ALL ABOUT PLASTIC

Have you ever watched an ice cube melt or a candle burn and wondered why those changes look so different? Matter can change in many ways, but not all changes create something new. With this worksheet, you explore how to tell the difference between physical and chemical changes using real-life examples. Each activity helps you observe clues, think carefully, and identify what type of change is happening. As you learn, you begin to understand how matter behaves in the world around you.

Your journey begins with physical changes. These are changes that alter the form of a substance but keep its identity the same. Activities guide you to explore examples like breaking chalk, boiling water, or dissolving sugar. You’ll notice how the substance remains itself, even if it looks or feels different. This helps you recognize that physical changes are often reversible. You start building confidence in identifying them.

Next, you investigate chemical changes—transformations that create new substances. Worksheets help you observe signs such as bubbling, color changes, heat release, or unexpected smells. You’ll explore examples like rusting metal, baking bread, or burning wood. You begin to see that chemical reactions rearrange particles in ways that cannot easily be undone. This strengthens your ability to spot chemical change in action.
