DAY 74

#Goals:

SWBAT...

1. ...correctly answer 80% of the review questions

Warm-Up

1. Which of the following statements is true about power?

a. power is a time-based quantity

b. power refers to how fast work is done upon an object

c. powerful people or powerful machines are simply people or machines which always do a lot of work

d. a force is exerted on an object to move it at a constant speed. The power delivered by this force is the magnitude of the force, multiplied by the speed of the object

e. the standard metric unit of power is the Watt

f. if person A and person B do the same job, but person B does it faster, then person A does more work, but person B has more power. 

g. the newton-meter is a unit of power

h. a 60kg boy runs up a 2.0 meter staircase in 1.5 seconds. his power is approximately 80 watts

3. 074B: Your last graded exam was returned to you Friday - you can make up to four revisions. Show work, and attach the revisions page to your graded exam pages. A copy of the exam is here: https://docs.google.com/document/d/1ZopiFlNWjsTEVp5SbTW-7va_FPM3xh8b90aiDBPvTXg/edit?usp=sharing Due the day of the final

074C: Friday in class I mentioned the significance of December 7th, 1941 in the history of the United States. If you're interested in learning about how politics affects nature, and how the fourth largest lake in the world disappeared in less than a century, here's a great video: https://www.youtube.com/watch?v=AZ5kVH5Ijfg

And, if you'd like to learn about who fired the first shot in Pearl Harbor (it wasn't the Japanese), click below. There's couple REALLY interesting twists to the story, both of which get revealed at the end. 

https://www.youtube.com/watch?v=hcVnByFS7n8

Want some extra credit? Write me a one-two paragraph reflection on each of these videos. And if you want to make it more interesting, come up with a good question or two . Due Monday

GOALS:

1. observe that light can only be seen when it bounces off an object

2. describe which filters transmit certain colors, and which absorb colors

3. see that two filters can combine to affect the color of transmitted light

Warm - Up

1. Natural philosophers have long pondered the underlying reasons for color in nature. One common historical belief was that colored objects in nature produce small particles (perhaps light particles) that subsequently reach our eyes. Different objects produce different colored particles, thus contributing to their different appearance. Is this belief accurate or not? __________________ Justify your answer.

2. What color does a red shirt appear when the room lights are turned off and the room is entirely dark? ____________ What about a blue shirt? ____________ ... a green shirt? ____________
