Curated OER
Gas Law Summary
In this chemistry worksheet, high schoolers memorize a pneumonic phrase in order to remember the Gas Law and then apply this to other content as well.
Curated OER
CheMATHstry That Sticks Right to You
Students find the percent composition of sugar in the gum. In this chemistry lesson, students calculate percent error from the experiment. They use dimensional analysis to convert between units.
Curated OER
The Mole
Students explore the concent of using the mole to solve problems related to counts small particles of matter. Students work individually and in groups to complete conversions of substances from moles to matter.
Curated OER
Ammonium Nitrate - Efficient Fertilizers
Students study the chemistry of ammonium nitrate and consider the advantages and disadvantages of this compound. They compare different fertilizers and calculate the molar mass and percent nitrogen in the different fertilizers.
Curated OER
Stoichiometry
In this stoichiometry worksheet, students identify types of reactions, show the products, and balance the equations. Students determine the limiting reagent, theoretical yield, and percent yield for given reactions. This worksheet has 5...
