Accuracy & Precision Lab Info

How many stations do you have to complete in this lab?

If you're not holding the ruler, you're standing next to your partner incase they need help with their measurement

We are using the ______________________ (unit) side of the ruler and all of our. measurements must be rounded to the nearest 1/10 , which means all Your measurements will contain one _____________ place. (NO WHOLE NUMBERS)

WRITE THE CORRECT ANSWERS IN ORDER, SEPARATED BY A COMMA

How close your shots are to one another is measuring Accuracy

What is the first thing you have to do at each station?

When measuring, where should the first tick mark (zero point) on your ruler be?

Why is Ms. Pipkin making you go slow and follow all of these steps (reading the directions, helping your partner measure, standing in a specific spot, verbally confirming when people are ready, etc.) when it seems like you could do it a lot faster without them?

Below are actions you must do at each station. Put them in order according to when each action should be performed

1. Partner B takes their practice shot, confirms verbally that Partner A is ready and shoots all three shots - verbally confirming with Partner A that they are ready before each shot - while partner A marks their locations on the target
2. Erase all marks on the target and sticky notes (if used)
3. Make sure you're standing in the right place (to the right of the marker on the floor, with your toes lined up to the center of the marker).
4. Partner A holds the ruler to measure (and record in their data table) all 3 shots while partner B double-checks that their ruler and line of sight are lined up correctly and verbally confirms the measurement they see.
5. Switch Spots with your Partner
6. Partner A takes one practice shot and then verbally confirm with Partner B that they are ready for them to start shooting
7. Partner A shoots all three shots - verbally confirming with Partner B that they are ready before each shot - while partner B marks their locations on the target
8. Partner B holds the ruler to measure (and record in their data table) all 3 shots while partner A double-checks that their ruler and line of sight are lined up correctly and verbally confirms the measurement they see.
9. Put the ruler, eraser, instrument, and sticky notes (if used) back on the table.

   **And throw away bad marshmallows if you are at a station that uses them**
10. Read the directions for that station (that are on the wall)
11. Both Partners mark their shot locations on the target in their data table

Select all of the things you will lose 2pts for every time Ms. Pipkin sees you doing this during today's lab.

Today, you need to record your measurements, mark your shot locations, and find your average value for each station.
