Heat, Temperature, Specific Heat, Observations, Molecular Motion | High School, Middle School
Activity: What Makes Something Feel Warm
In this lesson students actively engage in thinking about energy issues in chemistry and the nature of energy (thermal) transfer. The idea that temperature is a measure of heat content will be challenged, and students will be given the opportunity to collect data that will allow them to clearly see that different materials transfer energy at different rates.
Temperature, Molecular Motion, Observations, Inferences | High School, Middle School
Demonstration: What is Temperature?
In this demonstration, students will observe food dye mixing with water at different temperatures.
Conservation of Mass, Exothermic & Endothermic, Chemical Change, Heat, Temperature, Observations, Chemical Change | High School, Middle School
Lab: Kitchen Reaction
In this lab students will observe an endothermic chemical reaction involving baking soda (sodium bicarbonate) and vinegar (acetic acid). Students will investigate the signs a chemical reaction has occurred (gas production, change in temperature). Students will perform the lab in an open system so they can see the change of mass due to gas production. This lab is a lead into the topic of conservation of mass. After the lab is completed, the teacher should do a demonstration of the exothermic reaction Hydrogen peroxide and potassium iodide.

Activity: Is a Picture Worth 1000 Words?
In this activity, students will learn about early chemistry discoveries through a textbook reading as well as from a cartoon.

Lab: Top Secret
In this lab, students will learn about the history of invisible ink and will have the opportunity to compare two types of homemade invisible ink recipes.
Density, Density, Chemical Change, Observations, Chemical Change, Combustion | 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, Phase Changes, Combustion, Observations | Elementary School, Middle School
Demonstration: The Jumping Flame
In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.

Lab: Test Tube Separation
In this lab, students will mix four substances in a test tube and recreate the original four layers through chemical and physical means.
Redox Reaction, Electron Transfer, Chemical Change, Observations, Experimental Design, Scientific Method | High School, Middle School
Lab: Test Tube Geology
In this lab, students will observe a reaction between an iron nail and copper(II) sulfate in a test tube over the course of several days, modeling how a similar reaction occurs to form copper deposits in the earth. Students will also modify the procedures to evaluate how changing a factor of their choice affects the results of the test tube reaction, introducing them to concepts of experimental design. It also introduces students to my version of the Science Writing Heuristic (SWH).

Activity: How Do We Clean Up An Oil Spill
In this activity, students simulate an oil spill and test different materials’ ability to “clean” the oil spill.
Combustion, Chemical Change, Catalysts, Acid Base Reactions, Chemical Change, Balancing Equations, Classification of Reactions, Observations, Chemical Change | High School, Middle School
Demonstration: Stop & Go Gases
In this demonstration, students will witness the ability of carbon dioxide to extinguish a flame and oxygen to feed a flame. They will also be introduced to the concept of catalysts. This demonstration could also be used as an opportunity to practice writing and balancing equations and classifying chemical reactions.

Activity: Engineering Project
In this activity, students work together in a small team in order to solve a problem and achieve a common goal. Students will need to work collaboratively in order to be successful.
