    • Question
    • Answer
    • Side 3
    • A Good Experiment should have?
    • One Variable; More than one setup; A control group
    • What is an Control group?
    • A control Group is use for comparison with the experimental group. It must have consisent factors - nothing is changed with this group
    • What is an Experimental Group?
    • An experimental group is the group that has the variable that will be compared with the control Group.
    • What is a variable?
    • Is the differnt factor between a control group and experimental group. Note: everything else should be the same.
    • What is a consistent factor?
    • All remaning factors must be consistent and the same between both the experimental and control group.
    • What is a Hypothesis?
    • Possible answer or explanation that can be tested.
    • What is a conclusion?
    • When you consult the results of the experiment and determine if the results support the hypothesis; involves thinking, Uses statement "because" Possible explanation
    • What is the sciencetific Inquiry process?
    • OHEAT: Observation, Hypothesis, Experiment, Analyze Data, conclusion and theory.
    • What is an observation?
    • uses your senses, uses tool or number, calculations and measurements
    • Do observations or conclusions appear in the results section?
    • observations
    • Why should there be only one variable?
    • It would make it simpler to figure out what caused the change. It would be able to compare the two groups more accurately.
    • Why should an experiment be done twice? Give Example?
    • Because the setup could have a deformation and cause an experimentant error. This could affect the outcome of the experiment. Give example?
    • How can results be described in the results section?
    • Date; Observation; Drawings
    • What information should be reported in the discussion of your results?
    • Question; Restae your hypothesis; Was hypothesis supported by results; Any source of error; Conclusion - one sentence
    • What is a dependent variable?
    • The dependent variable will vary depending on what happens to the independent variable. Graphed on Y-axis
    • What is an independent variable?
    • The independent variable does not change. Changes to the independent variable can change the dependent variable. Graphed on X-axis.
    • Infer or Inferencing
    • explain or interpretting things you observe
    • Predicting or Prediction
    • making a forecast of what will happen in the future
    • Quantitative Data
    • Actual numerical data (measurements, etc.)
    • Qualitative Data
    • What does it look like, often from senses
    • When should you start preparing for a lab?
    • 1 day before (at least)
    • If you are unclear about something in science class/lab what should you do?
    • Ask the teacher
    • Measurements are made in science using what system?
    • Metric (SI) system
    • What is a theory?
    • General explanation of a set of observations about the natural world; supported by lots of data collected from many different experiments and observations
    • What is a manipulated variable?
    • Same as independent variable: variable changed during experiment
    • What is a responding variable?
    • Same as dependent variable: the variable you measure or observe during the experiment
    • What type of metric unit would be used for mass?
    • Grams
    • What type of metric unit would be used for volume?
    • Liters or cubic centimeters
    • What type of metric unit would be used for distance?
    • Meters
    • What are models?
    • Representation of objects
