  Conservation of Mass, Exothermic & Endothermic, Chemical Change, Heat, Temperature, Observations, Chemical Change | High School, Middle School

  Lab: Kitchen Reaction Mark as Favorite (18 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.

  Exothermic & Endothermic, Energy Diagrams, Heat, Temperature, Chemical Change | High School

  Lab: Exothermic and Endothermic Lab Mark as Favorite (57 Favorites)

  In this lab, students determine whether mixing two chemicals is endothermic or exothermic. One is a physical change, one is a chemical change.

• 

  Kinetic Molecular Theory, Temperature, Heat, Temperature | Middle School, High School

  Lab: Mega Marshmallows Mark as Favorite (46 Favorites)

  In this lab, students will investigate the Kinetic Molecular Theory and particle motion while experimenting with a marshmallow. Students will observe how an increase in kinetic energy will cause particles to increase in motion. This concept will be extended into a discussion about additional real world thermal expansion examples.
