Many things can change shape. Heat and force can do it. We see changes every day. Some changes can be reversed.

---PAGE---

Ice melts into water. The solid turns to liquid. The shape changes completely. The water can freeze again.

---PAGE---

Clay can be pressed and rolled. It keeps a new shape. It can be changed again. Hands can press it into a ball.

---PAGE---

After that, paper can be folded. Folds make new forms. A flat sheet becomes a crane. Then it can be folded again.

---PAGE---

A balloon changes when air goes in. It grows round and big. When air leaves, it shrinks. Air pushes on the rubber walls.

---PAGE---

Metal can bend with force. A spoon can curve. It may not bend back. Heat can soften the metal too.

---PAGE---

Some changes are slow. Rocks wear down in rivers. Water smooths the rough edges. The river acts like sandpaper.

---PAGE---

Other changes are fast. A rubber band snaps back. Its shape returns quickly. It snaps back to its old size.

---PAGE---

Heat can change some materials forever. Bread toasts and hardens. The change cannot undo. Some changes cannot be reversed easily later on.

---PAGE---

Then cooling can change shape too. Wax hardens when it cools. It keeps the mold's form.

---PAGE---

We can test shape changes at home. We can observe and compare. We learn from simple experiments.

---PAGE---

Changing shape is part of science. It helps us understand matter. We see it all around.
