  Lab: Less Than Zero Mark as Favorite (36 Favorites)

  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.

  Le Châtelier's Principle, Establishing Equilibrium, Reversible Reactions, Reaction Rate, Equilibrium Constants, Graphing | High School

  Lab: Dynamic Equilibrium Simulation Mark as Favorite (33 Favorites)

  In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.

  Simulation: Balancing Chemical Equations Mark as Favorite (40 Favorites)

  The simulation for the September 2014 issue comes from PhET and helps students practice balancing chemical equations. AACT helped fund the conversion of this popular simulation into a format that is compatible with all devices, including iPads. PhET provides teacher’s guides for many of their simulations, and teacher-generated activities that can accompany the simulations.
