Our galaxy! The Sun is located on one of the arms of this spiral galaxy. It has an estimated 100 billion stars and is about 100,000 light-years across. It takes our solar system 250 million years to complete one revolution around the center of the Milky Way. It is 13.5 billion years old. More information here.
The Earth is about 26,000 light-years to the center of the Milky Way.
The most inspiring naked-eye object in the sky is our own galaxy, the Milky Way. This mosaic of photographs taken in Germany and Namibia shows some of the billions of stars that make up our neighborhood, along with reddish clouds of hydrogen gas and a dark obscuring lane of interstellar dust.

Add the definitions in your foldable (you can summarize in your own words)
The Main Sequence is where stars spend most of their lives.
A "low mass star" is a star with significantly less mass than the Sun, typically considered to be less than about 2 solar masses. They are cool and dim, but live longer lives.
A "high mass star" is a star with a much greater mass than the Sun, generally considered to be 8 times the mass of the Sun or more. They are hot and bright but live short lives.

Low Mass and High Mass Star Graphs
Low Mass and High Mass Star Graphs
Go to “Star in a Box” https://starinabox.lco.global/ you will start with a low mass star (the sun).
Draw the Main Sequence for the sun.
Then draw the yellow path of a low mass star and a high mass star.
Plot the significant points along your path, when the star enters a new STAGE, label this on your graph.
Repeat 1-4 for a high mass star 40x the size of the sun.
