You are going to read the text aloud. You have 1.5 minutes to read the text silently, and then be ready to read it aloud. Remember that you will not have more than 2 minutes for reading aloud.
Everything in the universe is made of matter. Matter cannot be created or destroyed, but it can change its form. Some changes in matter are physical changes. That means that matter changes its shape or appearance, but it is still the same kind of matter. It doesn't become a different kind of matter. For example, imagine that you take a piece of ice out of the freezer and put it into a cup. What happens to the ice if you leave it out of the freezer? It melts and turns into water. It is still the same matter, but it has changed from a solid into a liquid. When you warm up the ice, you are not destroying it; you are just changing its form. And if you put that water back in the freezer, it will freeze again and change its form from a liquid to a solid. |
