolution and rotation of the earth. Write down what comes to mind what these motions cause etc. Be prepared to share your quick write with the class.

How long is one rotation of Earth? How long is one revolution of Earth?

Rising and Setting ofofthe the. Moon Sun Movement of Stars The Seasons Changing through the sky Constellations

One rotation = 360° Time for one rotation = 24 hours 360° ÷ 24 = 15°/hr

How many degrees did the stars move 30° (2 hours x 1 15°) from diagram to diagram 2?

How can you find It’s the only one that didn’t move Polaris?

What Northern hemisphere mustcan youonly be in? Because Polaris been seen in the North Why?

What direction must North you be looking?

What direction do the stars appear to move?

What causes the stars appear to move?

• Turn to page 5 in your packet and begin working on questions 3 -10

EXIT: • On your index card describe why we can’t see the same constellations all year long.
