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.

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

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

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
