What do Chemists See When they Look at Chemicals?
In this naming chemicals learning exercise, students indicate the prefixes for naming compounds. They fill in a chart with the chemical names and formulas for alkanes. They draw the structural and molecular formula for propane and they...
Curated OER
Empirical Formulas
Young scholars investigate empirical formulas for molecules. In this empirical formulas lesson plan, students use paper ions to form formulas and they show these are empirical formulas. They use ions of carbon and hydrogen showing...
Curated OER
Models of Hydrocarbons
Young scholars construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...
Curated OER
Naming Molecular Compounds
In this naming molecular compounds worksheet, students are given 8 formulas of molecular compounds and they write the names for each. Students are then given 8 names of molecular compounds and they write the formula for each.
Curated OER
Worksheet 2-2 Stoichiometric Tools
In this stoichiometry worksheet, learners solve a variety of problems including finding empirical and molecular formulas, determining molarities of solutions, determining molecular weights of compounds and calculating the percent mass of...
Curated OER
Molecular Models
In this molecular formula worksheet students fill in a table describing elements and chemical formulas. They identify, elements by type and how they bond. The student analyze molecular formulas to identify the number of atoms and if the...
Curated OER
Molecular Modeling Activity
Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...
