Change in Temperature - Exothermic Reaction
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...

Module 7 Revision Guide - Chemistry
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...
Curated OER
Physical and Chemical Reactions - Factors Which Affect Reaction Rate
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...

Thermometric Titration
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...

Thermochemistry
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...

Transition Metals (III)
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...

Entropy and Free Energy
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.

Potential Energy Diagrams
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...
