1 – 3 of 3 Classroom Resources

  • Sublimation, Gas Laws | High School

    Demonstration: Ideal Gas Law using Carbon Dioxide

    In this demonstration, students observe dry ice sublime while the CO2 gas fills a balloon. They then calculate the moles and volume of CO2 produced.

  • Sublimation, Chemical Change, Pressure, Phase Changes, Physical Change, Boiling Point, Chemical Change | Middle School

    Lesson Plan: Dry Ice

    In this lesson, students will investigate how dry ice undergoes a phase change from solid to gas, skipping the liquid phase under normal temperature and pressure.

  • Observations, Density, Sublimation | Middle School, High School

    Lab: Dry Ice (High School)

    In this lab, students perform several small experiments using dry ice and record their observations.
