What's the Matter?

Earth Science - Science

When you tear a piece of paper in half, is that a physical change or a chemical change? This worksheet teaches your student about matter, mass, and property, then challenges him to identify whether a change is physical or chemical. An exciting experiment with baking soda, vinegar, and a balloon reinforces the concepts.
