Concentration, Solute & Solvent, Molarity | High School

Simulation: Preparing Solutions

In this simulation, students will complete a calculation in order to determine the value of an unknown variable related to a described solution and then they will observe an animation of the solution being prepared. The calculation will require the student to determine either the molarity of solution, volume of solution, or mass of solute needed. Additionally the associated particle diagram for the solution will be displayed to help students better visualize the solution at the particulate level. Finally, students will gain familiarity with the proper lab techniques for preparing a solution as they are lead through a step-by-step animated process demonstrating this procedure. The simulation is designed as a five question quiz for students to use multiple times.
Concentration, Identifying an Unknown, Molarity, Balancing Equations, Classification of Reactions, Chemical Change | High School

Lab: An Environmental Impact Study

In this lab, students will test a water sample which comes from a local zoo, where, it is reported that many bird eggs are not hatching. Students will test the water for the presence of multiple ions. Once the type of ion in the water is determined, students will write balanced equations to illustrate their findings. Students will also conduct a serial dilution to determine the concentration, or molarity, of the ion in the water sample. This molarity will be compared to known values to determine if the materials in the water are at an unhealthy level.
Concentration, pH, Molarity, Net Ionic Equation, Acid & Base Theories, Titrations, Indicators, Strong vs Weak, Buffers | High School

Lesson Plan: Acids and Bases Unit Plan

The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach the topic of acids and bases to your students.
Solubility, Solute & Solvent, Intermolecular Forces, Molarity, Net Ionic Equation, Solubility Rules, Beer's Law | High School

Lesson Plan: Aqueous Solutions Unit Plan

We constructed a unit plan using AACT resources that is designed to teach Aqueous Solutions to your students.
Concentration, Molarity | High School

Activity: Particle Level Molarity

In this activity, students are introduced to molarity at the particle level. Students will activate their prior knowledge by demonstrating their understanding of concentration by preparing several Kool-Aid drinks, and then applying that information at the particle level to various models.
Concentration, pH, Molarity, Titrations, Indicators | High School

Demonstration: How to Perform a Titration

In this demonstration, the teacher will show how a titration is set-up and performed. Also, the teacher will utilize different indicators to show how they work and why they are necessary. At the end of the demonstration, the teacher will also explain how to calculate the molarity of the unknown substance.
Concentration, Molarity, Beer's Law | High School

Lab: Beer's Law Discovered

In this laboratory investigation, students will explore the concepts of light absorption, transmittance, and the relationship between absorbance, path length, and concentration of solution.
Molarity | High School

Demonstration: What Is a 1 Molar Solution?

In this demonstration, students will determine the molarity of several different solutions demonstrated by the teacher.
Molarity, Stoichiometry, Limiting Reactant, Chemical Change, Calorimetry, Temperature, Exothermic & Endothermic | High School

Lab: Less Than Zero

In this lab, students will investigate the endothermic reaction between baking soda and HCl. Students will consider stoichiometric ratios, molar concentrations, reaction scale, and calorimetry. The lab starts with a scripted reaction that uses given molar ratios, a glass beaker, and 2-M HCl. They will witness a temperature drop of about 5 to 8 C. Students then adjust the experiment so they can achieve a temperature drop of more than 20 C.
