copy deck
- The equal size values represented by the equal spaces marked along the axis of a graph, or the spaces between units of a measuring device.
- intervals
- The last section of a report of an experiment; it states the purpose, major finds, hypothesis, a comparison of the findings of this experiment with other experiments & recommendations for further study.
- conclusion
- A chart to organize and display the data collected in an experiment
- data table
- A decimal system of weights and measurements based on units such as grams,meters, and liters
- Metric Measurement (SI)
- A list of everything you need in an experiment. (Always identified on one's science board prior to explaining the procedure. (experiment)
- Materials
- A logical way to pose and answer questions or develop and solve problems in science.
- Scientific Process
- A measure of how a set of measurements or count data is spread out. It is calculated by subtracting the minimum value from the maximum value.
- range
- A paragraph at the beginning of a report of an experiment that states why the experiment was done(reason); what was expected to be learned(purpose)by doing it, and was the hypothesis proven or disproved.
- introduction of conclusion
- A pictorial display of a set of data.
- graph
- A pictorial display of data that can be drawn when the data for both variables are continuous data.
- line graph
- A prediction of the relationship of an independent and dependent variable to be tested in an experiment.
- hypothesis
- A section of the report of an experiment that includes the data tables, graphs, and sentences that summarize any trends found in the data.
- results
- A sequence of precisely stated steps that describe how an experiment was done, including the materials and equipment used.
- procedure
- A series of equal intervals and values placed on each axis of a graph.
- scale
- A statement describing an experiment or data table. These statements are often written in the form, "The Effect Of Changes in the Independent Variable on the Dependent Variable"
- title
- A test of a hypothesis. It determines if purposely changing the independent variable does indeed change the dependent variable as predicted.
- experiment
- Data that are descriptions of qualities such as shape, color, and gender.
- observations
-
If ____________ (IDV)THEN ___________
________(DV)_______________BECAUSE: - Hypothesis format
- Information or values determined by calculations using collected data; examples are means, medians, modes, and ranges.
- derived quantity
- The bits of information (measurements, observations, or counts) gathered in an experiment.
- data
- The central value in a set of data ranked from highest to lowest. Half the data are above it and half are below.
- median
- The factor or variable that may change as a result of changes purposely made in the independent variable. ( Must be measureable)
- dependent variable (responding variable)
- The general direction or pattern of the data; it is usually illustrated on a graph as a line of best fit.
- trend
- The horizontal or vertical line found at the bottom and left side of a graph
- axis
- The line drawn on the left side of a graph on which the scale for the dependent variable is placed.
- vertical (Y) axis
- The most central or typical value in a set of quantitative data.
- average (mean)
- The most typical or central value of a set of qualitative data.It is the value that occurs most often in the set.
- mode
- The number of times that a level of the independent variable is tested in an experiment or the number of objects or organisms tested at each level of the independent variable.
- repeated trials (5)
- The part of an experiment that serves as a standard of comparison.
- control
- The variable that is changed on purpose by the experimenter.
- independent variable (manipulated variable)
- This is the line along the bottom of a graph on which the scale for the independent variable is placed.
- horizontal (x) axis
- Those factors in an experiment that are kept the same and not allowed to change or vary.
- constants
- a control that receives none of the independent variable, for example ( a set of plants that receives no fertilizer.
- no treatment control
