True or (False & Why)
Calculating Density
DUN DUN DUN...
100
the amount of matter in an object
What is mass?
100
You have two beakers. One has 20 ml of water and the other has 20 ml of corn syrup. The two beakers have the same density?
What is false because they have the same VOLUME, not density?
100
A small pen has a mass of 10 grams. It is placed in a graduated cylinder containing 13 ml of water. The water level went up to 15 ml. What is the pens density? (remember units!)
What is 5 g/ml?
200
milliliters (ml) or liters (L) are units for
What is volume?
200
A pencil has a density of 6 g/ml. Miss Burrows' puppy, Jax, is a jerk and chewed it in half. The density of each half of the pencil is 3 g/ml.
What is false because changing the amount of an object doesn't change it's density. It would still be 6 g/ml?
200
The density of an unknown object is 0.80 g/ml. Is it more or less dense than water?
What is less dense?
300
the formula for this is mass divided by volume
What is density?
300
A rock has a mass of 30 grams and a volume of 60 ml. It will sink in water.
What is false because density = mass divided by volume, or 30 divided by 60, which is 0.5 and that is less than the density of water (1) so it will float?
300
Calculate the density of the apple using the information given: Mass: 6.0 grams Volume: 12.0 ml
What is 0.5 g/ml?
400
graduated cylinder, ruler, and/or a drippy cup are instruments used to measure
What is volume?
400
A block of aluminum has a length of 2cm, a width of 2cm, and a height of 3cm. It has a mass of 24g. There is not enough information to determine the density.
What is false because you can figure out the volume by multiplying length x width x height and then dividing it by the mass to get a density of 2 g/cm3
400
Will the apple that was 6 grams and 12 ml float or sink in water?
What is float?
500
1 cubic centimeter (cm3) is equal to 1
What is milliliter (ml)?

Miss Burrows hands you an object her doggy Madison Boots found on the ground. She asks you to determine if the object is more or less dense than water. You place the slobbery object in water and it sinks. The object is more dense than water
What is true?
500
***DAILY DOUBLE*** Using density AND correct vocabulary, explain why warm air rises and cold air sinks.
When air heats up, it EXPANDS and gets LESS dense causing it to rise. When air cools down, it CONTRACTS and gets MORE dense, causing it to sink.

Mrs. Coleman gave Miss Burrows a bracelet that she said was very expensive because it was made of real gold. Miss Burrows knows Mrs. Coleman is a filthy liar, so she wants to check if the bracelet really is pure gold. Miss Burrows has a chunk of pure gold at home (because who doesn't?) How could Miss Burrows use the bracelet Mrs. Coleman gave her, plus the chunk of pure gold she has, to figure out if Mrs. Coleman was honest for once?
Miss Burrows will orally give the answer
