Reversible & Irreversible Changes
Directions: As you have learned, matter can change state. After matter changes state, some of the changes are reversible and some of the changes are irreversible. A reversible change means that you can change the state back to the state it was originally in. For example, ice is a solid. When you apply heat to ice it turns into a liquid. If you put the water back into the freezer, the water will turn back into ice again. This is an example of a reversible change. Some changes, however, are irreversible. An irreversible change happens when matter cannot be changed back to its original state.
In this activity, you will be exploring reversible and irreversible changes. Use the "Reversible Changes" (click link) simulation to complete the "Irreversible or Reversible Changes" worksheet (click link).
As you complete the activity, think about these important questions:
After you have printed and completed the "Irreversible or Reversible Changes" worksheet, bring the completed worksheet and your "Action Plan" to the teacher to get it signed.
