Different Places

Every course is working on something different right now, so things are pretty busy. Physics - the lab today on momentum and impulse, helped demonstrate the concpets that A block discussed on Wednesday and that E block will discuss tomorrow. Due to the less-than-frictionless lab situation, don't expect your impulse and momentum change values to be dead-on exact. They should be reasonably close, though, and we'll discuss the ranges of people's data tomorrow.

Honors Physics - tidied up the remnants of the momentum chapter. Exam on Wednesday. Bring questions for tomorrow's review and today's chapter review problems to discuss.

Physical Science - An overview and a couple of demonstrations of buoyancy. Tomorrow's lab will highlight those ideas and add in the concepts of calculating buoyant forces (rather than measuring them) and predicting floating and sinking for an object placed in a fluid. Even though water will act as our fluid in tomorrow's lab, the concept of buoyancy, buoyant forces and Archimedes Principle apply to all liquids and gases.

General Note: Some groups are getting a little careless in lab, in terms of equipment. First off, keep an eye on all the pieces for your sensors. Already, a couple of force sensors have lost their thumbscrews. Secondly, only put the sensors, LabPros and cables in the containers. I should not find heavy masses, string, scissors, etc. in there. Lastly - CLEAN UP WHEN YOU'RE FINISHED!!! Some groups do a great job with clean up and others do a terrible job. I am goign to have to start holding groups after class to clean up their stations if you can't take the initiative on your own. Repack materials, throw away trash (in the trash can, not the sink or lab drawers), return materials you borrowed from other groups to them, etc. Saves time for me and groups using the equipment after you.
