F=ma

Today we introduced the concept of friction and described the three differing types: sliding, rolling and fluid.  I demonstrated to the kids in the hallway using a hovercraft how a small pocket of air acts as a lubricant and changed the sliding friction into fluid friction.  I also introduced Newton's 2nd Law of Motion, F=ma.  This is the foundation for next week's quiz.  We watched a http://www.brainpop.com/ video on force, and students used the student responders to answer the ensuing quiz.  I ended class by assigning worksheet 6-2, and most students completed that assignment while working with a partner.
No homework was assigned, and the Force Quiz will be next Tuesday, January 26th.  News articles are due on Monday.
