What tool do we use to measure
mass?
Triple Beam Balance or electric scale
Convert 0.576cm to mm.
5.76mm
What tool do we use to measure
length?
Metric ruler
What units do we usually use to
measure a regular solid object’s volume?
cm3
What is the basic unit for length?
meters
What has mass and takes up
space?
matter
What do we call the curvature of the water that we measure when
finding volume of a liquid?
meniscus
What is the equation for
density?
Density = mass/volume
What is the formula to find volume of an irregular object?
Final-initial= displacement
If an object has a density of 2 g/cm3 and a volume
of 5 cm3
what is the mass of the object?
10 g
Describe what happens in a
chemical change?
Properties form new and different properties
What tool do we use to measure
regular solid volume?
Metric ruler
Give me an example of a
physical property.
(answers may differ….see frame for details)
Ice melting is an example of what kind of change?
physical
When ice melts what is the
property that is being changed?
State
What is malleability?
Physical property that means the matter can be
pounded into sheets
What does ductility mean?
Pulled into wire
Convert 4.56 kg into grams
4,560 g
1 mL = _____ cm3
1
What tool do we use to measure irregular solid
volume?
Graduated cylinder
If you cut a lemon in half what happens to its density? Explain
Answers may vary… see density notes
What is the difference
between weight and mass?
See Venn Diagram or metric frame to compare and contrast
What units (basic unit) do we use to
measure mass?
grams
What is temperature?
How fast/slow molecules are moving
How do you find the volume of a regular
solid object?
LxWxH
What units do we measure a hot
night?
Degrees Celcius
What is the difference between a property
and change?
Properties describe and changes alter.
What is the difference between a physical
and chemical change?
Physical changes keep the same composition where a chemical change turns it into a new
substance with different properties
