Exothermic and Endothermic Reactions
Pupils’ starting point, prior or prerequisite knowledge:
Students should know that reactions give out heat. They may have come across those that get cooler, but unlikely. These terms are new, and some may know them, but it is not expected that they do.
Possible misconceptions about:
Endo/exo wording – remember by ex-it (ex-o); en-ter (en-do)
Detail of key science concepts or skills:

Endothermic reactions: require heat – so the overall temperature will go down
Exothermic reactions: give out heat – so the overall temperature will go up

Inquiry question/s:
Chemical reactions may give out, or require heat. What are these types of reaction called?
How does a handwarmer work?

Pupil learning objectives/outcomes/success criteria: By the end of the lesson the pupils will be able to:
To understand what exothermic and endothermic reactions are

To draw a results table
To safely carry out a practical, recording correct observations.
To be able to name exothermic and endothermic reactions.
