Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

Melting and burning might seem like opposites, but both exist as common examples of exothermic reactions. Scholars work with three different exothermic chemical reactions to determine the enthalpy changes. They measure and mix chemicals,...

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...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

For this thermometric titration worksheet, students titrate hydrochloric acid with sodium hydroxide to determine the concentration of hydrochloric acid. They measure the change in temperature of the solution, plot their data and use the...

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 discuss transition metals, where they are located on the periodic table, some of the element in the group, and some characteristics of the group. They work in groups to conduct an experiment in which they mix transition metals...

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 entropy learning exercise, students define entropy and determine if reactions are exothermic or would occur spontaneously. This learning exercise has 10 problems to solve.

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...
