Patterns of Earth and Sky Lesson 1.1-1.3

Patterns of Earth and Sky Lesson 1.1-1.2

Today I will learn

• That earth is a sphere.

• what stars are and where they are located

• What astronomers and archeologist are

• What stars are in our solar system

• What a solar system is

Do now: What ideas come to mind or do you have about this unit?

• What ideas do you have about the stars?

• What questions do you have about the stars

An astronomer is a scientist who studies stars, planets, and other objects in the universe, but not Earth. 

Archaeologists are scientists who study people from long ago and their activities. They do this by studying their tools, pottery, statues, paintings, and other things they made or built.

Multiple Choice

True or false, an astronomer studies things on earth

• true

• false

In this unit, you will be doing an investigation to determine the missing part of this artifact

Investigation begins

• What do we see in the night sky vs the sky during the day?

• What in the artifact might you see in the sky?

• Where are the stars in space?

Did you know...

Our galaxy is called the Milky way

Stars are all different distances away

So stars are located all around us in space

The sun is the only star in our solar system

Why is Betelgeuse the largest star on this list but we see the sun much bigger in our sky?

Multiple Choice

Why is Betelgeuse the largest star on this list but we see the sun much bigger in our sky?

• because the sun is actually the biggest star

• because the sun is the brightest star

• because the sun is the closest star to earth

• I have no idea

Galaxy versus Solar System

• A solar system is a specific kind of system in which the Sun is at the center.

• The solar system includes the sun, the planets that orbit the sun, and any other object that orbits the sun

• A galaxy, such as our Milky Way Galaxy, is a group of solar systems orbiting around a black hole

• Orbit: a circular path a space object makes around a star, moon or planet.

• The Earth orbits the sun

Let's explore two SIMulations today

Earth SIM and A scale tool

Scale tool

• What is the scale tool showing?

• Are the objects getting smaller or bigger

• What was the biggest object shown in the video?
