  • Observations, Density, Chemical Change, Balancing Equations, Classification of Reactions, Chemical Change | High School

    Demonstration: Preparation of Hydrogen

    In this demo, students witness a single displacement reaction between zinc and sulfuric acid that produces hydrogen gas. The gas is collected via water displacement and ignited.

  • Density, Physical Properties, Melting Point, Freezing Point, Phase Changes, Physical Change, Molecular Motion, Freezing | Elementary School

    Lesson Plan: Pothole Science

    In this lesson, students investigate how the density and therefore the volume, of water changes when it freezes.

  • Observations, Density, Sublimation, Phase Changes, Physical Change, Temperature | 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.

  • Density, Physical Properties, Identifying an Unknown, Accuracy, Error Analysis | Middle School, High School

    Lab: Density Lab

    In this lab, students determine the density of several liquids and solids. They then identify an unknown metal by determining its density. They then calculate the percent error within the class for a specific sample.

  • Observations, Density, Interdisciplinary, Scientific Method | Elementary School, Middle School

    Lab: Crush's Dilemma

    In this lab, students explore the concept of density. They will examine the density of a plastic sandwich bag compared to water. Students will create their own experiment and investigate factors that affect floating and sinking.

  • Observations, Density, Chemical Change, Density, Inferences | Middle School, High School

    Demonstration: Comparing Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candles to extinguish in order of height. Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.

  • Observations, Density, Physical Properties, Mixtures, Mixtures | Elementary School

    Activity: Color-Works in a Jar

    Students will be using three ingredients to create a liquid color-works mixture in a jar. This is a fun chemistry project to do with young elementary students around the 4th of July or New Year’s Eve to get the children excited about fireworks.

  • Separating Mixtures, Density, Mixtures, Chemical Change, Intermolecular Forces, Physical Change, Intermolecular Forces | Middle School

    Lab: Clean it Up!

    In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.

  • Observations, Density, Inferences, Identifying an Unknown, Measurements, Scientific Method, Error Analysis | High School

    Lab: Colors of the Rainbow

    In this lab, students will practice density calculations and put their calculations to test by creating their own density column.

  • Density, Review, Accuracy, Dimensional Analysis, Measurements, Accuracy, Experimental Design, Error Analysis | Middle School, High School

    Lab: Bowling Ball—Will it Sink or Float in Water?

    In this lab, students will find the density of a bowling ball to determine whether it will sink or float in water.

  • Observations, Density, Mixtures, Chemical Change, Chemical Change, Physical Change, Acid Base Reactions, Mixtures | Elementary School

    Lab: Analyzing a Lava Lamp

    In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.

  • Density, Melting Point, Inferences, Elements, Periodic Table, Matter, Chemical Properties | Elementary School

    Lesson Plan: Mystery Metals

    In this lesson, students will make measurements, calculations, and inferences to help solve a mystery about the identity of an unknown metal.

  • Density, Mole Concept, Dimensional Analysis | High School

    Lab: Moles of Food

    In this lab, students will analyze the nutrition label of a variety of foods to find the amount of specific elements in each serving. Students are asked to evaluate and compare the data in a series of questions, in order to convert the values to moles. This lab gives students the opportunity to see the connection between the chemistry mole concept and everyday foods.

  • Observations, Density, Temperature, Gas Laws, Density, Pressure, Physical Change, Identifying an Unknown, Molar Mass, Ideal Gas, Volume, Error Analysis | High School

    Lab: Molar Mass of Dry Ice

    In this lab, students will use gas laws to calculate the molar mass of dry ice and then use the information to identify the compound that makes up this substance.
