Multimeida Science - Chemistry Series

	Balancing Equations This tutorial includes a brief history of the conservation of mass, step by step instructions and strategies on balancing equations, and a set of 40 problems in four sets of ten with increasing difficulty. A score is kept for each of the four sets of problems.

	Naming Formulas Students can practice naming chemical formulas in two game formats. The first format is a matching game where students must match the name with the correct formula. The second format is a shooting game where students are given the name and must shoot the correct formula. The final shooting game requires the students to shoot only the ionic and not the molecular compounds. Covers basic ionic, molecular, and simple acids.

	Equilibrium Simulator The equilibrium simulator lets you choose the coefficients in the chemical equation A + B = C + D Then you can add molecules of A, B, C, and D to the reaction chamber and set the desired equilibrium constant. When the simulation is started, the reaction will proceed indicating how the numbers of each reactant and product are changing and moving towards the equilibrium constant.

	Gas Laws Lab The gas laws lab illustrates the three relationships between temperature, volume, and pressure: V vs T, P Vs V, and P Vs T. Data can be taken and graphed to show the basic relationships. Students see and hear clearly the correlation between pressure and the collisions of the gas molecules against the sides of the container.

	Ideal Gas Law Simulator The Ideal Gas Law Simulator is based on the ideal gas law PV = nRT. When the simulation is started, these four variabls are set to some reasonable initial values. Then after choosing any two of the four variables, one variable can be varied while the other changes. When one of the variables is n, only n can be changed. A box with a movable top contains bouncing molecules which illustrates the changes to the four variables. As the volume changes, the top moves up and down. As the temperature changes, molecules in the box move faster and slower. As the number of moles,n, changes, the number of molecules bouncing in the box increases or decreases.

	Acids & Bases This CBI module covers much of the curriculum on acids and bases typically taught in the accelerated chemistry course. There are a number of simulations including one on performing titrations and one on the basic tests for pH using test papers. The software includes over 200 screens and each of the sections includes a test. The last section is a project where students work for a chemical testing company.

	Chemware This CBI module is a "pictorial tutorial" on the chemisty equipment used in a typical high school chemistry course. The software includes a set of quizzes, information on safety and safety equipment, and diagrams of typical laboratory setups. The software includes excellent pictures of chemistry equipment, which were included courtesy of VRW Scientific Products. Created using Authorware.

	Name That Element II In this game, the symbols for the elements will drop from the top of the screen. Students must click on the correct name from a list at the bottom of the screen before the dropping symbol reaches the bottom.

	Light As the hand is dragged along the frequency scale, the change in frequency, wavelength, and pitch is illustrated.

	Name That Element Game In Name That Element, students play three games designed to help them learn the 51 most common element names and symbols. In the falling elements game, they must shoot the correct symbol that matches the given name. In the matching elements game, they must match the symbols to the correct name. And in the identify the elements game, they must match up a list of element names with a list of interesting and unusual information about those elements.

	Dropping Ions Game In this game, students maneuver positive and negative ions into rows as they drop from the top of the playing field. The goal is to get each row of ions to add up to zero. Before the game starts, students can choose to have the total charge of each row shown and / or have the charge of each ion shown. If they do either, however, they cannot add their names to the list of high scores. They also can destroy up to four of the ion blocks to help achieve the goal.
