Density of Salt Water (Movie)
Steve Spangler demonstrates the affect of salt on the density of
water. A fun video to watch.
Here is a little game with significant figures. There are 12
different numbers for students to determine the number of
significant figures. They are to keep the number of wrong tries
to a minimum!

Chemistry: Scientific Measurements
In order to produce the best quantitative results the
student/experimenter will learn how to identify the error in a
measure and apply this while measuring mass using the electronic
balance and volume using various volumetric instruments.
Dimensional Analysis: This
video tutors students on dimensional analysis. Includes
discussion about Avogadro's number and the mole.
