Exploring Friction

This activity occurs after students have had a chance to "Explore Friction at Home" and before students do a simulation of the traditional Ff vs. Fn lab. Slides 1-7 were teacher-led and completed one-by-one with students. Observations about the possible factors affecting friction were added to students' notes. Slides 8-15 were completed as homework. There are 2 videos that students might want to replay/refer to as they work through the slides, so this makes a good asynch portion of the activity. Videos on Slides 1 and 5 are by Eugenia Etikina. Video clips and stills on slide 8-13 are by Aaron Debbink - https://www.youtube.com/watch?v=u6UNpVP8pZI Yellow force diagram graphics are from Tom Henderson's "The Physics Classroom" website.
