This is an assignment that has students using the internet to
research the different types of chemical reactions. They then
design a pamphlet advertising what they learned using computer
Types of Equations: This
document is intended to help the chemistry student learn the
basics of writing and balancing equations, how to predict the
products of four general types of inorganic reactions and how to
write and balance equations for the combustion of hydrocarbons.
There are also practice exercises for each section.
Conservation of Matter: The
experiment will explore whether matter is created or destroyed
during a chemical reaction. Instructions give household
Stoichiometry of Cooking: In
this activity, the importance of stoichiometry is emphasized by
teaching the effect of changes in ingredients on a final
product. Baking is fun, and when kids are having fun, they’re
more open to learning new ideas. The analogy to stoichiometry
deals with relative amounts of ingredients, with measurement of
weights and volumes, and with the analysis of the chemistry
which is involved in baking. You will need access to ovens.
Stoichiometry Lab: This
experiment utilizes the PASCO GLX temperature sensor to
determine the optimum ratio of sodium hypochlorite and sodium
thiosulfate. I have done this lab in my classroom and it works
WRITING IONIC EQUATIONS FOR REDOX REACTIONS: This
page explains how to work out electron-half-reactions for
oxidation and reduction processes, and then how to combine them
to give the overall ionic equation for a redox reaction.
Reduction/Oxidation Chemistry: In
this exploration you will use PASPORT pH and ORP electrodes to
investigate increasing and decreasing the pH of a solution of
bleach and how this affects the effectiveness of the bleach as a
Fun Things One Can Do With Bleach: 2
of the 3 experiments demonstrate redox reactions using bleach
and iodine. Explanations accompany the demonstrations.
LeChatelier's Principle: This
flash animation illustrates the effects of temperature,
pressure, and concentration on equilibrium.
Chemical Equilibria: Le Chatelier's PrincipleThis
applet allows students to change amounts, volumes, and
temperatures to observe the changes in equilibrium. It also has
students calculate equilibrium constants at various conditions.
Heat of Combustion of Candle Wax (Experimental Design): In
this lab heat energy from a burning candle is directed to a Coke
can filled with water. The elevation in the temperature of the
water as the candle burns indicates heat is being transferred.
Students should readily observe the principle of heat exchange.
Students must attempt to design the procedure and equipment such
that heat is neither gained nor lost to the environment. The
student then must calculate the heat of combustion of candle wax
(i.e., the amount of heat energy released per gram of wax
Heat of Solution: In
this experiment, students will use a Temperature Sensor to
investigate the enthalpies of several reactions. Students will
analyze their data in order to determine whether their data
supports Hess's Law.
Resources/Waste: Home Chemicals: This
exercise involves conducting an inventory of the types of
chemicals in the home.
LOUISIANA'S COASTAL NONPOINT POLLUTION CONTROL PROGRAM: This
document reviews the regulations governing Louisiana coastal
pollution control program.
