  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.

  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.

• 

  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).
