The planet…What do we know?The planet…What do we know?

• All the planets in our solar system revolve around the sun.

• But how?

Page 8: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• The Earth rotates on its axis • 1 full rotation = one day

• Looking at the picture below, why is the left hemisphere experiencing a warm day and the right hemisphere experiencing a cooler night?

DAYwarmer

NIGHTcooler

Comparing Rotations:

Earth=24 hrs

Mercury=59 days

Pluto=6 days

The Earth orbits (revolves around) the sun

How long is one full revolution? 365 days

=

1 year

Comparing Revolutions:

Earth=365.25 days

Mercury=88 days

Oluto=248 years

• So this is what the Earth looks like right?axis

Page 11: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• And it revolves around the sun like this right?

This shows orbit

This shows orbit

WRONG!

Page 13: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• Earth’s axis is not straight– Earth’s axis is tilted 23.5° from

• Why does that matter?The Earth’s tilted axis allows us to

have seasons• 4 seasons based on Earth’s position to the sun

Winter

• So what does this look like for us, in the Northern Hemisphere?? For each part of the

demo, fill out your chart based on what is represented by each specific location:1)tilt (towards/away)2)Radiation (high/neutral/low)3)Temperature (warm/moderate/cold)4)Season

• The star "Lucy" in constellation Centaurus is actually a huge cosmic diamond of 10 billion trillion trillion carats.

Page 21: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• Winter• When the Earth is tilted away from the

sun.• Coldest temperatures

Top tilted away from

sun= winter

Page 22: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• Spring• Moderate

(medium) temperatures

• Starts cold and gets warmer as that part of Earth is tilted toward the sun

Beginning to be tilted

toward the sun= spring

Page 23: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• Summer• When the Earth is titled toward

the sun.• Warmest temperatures

Top titled toward the

sun= summer

Page 24: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

Autumn (fall)• Moderate

(medium) temperatures

• Starts warm and gets cooler as that part of Earth is tilted away from the sun

Beginning to be tilted

away from the sun=

spring

Page 25: Warm-Up (in your JOURNAL) 1.During which months do you think the following pictures were taken? (A)(B) 2.Where does almost all the heat on Earth come from?

• The equator divides the earth into top and bottom halves (Northern and Southern hemisphere)

• Because of the tilt of the earth, the hemispheres have opposite seasons.

WHY?

POSTCARDPOSTCARD• Pick a place on the map you will travel to

over the summer.• Write a postcard telling your friend what

season it is there. Explain why it is that season. Describe what the temperature is like.

• For the picture on your postcard (on the back), draw what the Earth and sun would look like for this season.
