Reversible and irreversible change
This resource allows students to explore the concepts of reversible and irreversible change by carrying out tests on simulated substances.
Students can also test what happens to these same substances when water is added or heat is added or removed.
They can make predictions about what will happen, change the variables (substance and temperature), determine if changes are reversible or irreversible and then do a self-evaluative quiz to determine their understanding.
This online resource requires Adobe's Flash technology and therefore won't work on the Apple iPad, which doesn't support that technology.
This resource would suit an introductory lesson on reversible or irreversible change. This resource would support the implementation of a unit of work on reversible and irreversible change such as the Australian Academy of Science unit—Primary Connections—Change detectives.
