    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, Physical Change, Chemical Change, Reversible Reactions | High School

    Lab: Breath Test

    In this lab, students investigate whether chemical reactions can happen only in one direction, or whether they can be "undone."

  • Observations, Physical Properties, Introduction, Polymers | Elementary School

    Activity: Bouncy Ball

    In this activity, students explore the chemical reaction between borax and glue, creating a polymer ball. The properties of the polymer ball will be analyzed and compared to a store bought bouncy ball.

  • 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, Density, Mixtures, Physical Change, Chemical Change, Chemical Change, Acid Base Reactions, Mixtures | Elementary School

    Lab: Analyzing a Lava Lamp

    In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.

  • Observations, Inferences, Chemical Change, Classification of Reactions, Chemical Change, Reduction, Redox Reaction, 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 Change, Inferences, Physical Change, Solute & Solvent, Identifying an Unknown, Chemical Change | Elementary School

    Lesson Plan: Alien Invasion?

    In this lesson, students will explore both physical and chemical changes as they try to help the Department of Homeland Security analyze and identify materials found in a mysterious capsule. Students will examine and observe an unknown object (a frozen water balloon) as it changes (melts). They then mix combinations of everyday substances to observe chemical changes.

  • Observations, Scientific Method, Error Analysis, Experimental Design | High School

    Lab: Airplanes

    In this lab, students will design a procedure to test for the intended outcome of a longest flight.

  • Observations, Physical Properties, Physical Change, Chemical Change, Chemical Change, Exothermic & Endothermic, Temperature | 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, Inferences, Scientific Method | High School

    Demonstration: Observations vs. Inferences

    In this demonstration, students will learn the the difference between observation and inferences.

  • Observations, History, Chemical Change, Reduction, Redox Reaction, Oxidation | High School

    Demonstration: Nitric Acid Acts Upon Copper

    In this demonstration, students will hear a story about Ira Remsen and watch a demonstration that recreates her first experiment reacting nitric acid with a copper penny.

  • Observations, Acid, Chemical Change, Chemical Change, Chemical Change | Elementary School

    Lab: My Pennies

    In this lab, students will investigate how an acidic, vinegar based solution can help to get “dirty” pennies clean. Students will observe chemical change and investigate real-world connections to this lab.

  • Observations, Density, Gas Laws, Density, Pressure, Physical Change, Temperature, Identifying an Unknown, Ideal Gas, Molar Mass, Volume, Error Analysis | High School

    Lab: Molar Mass of Dry Ice

    In this lab, students will use gas laws to calculate the molar mass of dry ice and then use the information to identify the compound that makes up this substance.

  • Observations, Chemical Change, Chemical Change, Reaction Rate, Le Châtelier's Principle, Limiting Reactant, Chemical Change, Indicators, Acid Base Reactions | High School

    Demonstration: Milk of Magnesia Magic

    In this demonstration, students will observe a color change in a milk of magnesia solution as vinegar is added.

  • Observations, Physical Properties, Inferences, Periodic Table, Identifying an Unknown, Chemical Change, Chemical Properties, Error Analysis | High School

    Lab: Metal, Non-Metal, or Metalloid

    In this lab, students will classify several samples of elements as metals, nonmetals, or metalloid based on their physical and chemical properties.

  • Observations, Conservation of Matter, Conservation of Mass, Chemical Change, Balancing Equations, Conservation of Mass, Chemical Change, Matter, Conservation of Matter, Experimental Design, Predicting Products | High School

    Lab: Matter Matters

    In this lesson, students will investigate the Law of Conservation of Mass.

    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, Acids & Bases, Chemical Change, 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.
