Exploding Soap Bubbles: Hydrogen + Oxygen  
A series of three videos shows that as the ratio of oxygen to hydrogen in soap bubbles increases, the explosions that occur when the bubbles are ignited get louder. (The fact that with an excess of oxygen the explosions would become softer again is not shown.) Each video is repeated with no voice-over so that only the sounds of the explosions are heard. Five still images are provided to show the stoichiometry on the molecular scale. The videos are intended to be shown in order beginning with Hydrogen Alone and ending with hydrogen plus more oxygen.

Matter_and_Measurement : NumOfSigFigs (4 Variations)
How many significant figures will the answer to the following problem contain?

Chemometrics
Equilibrium : CalcKp (2 Variations)
In one experiment chemists studied the formation of phosgene, COCl2, by mixing {y} atm of carbon monoxide and {z} atm of Cl2 in a reaction vessel at 700K. After the system reached equilibrium, the total pressure was {x} atm. Calculate Kp for the reaction.

Hint: Remember that the total pressure is the sum of all the partial pressures.

Note:
      Do Not use scientific notation
      DO NOT use spaces
      DO NOT write in the units.
      Be sure to write your answer with only one decimal place even if this is not the correct number of significant figures.

Chemometrics
Equilibrium : CalcKc (4 Variations)
A container initially has {y} M ammonia at a certain temperature. When the system reaches equilibrium the concentration of ammonia is {x} M. Calculate Kc for the following reaction as written.

Note:
      Answers must be written using scientific notation with "e"
      DO NOT use spaces
      DO NOT write in the units.
      Be sure to use three significant figures.
          eg:       2.44e-5

Helping Students Make Sense of Logarithms and Logarithmic Relationships  Ed DePierro, Fred Garafalo, and Rick Toomey
This paper summarizes difficulties that chemistry students at all levels exhibit when translating, manipulating, and interpreting mathematical expressions containing logarithms, and offers approaches useful in helping students to overcome those difficulties.

Measuring the Density of a Sugar Solution  Karen I. Peterson
This experiment addresses the concept of equipment calibration for reducing systematic error. Students prepare and measure the densities of sucrose solutions with simple glassware that has been calibrated using the density of water. By careful work, students can determine the density to within 0.5%. allowing accuracy to be a major component of the final grade.

Using Candy Samples To Learn about Sampling Techniques and Statistical Data Evaluation  Larissa S. Canaes, Marcel L. Brancalion, Adriana V. Rossi, and Susanne Rath
This easy, interesting exercise demonstrates important aspects of sampling techniques and explores a simple statistical approach to commonly used parameters, the use of histogram, box-plot and whisker plots, and parametric and non-parametric statistical methods.
