UNIT 1: Lesson 1

As you read text pp 4-8, highlight, underline, star content, bracket information; write notes in the margin that will help you answer the following questions over the content covered on these pages:

1. What is matter? Anything that has mass and volume (takes up space)

2. If something is NOT matter, what is it? ENERGY (such as: light, sound, heat…)

3. What is mass? Amount of matter in an object

4. Does the size of an object determine the mass of that object? Not always;large objects could

contain less matter than a smaller sized object (e.g. large Styrofoam block vs small solid

cube of lead [Pb])

5. How could you prove that the invisible, gas mixture air has mass? 1st find the mass of a balloon

(0.005 g); 2nd find the mass of the balloon filled with air (0.010g); SUBTRACT the two

masses and the difference is the mass of the air (0.005 g)

6. What instrument measures mass? Balance (e.g. triple beam balance)

7. Why does the weight of an object change if it’s on a different planetary/celestial location?

Weight is determined by the amount of gravitational pull on an object. Different

planets/celestial objects have different masses; the greater the mass of the planet, the

greater the gravitational pull. The greater the gravitational pull the greater the weight of

the object.

8. What instrument measures weight? Spring scale

9. What is another name for poises or riders positioned on the beams of a balance?Countermasses

10. If the standard, scientific unit (metric) of measurement for mass is the gram (g), what is the

standard, scientific unit of measurement for weight? newton (N)
