4.  What are some techniques I can use to make precise measurements in lab?  Why is it important to make accurate and precise measurements?

5.  Today I will be able to: ◦ Differentiate between accuracy and precision ◦ Apply making accurate and precise measurements to a lab

6.  Write the conclusion for the Accuracy and Precision Lab  Signed syllabus due by Friday, August 29

7.  Warm-Up  Accuracy and Precision Notes  Accuracy and Precision Lab  Accuracy and Precision Lab Discussion  Exit Ticket

9.  Measurement is close to the accepted value

10.  Having more significant figures in a measurement

11. Take 2-3 minutes to read the lab procedure. Put a box around measurements you will record into the data table.

12.  No closed toe shoes or aprons are required

13. Collect data for trial 1 and complete the trial 1 calculations at your desk. Do not complete trial two calculations yet. Record your percent error on the board.

14.  At your table discuss the following questions and be prepared to share out: ◦ What was your percent error? ◦ Were your measurements accurate? ◦ Were your measurements precise? ◦ How did the accuracy and precision of your measurement affect the volume you calculated?

15. Collect data for trial 2 and complete the trial 2 calculations at your desk. Record your percent error on the board.

16.  At your table discuss the following questions and be prepared to share out: ◦ What was your percent error? ◦ Were your measurements accurate? ◦ Were your measurements precise? ◦ How did the accuracy and precision of your measurement affect the volume you calculated?

17. Using the data and the information used in the discussion write your conclusion for the lab. If you do not finish writing the conclusion in class, it will become your homework.

18. What are important components to include in a conclusion? Icebreaker: ◦ If you could turn yourself into something different (car, animal, plant, etc) for one week, what would it be? ◦ Would you rather be 4 inches tall or 100 ft tall?
