What is the base unit used for measuring length in the metric system
The meter.
100
Why was the metric system invented when we already had the english system of measurement?
Because the metric system is easier to use
100
How many meters is 2 kilometers?
2 kilometers = 2000meters
100
The amount of matter in an object
Mass
100
How is the volume of a solid regular object calculated?
Length x Width x Height = Volume
200
What is the base unit for measuring mass in the metric system
grams
200
This is a two part question. The metric system uses prefixes. What does the prefix kilo mean? How many meters is 1kilometer?
The prefix Kilo means 1000. 1kilo meter=1000meters.
200
How many centimeters is 2 meters?
2 meters = 200 centimeters
200
The amount of space an object takes up
Volume
200
Explain how we figure out the volume of an irregular object like a rock?
We dropped it in a known volume of water and measured the volume of water that was pushed out of the way. This is called displacement.
300
Wht is the basic unit used for measuring volume in the metric system
liters
300
What metric prefix = 0.01?
Centi
300
How many Liters is 3000mililiters?
3000 milliliters = 3 liters
300
The amount of mass per unit of volume. In other words, the amount of stuff packed into an object.
Density
300
A physics student has a graduated cylinder with 30mL of water in it. She drops a rock in the cylinder and the water rises to 40mL. What is the volume of the rock?
40mL-30ml= 10ml. The rock displaced 10mL of water so it has a volume of 10mL or 10cm^3,
400
What is the tool used for measuring the volume of a liquid
A graduated cylinder
400
What metric prefix = 0.001?
Milli.
400
If 1 mile = 5280 feet, how many feet is 3.5 miles?
3.5miles = 18,480feet
400
The name for the line that a fluid makes when it touches the surface of a container. We observed this when trying to read the volume in the graduated cylinder.
Meniscus
400
Explain why regular coke sinks and diet coke floats.
Regular coke has more stuff in the same amount of space as the diet coke. The more stuff per unit of volume means that regular coke has more density than the diet coke.
500
What units are used when describing the volume of a solid object
What are cm^3
500
Why is the metric system so easy to use?
It is based on 10.
500
If 1 foot = 12 inches, how many feet is 1,152 inches?
1,152inches = 96 feet
500
The term for when a fluid is pushed out of the way when an object is placed it the fluid
Displacement

If you student has a graduated cylinder with 30mL of water in it and drops an object in the water and the volume of water rises to 40mL. The object has a mass of 20grams. what is the density of the rock? Does the object float?
Density=Mass/Volume Volume of the rock = 40mL-30mL Volume= 10cm^3 Mass= 20grams Density=20grams/10cm^3 Density=2grams/cm^s
