1. Taking Notes • Why you should bother, and how to do it well.

2. Why bother with notes? • Taking notes helps you: • understand more deeply • pay attention • figure out what questions to ask • do your homework more easily • study for tests

3. Effective note-taking • Some ways of taking notes help a lot more than others. • Make the notes “yours” • Use abbreviations • Add/flag questions • Don’t copy what’s on the board word for word.

4. Let’s Practice • Give your best effort to take notes on the next slide. • Don’t worry about getting it “right” • You may be asked to show what you wrote with the class.

5. Kinetic Energy • Kinetic energy is the energy a moving object has because of its motion. • The kinetic energy (K.E.) of a moving object depends on the object’s mass (m) and its velocity (v). mass in kilograms (kg) velocity in meters per sec (m/sec) • The SI unit of energy is the joule, abbreviated J. 5

6. Share out - shoulder partner • Switch notes with your shoulder partner. • Read your partner’s notes. • Tell you partner one positive thing you noticed about his/her notes.

7. Some general tips Example • Use HEADINGS • with lists of stuff underneath • not full sentences • think “caveman texting” • highlight or underlinekey ideas • KINETIC ENERGY • obj. has bcse of motion • KE depends on mass & velocity • mass = kg velo = km/s • unit of NRG= Joule http://youtu.be/-lgC96tCRbY

8. More Practice, with Math • Give your best effort to take notes on the next few slides. • Don’t worry about getting it “right” - this is about finding things that work for you • You may be asked to show what you wrote with the class.

9. Expressions vs. Equations • “Simplify” “Solve”

10. Expression • Just a series of mathematical terms (variables and constants) • Not necessarily equal to anything • May be a constant expression: • 3+5-2 • May be a variable expression: • 3x+5-2 This expression always has the same value. It’s value is CONSTANT This expression varies depending on what X is. It’s value is VARIABLE

11. Simplify Expressions • You can simplify expressions by combining LIKE TERMS • You can’t solve variable expressions. Simplify: 3x-5+2x-3(x+1) X could be any number. The value of the expression depends on what you plug in for X 2x-8

12. Equations • One side is EQUAL to the other • Examples: • 3+2=5 • 2x+6 = 8

13. Solving Equations • You can SOLVE an equation by finding out what makes one side equal to the other. • Solve 2x+6=8 • To make this true, x must be equal to 1

14. Add in questions • Look back through the notes you took and write in questions you have. • It might look like this: example? Expressions - series of math terms - not necess. = to anything series = “bunch”?

15. Share out - SU-HU-PU • Stand Up • Hand Up & Mingle • Pair Up • Repeat with your new partner - trade & praise
