Classroom Resources: Reactions & Stoichiometry
176 – 179 of 179 Classroom Resources
Conservation of Mass, Conservation of Mass, Measurements | Middle School, High School
In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.
Observations, Chemical Change, Acids & Bases, Chemical Change, Mixture | High School, Middle School, Elementary 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.
Reaction Rate, Reversible Reactions, Le Châtelier's Principle, Establishing Equilibrium | High School
In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.
Balancing Equations, Conservation of Mass | High School, Middle 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.
