• 

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

  Lab: Observing a Chemical Reaction

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

• 

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

• 

  Redox Reaction, History, Oxidation, Reduction, Chemical Change, Observations | 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.

• 

  Chemical Change, Chemical Change, Observations, Acid, 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.

• 

  Gas Laws, Molar Mass, Density, Temperature, Pressure, Volume, Ideal Gas, Physical Change, Observations, Density, Identifying an Unknown, 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.

• 

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

• 

  Periodic Table, Physical Properties, Chemical Properties, Observations, Inferences, Chemical Change, Identifying an Unknown, 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.

• 

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

  Lab: Matter Matters

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

• 

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

• 

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

• 

  Chemical Change, Observations, 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.

• 

  Density, Observations, Inferences, Mixtures, 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.
