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 Sol PS-1

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

3. 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.

4. Graphs Circular graphShows how each group of data relates to all of the data. Each part represents a category of the data.

5. 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

6. Scientific Terms VolumeThe amount of space that matter occupies Liquid volume is measured with a graduated cylinder (mL or L) The volume of a solid is measured with a metric ruler (LxWxH) which is cubic centimeters

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

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

9. 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

10. Scientific Terms HistogramsType of bar graph used to display numerical data that have been organized into equal intervals.
