Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

In this reactions worksheet, students use graphs showing reaction progress to determine if the reaction is exothermic or endothermic, the activation energy, and the enthalpy of change. This worksheet has 1 graph, 7 short answer, and 16...

Through critical thinking, students realize that spontaneous events happen in a certain order. This lesson presents an examination of the Second Law of Thermodynamics using a thought story, rubber band inquiry, discrepant event and lecture.
