1 – 10 of 10 Classroom Resources

  • Physical Properties, Solubility, Polarity, Covalent Bonding, Intermolecular Forces, Molecular Geometry, Electronegativity | High School, Middle School

    Activity: The Chemistry of Water Video Questions

    In this lesson, students will watch a video and answer questions about how the molecular geometry and polarity of water give rise to many of its unusual physical properties, including its relatively high boiling point and its ability to dissolve some substances but not others.

  • Physical Properties, Concentration, Chemical Properties, pH | Middle School

    Activity: Would You Drink it?

    In this activity, students are provided with data regarding the water quality at multiple locations throughout a city. Students will determine which location should be prioritized for cleaning of contaminates. Students will utilize Claim Evidence and Reasoning (CER) to develop a claim that is supported by the data provided.

  • Mixtures, Molecular Structure, Electromagnetic Spectrum | High School, Middle School

    Activity: What are Pigments? Video Questions

    In this activity, students will watch a video and answer related questions about the chemistry of pigment molecules and how they are used to give paints their specific color. During the video, students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

  • Mixtures, Intermolecular Forces, Polymers, Molecular Structure, Solute & Solvent, Intermolecular Forces, Electromagnetic Spectrum | High School, Middle School

    Activity: What is Paint? Video Questions

    In this activity, students will watch a video and answer related questions about the composition of paint. During the video, students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.

  • Solubility, Solute & Solvent, Intermolecular Forces | High School, Middle School

    Activity: Advanced Modeling of the Dissolving Phenomenon

    In this activity students build a model of sodium chloride based on their own knowledge of ionic compounds. Then they construct a model of the interactions between water and their salt model to develop an understanding of what caused the salt to dissolve. After refining their models based upon class discussions and critiques, students then construct a model of the interaction between salt and a different solvent, alcohol. Using their models, students make predictions as to which solvent (water or alcohol) would be better at dissolving the salt. Finally students design an experiment to test their prediction. As an extension, students are asked to use their solubility models to explain why calcium carbonate will not dissolve in water, even though it is also an ionic compound.

  • Solubility, Solute & Solvent, Intermolecular Forces | High School, Middle School

    Activity: Basic Modeling of the Dissolving Phenomenon

    In this activity, students explore the process of salt dissolving in water using cut-outs of ions and water molecules to model interactions between them. They then use their model to make a prediction about the relative solubility of salt in isopropyl alcohol compared to the solubility in water and design an experiment to test their prediction.

  • Mixtures, Molecular Structure, Electromagnetic Spectrum | High School, Middle School

    Video: What are Pigments? Video

    This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

  • Mixtures, Intermolecular Forces, Molecular Formula, Polymers, Molecular Structure, Solute & Solvent, Intermolecular Forces, Electromagnetic Spectrum | High School, Middle School

    Video: What is Paint? Video

    This video investigates the composition of paint, while analyzing the fundamental chemistry principles of its main components. Students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.

  • Mixtures, Solubility, Intermolecular Forces, Polarity, Solute & Solvent, Intermolecular Forces, Molecular Geometry | High School, Middle School, Elementary School

    Animation: Solubility Animation

    In an animation, students will have an opportunity to visualize on the particulate level how solubility works. Examples of ionic compounds and a polar covalent compound show how when water is attracted to charged parts, they dissolve, and when they're not attracted to charged parts they stay solid. **This video has no audio**

  • 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.
