  • Conservation of Mass, Matter | High School

    Lab: Matter Matters

    In this lesson, students will investigate the Law of Conservation of Mass.

  • Conservation of Mass, Conservation of Mass, Measurements | Middle School, High School

    Lab: Mass & Change

    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

    Demonstration: Inflating a Balloon with Chemistry

    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.

  • Balancing Equations, Conservation of Mass | High School, Middle School

    Simulation: Balancing Chemical Equations

    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.
