• Concentration, Solute & Solvent, Molarity, Stoichiometry, Mole Concept, Dimensional Analysis, Tyndall Effect | High School

### Access is an AACT member benefit. Activity: Solubility & Solutions

In this inquiry activity, students investigate types of solutions, identifying the solute and solvent, and classifying each solution. They them solve stoichiometry problems involving solutions of different concentrations.

• Balancing Equations, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis, Measurements | High School

### Access is an AACT member benefit. Activity: S'more Stoichiometry

In this activity, students determine the number of graham crackers and chocolate pieces required to complete a “reaction” with a given quantity of marshmallows (the limiting reactant). They then use the same thought process with a problem involving a real chemical reaction.

• Concentration, Molarity, Percent Yield, Stoichiometry, Classification of Reactions, Limiting Reactant, Mole Concept, Chemical Change, Dimensional Analysis | High School

### Access is an AACT member benefit. Demonstration: First Day Review

In this demonstration, students see evidence of a chemical reaction.

• Molecular Formula, Law of Definite Proportions, Stoichiometry, Classification of Reactions, Mole Concept, Dimensional Analysis | High School

### Access is an AACT member benefit. Lab: Finding the Formula of Magnesium Oxide

In this lab, students will recognize that oxygen has mass and that heating can involve and increase in mass as an element reacts to become an oxide

• Concentration, Precipitate, Net Ionic Equation, Balancing Equations, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis | High School

### Access is an AACT member benefit. Lab: Finding CO2 Mass in your Breath

In this lab, students will measure how much carbon dioxide they exhale by reacting their exhaled breath with limewater (calcium hydroxide solution). Students will practice writing balanced equations and completing mass-to-mass stoichiometric calculations.

• Reduction, Percent Yield, Activity Series, Stoichiometry, Redox Reaction, Classification of Reactions, Mole Concept, Chemical Change, Dimensional Analysis, Measurements, Oxidation, Error Analysis | High School

### Access is an AACT member benefit. 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

### Access is an AACT member benefit. 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

### Access is an AACT member benefit. 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, Dimensional Analysis, Measurements, Molar Mass | High School

### Access is an AACT member benefit. 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.

• Molecular Formula, Mole Concept, Dimensional Analysis, Measurements, Scientific Notation, Molar Mass, Significant Figures | High School

### Access is an AACT member benefit. 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, Measurements | High School

### Access is an AACT member benefit. Activity: Bring Me A Mole

In this lab, students take an abstract concept, the mole, and turn it into a real measurable concept.

• Gas Laws, Balancing Equations, Stoichiometry, Mole Concept, Chemical Change, Dimensional Analysis, Volume | High School

### Access is an AACT member benefit. Project: Air Bag Stoichiometry

In this lab, students make real-world connections of stoichiometry with the design of car air bags.

• Concentration, Acid Base Reactions, Molarity, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis, Measurements, Indicators, pH | High School

### Access is an AACT member benefit. Lab: Acid/Base Stoichiometry

In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.

• Density, Mole Concept, Dimensional Analysis | High School

### Access is an AACT member benefit. 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.

• Mixtures, Concentration, Solute & Solvent, Molarity, Mole Concept, Dimensional Analysis, Measurements | High School
