Percent Composition, Measurements  High School
Lab: Mineral Investigation
In this lab, students will put their problem solving skills to work as a team to determine how many specific samples of ore can be made from a lode equivalent to the size of their classroom. This lab is perfect for the start of the school year to engage students in reallife applications of chemistry, as well as essential mathematic and measurement skills.

Mole Concept, Dimensional Analysis, Measurements  High School
Lab: Calculating Moles
In this lab, students will have the opportunity to practice conducting the chemist’s way of counting atoms and molecules by using the mole. They will determine the mass of various common elements and compounds and convert this data into values of moles, atoms and molecules. This will allow students to realize the connection between commonly used laboratory chemicals and the quantitative data and calculations that are such a fundamental part of chemistry.

Mole Concept, Significant Figures  High School
Activity: Can You Color A Mole?
In this activity, students determine how many moles of paraffin are used when they color a piece of paper as well as how many molecules and moles of wax are in one crayon.

Mole Concept, Dimensional Analysis  High School
Activity: Bring Me A Mole
In this lab, students take an abstract concept, the mole, and turn it into a real measurable concept.

Density, Review, Dimensional Analysis, Measurements  High School
Lab: Bowling Ball—Will it Sink or Float in Water?
In this lab, students will find the density of a bowling ball to determine whether it will sink or float in water.

Dimensional Analysis, Significant Figures  High School
Lab: Nanoscale and SelfAssembly
In this lab, students determine both the diameter of one single BB and the length of an oleic acid molecule.

Measurements, SI Units  High School
Activity: Mysteriously Melodramatic & Maniacal Metric Measurements
In this activity, students predict the measurements of objects using metric units. They then take the actual measurements and compare them to their predictions.

Mole Concept, Dimensional Analysis  High School
Lab: Moles of Food
In this lab, students will analyze the nutrition label of a variety of foods to find the amount of specific elements in each serving. Students are asked to evaluate and compare the data in a series of questions, in order to convert the values to moles. This lab gives students the opportunity to see the connection between the chemistry mole concept and everyday foods.

Mole Concept  High School
Lesson Plan: Molar Marks
In this lesson, students will better understand the mole concept by using chalk to write their name on a sidewalk and finding out the composition of chalk through research.

Separating Mixtures, Percent Composition  Middle School
Lab: Metallic Breakfast
In this lab, students will separate iron filings from ironfortified breakfast cereals. Students will use the recorded data to conduct percent composition calculations.

Introduction, Measurements  High School
Lab: Math and Measurement
In this lab, students will practice introductory math skills that will be used in chemistry all year. This includes metric conversion, significant figures, scientific notation, dimensional analysis, density, percent error, accuracy and precision, as well as using lab equipment.

Percent Composition, Introduction, Percent Composition, Scientific Method  Middle School
Lab: Mass Percent
In this lesson, students will develop a theory of how to calculate percent composition.

Conservation of Mass, Conservation of Mass, Measurements  Middle School, High School
Lab: Mass & Change
In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.
