7. How Does It Measure Up?
Using the same three blocks, find the mass and volume of each of the blocks using a ruler and an electronic balance.

8. Mass and Weight Quick Lab
We are going to do a quick lab that helps us investigate the relationship between mass and weight.

9. Finding Volume by Displacement.
Let’s review a lab we did earlier this year. We are going to use a graduated cylinder to find the volume of an irregular solid object.

10. Density Dependent Demo
I have two beakers each filled with 100 mL of water. I’m going to add a drop of food coloring to each beaker.

11. Density Dependent Demo
I have two beakers each filled with 100 mL of water. I’m going to add a drop of food coloring to each beaker.
Next, I’m going to add about 100 mL of cooking oil to one of the beakers. Can I have a volunteer stir this beaker? What is going to happen to the oil and water?

12. Density Dependent Demo
I have two beakers each filled with 100 mL of water. I’m going to add a drop of food coloring to each beaker.
Next, I’m going to add about 100 mL of cooking oil to one of the beakers. Can I have a volunteer stir this beaker? What is going to happen to the oil and water?
The cooking oil will float on the water.

13. Density Dependent Demo

Next, I’m going to add about 100 mL of cooking oil to one of the beakers. Can I have a volunteer stir this beaker? What is going to happen to the oil and water?
The cooking oil will float on the water.
I now am going to add 100 mL of corn syrup to the second beaker. Can I have a volunteer stir this beaker? What do we think is going to happen to the corn syrup and water?

14. Density Dependent Demo
Next, I’m going to add about 100 mL of cooking oil to one of the beakers. Can I have a volunteer stir this beaker? What is going to happen to the oil and water?
The cooking oil will float on the water.
I now am going to add 100 mL of corn syrup to the second beaker. Can I have a volunteer stir this beaker? What do we think is going to happen to the corn syrup and water?
The corn syrup will sink to the bottom.

15. Density Dependent Demo
Next, I’m going to add about 100 mL of cooking oil to one of the beakers. Can I have a volunteer stir this beaker? What is going to happen to the oil and water?
The cooking oil will float on the water.
I now am going to add 100 mL of corn syrup to the second beaker. Can I have a volunteer stir this beaker? What do we think is going to happen to the corn syrup and water?
The corn syrup will sink to the bottom.
Why does the corn syrup sink and the cooking oil float when added and stirred with water?

16. Density Dependent Demo
Why does the corn syrup sink and the cooking oil float when added and stirred with water?
The cooking oil is less dense than water so it will float on top of the water. The corn syrup is more dense than water so it will sink below the water.

17. Comparing Buoyancy Exploration Lab Demo
Let’s make a density column of five liquids and use it to explore the buoyancy of different objects.

18. How Much Mass? Quick Lab
Let’s do one more quick lab to explore the relationship between mass, volume, and types of matter.

19. Introduction EQ: What properties define matter?
Welcome to the lesson, "Introduction to Matter," where you'll explore what matter is, and how some of matter's properties can be measured.
The vocabulary words for this lesson are matter, weight, density, mass, and volume.

20. Vocabulary Matter: Anything that has mass and takes up space
Mass: A measure of the amount of matter in an object
Weight: A measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe
Volume: The amount of space that an object takes up, or occupies
Density: The ratio of the mass of a substance to the volume of the substance

43. Another Look at Volume
On pages , study the pictures of the lunch box and the locker. Think about how a rectangular solid, such as a block of wood, and an empty container, like the locker or lunch box, are similar and different.

44. Another Look at Volume
On pages , study the pictures of the lunch box and the locker. Think about how a rectangular solid, such as a block of wood, and an empty container, like the locker or lunch box, are similar and different.
The volume of a solid block is the amount of space occupied by the object. When thinking the volume of an ‘empty’ container, such as the lunchbox or the locker, you are really dealing with the capacity of the container- how much matter it can hold, not how much matter it is made of.

The volume of a solid block is the amount of space occupied by the object. When thinking the volume of an ‘empty’ container, such as the lunchbox or the locker, you are really dealing with the capacity of the container- how much matter it can hold, not how much matter it is made of.
We use graduated cylinders in this way. We don’t think about how much space the graduated cylinder takes up, but the volume of space inside the graduated cylinder.

46. Displacement
Remember that with the water displacement method, we can only use this to find the volume of objects that sink in water. Objects that float or dissolve will not displace or move their entire volume.

47. Displacement
Remember that with the water displacement method, we can only use this to find the volume of objects that sink in water. Objects that float or dissolve will not displace or move their entire volume.
Also, remember that when you read a volume measurement on a graduated cylinder, you read it from the side with the meniscus (curve of the water line) at eye level.

48. Density
The SI unit for density is kg/m3, or kilograms per meter cubed. Based on what you know about SI units, what does this unit suggest about the formula or equation used to calculate density?

The SI unit for density is kg/m3, or kilograms per meter cubed. Based on what you know about SI units, what does this unit suggest about the formula or equation used to calculate density?

The same is true for any unit of volume, including g/mL for example, when looking at a liquid volume measurement.

Look at the rocks of pumice and obsidian on page What can you infer about the density of pumice and obsidian compared to that of water?
Pumice’s density is less than the density of water, so pumice floats. Obsidian’s density is greater than the density of water, so obsidian sinks.

59. Summary Matter is anything that has mass and takes up space.
Mass and weight are different properties of matter.
Mass is measured with a balance.
Weight changes with gravity, and it is measured with a scale.
Density of an object is equal to its mass divided by its volume.
