2What is used to make an observation?
The 5 Senses
3Inference
Hypothis or educated guess
42 Examples of classification system
Types of rocks and types of stars
5A tool used for mass
Scale, triple beam balance
6If an object is heated, what happens to the mass?
Nothing! The gravitational pull on an object could change the weight, but not the mass
7A tool used to measure volume
A ruler
9Tools used to measure the volume of an irregular object
Graduated cylinder, water
10When an object is heated, it (expands/compacts)
Expands
11When an object is heated, it becomes (more/less) dense
Less

More
14What happens to the density of an object when it is split into smaller pieces?

16Mass
The amount of matter an object or substance contains
17Volume
The length, width, and height that determines how much space the oject takes up
18Density
How tightly packed an object's atoms are
19Displacement
When matter occupies the spot of another object
20Percent Error
How close to correct your answer is
21How do you find percent error?
Percent Error = (average of measured value) - (accepted value)/(accepted value) x 100
22Inverse Relationship
When the x-axis and the y-axis both decrease
23Cyclic Change
A repeating pattern occurs over and over again
24Rate of Change
ROC = Change in value/time
25Direct Relationship
When the x-axis and the y-axis both increase
