Students, welcome back! We will begin the new year on Chapter 9, which is where we left off. Review the Investigate Activity on page 213. We will complete this lab tomorrow so bring in your empty 2-liter bottles, corks, and twist ties. Remember, essential questions' quiz will be on Thursday, and a test will be given on chapter 9, on Friday. We will use the Prentice Hall textbook in class this week in order to complete some of the interesting activities in this resource. Please study your textbook and the notes that you take in class for homework every night.
Note, we need clean half-gallon milk or juice containers. Please start saving these and bringing them in for labs.
Parents, please monitor this website to help your student keep up with his/her assignments. Also, if your child is sick or misses a day of school for some other reason, then they should be able to keep up with assignments by utilizing this site. Students also need to schedule a day to stay after school to complete make-up work and tests. This is the students' and parents' responsibility! Please note: Students who are absent need to arrange to stay after school on Thursday to make up all missing quizzes and tests. All work is due the first day you return to school from an absence; three days if you have an excused absence.
STUDENTS, TAKING THE ONLINE TESTS IS A GREAT WAY TO STUDY AND TO IMPROVE YOUR GRADE; HOWEVER, IF YOU CAN NOT PASS THE TESTS IN CLASS, I WILL NOT AWARD BONUS POINTS FOR THE ONLINE TESTS! YOU NEED TO STUDY THE ANSWERS ON THE TESTS!!!!!!!!!!!!!!!!! THERE WILL BE NO BONUS POINTS AWARDED FOR ONLINE TESTS UNLESS YOU SUCCESSFULLY PASS THE TESTS IN CLASS. A B or better on the in-class test is required for you to receive bonus points for the online tests. YOU NEED TO STUDY!!!!!!!!! Use link number 4 to access the online tests. Bonus Points make up 25% of your class grade and are considered as class participation points.
Dear Parent,
Your son's or daughter's science class will soon begin exploring the chapter entitled “Energy and Energy Resources.” In this chapter, students will learn about different forms of energy, about energy conversions, and about how we use energy resources in daily life.
By the end of the chapter, students should demonstrate a clear understanding of the chapter’s main ideas and be able to discuss the following topics:
1. the relationship between energy and work (Section 1)
2. kinetic and potential energy (Section 1)
3. a summary of the different forms of energy (Sect. 1)
4. what happens during an energy conversion (Sect. 2)
5. examples of energy conversions among the different forms of energy (Section 2)
6. the role of machines in energy conversions (Sect. 2)
7. how energy conversions make energy useful (Sect. 2)
8. how energy is conserved within a closed system (Section 3)
9. the law of conservation of energy (Section 3)
10. examples of how thermal energy is always a result of energy conversion (Section 3)
11. why perpetual motion is impossible (Section 3)
12. different kinds of energy resources (Section 4)
13. the sun as the ultimate source of energy on Earth (Section 4)
14. the advantages and disadvantages of different types of energy resources (Section 4)
Questions to Ask Along the Way
You can help your child learn about these topics by asking interesting questions as he or she progresses through the chapter. For example, you may wish to ask your child the following questions:
· If a compact car and a bus are travelling at the same speed, which has more kinetic energy? Why?
· Machines can convert energy into a more useful form. What is one way in which your body does the same thing?
· What are some of Earth’s renewable resources?
Thank you for your time and interest. Your participation in your child’s education is a sure way to encourage learning!
Sincerely,
Mrs. Davis

Remember students, 8th grade is your introduction to high school and the challenging, exciting times to come. I'm so excited and I hope that you are too. But, I think you need to study MORE!
And now, "the rest of the story!"
Students, please realiize that studying, taking notes, paying attention, and participating in class are essentials to the learning process. Focus on your work. Study and learn the vocabulary and concepts. Remember, each chapter builds on the last so you MUST LEARN the material. You must study daily! This is excellent information and preparation for high school!
But, I think you need to study MORE! Take the online tests to help you study and remember, you must make a B or better on the final chapter tests in class in order to receive bonus points for the online tests. Absent students need to make sure you complete all the classroom assignments and activities that are listed on this website. Extra credit points will come only from bonus points that you EARN for completing good, quality work that meets the standards, and from passing your tests in class. Please study and do your best work the first time.
The GPS we will be covering are listed below:
S8P2. Students will be familiar with the forms and transformations of the forms of energy.
a. Identify and demonstrate the Law of Conservation of Energy.
This week's lesson steps:
Monday 1/5/09: Teachers' Planning Day
Tuesday 1/6/09: Energy
Essential Questions: What is energy? What type of energy is provided by the foods that we eat? How is energy converted from one form to another? What are the five main forms of energy? Give an example of each. What is the ultimate form of energy on Earth?
Class Activities: Students will complete 15-Minute Manager as they read about energy on pages 107-110, in the Prentice Hall textbook. Students will complete Activity by Doing on page 109, of the Prentice Hall testbook in order to learn the five main forms of energy. Students will read, write up, and/or complete the Investigate activity on page 213.
HW: Read chapter 9, and finish writing up your lab which is due on Thursday. Complete Using Vocabulary on page 240. This assignment is due tomorrow.
Wednesday 1/7/09: Energy and Energy Resources
Essential Questions: What is an energy resource? What are some of Earth’s renewable resources? What is energy of motion? What is energy of position?
