MEASUREMENT: How do we commonly measure mass? (think about the triple beam balance) |
in grams
|
|
|
MEASUREMENT: What is volume?
|
the amount of space something takes up
|
|
|
MEASUREMENT: How can you find the volume of a regular shaped object?
|
measure its length, width, and height in centimeters then multiply the values to get the volume in centimeters cubed
|
|
|
MEASUREMENT: How can you find the volume of any object?
|
use the displacement method-fill a graduated cylinder with water and place the object in it- measure how much the water level rose and that will give you the volume
|
|
|
MEASUREMENT: 1 cubic centimeter is equal to __________
|
1 milliliter
|
|
|
MEASUREMENT: What is density?
|
the ratio of an objects mass to its volume
|
|
|
MEASUREMENT: How is density measured?
|
using grams and cubic centimeters (or milliliters) -the final end unit would be grams per cubic centimeter
|
|
|
HYPOTHESES: What is the format of a hypothesis?
|
if/then/because statement
|
|
|
VARIABLES: What is a variable?
|
any factors that could change in a scientific investigation
|
|
|
VARIABLES: What is an independent variable? |
the factor being tested or that could be changed so you can identify it's effects--(bonus) stated in hypothesis after "if"--plotted on the x axis
|
|
|
VARIABLES: What is a dependent variable? |
the factor measure to gather results/ gather a conclusion--(bonus) in hypothesis after "then"-- plotted on the y axis
|
|
|
OPERATIONAL DEFINITION: What is an operational definition?
|
a description of the one particular way in which you would measure the dependent variable
|
|
|
OPERATIONAL DEFINITION: What is a qualitative observation? |
qualitative observations include a description of sights, sounds, smells, and textures (found using your senses) / non specific / answers a yes or no question |
|
|
OPERATIONAL DEFINITION: What is a quantitative observation? |
quantitative observations use specific units of measurement / uses numbers
|
|
|
PREDICTIONS: What is an interpolation?
|
a prediction made between known data points
|
|
|
PREDICTIONS: What is an extrapolation?
|
a prediction made beyond known data points
|
