Recall: We looked at different colored light bulbs when they were turned on through a spectroscope to see different colored lights. Then we took beads that change color when exposed to UV rays outside into the sun and they changed color.
Explain: We learned about different kinds of electromagnetic rays.
Results: The results were the beads changed colors. There were different colored lights when we looked through the spectroscope
Uncertain: Are there any other kinds of electromagnetic energy.
New: I learned about spectroscopes and how to use them. I also learned that x-rays were a kind of electromagnetic energy notes.

- Red light has a longer wave length and blue light has a shorter wave length.
- They use it to determine if galaxies are moving are moving towards the Earth. They use it to classify which category stars are in.

Recall: We used waves in water to demonstrate how light moves
Explain: When we created waves near the wall of the bowl, the waves stopped at the wall. The waves were longer on the other side of the finger where there was nothing blocking the waves.
Results: The results were that the waves in the water changed length as the finger moved toward one end of the bowl
Uncertain: We don't know how this pertains to space.
New: I learned that light waves change colors the longer or shorter the waves are.

- A red shift is when light waves are moving farther away and it leaves red light.
- The red shift supports the Big Bang theory.
- Astronomers use Radio waves to predict how far away planets and other celestial bodies are from each other.

- Astronomers use electromagnetic energy to classify stars.
- The Big Bang Theory is that theory that the universe was created from a single particle of energy that exploded causing planets and celestial bodies to form. They are constantly drifting away from a central point. Red shift supports the Big Bang Theory.

A light year is the distance light travels in a year. It is a unit of distance. Astronomers use light years to determine length and distance between points in space because space is really big and it is easier to work with a smaller number.

Astronomers classify galaxies by their shapes.

- Nebulae are big clouds of gases inside a galaxy They are the biggest things in the Galaxies.
- Stars are the brightest and most abundant things in the visible universe. Also they do not twinkle like everyone believe they do.
