This is a type of calculator that lets your quickly visualize math. You type an equation and this tool draws it for you without complicated commands.
Hypothesis
This is a prediction of the outcome of scientific processes based on analysis.
Independent variable
This is the manipulated variable in an experiment or study whose presence or degree determines the change in the dependent variable. When graphed this is graphed usually on the horizontal axis.
Inference
This is the process of making a prediction based on the results of prior observations of similar events.
Inquiry
This is the act of trying to find the answer to an unknown question by the use of experimentation and research.
Interpolation
This is the process of predicting the value of an unknown data point within the range of a set of known data points.
Investigation
This is the method of researching or studying a topic. Examination, inquiry...
Lab safety
This is the act of being responsible while working on a scientific investigation; following directions, wearing apron and goggles, knowing the location of emergency equipment, etc.
Life cycle
This is the time of development of one generation.
Line graph
A graph that is represented by points connected by segments.
Logic
This is the science of correct reasoning. The basic components are statements that can be true or false, but never both.
Manipulated variable
This is the one factor that is changed or tested by the person doing the investigation.
Mean
This is a measure of central tendency; in a set of data is what people refer to as the average.
Measurement
This is collection of quantitative data made by comparing a quantity with a standard unit. In science, the units are metric.
Measurement error
The difference between the accepted value and the experimental value.
Median
This is a measure of central tendency; it is the number in the middle of a data set.
Metric system
This is the decimal system of weights and measures based on the meter as a unit length and the kilogram as a unit mass.
Microscope
Equipment used to magnify and observe small objects.
Mode
This is the value that occurs the most frequently in a data set.
Model
A small object, usually built to scale, that represents in detail another, often larger object.
Observation
This is a process of watching an experiment and noting what occurs.
Peer review
This is the evaluation of scientific research, creative work, or performance by other people in the same field in order to maintain or enhance the quality of the work or performance in that field
