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 (Section 1)

4                    what happens during an energy conversion (Section 2)

5                    examples of energy conversions among the different forms of energy (Section 2)

6                    how energy conversions make energy useful (Section 2)

7                    how energy is conserved within a closed system (Section 3)

8                    the law of conservation of energy (Section 3)

9                    examples of how thermal energy is always a result of energy conversion (Section 3)

10                different kinds of energy resources (Section 4)

11                the sun as the ultimate source of energy on Earth (Section 4)

12                the advantages and disadvantages of different types of energy resources (Section 4)

 

Thank you for your time and interest. Your participation in your child’s education is a sure way to encourage learning!

Sincerely,

 

Amy Shannon
