Week 5, Day 2


PTT:
1) Turn to page 112 in your science notebook (p. 111 will be used to staple our Electricity Test to)
2) Record the date in the top corner: W5, D2
3) Record the title: Introduction to Light and Waves
4) Record the goal - Goal: I can explain what a "wave" is.
5) Divide the page into 4 boxes.

Task 1:
1) Title box 1: Light
2) Draw an image that represents what you think light is (take up about half of the box).
3) Which of the ways of picturing light did this match with? Did you draw a RAY or a WAVE?
4) Label the picture as RAY or WAVE.
5) Now use a different color to draw a picture that represents the other way to portray light. Label the picture as a RAY or a WAVE.

Light WAVES



Task 2:
1) Title box 2: What is a Wave?
2) Watch the video of one of the greatest scientists of all time - Richard Feynman - explain "waves."

Try this these instructions to add to the overall feel of his explaination.
2-1. Open this video, pause at beginning ready to play.
2-2. In another window, open Best of BBC Planet Earth HD [ Kamil Bartolewski - Morning Sun ]. Cue ready to play with sound off.
2-3. In a third window, open "Apparat Not a number" with sound on half level.
2-4. Play all videos, open BBC planet earth video on HD fullscreen.
Enjoy!
3) Wikipedia says: "In physics a wave is a disturbance/oscillation that travels through spacetime, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with little or no permanent movement of the particles of the medium." (Wikipedia)
In simpler terms, a wave is a disturbance that travels through space-time while transferring energy. Waves transfer energy through matter without moving the matter from one place to another.
- Using your own words and these two definitions, record a definition for "wave" in box 2. Be sure to highlight the word when you are done.

NOTE:
There are 2 types of waves:
  1. Mechanical waves
  2. Electromagnetic waves

Task 3:
1) Title box 3: Mechanical Waves
2) Read the following: Mechanical waves travel through a medium (solid, liquid, gas), causing the particles of the medium to collide and smash into each other. For example, sound waves (music) use air molecules to travel through causing the air molecules to smash into their neighbors like people in a mosh pit at a punk concert. When these air molecules collide with each other they bounce off one another keeping them from traveling in the direction of the wave.
3) Watch the extreme amount of energy generated by this mechanical wave. Even more, watch this guys break the world record for largest wave ever surfed. People are amazing!!

4) In your own words, record a definition for mechanical waves and draw an image that represents it. Make sure to highlight the word when you are done.

Task 4:
1) Title box 4: Electromagnetic Waves
2) Read the following:
Electromagnetic waves do not need a medium (solid, liquid, gas) to travel through. Instead, they consist of waves generated by charged particles within an electrical and magnetic feild. These types of waves vary in wavelength and include radio waves,microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
3) Record a definition for electromagnetic waves. Make sure to highlight the word when you are done. Draw a few pictures to represent the different kinds of electromagnetic waves.

Homework:
Finish your electricity review assignment and study for the electricity test.


Week 5, Day 3


PTT:
1) Open your notebook to p. 112
2) Did you finish the page?
3) If you didn't, you'll need to finish the page:
Box 2:
Wikipedia says: "In physics a wave is a disturbance/oscillation that travels through spacetime, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with little or no permanent movement of the particles of the medium." (Wikipedia)
In simpler terms, a wave is a disturbance that travels through space-time while transferring energy. Waves transfer energy through matter without moving the matter from one place to another.
- Using your own words and these two definitions, record a definition for "wave" in box 2. Be sure to highlight the word when you are done. Draw an image of the rope demo in the box.
Box 3
- Title box 3: Mechanical Waves
- Read the following: Mechanical waves travel through a medium (solid, liquid, gas), causing the particles of the medium to collide and smash into each other. For example, sound waves (music) use air molecules to travel through causing the air molecules to smash into their neighbors like people in a mosh pit at a punk concert. When these air molecules collide with each other they bounce off one another keeping them from traveling in the direction of the wave.
- Copy down the definition that is in blue. Highlight the term when you're done. Draw an image that represents a mechanical wave.
Box 4:
1) Title box 4: Electromagnetic Waves
2) Read the following:
Electromagnetic waves do not need a medium (solid, liquid, gas) to travel through. Instead, they consist of waves generated by charged particles within an electrical and magnetic feild. These types of waves vary in wavelength and include radio waves,microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
3) Record a definition for electromagnetic waves. Make sure to highlight the word when you are done. Draw a few pictures to represent the different kinds of electromagnetic waves.

Task 1:
1) Do "the wave" as part of the class.
2) Discuss: what was moving? How were the people moving? Did they move permanently?

Task 2:
1) Turn to page 113 in your notebook
2) Title it: Waves on a String
3) Record the date: W5, D3
4) Record the goal - Goal: I can describe the fundamental properties of waves.
5) Click on the link to access the activity: Waves on a String
6) Complete the worksheet as you do the activity

Task 3:
1) Turn to p. 114
2) Title it: Waves Diagram
3) Record the date: W5, D3
4) Record the goal - Goal: I can accurately diagram a wave
