September 4th, 2014 AGENDA: 1 – Bell Ringer & Agenda 2 – Ring of Truth Video and Questions 3 – Notes: Law of Conservation of Mass 4 – Uncertainty in Measurement Lab 5 – Exit Slip Today’s Objective: SWBAT explain the uncertainty in measurement and demonstrate how to read graduated cylinders and rulers. Due Today: • Mass and Change Lab Summary in Notebook • Uncertainty in Measurement Lab Homework: • Measurement Practice – due Friday 9/8 • Quiz: Conservation of Mass 9/8

  8. Ring of Truth Video • Open Showbie – EQ2UP • Open Ring of Truth Video Questions

  9. CN: Conservation of Mass • Get out your chemistry notebook • Set-up a set of CN on page 7 of your notebook • Objective: SWBAT explain the law of conservation of mass and physical vs. chemical changes.

  10. Uncertainty in Measurement • Measure length and width of whiteboard in glugs, calculate area. • Use a lined piece of paper to divide your glug into 10 even parts (1/10 of a glug). • Measure the length and width of your white board again, calculate area. • Measure the length and width of your whiteboard using a centimeter ruler. • Determine volume of water of 12 graduated cylinders (read from the bottom of the water)

  11. Uncertainty in Measurement • Measure length and width of whiteboard in glugs, calculate area. • Use a lined piece of paper to divide your glug into 10 even parts (1/10 of a glug). • Measure the length and width of your white board again, calculate area. • Measure the length and width of your whiteboard using a centimeter ruler. • Determine volume of water of 12 graduated cylinders (read from the bottom of the water) Estimate 1 significant figure past what your measurement tool tells you!

  19. Nature of Science Puzzle • Aspects of Science: Tentativeness, Creativity, Observation, Inference, Subjectivity, Empirically Based, Socially Culturally Embedded. • Scientific investigations begins with a QUESTION. • Explanations are developed from a combination of collected data and what is already known.

  20. Can Demo & White-boarding • Each pair needs a WB, marker and washcloth. • DRAWING PICTURES, answer the following questions: 1. What is happening when the gas is turned on? 2. What is happening when there is a flame? 3. What is happening when the flame goes out? 4. What is happening at the end of the demo?

  21. Safety: What-Not-To-Do Lab • Work with your table partner. • Look at the pictures, and use your knowledge of lab safety to determine what is wrong with the picture. • Record the problem and how it should be fixed to make that situation safe for the lab.

  22. EXIT SLIP • DILQ • D: What did you do in class today? • I: What did you find interesting? • L: What did you learn in class? • Q: Questions? (Must write at least 1) • What is your Homework?
