26 – 38 of 38 Classroom Resources

  • Observations, Chemical Change, Inferences, Reduction, Redox Reaction, Classification of Reactions, Chemical Change, Oxidation, Electron Transfer, Electrons, Ions | Middle School

    Lesson Plan: One Tube Reaction

    In this lesson, students will observe a chemical change involving oxidation and reduction.

  • Observations, Chemical Change, Interdisciplinary, Physical Change, Reaction Rate, Reaction Rate, Chemical Change | Middle School

    Lab: Chemical Weathering in Geology

    In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

  • Chemical Change, Interdisciplinary, Molecular Formula, Conservation of Mass, Balancing Equations, Conservation of Mass, Reversible Reactions, Chemical Change, Photosynthesis | Middle School

    Lesson Plan: The Building Blocks of Photosynthesis

    In this lesson, students will use colored blocks to represent the elements in photosynthesis and illustrate how they are broken down and reassembled to create glucose.

  • Oxidation, Reduction, Redox Reaction, Chemical Change, Oxidation, Electron Transfer, Electrons | Middle School

    Lesson Plan: Old Rusty

    In this lesson, students will explore the concept of oxidation of metals by creating designs on fabric or paper using rusty objects.

  • Observations, Reaction Rate, Reaction Rate, Chemical Change | Middle School, Elementary School, High School

    Demonstration: Simple Kinetics

    In this demonstration, students will see that different food dyes react with bleach at different rates.

  • Polymers, Molecular Structure, Polymers, Chemical Change, Molecular Structure , Chemical Bond, Monomer, Monomer | Middle School

    Lesson Plan: The Power of Polymers

    In this lesson students will use lab activities and discussion to explore polymers and their use in 3D printing, with an emphasis on the benefits of 3D printing in automotive manufacturing.

  • Polymers, Polymers, Chemical Change, Chemical Bond | Middle School, High School

    Demonstration: Turn Milk into Plastic

    In this demonstration, students will observe the process of making a polymer, casein plastic, from the casein protein found in milk.

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

    Lab: Predicting Precipitates

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

  • Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Elementary School, Middle School

    Demonstration: Investigating Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. 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 candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.

  • Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Elementary School, Middle School

    Lab: Rocket Challenge

    In this lab, students will have the opportunity to construct a rocket, with the challenges of both designing it and preparing a chemical reaction for its “fuel” in order to propel the rocket over the furthest distance. Students will investigate available materials, quantities and ratios during allotted planning and testing phases. Student will record their plans, modifications and designs during the process. The lab will culminate with a competition amongst students to see whose rocket will travel the longest distance.

  • Density, Chemical Change, Density, Chemical Change | Elementary School, Middle School, High School

    Demonstration: Fire Extinguisher

    In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.

  • Observations, Phase Changes, Combustion, Chemical Change | Elementary School, Middle School

    Demonstration: The Jumping Flame

    In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.

  • Observations, Chemical Change, Acids & Bases, Chemical Change, Mixtures | Elementary School, Middle School, High School

    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.
