UPDATE: Resources for studying

And say thanks to Hilda for the next one: check your answers that you wrote for your review.

Week 10, Day 1

PTT:
1) Go into PowerSchool
2) Check to see if you have an NHI for Lab Reflection/Refraction & Mirror Maze Questions
3) If you do, you should have the 2 documents for these labs (from last Monday) saved on your computer. Upload both of them (with questions and charts completed, as needed) to google drive.

Task 1:
1) Turn to page 127 in your notebook
2) Check to see that you have completed all 4 boxes using the following online textbook using page 444 and 450-451
box 1: diagram of light coming into eye with image projected upside down on back of eye;

box 2: paragraph about how our eye and brain help us see images;
box 3: diagram of normal, nearsighted, and farsighted eyes;

box 4: diagram of lenses used to fix nearsighted and farsighted eyes



3) If done page 127, remind yourself of our last science class: did you completed the task 5 diagrams from the wiki and hand them in on a blank piece of paper?

1. Concave lens with light and image passing through
2. Convex lens with light and image passing through
3. Human Eye with normal (20/20) vision
4. Human eye with nearsightedness (focuses before retina)
5. Human eye with farsightedness (focuses behind retina)
6. Human eye with nearsightedness and corrective lens to fix it
7. Human eye with farsightedness and corrective lens to fix it

Task 2:
1) Open up a blank document in word, pages, or google docs (your choice)
2) Copy and paste the following questions into the document. You will be answering these with written answers, diagrams, and/or images to help you study for the Waves and Light test on Thursday (periods 1 and 2) and Friday (period 6). Make sure you answer EVERY question for each topic. This document will be quite helpful as you answer questions:
- Waves:
What are the parts of a wave?
Be able to label all parts correctly (amplitude, crest, resting position, trough, wavelength)
- Electromagnetic spectrum:
What are the 7 types of electromagnetic radiation from longest to shortest?
What is 1 use for each type of wave?
How much of it can people see?
What does wavelength of visible light have to do with color?
- Transmission:
What is it?
When does it happen?
Does light transmit fully through transparent, translucent, or opaque objects?
- Reflection:
What is it?
When does it happen?
- Law of Reflection:
What is it?
Be able to label all parts of a "angle of reflection" diagram.
Be able to complete a reflection diagram and calculate the angles.
- Scattering:
Why is scattering also called diffuse reflection?
When does it happen?
- Absorption:
What is it?
When does it happen?
- Refraction:
What is it?
When does it happen?
What does the speed of light have to do with refraction?
What happens when an object has a higher index of refraction?
- Transparent, translucent, opaque:
What is the difference between each of these types of object?
What happens when light hits each of these types of object?
- Color:
Why do objects appear to be the color they are?
What color of light will be reflected from a red object?
What happens if a red light is shined on a blue ball?
- Lenses:
Does light converge (come to a focal point) or diverge (spread apart) when it goes through a convex lens?
Does light converge (come to a focal point) or diverge (spread apart) when it goes through a concave lens?
Draw or copy/paste a diagram of each.
Describe the shape of a convex lens.
Describe the shape of a concave lens.
- Lenses and the Human Eye:
What happens to an image when it goes through the eye? Draw a diagram to help you.
Why is an image upside down on your retina?
Draw an image of light going through a nearsighted eye.
Draw an image of light going through a farsighted eye.
What type of lens fixes nearsightedness?
What type of lens fixes farsightedness?
- Mirrors:
Draw a convex and concave mirror.
Draw what happens when light reflects off of these two types of mirrors.
