26 – 35 of 35 Classroom Resources

  • Observations, Density, Interdisciplinary, Scientific Method | Elementary School, Middle School

    Lab: Crush's Dilemma

    In this lab, students explore the concept of density. They will examine the density of a plastic sandwich bag compared to water. Students will create their own experiment and investigate factors that affect floating and sinking.

  • Observations, Phase Changes, Physical Change, Temperature | Middle School, Elementary 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 | High School, Elementary School, Middle 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, 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 | 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, pH, 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 | High School, Middle 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, Chemical Change, Acids & Bases, Chemical Change, Mixture | High School, Middle School, Elementary 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.
