NGSS.HS-ESS1-2

Elongated radiation observed in all directions in space. Left over from the early (hotter, denser) universe. Provides evidence that the universe has expanded and cooled.

• Nuclear Fusion

• Blue Shifted Galaxies

• Luminosity

• Cosmic Microwave Background

NGSS.HS-ESS1-2

Phenomenon where the wavelength of light from distant galaxies indicates that they are moving away from us.

• red shift

• blue shift

• Nuclear Fusion

• Big Bang Theory

NGSS.HS-ESS1-2

Cluster of 100 billion stars or more. Ours is called the Milky Way.

• Solar System

• Galaxy

• Universe

• Black Hole

NGSS.MS-ESS1-2

The process by which light elements combine to form heavier elements, and some mass is converted into energy. Happens in the (very hot) cores of stars.

• Red Shift

• Cosmic Background Radiation

• Nuclear Fusion

• Constellation

NGSS.HS-ESS1-3

NGSS.HS-PS1-8

A star's brightness. It's mostly dependent on size. Larger = brighter.

• Nuclear Fusion

• Gravity

• Temperature

• Luminosity

A group of stars that form a pattern. Visible ones change throughout the year because we get a changing view of space as we orbit the sun. Circumpolar ones are visible all year and appear to orbit Polaris. They don't - we're rotating.

• Luminosity

• Constellation

• Galaxy

• Nuclear Fusion

The early stage of star, when it is stably fusing Hydrogen into Helium. Our sun is in this stage.

• Red Giant Stage

• White Dwarf Stage

• Nebula

• Main Sequence Stage

Intermediate stage of a sun-like star. Hydrogen has run out and heavier elements (Helium, Carbon and Oxygen) are being fused in its core, causing it to expand and cool.

• white dwarf stage

• red giant stage

• main sequence stage

• nebula
