Start the following in class:
1. Sign onto your Google classroom. Under the topic of Atomic Structure, follow the instructions for “How did atomic theory develop from historic times to 1932?”
2. The required focus journal questions J40A for today are:
a. Which color of visible light has the most energy per photon, red, orange, yellow, green, blue, indigo, or violet?[FYI, to an approximation: violet = 400 nm, indigo = 460 nm, blue = 480 nm, cyan = 490 nm, green = 540 nm, yellowish-green = 560 nm, yellow = 580 nm, orange = 610 nm, red = 650 to 750 nm].
b. How do you know that what you assert about the energy of the photons does indeed describe reality? Use examples to clarify each idea that you express in your journal and make explain how each example demonstrates the concept being considered.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Take Cornell notes on the first two pages of the document entitled Understandings Leading To The Electron Cloud Model.
2. The blue light component in the white light being emitted from LED computer monitor displays is not good for the eyes. To be kind to your eyes with a manual mode 3400 K color temperature and an 80% brightness intensity without pulse width modulation flicker, install free Iris mini software for computer installations after clicking here.
Not available in 2019:
1. Centered on the first blue line of the next page in your Journal notebook, write Video Assignment. Write J40B to the left of the red marginal line. For Journal 40A read the following questions first, then view the video on Color (28:42) and record Cornell notes in full sentences that answer the questions.
a. How did the discovery of how to make the first artificial dye occur?
b. What was the impact of this discovery on the development of chemistry?
c. According to the film’s writers, which country was impacted the most by this discovery? Why was this country able to be so impacted?
d. What are some applications of color in chemistry?
