Theme

What is the theme or topic to be presented?

Exothermic and Endothermic reactions as demonstrated through the creation of 

hand warmers and ice cream.

Learning Objectives

Students will be able to: 

• Apply the processes of exothermic and endothermic reactions to the 

creation of useable objects.

• Explain the exothermic and endothermic reactions involved in the making

of ice cream and hand warmers.

Chemistry Standards:

Year 11 4.4 Design and carry out experiment to describe the exothermic reaction and endothermic reaction

Key Vocabulary:

• Exothermic

• Endothermic

• Molality 

Ideas for Building Materials (per student):

Additional materials are necessary for the “lowering the freezing point” 

experiment that enhances this lesson, the materials list for that activity can be 

found in the lesson overview below.
