8. Announcements Make-up work Grades updated: 3rd quarter finished
Journals, tests, quizzes
Grades updated: 3rd quarter finished
4th quarter grading starts NOW
Homework & Journal
CGA May 27-28
Ticket exchange Thursday / Friday!
Classroom procedures
Heads down/ sleeping/ off-topic conversations

9. 8 minutes
DO NOW
Draw the wave above and label: wavelength, amplitude, crest, trough
Draw two waves: one with high frequency and one with low frequency
Draw two waves: one with high amplitude and one with low amplitude
Draw one wave with high frequency and low amplitude
Draw one wave with long wavelength and low amplitude

10. The entire range of electromagnetic waves, including all possible frequencies, is called the electromagnetic spectrum.
Frequency = energy
Shorter the wavelength, higher the energy
Notice the order of colors of visible light
Which color has the most energy
Which color has the least energy

11. 10 minutes Think, write, share
With your group mates, discuss and determine the following:
Be prepared to share out for “Electromagnetic spectrum worksheet” grade
I will call on random people to answer – this is a group/activity grade

13. Expectations for notes
C – None; unless directed
H – raise hand
A – light and sound notes
M – None unless given permission
P – taking notes, asking questions, no heads down, no sleeping
S – 4th quarter success!

14. sound

15. Frequency and Pitch
The pitch of a sound is how you hear and interpret its frequency.
A low-frequency sound has a low pitch.
A high-frequency sound has a high pitch.
Each person is saying “Hello”.

16. The speed of sound
The speed of sound in normal air is 343 meters per second (660 miles per hour).
Sound travels through most liquids and solids faster than through air.

17. 24.1 The speed of sound
Objects that move faster than sound are called supersonic.
If you were on the ground watching a supersonic plane fly toward you, there would be silence.
The sound would be behind the plane, racing to catch up.
Example of "Sonic Boom“
 F14 Tomcat

18. Music that is school appropriate
The Doppler effect
When the object is moving, the frequency will not be the same to all listeners.
The shift in frequency caused by motion is called the Doppler effect.
You hear the Doppler effect when you hear a police or fire siren coming toward you (gradually louder), then going away from you (gradually softer).
1 volunteer needed
Must have:
Cell phone
Music that is school appropriate

20. The wavelength of sound
Wavelength is also important to sound.
Musical instruments use the wavelength of a sound to create different frequencies.

21. Pitch  Frequency

22. Loudness  Amplitude

23. light

24. Properties of light
Light travels fast over long distances and carries energy and information.
Light travels in straight lines, but can be bent by lenses or reflected by mirrors heat and warmth.
Light has color and can be bright or dim.

25. The electromagnetic spectrum
Light, like sound and heat, is a form of energy.
The visible light we see is part of the electromagnetic spectrum.

26. Properties of light
You see book pages because light in the room reflects from the page to your eyes.
Your eyes and brain use the information carried by the light to make a mental picture.

27. Color and energy Need 3 volunteers
When all the colors of the rainbow are combined, we see light without any color.
We call the combination of all colors white light.
Need 3 volunteers

28. Color and energy
Compare the hot, blue flame from a gas stove to the orange flame of a match.
Which has higher energy?
* Think back to the electromagnetic spectrum

29. Color and energy
The light from a gas flame is blue (high energy) and the light from a match is red-orange (low energy).

30. 25.1 The speed of light
The speed at which light travels through air is about 300 million meters per second.
NOTHING IS FASTER THAN THE SPEED OF LIGHT!!

31. 25.1 Wavelength and Frequency of Light

32. Wavelength and Frequency of Visible Light

33. Labs! We will be conducting labs this class and next class
If you are unable to conduct yourself in an appropriate way beneficial to the learning environment, you will be sent to 207 (Hunter) or 308 (Dean) to complete an alternative assignment
Conduct for walking through the halls (classroom consequences):
Do not bang on walls
Do not disappear to use the bathroom without permission
Stay with the group if you are lagging behind I will send you back
Do not disturb other teachers classrooms
