This quiz takes a look at some reversible and some irreversible changes. Reversible changes to a material can be changed back but irreversible changes are more permanent
Changing materials is also transforming substances. Think about water - when it is really cold it changes into ice, or when it is heated it changes into steam. Other substances can also be changed. One of the most fascinating aspects of science is the way that materials can be altered. Different substances react together in interesting ways, sometimes changing into new materials. Applying heat, cooling or adding water - all of these can change materials.
Test your knowledge of reversible and irreversible changes by trying this science quiz.
