  1. 19 September 2011 • Get Out Homework: None! • Objective: YWBAT… • show what you know about Objectives 1-4 • Do Now: Write a hypothesis about this research question: How does amount of calories eaten each day effect a student’s energy level?

  2. C: Agenda • Do now (5 min) • Correct Exit Ticket Objectives 3-4 (5 min.) • Quiz on Objectives 1-4 (40 min.) • Pretest for Objectives 5-12 Homework: Finish Pretest (on your own!!) Lab report due Thursday

  3. Announcement • Need a good place to work on your lab report? • Come here after school today or tomorrow • I’ll have some school laptops

  4. Objectives 3-4 • Write your updated objective mastery under “exit ticket” for objectives 3-4. • With your partner, discuss your incorrect answers • Correct your answers on the exit ticket! • Put your exit ticket in the “everything else side” under the objective mastery tracker.

  5. Quiz • Complete this quiz silently! • I’ll pick it up when you’re done and give you the pre-test. • Pre-test PAGES 1, 2 and 3 • Due tomorrow (on your own!)

  6. Homework • Finish Pretest (on your own!!): tomorrow • Lab report due Thursday

  7. Manipulating Three-Variable Equations • 16 September 2011 • Get Out Homework: None! • Objective: YWBAT… • write hypotheses, identify variables and design a procedure • manipulate two types of three-variable equation • Do Now: m=nv • Solve this equation for n

  8. Agenda • Do now (5 min) • Exit Ticket Objective 3-4 (10 min.) • Correct Exit Ticket with a partner (5 min.) • Manipulating three-variable equations • Examples (10 min.) • Practice Problems (15 min.) • Exit Ticket (5 min.) Homework: Quiz on Objectives 1-4 Monday Lab report due Thursday

  9. Announcements • Lab report extra help? • Monday, Tuesday • 3:30-4:30 • Room 203

  11. a=bc • Solve for b! • Solve for c!

  12. Solve for b! • Solve for c!

  13. Practice • Solve for y • Solve for z • Solve for y • Solve for z

  14. Practice – in your notebook • Copy and solve the following equations for x: • x = 5(5) • 5x = 25 • 10 = 2x

  15. Exit Ticket • On your own (5 min.)

  17. C: Density • 21 September 2011 • Take Out Homework: Pretest • Objective: You will be able to: • define density and calculate density from measurements • Do now: Rearrange this equation to solve for V:

  18. Agenda • Do now (5) • Density notes and examples (20) • Practice problems (30) • Density Stations (30) • Exit ticket Homework: Lab Report: tomorrow (printed and stapled, ready the first minute of class!) Week 3 Homework #1-5

  19. Reading a graduated cylinder

  20. Density • density: mass per unit volume • How heavy something is for its size • units: g/cm3 or g/mL • 1 cm3 = 1 mL

  21. Examples • Calculate the density of this block of wood! • Calculate the mass of this weight if the density is 8.00 g/cm3. • Calculate the volume of these pennies if the density of pennies is 7.07 g/cm3.

  22. Make this table:

  23. Calculate with your partnerShow your work! • The density of an object with mass of 10.0 g, and volume of 20.0 mL • The density of an object with mass of 10.0 g and volume of 5.00 cm3 • Calculate the mass of a sample of matter with a volume of 10.0 cm3 and density of 2.0 g/cm3 • Calculate the volume of a rock with mass 100.0 g and density 5.00 g/mL.

  24. A: 20 September 2011 • Grab a calculator • Take Out Homework: Pre-test • Objective: You will be able to: • make accurate measurements and use them to calculate density, mass and volume • Do now: Calculate the mass of a 20.0 cm3 block of wood with density 0.40 g/cm3. Show your work!

  25. Agenda • Do now • Review: Estimating length and volume • Density stations! • Exit Ticket Homework: Week 3 Homework #1-5 Lab report due tomorrow!

  26. Stations • With your lab group, visit each station (9 min. each) • Work quickly to determine what measurements you need to make, and record them (with units!) in your notebook. • Then, calculate the quantity specified on the poster. Include units!

  27. In Your Notebook: • Station 1:

  28. Expectations • Stay with your group and move on only when the timer gongs. • Begin working immediately. • Use a reasonable, quiet professional voice. • Return all items to the station in an organized way. • Show all your work neatly!

  29. Discuss • What makes something float or sink in water? • Why?

  30. Exit ticket • Use the back for III.

  31. Homework • Be sure each quantity has units!! • Week 3 Homework #1-5 • Lab Report: tomorrow • Must be printed and stapled and on your desk in the first minute of class tomorrow!
