Vocabulary 1
everything that has mass and takes up space
matter
true of false: 1cm3 = 1mL
True!
instrument used to measure mass
balance or scale
units of measure for mass
grams (g)
How do you predict if an object will sink or float?
If the density of the object is greater than the density of the liquid, it will sink. If the density of the object is less than the density of the water, it will float.
the amount of matter in an object
mass
a characteristic of a substance that requires a chemical reaction to observe
chemical property
instruments used to measure the volume of a rectangular prism (block)?
ruler and a calculator
units of measure for length, width, and height
cm (metric)
Sink or Float?
white bead, salt brine
Float!
The amount of space an object takes up
volume
a tool scientists use to represent ideas or provide an explanation, may include diagrams/drawings
model
method used to measure the volume of an irregular object
water displacement with a graduated cylinder
Units of measure for volume of an irregular object like a rock
mL or cm3
Sink or float?
steel bolt, corn syrup
Sink!
can be measured without changing the substance
physical property
the tendency to float
buoyancy
What is the formula for calculating the volume of a rectangular prism (block)?
LxWxH
what does CC mean?
cubic centimeter
sink or float?
nylon spacer, corn syrup
float!
mass of a substance that fills one unit of volume
density
the law that states that an object's volume will be equal to the amount of water it displaces when submerged
Archimedes principle
Formula for density
density = mass divided by volume
d = m/v
Can you measure the volume of a rock by using LxWxH? Explain how.
Water displacement with a graduated cylinder
Sink or float?
