    Lab: Chemical and Physical Changes

    In this lab, students will observe and analyze a number of examples in order to determine if a chemical or physical change occurred.

  • Observations, Physical Change, Chemical Change | Elementary School

    Lab: Gummy Bear Investigation

    In this lab students will write a plan then conduct an experiment using the scientific method to observe the physical and chemical changes that a gummy bear will experience when placed in a solution of their choice.

  • Separating Mixtures, Physical Change, Chemical Change, Chemical Change, Exothermic & Endothermic | Elementary School

    Lab: Super Suds

    In this lab, students will investigate an endothermic chemical reaction by combining baking soda, hand soap and citric acid. The students will be tasked with differentiating between chemical and physical changes during this experiment.

  • Physical Properties, Physical Change, Chemical Change | Elementary School

    Lab: What's the Fizz?

    In this lab, students will make a lemon fizzy drink. Students will discuss what happens when things are mixed together.

  • Physical Change, History, Periodic Table | Elementary School, Middle School, High School

    Video: Gold Video

    In this video, Sam Kean tells stories about gold.

  • 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.

  • 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 Change, Identifying an Unknown, Chemical Change, Acid Base Reactions | Middle School

    Lab: Is It a Hoax

    In this lab, students will perform tests on the physical and chemical properties of different substances to determine the identity of the unknown.

  • Physical Change, Intermolecular Forces, Polarity, 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.

  • Physical Change, Intermolecular Forces, Molecular Motion, Polarity, Intermolecular Forces, Molecular Motion | High School

    Activity: Simulation Activity: Comparing Attractive 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, Density, Physical Change, Chemical Change, Balancing Equations, Chemical Change, Physical Change, Mixtures | High School

    Lab: The Lovely Lava Lamp

    In this lab, students add food coloring to a mixture of oil and water and record their observations. They then add an Alka-Seltzer tablet, record their observations and answer a series of questions about the chemical and physical changes that took place.

  • Density, Gas Laws, Density, Pressure, Phase Changes, Physical Change, Temperature, Sublimation, Interdisciplinary, Mole Concept, Dimensional Analysis, Measurements, Ideal Gas, Volume | 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, Separating Mixtures, Physical Properties, Physical Change, Chemical Change, Scientific Method, Chemical Properties, Mixtures, Experimental Design | Middle School, High School
