Classwork #3: Sound
Slide 20 / 59
13 The ________________ around you is
- ccupied by very small objects that we call
- particles. You can’t see them because they’re too
small.
Slide 21 / 59
14 A ________________ moves through the air through a series of collisions.
Slide 22 / 59
15 Compare and contrast the motion of particles in a transverse wave and a longitudinal wave.
Slide 23 / 59
16 True or False: Sound is an example of a transverse wave.
A True B False
Slide 24 / 59
Homework: Sound
SLIDE 5
Slide 25 / 59
17 True or False: Higher pitched sounds are always louder then lower pitched sounds.
A True B False
Slide 26 / 59
18 Can sound move in outer space? Support your argument with some facts you know about space and longitudinal waves.
Slide 27 / 59
Classwork #4: Sight
Slide 28 / 59
19 We need ________________ in order to see.
Slide 29 / 59
20 So far, we learned that three things could happen to light, it can either be absorbed, bent, or ________________.
Slide 30 / 59
21 The sun and other light sources give off ________________ of light. They will continue on in straight paths until they collide with something else.

Slide 31 / 59
Homework: Sight
Slide 32 / 59
22 Why can’t we see in the dark?
Slide 33 / 59
23 True or False: We can see an object because after the light hits the object it is reflected back to our eyes.
A True B False
Slide 34 / 59
Classwork #5: Color
Slide 35 / 59
24 What colors do you get after passing a beam of white light through a prism?
Slide 36 / 59
25 True or False: All of the colors are contained within a beam of white light.
A True B False
SLIDE 7
Slide 37 / 59
26 True or False: The color we see is the color that is absorbed by the object.
A True B False
Slide 38 / 59
Homework: Color
Slide 39 / 59
27 The color that we see is ________________ off the
- bject; this is why we see that color instead of all
the other colors.
Slide 40 / 59
28 A box appears red because it ________________ the color red and ________________ the rest of the other colors.
Slide 41 / 59
29 If nothing is reflected off the surface of the object what color do you see?
Slide 42 / 59
Classwork #6: Mirrors
SLIDE 8
Slide 43 / 59
30 True or False: Light reflected off the surface of a mirror will go off at a different angle then the one it hit the mirror.
A True B False
Slide 44 / 59
31 If an object is located 5 meters in front of a plane mirror, how far will the image appear behind the mirror?
Slide 45 / 59
Homework: Mirrors
Slide 46 / 59
32
Which path will the beam of light take after hitting the mirror or mirrors? (The colors for the paths are just meant to make it easier to see the different paths of light, we are not asking anything about color here!) A path 1 B path 2 C path 3
Slide 47 / 59
Classwork #7: Refraction
Slide 48 / 59
33 Describe what you see when you place an object like a ruler or pencil into a glass of water.
SLIDE 9
Slide 49 / 59
Homework: Refraction
Slide 50 / 59
34 Why does the ruler or object placed in the water appear to be bent?
Slide 51 / 59
35 What do we call the bending of light when it happens from moving from one material into another?
Slide 52 / 59
