Day 83: Annotating Distance-Time Graphs


Students took the d-t graphs from the previous class period and spent time analyzing the graphs using Logger Pro and annotating each segment of the graph. I asked that the annotations be detailed and accurate. Some students have a way to go but most got the basics. Crazy start to the year. One day last week and then a snow day on Friday. Tomorrow (Tues) we expect wind chills of -20F so who knows what the day will be like!

Day 80: Motion Detectors


IS II students did Part I of the Graph Matching lab. They played around with and got used to the motion detectors and Logger Pro. They were asked to use their hand to make graphs of certain shapes – “what does fast away and slow towards look like?” They needed to set the parameters for data collection and then save and annotate their graphs. They needed to understand that slope gave velocity (steeper slope = greater speed, (+) slope = away from detector, (-) slope = towards detector). All in less than 50 minutes, whew! The next time they will “walk the walk” and match their own body movement with distance-time graphs. (Oh, it was hat day — $1 allowed student to wear a hat to raise money for the Four Diamonds Fund and our miniTHON).
