  • Physical Properties, Mixtures, Molecular Structure, Mixtures | Elementary School, Middle School, High School

    Demonstration: Analyzing Mixtures

    In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.

    Demonstration: Inflating a Balloon with Chemistry

    In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.

  • Observations, Density, Mixtures, Inferences, Mixtures | Middle School, High School

    Demonstration: Density Tubes

    In this demonstration, students will have the opportunity to observe and analyze the density of a solution. Students will interpret their observations as they compare the density of the solution with plastic components.

  • Periodic Table, Naming Compounds, Covalent Bonding, Ionic Bonding, Molecular Formula, Valence Electrons, Subatomic Particles, Lewis Dot Diagrams, Molecular Geometry, Lewis Structures, Ions | Middle School, High School

    Simulation: Ionic & Covalent Bonding

    In the September 2016 simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. Students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.
