Heavy objects sink and light objects float.

How would you prove this? (Don't forget to mention density in your explanation.)

2

Draw the particles in each of the three states of matter.

3

How do you find the mass of a box of crayons?

You can use a balanced beam. When the pans contain exactly the same mass the beam will be in balance. You can place an object in one pan and standard weights in the other to find what the object weighs.

4

Would you use a paper bag or plastic bag to construct a raincoat? Why? Support your answer with evidence.

Think and Explain!

5

The more matter an object has, the greater its _________________ will be.

mass

6

Measuring the weight of a pencil can be done in ________________?

Grams

7

Measuring the mass of a small child can be done in _________________?

Kilograms

8

Everything in the world that takes up space and has mass is made of_____________?

Matter

9

All matter has __________________ because all matter takes up space.

Volume

10

Weight

The measure of the pull of gravity on an object.

11

Density

Will tell us if an object will sink or float.

12

How can matter be changed?

Heating and Cooling

13

Volume of a solid object is measured in _______________?

Cubic cm

14

How do you find the volume of a solid?

Length x Width x Height

15

Would 20 mL quench your thirst? Why or why not?

Think and Explain.

16

Buoyancy

Buoyancy is the upward force we need from the water to stay afloat, and it's measured by weight. Buoyant forces are why we feel so much lighter when we're in a swimming pool or bathtub

17

Measure the volume of the water in milliliters in each cylinder.

19

What is evaporation?

It is the process whereby atoms or molecules in a liquid state (or solid state) gain sufficient energy to enter the gaseous state. When a liquid changes into a gas because of heat.

20

Find the original volume of the cylinder. Then, find the liquid volume of the rock.
What is the liquid volume of the rock?

21

If a round ball of play-dough has a volume of 540 cubic cm, then the play-dough is rolled out flat, will it still have the same volume of 540 cubic cm? Why?

Think and Explain (Yes)

22

What is volume?

How much space something takes up.

23

What is density?

The amount of matter in a given space.

24

What is a physical change?

Causes a change in the state of matter, but doesn't change matter itself. Example: Water cooled would produce ice. Ice heated would produce water.

25

What is condensation?

When water changes from a gas to a liquid.

26

What is matter made up of?

Atoms
