STARS Adapted for TCSS

S4E1 Students will compare and contrast the physical attributes of stars, star patterns, and planets. a. Recognize the physical attributes of stars in the night sky such as number, size, color, and patterns.

How do stars compare in terms of size, color, brightness, and patterns? EQ:

What is a star? A star is a huge ball of very hot gases like hydrogen and helium.

Our sun is the closest star to our planet. It is the only star in our solar system.

Scientist classify stars in several ways: By size By color By brightness

Star Sizes Stars come in different sizes. Some stars are even smaller than Earth. The smallest stars are called neutron stars.

STARS Star Size (biggest to smallest) Star Size (biggest to smallest) 1. Super Giants (biggest) 1. Super Giants (biggest) 2. Giants 2. Giants 3. Medium Sized 3. Medium Sized

Star Colors: color tells the temperature Red (coolest) Red - orange Yellow White Blue (hottest)

STARS Star Temperature (coolest to hottest) Star Temperature (coolest to hottest) Related to color Related to colorRedRed-OrangeYellowWhiteBlue Coolest Hottest

Star Brightness Brightness depends on two things: How far it is from Earth. How bright it actually is.

STARS Star Brightness Star Brightness Depends actual brightness of the star and distance from earth Depends actual brightness of the star and distance from earth

STARS Star Patterns Star Patterns (A pattern or group of stars in the sky is called a constellation.) Big Dipper

STARS Star Patterns Star Patterns Orion is one of the brightest constellations and is a mythological character.

What is our Sun? Medium size Medium heat A yellow star Medium brightness
