- 1massThe amount of matter (atoms) in an object.
- 2classificationThe grouping of items based on similarities.
- 3ObservationUsing the five senses to interact with the environment.
- 4percent deviationThe amount of error in a measurement.
- 5cyclic changeEvents occurring in a predictable pattern.
- 6dynamic equilibriumA balance between opposing forces.
- 7volumeThe amount of space an object takes up.
- 8inferenceAn educated guess. An hypothesis.
- 9interfaceA boundary across which energy is exchanged.
- 10rate of changeHow much something changes over time.
- 11densityHow tightly packed the atoms are in an object.
- 12Experimental DesignDescribes the manner in which you test your hypothesis through experimention
- 13Independent Variablethis variable is changed by the researcher and observations are made to see if the change has an impact on the dependent variables.
- 14Dependent VariablesThese variables change as a result of the independent variable. . This is where your DATA comes from.
- 15Controlled VariablesThese are Variables in the experiment that you keep the same
- 16Control Groupthis group does not receive the independent variable. This group is used to compare to as the “normal” or “baseline”.
- 17Experimental Groupsthis group receives the independent variable.
- 18Trialsthe # of times you replicate the experiment.
- 19Data:anything that can be observed/measured in an experiment.
- 20Quantitative Dataanything that can be measured with numbers
- 21Qualitative DataObservations not related to quantities or numbers
- 22What is the formula for finding the the volume of a cube?L x W x H
- 23How do you find the volume of an irregularly shaped object?Put water into a graduated cylinder
Measure the volume of the water
place object in the cylinder, remeasure the water level
subtract the first level from the second level - 24—
