Chapter 9 Lesson 1 Describing Matter Pages 232 -251

Please Do Now! In the blank space at the top of your paper, write three things that take up space. Share your list with a partner. Share out with the class.

1. Anything that has mass and takes up space is matter.

2. The amount of matter in an object is the object’s mass. Less mass More mass

3. Matter takes up space, so matter has volume.

4. Matter has many characteristics, or properties that can be used to describe it. d n u ro bla ck ma gn etic

5. To measure mass scientists use a tool called a balance.

6. The ability of a material to dissolve in liquids is another property of some types of matter.

7. Properties that can not be seen can still be measured.

Thinking Cap! On your paper in the margin, please write what you think are two properties of matter that you can’t see, but can still be measured. Share with your partner. Add one more to your list that you heard in the class discussion.

8. Wood floats on water because wood has the property of buoyancy.

9. The different forms that matter can take are called states of matter.

10. The state of matter that has a definite shape and a definite volume is the solid state.

11. The particles in a solid are packed tightly, often in a regular pattern.

12. When matter in the liquid state is moved from one container to another, it keeps the same volume but takes the shape of its container.

13. Oxygen is a gas because it takes the shape and volume of the container in which it is placed.

14. Particles in a gas move about freely.

15. When you use something again, you reuse matter.

16. Matter can end up in landfills or oceans.

17. Matter can be recycled, or made into something else.

18. Metal, paper, plastic, and glass can be recycled.

Exit Question 19. Do you think you can describe an object without using its properties?

19. You can’t describe an object without using its properties because anything that is used to describe an object is one of its properties. The shape, mass, volume, length, color, and other characteristics are all properties.
