Reversible and Irreversible changes

 

This week is all about how materials change when they are heated or combined with something else. Some changes can be reversed. If you can get back the substances you started the reaction with, that's a reversible reaction. In an irreversible change, new materials are always formed. 

Activities

1. Sort the picture cards into the correct groups - reversible or irreversible. 2. Try mixing the different substances, recording your observations and explanations on the sheet.

Complete the concept map, adding the correct scientific vocabulary. All of the words are linked to changing materials. There are answers for you to check your work.
