Stoichiometry - Relationships

The Stoichiometry - Relationships Concept Builder challenges learners to make connections between the amounts of reactants and products for a chemical reaction. There are three levels of difficulty with each level adding a more sophisticated set of calculations. To complete a level, students must analyze a reaction and complete a five-row table that includes missing amounts of reactants and products. The Apprentice Difficulty Level includes all amounts in the unit mole. The Master Difficulty Level includes one of the quantities in units of grams and the rest as moles. And the Wizard Difficulty Level requires two different mole-to-gram conversions.

A built-in number pad makes numerical entry very easy on mobile devices.Feedback is immediate and learner progress is tracked using a health bar. Learners can repeat a difficulty level in an effort to improve their health percentage. Help is provided for each difficulty level. Built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
