Sol PS1 Lab Equipment Triple beam balance Thermometer

Sol PS-1 Lab Equipment • Triple beam balance • Thermometer • Metric ruler • measures mass, metric unit is the gram • Measures temperature celsius/kelvin • Measures length in centimeters or millimeters

Lab Equipment • Graduated cylinder • Spring scale • Measures liquid volume, metric unit is milliliter or liter, read bottom of meniscus • Measures force in Newtons

Graphs • Bar graph • Line graph • Demonstrates change that is not continuous. • Indicates trends when the data cover a long period of time. • Demonstrates continuous change. • Independent variable is on the X axis • Set of data called a data pair.

Graphs • Circular graph • Shows how each group of data relates to all of the data. • Each part represents a category of the data.

Scientific Terms • Density • Weight • Mass • The amount of matter per given volume. • D=Mass/Volume • A measure of the gravitational force on an object, varies with location • The amount of matter in an object

Scientific Terms • Volume • The amount of space that matter occupies • Liquid volume is measured with a graduated cylinder (m. L or L) • The volume of a solid is measured with a metric ruler (Lx. Wx. H) which is cubic centimeters

Scientific Terms Independent variable • Also called the manipulative variable • This is the variable that causes the change, the one you can control • Located on the X axis Dependent variable • Also called the responding variable

Scientific Terms • Dependent variable • Is the result of the manipulated variable • Located on the Y axis • Constant variable • Factors or variables that stay the same • Control • The group that does not get any special treatment

Scientific Terms • Scattergrams or Scatter Plots • A graph that shows the relationship between two sets of data. • Two sets of data are graphed as ordered pairs on a coordinate plane. • Often shows a pattern, trend, or relationship between the variables

Scientific Terms • Histograms • Type of bar graph used to display numerical data that have been organized into equal intervals.
