  • Freezing Point, Phase Changes, Freezing Point Depression | High School, Middle School

    Lab: Freezing Ice Cream

    In this lab, students will investigate changing states of matter, chemical reactions, and the properties of ice and salt while creating their own ice cream.

  • Observations, Physical Properties, Phase Changes, Matter | Elementary School

    Activity: Matter Can Taste Good!

    In this activity, students will be introduced to the general differences and organization of particles in each state of matter: solid, liquid and gas. They will have the opportunity to compare the samples and then will identify each state of matter during an edible activity.

  • Phase Changes, Conservation of Matter, Polymers, Chemical Change | Elementary School

    Lesson Plan: Making Slime

    In this lesson, students explore the science behind chemical reactions as well as the processes used by chemical engineering principles to develop new materials. The idea that mixing two substances can result in an explosion, the release of gas, and the formation of an entirely new substance is both fascinating and mysterious to most young students.

  • Observations, Melting Point, Phase Changes, Introduction, Physical Change | Elementary School

    Lesson Plan: Let's Get Physical About Water

    In this lesson, students will learn about the phase changes of matter. During the course of two days students will perform several short experiments in order to change the state of water and they will record their observations.

  • Molecular Motion, Temperature | Middle School, High School

    Demonstration: What is Temperature?

    In this demonstration, students will observe food dye mixing with water at different temperatures.

  • Freezing Point, Phase Changes, Physical Change, Temperature | Middle School

    Lab: Lemon Ice

    This activity explores the interaction between salt and water (ice) as a way to further investigate their impact on the state of matter of a substance. Students will use salt and ice to create a slushy lemonade drink without the use of a freezer. They will learn through this hands-on experiment how salt and ice can rapidly cool a liquid.

  • Physical Properties, Phase Changes, Introduction, Molecular Motion, Matter | Elementary School

    Lesson Plan: Introducing States of Matter

    In this lesson, students will investigate particle behavior in different forms of matter: solid, liquid and gas. Students will have an opportunity to examine a model of the particles in the different states of matter and will also participate in a kinesthetic demonstration of matter. They will also learn what makes the states of matter different from one another when changing from one form to another.

  • Physical Change, Intermolecular Forces | High School

    Activity: Intermolecular Forces Activity

    In this activity, students will represent molecules and energy to investigate the different types of intermolecular forces.

  • Molecular Motion, Molecular Motion | High School

    Activity: The Molecule Dance

    In this activity, students will explain bond and molecular movements by mimicking molecular motion with their own movements.

  • Intermolecular Forces, Physical Change, Intermolecular Forces | High School

    Simulation: Intermolecular Forces

    In this activity, students will use a simulation to investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the activity, they will relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).

  • Observations, Phase Changes, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: The Jumping Flame

    In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.

  • 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.

  • Observations, Physical Properties, Melting Point, Phase Changes, Scientific Method | Elementary School

    Lab: Ice Cube Race

    In this lab, students will investigate what factors can influence the change in state of matter from a solid to a liquid. They will have the opportunity to make a hypothesis and participate in the design and completion of an experiment.

  • Heating Curve | Middle School, High School

    Simulation: Heating Curve of Water

    In this simulation, students will investigate qualitatively and quantitatively what happens as water changes states.

  • Physical Change, Phase Diagram, Intermolecular Forces | High School

    Lab: Heating & Cooling Curve

    In this lab, students will create a phase change graph by adding and removing heat to observe and record data during actual phase changes.

  • Intermolecular Forces, Boiling Point, Heat of Vaporization | High School

    Lab: Heat of Vaporization

    In this lab, students test whether a substance’s heat of vaporization is determined by its molar mass, the strength of its intermolecular forces, or both.

  • Melting Point, Freezing Point, Phase Changes, Physical Change, Acids & Bases | Middle School

    Lesson Plan: Stearic Acid

    In this lesson, students investigate how stearic acid undergoes a phase change from solid to liquid and back from liquid to solid. Temperature readings will be collected at one-minute intervals once the acid melts, the heat escapes, and the acid cools. Students are introduced to the idea that energy loss does not always result in a continuous temperature drop.

  • Separating Mixtures, Mixtures, Solubility, Phase Changes, Physical Change | Middle School

    Lab: A Solution to Your Mix-up

    In this lab, students will perform a step by step process of mixing and separating substances based on their states and solubility in order to solve a problem.

  • Mixtures, Intermolecular Forces, Intermolecular Forces | High School

    Lesson Plan: Fuel Line Antifreeze

    In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).

  • Physical Properties, Solubility, Freezing Point, Phase Changes, Physical Change, Solute & Solvent, Freezing Point Depression, Freezing Point | Elementary School

    Lesson Plan: Salting Roads in Winter

    In this lesson, students investigate how the freezing point of water changes when salt is added.
