Warm Ups
Warm Up 1- Lab
In the lab, we looked at different types of electromagnetic energy.
The purpose of the lab was to experience different types of electromagnetic energy and learn about it.
The main result of the lab was when you looked at a particular color of light through the spectroscope, you saw mainly that color on the side. Also, when we exposed the white beads to UV rays, they turned purple.
I am still uncertain of how this relates to the universe.
I learned that:
1. White light has all the colors.
2. Gamma rays are very harmful.

Warm Up 2- Electromagnetic Energy
Red light is different from blue light because red light has a longer wavelength and blue light has a shorter wavelength.
Astronomers use radio waves to find the distance to far away celestial bodies. They also use visible light to find out what a star is made of. They use visible light to tell whether an object is coming towards earth or going away.

Warm Up 3- Lab
In the lab, we examined energy waves.
The purpose of the lab was to look at wavelength and examine what makes colors different from each other.
When you moved your finger from one side to another, the waves bunched up and the they became smaller while the waves behind spread out and became slower. This represent that if la light is traveling in a straight path, the light in front of it would have a higher frequency and the light behind it would have a lower frequency.
Is there a type of light that travels in a straight line?
1. Wave lengths determine color.
2. Most galaxies are moving away from us.

Warm Up 4- Red Shift
The red shift is when electromagnetic energy is traveling away from an object. The objects waves get further apart and the color turns red.
The red shift supports the big bang theory because the universe is still expanding.
Astronomers use radio waves to tell how far away an object is from earth and if it is getting closer or farther.

Warm Up 5- Astronomy
- Over the holiday, I spent my time traveling from the couch to the fridge then back to the couch again.
- Astronomers use radio waves to locate objects in space. They use visible light to find out what a star is made of. Also, they use visible light rays to see if a galaxy or celestial bodies are moving toward us or away from us.
- The Big Bang Theory is the theory that the universe came from a densely packed mass that expanded and became our universe and is still expanding today. This theory is supported by the red shift.

Warm Up 6- Light year
A light year is unit of measurement that astronomers use to measure distance in space. It is the distance light travels in a year. They use light years because distances in space are so great that regular miles or kilometers would be too small.

Warm Up 7- Galaxies
Astronomers classify galaxies into three categories by their shapes:
-Spiral
-Elliptical
-Irregular

Warm Up 8- Universe
Nebulae are clouds of dust that can be lightyears long. They are basically a birth ground for stars. They are mostly made up of hydrogen just like stars themselves.
-Stars are formed from nebulae.
-After a star dies, it can create a black hole.
