Concentration, Solute & Solvent, Molarity  High School
Activity: Simulation Activity: 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 stepbystep 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.
