  Lab: Kitchen Reaction Mark as Favorite (0 Favorites)

  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.

  Lab: Soap or Fuel Mark as Favorite (0 Favorites)

  In this lab, students will transform vegetable oil into a soft soap and into biodiesel fuel. The two reactions emphasize that the products of a chemical reaction are under the control of the chemist. By noting the relationship of the reaction product to the reactants, students will gain a deeper understanding of the law of conservation of matter.
