Warm-Up Accuracy and Precision Notes Accuracy and Precision Lab Accuracy and Precision Lab Discussion Exit Ticket

Measurement is close to the accepted value

Having more significant figures in a measurement

Take 2-3 minutes to read the lab procedure. Put a box around

measurements you will record into the data table.

No closed toe shoes or aprons are required

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.

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?

Collect data for trial 2 and complete the trial 2 calculations at your desk. Record

your percent error on the board.

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?

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.

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?
