Dear Families,
The next chapter we will be studying is "Energy" found in Chapter 14 in our textbook. Students will be defining the 15 vocabulary words from the textbook on pages: 639, 649, and 661. They will also be creating vocabulary flashcards for the chapter. Please note that there are also pre-made flashcards for the entire textbook glossary in the back of the Reading Support and Homework online book (pages: RS161 - RS263). There will be a vocabulary practice quiz, graded vocabulary quiz, and a chapter test. All Power Points used in class are now online in PINK under the lessons below!
Here are the vocabulary words, learning objectives, Power Points,
and essential questions for Chapter 14. . .

Frequently Asked Questions About Chapter 14:
Page 646 shows a lightning flash, which transfers energy between clouds or from clouds to earth. How far away is lightning from you?
| If Thunder is heard | The Lightning is... |
| 5 seconds after a Flash | 1 mile away |
| 10 seconds after a Flash | 2 miles away |
| 15 seconds after a Flash | 3 miles away |
| 20 seconds after a Flash | 4 miles away |
| 25 seconds after a Flash | 5 miles away |

Can potential and kinetic energy happen at the same time?
Yes, they are inversely proportional. As one increases, the other decreases. Think of a skier. At the top of a slope he has potentional energy. As he is is traveling down the slope, his potential energy is decreasing and his kinetic energy is increasing. As he approaches the bottom of the slope, his potential energy is now increasing and his kinetic energy is decreasing.
Does hydroelectric mean that water is actually turned into electricity?
No. It means that water is used to turn the turbines, which generate electricty.
