1 – 6 of 6 Classroom Resources

  • Observations, Solubility, Chemical Change, Physical Change, Precipitate, Identifying an Unknown, Solute & Solvent, Graphing, Mixtures, Error Analysis | Middle School, High School

    Lab: Chemicals, Chromatography, and Crime!

    In this lab, students will test “evidence” that has been collected from a crime scene. In order to determine if the victim was poisoned, students will perform a solubility and crystallization test on an unknown powder. Then, students will attempt to identify the culprit by using paper chromatography to analyze the lipstick from the potential criminals.

  • Solubility, Precipitate, Solute & Solvent, Saturated/Unsaturated/Supersaturated | Elementary School, Middle School, High School

    Lab: Winter Crystals

    In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!

  • Chemical Change, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules, Reactions & Stoichiometry | Middle School, High School

    Lab: Predicting Precipitates

    In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.

  • Solubility, Covalent Bonding, Precipitate, Ionic Bonding, Molecular Structure, Solute & Solvent, Saturated/Unsaturated/Supersaturated | Middle School, High School

    Lab: Benzoic Acid Blizzard in a Bottle

    In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.

  • Naming Compounds, Molecular Formula, Precipitate, Ionic Bonding, Ions | Middle School

    Activity: Bond with a Classmate

    In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.

  • Polyatomic Ions, Chemical Change, Conservation of Mass, Precipitate, Conservation of Matter, Balancing Equations, Conservation of Mass, Chemical Change, Conservation of Matter | Middle School, High School

    Activity: Simulation Activity: Balancing Chemical Equations

    In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
