51 – 68 of 68 Classroom Resources

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

    Lab: Corrosion in Motion

    In this lab, students will expose metal samples to various solutions and observe the amount of corrosion of a period of time.

  • Observations, Physical Change, Solute & Solvent, Intermolecular Forces, Heat, Temperature, Exothermic & Endothermic, Saturated/Unsaturated/Supersaturated | Middle School, High School

    Lesson Plan: Particle Modeling of Hand Warmers

    In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a physical process, such as the crystallization of a solid from a supersaturated solution.

  • Observations, Chemical Change, Conservation of Mass, Chemical Change | Middle School, High School

    Lab: Conservation of Mass

    In this lab, students perform three simple experiments, recording the mass of a substance before and after a reaction. They then explain how the law of conservation of mass was not violated, even if the mass changed.

  • Observations, Phase Changes, Physical Change, Temperature | Elementary School, Middle School

    Lab: Condensation

    In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

  • Observations | Elementary School, Middle School, High School

    Activity: Compare and Contrast

    In this activity, students will use their observation skills to compare and contrast two similar chemistry classroom scenes in order to identify the differences between the two.

  • 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, Chemical Change, Balancing Equations | Middle School, High School

    Lab: Chemical Reactions & Equations

    In this lesson, students will observe a series of reactions, make observations, and then write balanced chemical equations to chemically describe what they observed.

  • 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.

  • Observations, Introduction, Inferences, Scientific Method | Middle School, High School

    Activity: Check Activity

    In this activity, students develop a theory based on evidence they collect from (fake) cancelled checks to come up with a story of how they are related.

  • Observations, Chemical Change, Chemical Change, Acid, Interdisciplinary, Physical Change, Chemical Change | Middle School

    Lab: Break It Down!

    In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.

  • Observations, Inferences, Scientific Method | Middle School, High School

    Activity: Black Box

    In this activity, students will experience how scientists carry out a scientific investigation through inquiry.

  • 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, Physical Properties, Chemical Change, Physical Change, Chemical Change, Temperature, Exothermic & Endothermic | Middle School, High School

    Lab: Observing a Chemical Reaction

    In this lab, students will practice making careful observations and measurements while witnessing a chemical change.

  • Observations, Phase Changes, Combustion, Scientific Method, Experimental Design | Middle School, High School

    Lab: Observing a Candle

    In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.

  • Observations, Chemical Change, Physical Change, Conservation of Mass, Conservation of Mass, Chemical Change, Measurements | Middle School, High School

    Lab: Mass & Change

    In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.

  • Observations, Physical Change, Mixtures | Middle School, High School

    Activity: Magic Bubble

    In this lesson, students will create and interpret particle diagrams that represent elements and compounds at the molecular level. They will also describe the process of dissolving and create particle diagrams that represent mixtures at the molecular level.

  • Observations, Chemical Change, Chemical Change, Mixtures, Acids & Bases | 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.

  • 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.
