In this air instructional activity, high schoolers determine the major gases found in the earth's atmosphere and review STP and Avogadro's Law. This instructional activity has 1 true or false, 2 fill in the blank, and 7 short answer...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a instructional activity in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what...

In this conversion worksheet, students make the following conversions, showing each step. Students use the periodic table and express all molar masses to 1 decimal place.

High schoolers explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

In this worksheet, students calculate the density, molar mass, and volume of given word problems. Students also calculate the partial pressure of the gases given in the particular problem.

In this compounds worksheet, pupils determine the number of molecules in molar mass for given amounts of different compounds. This worksheet has 5 problems to solve.

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.

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive activity. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...
