Begin Pendulum Lab; uncertainty intro

-Collect permission slips

-Return Inquiry Cube Activity Lab & glue into notebooks

-Notes and warmup from slides: 

Warm-up Question: (F 1.1)

Ariel and Brock each measure their chromebook 3 times and get the follow measurements:

Set A:28, 29, 30
Set B: 28.9, 29.0, 29.1

What is the same about these data sets?

What is different about these data sets?

Which sets seems better? Why?

Summarize these two data sets.  How do we communicate one seems better than the other?

Set A: 8, 10, 12

Set B: 4, 10, 16

Average   Uncertainty

   10 +/- 2

   10 +/- 6

Uncertainty in Average = Range/2

Range = biggest number – smallest number

-Begin Lab #1: Pendulum Lab

-Follow Inquiry & Patterns Slides

Practice: Time a Rolling Ball

In hallway do several trials rolling a ball from point A to point B.
