Used to measure weight
Scale
Water's density is __
1
(one)
Will this object float in water?
Density is 6
NO
(It will sink)
What tool do we use to find an object's mass?
Triple Beam Balance
Mass affected by gravity
Weight
Why do we use the displacement method?
Irregular shaped-object's volume
or
If it is NOT a box or cube shape
Volume of a cube:
L x W x H
length x width x height
Which items will sink in water?
Densities:
A = .0008
B = 1.0009
C = 34.00
D = 000.09
E = 10
B C E
What are the three UNITS of measurement in the METRIC system?
Meters
Liters
and Grams, oh my!
Define MASS:
Amount of MATTER (stuff) in an object
Why do we "cube" our answer for volume?
Because it is using three dimensions
or
There is a Length, Width and Height (3)
Buoyancy is determined by the _______________ of an object compared to the liquid you are placing it in.
Density
Find the Volume of a 3 foot box:
27 CUBIC FEET
OR
27 ft 3
The planet Mars has the weakest gravity and the planet Jupiter has the greatest gravity in our solar system.
Where would your weight be the highest?
A) Mars
B) Jupiter
C) Earth
B) Jupiter
Greater gravity pulls your mass the strongest making you seem heavier.
DOUBLE JEOPARDY!!
HOW do we label density?
Grams per centimeter g/cm
or
Grams per milliliter g/ml
A bunch of objects have densities that range from .006 to 8.29.
What do we know about these objects' buoyancies in water?
A) they will all sink
B) some will sink, some will float
C) They will all float
B) some will sink, some will float
(Because the values above one will sink and the values below one will float BECAUSE water's density is 1)
What is this showing?
Displacement Method
If the water level is at 50 ml in my cup and a candy falls in and the level rises to 76ml, what does this tell us about the candy?
The candy's VOLUME IS 26 ml (milliliters)
Name this tool/instrument:
Triple Beam Balance
The amount of space an item takes up is its _____________.
Volume
What is this tool used to find?
Volume of liquids
DOUBLE JEOPARDY!!
What is the temperature in Celsius*?
42
(degrees celsius)
Read the TBB:
190.3 (or 190.4) GRAMS
What measurement could be labeled as CM 3 (centimeters cubed)?
Volume of a cube/box
For one substance to FLOAT in another, its density must be ______________.
LOWER/Less than that substance's density
or
Less than 1 if water
