Mass
What is the unit we use for mass?
What is grams.
What is the unit we use for the volume of a REGULAR shaped object?
What is cm3. Centimeters Cubed.
What is the unit is used to label density if the volume was found using length x width x height?
What is g/cm3.
Describe how to use a balance to find the mass of an object.
You can bullet list the process.
Balance to zero first. Then place the object on one side and add up the masses until the arrow lines up with the middle mark.
To find the volume of an IRREGULAR object we use water ________________.
What is displacement.
What is the tool used to measure mass?
What is a (triple beam) balance.
What is the unit we use for the volume of a IRREGULAR shaped object?
What is mL.
What is the unit used to label density if the volume was found using the water displacement method?
What is g/mL.
(Candy lab) If given a REGULAR object, describe in detail how to find the density.
Use a balance to find the mass. Then use a metric ruler to find the volume. Divide mass by volume. Label g/cm3.
Find the volume of the irregular object with the following information: Starting volume=14mL, Ending Volume=38 mL.
What is 24 g/mL
Define Mass.
Amount of matter "stuff" in an object.
What is the formula used to find the volume of a regular shaped object?
What is length x width x height.
LxWxH
This formula is used to find density.
What is mass divided by volume.
(Candy lab) If given an IRREGULAR object, describe in detail how to find the density.
Use a balance to find the mass. Then use a graduated cylinder to find the volume. Divide mass by volume. Label g/mL.
Find the volume of the irregular object with the following information: Starting volume=12 mL, Ending Volume=46 mL.
What is 34 g/mL
Determine the mass of a ball that was equivalent to the following masses: 20g, 20g, 20g, 20g, 10g, 5g, 2g, 1g, 1g.
What is 99g.
Describe the displacement method and how it is used to find the volume of an irregular object.
You can bullet list the process.
Fill a graduated cylinder to a definite mark with water. Record the measurement as the starting volume. Place object into graduated cylinder. Record this volume as the ending volume. Subtract the ending volume minus the starting volume. This is the volume of the object.
Find the density of the object with a mass of 25g and a volume of 10mL.
What is 2.5 g/mL
Can objects with the same volume have different densities? Explain.
YES. Because they may have different masses. This would change the density even though the volume is the same.
Would an object with a density of .75 g/cm3 float or sink?
What is float.
Would an object with a density of 1.35 g/cm3 float or sink?
Find the volume with a length of 12cm, width of 9cm, and height of 7cm.
What is 756cm^3.
Find the density of the object with a volume of 20mL and a mass of 30g.
What is 1.5 g/mL.
Double Jeopardy: Wager your points:
What is the density of water?
What is 1 gram per milliliter.
Find the volume of the irregular object with the following information: Starting volume=12mL, Ending Volume=26 mL.
What is 14 g/mL.
