1. January 16, 2018 Warm-Up: Speed worksheet
Take out lab sheet from Friday – work on finishing graph after warm up
Take out GIZMO if not turned in – will be collected shortly
HOMEWORK: USA Test Prep Speed & Acceleration Practice due Friday. Quiz on speed on Thursday – see blog for info.

2. Today’s Agenda Warm up worksheet Finish speed lab graphs from Friday
Calculate AVERAGE SPEED for all 4 graphs – put that on the graph along with a key (average speed = total distance/total time)
Complete displacement activity – turn in when complete
Read The Martian if you finish all work before class is over

3. Speed Lab I need volunteers:
10 people who don’t mind using their phone as a stop watch (and know how to do this)
10 people to record time data
4 people to walk

4. Procedure Each timer will stand at 1 meter intervals
Everyone starts their stopwatch when I say go
The walker starts walking
Walker 1: 10 meters, constant pace
Walker 2: 10 meters, increasing speed
Walker 3: 5 meters, constant pace; 5 sec rest; 5 meters, constant speed
Walker 4: 5 meters, constant pace; 5 sec rest; return to start
Stop your timer as the walker passes
Recorders will record the time
