experiment organized procedure to study something under controlled conditions
observations using your senses to obtain(get)information
hypothesis a testable idea that leads to a scientific investigation
data information gathered by observation or experimentation that can be used in calculating or reasoning (data is organized using charts and graphs)
independent variable (test) test-the variable that is deliberately manipulated in an investigation (what you change or are testing)
dependent variable (outcome) outcome-changed as a result of the manipulation of the independent variable (the result or outcome)
model representation of an object or a process that allows scientist to study something in greater details
inference Using your observations to make a guess about an object or an outcome
Steps of the Scientific Method to solve a scientific problem Ask a Question, Form a Hypothesis (possible answers),Test the hypothesis using an Experiment,Collect and analyze Data using charts and graphs & Conclusion-was your hypothesis supported or not supported
Qualitative Observation When studying something: describe only facts that you can see, touch, taste, smell and hear (ABC's)
Quantitative Observation When studying something describe only facts that you can measure (1,2,3-Numbers)
Prediction A statement or claim that a particular event will occur in the future.
Control group the group in an experiment that does not change
repetition when you do something over and over again
replication when you repeat an investigation that someone else has done ad get the same results
trials in science, it is how many times you repeated the same experiment, the average number of times is three
valid in science, after completing an investigation, you must determine if you can count your results or if you need to retest. Valid means that it counts.
pseudoscience "false" science but often resembles science but does not have evidence
