Sink or Float?

Thanks for class today, friends-- good concentration and good cooperation.  Take a few minutes to clean up and re-write your lab report, according to the outline given.  It doesn't need to be many words, but it is crucial that you be able to put into words the discoveries that you made.  That way you can keep them and build upon them.  What is the Big Idea that you come away with?

Then take a look at your personal density experiment, which you will present on next Thursday to the whole class.  Get your supplies and try it out with your little brother or your dad. Be prepared to demonstrate and explain in about 3-4 minutes.  Contact me if you have questions or needs. THINKING ABOUT THIS: Could about 6-8 of you students prepare to do your experiment on Monday? Comment below if you can--I would appreciate you volunteering.  Class is too short for everyone to do theirs on Thursday. THANKS!

Lastly, a BrainPop.  http://www.brainpop.com/science/motionsforcesandtime/buoyancy/preview.weml
