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,...

In this energy and matter worksheet, students define 28 terms related to moles, matter, energy, the Law of Conservation of Energy, mass, properties of matter and states of matter.

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 answer twenty multiple choice questions about heat, enthalpy changes, thermal, mechanical and electrical energy and the laws of thermodynamics.

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...

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge in...

In this online interactive anatomy crossword puzzle activity, students use the 8 clues to find the appropriate answers to complete the word puzzle.

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...
