Chocolate changes

Topic: 6D Reversible & irreversible changes

Chocolate undergoes many changes from cacao pod to chocolate itself. Some of these changes are reversible and some are irreversible. But which ones?

In this activity children learn about reversible and irreversible changes. They correctly sequence the story of how chocolate is made. They label which of the changes are reversible. They use their knowledge to write a letter to a child in Ghana, explaining how cocoa beans are made into chocolate for Easter eggs.
