  Lab: Extracting Copper From Ore

  In this lab, students extract copper from copper carbonate using two different methods, and then determine which industrial method is most effective.

• 

  Mole Concept | High School

  Activity: Popcorn Counting Unit

  In this activity, students develop a new method of counting objects, called the PCU, and compare this method to the concept of the mole.

• 

  Percent Composition, Percent Composition, Mole Concept, Dimensional Analysis | High School

  Lab: Percent Composition of Bubble Gum

  In this lab, students will be introduced to the concept of percent composition. Students will determine the amount of sweetener in various brands of gum by determining the mass difference of the gum before and after it is chewed.

• 

  Mole Concept, Measurements, Dimensional Analysis, Molar Mass | 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, Dimensional Analysis, Density | 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.
