Measurements
The measure of how much mass is contained in a given volume.
Density
The numerical average
mean
The vertical axis of a graph.
up and down (y)
Any area outside the laboratory.
the field
The standard system of measurements that scientist use.
SI (International System of Units)
The amount of space an object or space takes up.
Volume
The number that appears most often in a set of data.
mode
Data that does not fit the trend/data set.
anomalous data
Used to understand how systems work and predict changes in them.
models
How close a measurement is to the true accepted value.
accuracy
The metric system is a measurement system based on this number.
10
The middle number in a set of data.
median
A line graph in which the data points do fall along a straight line.
linear
These alert you to possible sources of accidents in a laboratory
Safety Symbols
How close a measurement is to the true accepted value.
accuracy
The basic SI unit for mass.
kg (kilograms)
The difference between the largest and smallest numbers in a set of data.
range
A line graph in which the data points do NOT fall along a straight line.
non linear
The material or energy that goes into a system.
input
A method to find the volume of an irregular solid (ex. a rock).
displacement
The basic SI unit for length.
meter
The mean in this set of numbers 12, 24, 13, 2, 5
11.2
What shows a relationship between variables.
Trend (linear graph)
The first thing you should do if an accident occurs in the lab.
Alert a teacher
The Volume in a graduated cylinder reads 35. You then put a seashell in it. It now reads 52. The seashell's volume is this.
