Patterns Lesson 3.1-3.3

What have we discovered about this object?

1. The four sections show different

views of the sky.

2. Each section is divided into two panels: one panel shows the sun in the sky and the other

the panel shows the night sky with other

stars.

3. One section shows the

constellation Orion in the night sky.

Earth's Orbit or Revolution

Causes us to see different constellations

The reason we see different stars at different times of the year

Where the earth is around the sun affects what season it is. Therefore, what constellations are on display in the night sky.

Multiple Choice

What happens when the earth orbits the sun

• it causes day and night

• it causes the seasons

• the ocean has waves

Every year we see the same Constellation

• Why do you think every year we see the same constellations?

• What part in the video gives you evidence that you can see the same constellations every year on the same date?

• When the earth revolves around the sun in 365 days, what happens after?

What causes us to see different constellations throughout the year?

• Each season there is different constellations in the

  night sky due to earth's orbit and it's tilt. 

  Different constellations are visible on different nights throughout the year because of the earth's orbit.

  The Earth orbits around the sun.

• Remember: Revolution=Orbit Rotation=Spin

Multiple Choice

Why do we see different stars at different times of the year?

• because the EARTH ORBITS the sun

• because the EARTH ROTATES the sun

• because the SUN ROTATES the planets

Why do we see the same stars every year on the same dates?

• Because the earth orbits the sun every year in the same way

• So as it orbits the sun yearly, the same constellations are in space

• Remember: Revolution=Orbit Rotation=Spin

Multiple Choice

What does the earth do around the sun which causes us to be able every year on the same date, see the same stars?

• it spins

• it rotates

• it orbits/revolves
