Chemical Change, Observations, Acids & Bases, Chemical Change, Mixtures | Elementary School, Middle School, High School
In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
Exothermic & Endothermic, Classification of Reactions, Energy Diagrams, Bond Energy, Activation Energy, Temperature, Chemical Change | High School, Middle School
In the November 2016 simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Students will have the opportunity to compare how energy is absorbed and released in each reaction, and will make a connection between the standard energy diagrams associated with each reaction type.
Le Châtelier's Principle, Establishing Equilibrium, Reversible Reactions, Reaction Rate, Equilibrium Constants, Graphing | High School
In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.
Balancing Equations, Conservation of Mass | Middle School, High School
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.
Balancing Equations, Conservation of Mass, Conservation of Matter, Conservation of Matter, Chemical Change, Chemical Change, Conservation of Mass, Polyatomic Ions, Precipitate | Middle School, High School
In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
