2. Chemistry Do Now
Directions: Take out a sheet of notebook (Do Now sheet) and set it up as instructed. Answer the following questions. (5 minutes)
Give 1 piece of evidence that supports the Big Bang Theory.
What happened to the black dots you drew on your balloon yesterday as you continued to blow up the balloon?
What does ROYGBIV stand for?
Put the colors of the visible light (ROYGBIV) in order from the least energy to the most energy.

3. Chemistry Do Now Key
Give 1 piece of evidence that supports the Big Bang Theory. There are more than 1 answer to this question. Sample answer: The universe is still expanding.
What happened to the black dots you drew on your balloon yesterday as you continued to blow up the balloon? They moved away from each other.
What does ROYGBIV stand for? Red, Orange, Yellow, Green, Blue, Indigo and Violet
Put the colors of the visible light (ROYGBIV) in order from the least energy to the most energy. Red, Orange, Yellow, Green, Blue, Indigo and Violet

4. Objectives
Students will know the visible light spectrum, how it is used to determine distances in space and how to determine whether an object is moving towards or away from Earth by taking notes, reading an article and creating a color wheel.
Mastery Level: 75% or better

9. Prepare to take notes on the formation of the universe

10. The Electromagnetic Spectrum

11. The Electromagnetic Spectrum
longest wavelength
shortest wavelength
The Electromagnetic Spectrum
The name given to a group of energy waves that are mostly invisible and can travel through empty space
Shorter waves have more energy and longer waves have less energy

12. Characteristics of Visible light:
longest wavelength
shortest wavelength
Characteristics of Visible light:
Shorter wavelength than infrared waves.
Can be seen as colors.
Half of Sun’s rays are visible light.

13. REDSHIFT & BLUESHIFT

14. What Are Redshift and Blueshift. By Elizabeth Howell, Space
What Are Redshift and Blueshift? By Elizabeth Howell, Space.com Contributor | March 16, 2018
The visible light spectrum.
Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion.
Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter.

15. How do we see color? The absorption of all colors creates BLACK.
The reflection of all colors creates WHITE.

16. Extension - Exit Ticket Color wheel activity to demonstrate the reflection of all color.
