  2. Precision and Accuracy UnitMonday • Objective: SWBAT explain the difference between precision and accuracy. • BR: What do you think of when you hear the word accuracy? Precision? • Lesson: • Notes (handout) about Metrics (base units, etc) • Notes- Precision and Accuracy (Powerpoint) • Reading Lab Equipment • HW: finish “Reading Lab Equipt”

  3. Precision and Accuracy Unit Tuesday, September 13, 2011 • Objective: SWBAT explain why we use significant figures and determine how many significant figures are in a number. • BR: What is the difference in the meaning of these two numbers: 10210 mL and 10210. mL ? • Lesson: • Notes- Significant Figures (Handout) • Practice Significant Figures • Notes- Addition/Subtraction/Mult/Dividing with Sig Figs • HW- front back sheet with sig figs on one side and calculations on the other • HW: finish practice worksheet

  4. Precision and Accuracy Unit Wednesday, September 14, 2011 • Objective: SWBAT place numbers in scientific notation with the correct significant digits. • BR: Please write #1 out in complete sentences. • 1.

  5. Precision and Accuracy UnitThursday, September 15, 2011 • Objective: SWBAT add, subtract, multipy and divide numbers in scientific notation. • BR: • 1. Add the following numbers and express your answer in the correct # of Sig Figs: 2.345 + 5.123+ 4.1 + 2.11 = 13.678 cm • 2. Multiply the following numbers and express your answer in the correct # of Sig Figs: 2.34 cm x 1. cm = • Lesson: • Clicker! • Groupwork • HW: Finish Wksht

  6. Precision and Accuracy UnitFriday, September 16, 2011 • Objective: SWBAT apply the concepts of precision and significant digits to reading lab equipment. • BR: How do significant digits relate to precision of an instrument? • Lesson: • Clicker • Extend/Reteach • Calculations with Scientific Notation Review • HW: REVIEW!!!

  7. Precision and Accuracy UnitMonday, September 19, 2011 • Objective: SWBAT perform calculations with numbers in scientific notation. • BR: Write the following numbers in scientific notation: • 0.000520 • 5302000 • 0.0002 • Lesson: • Go over BR • Complete Significant Figures! (with drawing out graduated cylinders in 4-8) • Notes on Sci Not Mult/Division calculations • Practice: Unit 1: Sci Notation Wksht- (do a-h and go over, then do a-j below) • Go over a-j • HW: Finish Sci Not Calculations (k-n)

  8. Precision and Accuracy UnitTuesday, September 20, 2011 • Objective: SWBAT use lab procedures to measure volume, mass and length using the metric system. • BR: What units would you use to report the following: • Mass • Length • Volume (there are 2!!!) • Lesson: • Go over BR • Go Over TOOLS LAB • VOLUME LAB • HW: Review!

  9. NOTE for 2012 • Didn’t teach addition subtraction to all classes • (some missed a day for assembly)

  10.
