- 1what is an observation?a visible or provable fact
- 2What is an inferencean educated guess
- 3what is a question?a statement of what the scientist is trying to solve which specifically questions what is to be measured.
- 4Questions should include both the independent and dependent variables. True or False?True
- 5What is a hypothesis?a statement that expresses the answer or outcome of the experiment.
- 6What format should a hypothesis?If (independent)… then (dependent)… because (scientific properties).
- 7The experiment tests the hypothesis to find the answer to the question. True or False?True
- 8How many independent variables can you test at a time and why?1 because you can tell which independent variable affected the dependent variable.
- 9What is the independent variable?- the manipulated variable
- being changed to measure results
- known before conducting experiment - 10What is the dependent variable?- resulting variable
- what is being measured
- what the scientist is trying to figure out - 11What is the control?- Group/trial that does not have the independent variable applied to the experiment
- Used to compare before applying the independent variable - 12What is the Constant?- factors in an experiment that does not change
- they are consistent through the whole experiment - 13What are the results in an experiment?they are the graphs and charts with data recorded
table ----> graph - 14What is the result anlysis?The written explanation of the results
- 15What does the conclusion present?It presents the findings of the experiment, what the data shows, and states whether the hypothesis was correct or negated.
it also explains to scientific reasoning/principle. - 16What are the 3 factors that show validly in an experiment?1) multiple trials
2) constants
3) reproducibility - 17Experiments that have a small sample size are more valid then those that use a large sample size. true or false?False
- 18What does CER stand for?C-claim
E-evidence
R-reasoning - 19What should be included in the claim of a CER?The answer to the question; does not start with yes or no.
- 20What should be included in the evidence of a CER?the results from the experiment, the observations, the data tables, and graphs
- 21What should be included in the Reasoning of a CER?the why, results, analysis, and part of the conclusion.
- 22Qualitative vs Quantitative.Qualitative: senses
Quantitative: numbers
