• 

  Density, Observations, Chemical Change, Lab Safety, Combustion | High School

  Demonstration: Fish Tank Carbon Dioxide

  In this demonstration, students watch as a reaction between baking soda and vinegar produces carbon dioxide, which then causes lit candles to extinguish.

• 

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

  Lesson Plan: Salting Roads in Winter

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

• 

  Review, Density | High School, Middle School

  Activity: Round Robin

  In this activity, students solve problems on a series of sheets shared in a group.The activity can be extended beyond the topics of temperature and density. This lesson accompanies an article in Chemistry Solutions.

• 

  Kinetic Molecular Theory, Ideal Gas, Gas Laws, Volume, Temperature, Graphing, Accuracy, Error analysis | High School

  Lab: Finding Absolute Zero

  In this lab, students will experimentally determine the value for absolute zero in degrees Celsius.

• 

  Introduction, Interdisciplinary | High School

  Activity: Experimental Design using Science and Engineering Practices

  In this activity, students will read a short story about an experiment that was conducted about an everyday question. Then the student will decide if and how the experimenter followed the scientific method. Then they will consider their own everyday questions and propose a way to answer them experimentally.
