Tuesday, January 19 th Entry Task Sing the EM spectrum song in your head. 1.List the parts of it from lowest frequency to highest frequency. 2.Put a circle around the part that has the lowest frequency 3.Put a square around the part that has the shortest wavelength 4.Put a triangle around the part that you can detect without any tools Schedule: 17.3 Notes Homework: Read/RSG 17.3 Objective: I can understand that the sun is the source of most visible light Please have on your desk EM Waves Book

Visible Light Notes Sun (Natural Light) –Uses Nuclear Reactions to create Electromagnetic Energy (All Kinds)

Incandescent –Uses electricity to create heat, which creates light Visible Light Notes

Fluorescent –Uses electricity to create U.V. light, U.V. light reacts with chemicals to produce visible light

Visible Light Notes Bioluminescent –Uses chemicals reactions inside animals to produce light

Fluorescent LightSunlight Incandescent Light

17.3 Questions 1.How is plants’ use of light important to animals? 2.Why does little light reach earth from stars other than the sun? 3.How is bioluminescence different from incandescence? 4.What causes ordinary light bulbs to burn out? 5.What is the function of the phosphor in a fluorescent light bulb? 6.What is the function of the mercury vapor in a fluorescent light bulb? 7.What is the function of the current in a fluorescent light bulb 8.Why are fluorescent lights more efficient than incandescent lights? 9.What are the working elements of an incandescent bulb? 10.Does LED have these elements? If not what does it have instead? 11.Compare heat, efficiency, and longevity of a LED and incandescent light bulb.

Wednesday, January 20 th Entry Task Write down the colors of the visible light spectrum in order with the shortest wavelength first going to the longest wavelength Schedule: Bill Nye- Light and Color Homework: 17.4 Read/RSG Objective: I can understand important information about light and color Please have on desk: 17.3 RSG

Thursday, January 21 st Entry Task Be ready to be randomly called on to present your project. You may want to write this down: You need to talk through the presentation narrating what is going on. You then need to “see inside” your project and pick 3 codes to explain. You will discuss their purpose and what the different parts of the code do. Schedule: Project Presentation Homework: None Objective: I can present my final Scratch project to the class. I can explain the science and the code.

Friday, January 22 nd Entry Task Answer the following questions using full sentences, IQIA. 1.How does the wave behavior of light affect what we see? 2.Give an example of how light waves interact with materials 3.Why do objects have color? 4.How are different colors produced? Schedule: Light notes Homework 17.4 Questions Objective: I can understand that light waves interact with materials. Please have on desk: 17.4 RSG

What is ROYGBIV? Color…How it works

ROYGBIV is the Visible Light Spectrum. Each letter in ROYGBIV represents a different part of the spectrum. Each part of the spectrum has a different Wavelength and Frequency. R= Red (Longest W.L) O = Orange Y = YellowG = Green B = BlueI = Indigo V = Violet (Shortest W.L) Color…How it works

Color is a result of which wavelengths of visible light are reflected, and which are absorbed

Color…How it works The water in the bucket looks blue because the red, orange, yellow, green, indigo and violet parts of visible light are being absorbed by the water, but the blue part of visible light is being reflected back to your eye.

Draw a Picture Draw a picture of Mrs. Guttormsen’s Sweater. Show the wavelengths of light that would be reflected and those that would be absorbed. Draw another picture but of Mrs. Guttormsen’s dress. Show the wavelengths of light that would be reflected and those that would be absorbed.

Primary and Secondary Colors of Light Primary colors are those that can make all other colors Primary light colors = Red, Green Blue Red, Green and Blue mixed, in equal parts, make white light

Primary colors of Light Combinations of Red (R), Green (G) and Blue (B) Light can make secondary colors of Yellow (R + G); Cyan (G + B) and Magenta (R + B) Any mixes of secondary colors make white light

Primary and Secondary Colors of Pigments Primary colors of pigments (like dyes in paint) are Cyan (C), Magenta (M) and Yellow (Y) Cyan (C), Magenta (M) and Yellow (Y) mixed in equal parts make black.

Secondary colors of pigments are made by mixing the Primary colors. (C + M = Blue); (M + Y = Red); (C + Y = G) Any mixes of Secondary colors together make black Primary and Secondary Colors of Pigments
