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

Chemometrics
Equilibrium : CalcRxnQuotient (13 Variations)
In an experiment, 4.44 mol of SO2, 7.93 mol of O2 and 4.03 mol of SO3 are placed in a 2.0L reaction vessel at a certain temperature. Calculate the reaction quotient, Q, for the reaction as written:

What is the calculated reaction quotient, Q? {2:NUMERICAL:=2.1e-1:1e-2#Correct! ~%50%2.1e-1:5e-2#Close but not quite right}

If Kc for this reaction at the temperature of the experiment is 3.7 x 103, will the reaction move toward the left or toward the right? {1:MULTICHOICE:left#Sorry, that's wrong.~=right#Correct!}

Equilibrium : CalcMolesAtEquil (15 Variations)
The following reaction has an equilibrium constant of 0.083 at 900oC.

COCl2(g) CO(g) + Cl2(g)

If you have 1.00 mole of COCl2(g) in a 1.00L container initially, how many moles of COCl2 will be present when the system reaches equilibrium?

An Easy and Effective Classroom Demonstration of Population Distributions  Marjorie A. Jones
Using a simple experimental design and easily obtained materials, a classroom experiment was conducted to demonstrate normal-distribution behavior for a population. We used popcorn and a hot-air popper. Popped kernels were collected with time and data were plotted as popped kernels per time interval versus time. The data clearly showed a normal (Gaussian) distribution.

A mole of M&M's   Merlo, Carmela; Turner, Kathleen E.
Engaging students by asking the question: How thick would the layer of M&M candies be if we covered the continental United States with a mole of these candies? Compare this to a mole of water.
Merlo, Carmela; Turner, Kathleen E. J. Chem. Educ. 1993, 70, 453.

Distance and Time at the Finish Line?  
In this activity, students measure and chart the time, distance and speed of various movements.
Chemometrics
Do the Swing Thing?  
In this activity, students investigate pendulums, and how changing the mass and length affect the rate of swinging.
Chemometrics
It?s Gonna Be Big?  
In this activity, students chart how a balloon changes in size as they blow it up. They use the graphed data to make predictions about the balloon behavior.
