Study Hall: Sit in assigned seats, working on something quietly. Get out your new interactive notebook!

Warm Up - 2 minutes Write: November 12 & complete Warm Up by answering the ? You are sitting outside in the sun….. 1. Do you think the sun is giving off energy? How do you know?

Share with the Class? Volunteers? You can feel the heat from the sun (infrared) You can see different colors (visible light) Your skin can absorb the sun’s rays (ultraviolet)

Interactive Notebook Q2 Quarter 2: New notebook & new table of contents Label 1 st page in new notebook: Quarter 2 Table of Contents Add 1 st entry: Electromagnetic Spectrum Number this entry: page 1

Interactive Notebook Q2 Skip 4 pages (this if for table of contents) Label Page: Electromagnetic Spectrum 6.P.3.2 Number page 1 at the top of the page Circle the number

Discovery Ed video “Energy from the Sun” (stop at 2 minute mark)

Sun’s Energy Write these notes: The Sun: – a major energy source for Earth – energy reaches the Earth through process of radiation

Write these notes…. These waves have different wavelengths, frequencies and amounts of energy These waves of energy make up the electromagnetic spectrum.

Write these notes: Light and electromagnetic waves WARM objects.

Write these notes: An objects temperature increases depending on: how intense the light striking the surface is, how long the light shines on the object, how much of the light is absorbed.

Electromagnetic Spectrum

Electromagnetic Spectrum FOLDABLE for your notebook!

Electromagnetic Spectrum Foldable Add this statement to your foldable to help you remember the parts Roxy May Is Victorious Using X-box and GameCube

Write these notes on the arrow Wavelength is increasing from RIGHT to LEFT (Gamma to Radio)

Write these notes on the arrow Energy is increasing from LEFT to RIGHT (Radio to Gamma) Frequency is increasing from LEFT to RIGHT (Radio to Gamma)

Take notes on your foldable Turn your foldable sideways and write this information:

Radio Write the notes for radio waves: have low energy have low frequency have the longest wavelength (can be as BIG as buildings) carry signals for radios, TVs, and cell phones

Microwave Write these notes for microwaves: Used for heating our food communication forecasting the weather directing planes at airports Wavelength = size of a honey bee

Infrared Write these notes for infrared: Used for heating Thermal imaging and Satellite imaging (weather) Operating remote controls Wavelength = size of a pinhead

Discovery Ed video “Heat is Everywhere”

Visible Light Write these notes: Only waves we can see ROY G. BIV (colors, rainbow) Red = longest wavelength Violet = shortest wavelength Wavelength = a microscopic substance (protozoan)

Ultraviolet Write these notes: Can cause sunburns Most waves blocked by ozone Weather reports use UV index (1-10) Used in tanning beds Wavelength = size of molecules

X-Ray Write these notes for x-rays: Allows doctors to view bones Too much exposure is harmful Wavelength = size of atoms

Gamma Write these notes for Gamma: Highest energy and most dangerous From radioactive atoms and nuclear explosions. Used in medicine: kills cancer cells but also healthy cells (hair falls out) Hiroshima, Japan: atomic bomb dropped (caused people and buildings to instantly melt and birth defects over time)

Glue foldable in notebook. Add the foldable to the next available page, number the page, circle the page number, and add to your table of contents
