Question or Term | Answer or Definition |
Hypothesis | Hypothesis is testable AND eplains the expected relationship between the independent and dependent variables. Often written in the "if...then..." format |
Independent Variable | manipulated part of experiment, the ONE "thing" you are testing, x-axis, "If..." part of hypothesis MIX- manipulated, independent, x-axis |
Dependent Variable | responding part of experiment, the outcome, the measurable data, might have more than one, y-axis, "Then..." part of hypothesis DRY- dependent, responding, y-axis |
Controlled Variables | conditions kept the same between control and experimental group |
Control Group | "standard", normal conditions-> used as baseline/comparison Independent variable NOT applied |
Experimental Group | test group, Independent variable applied |
Qualitative Observations | using specific and detailed adjective to describe |
Quantitative Observations | using a number (measurement or count) |
Inference | educated guess based on observations |
What is the purpose of experimentation? Why is no experiment a failure? | The scientific method is a general set of guidelines that uses critical thinking to solve problems. TO LEARN SOMETHING! TO LEARN ABOUT SCIENCE! |
Know the difference between Scientific Theory and Scientific Law | Scientific Law describes WHAT happens in nature Scientific Theory describes the process by which it happens (HOW) |
Precision | how close two measurements are to each other |
Accuracy | how lose measurements are to the target value, based on how well the equipment is calibrated, and IS IT CORRECT? |
Length SI unit, instrument used | Meters (M); Meter stick |
Area | Meters Squared (M2); Meter stick |
Volume (Solid) | Meters Cubed (M3); Meter stick |
Volume (Liquid) | Cubic Centimeters (cm3) Liters (L) Milliliters (mL); Graduated Cylinder |
Mass | Kilograms (kg); balance |
Density | g/mL g/cm3; g/ml-> triple beam balance g/cm3-> graduated cylinder/meter stick |
Time | Seconds (s); stopwatch |
Temperature | Kelvin (K); thermometer |
Describe what makes a precise measurement ad accurate measurement? | |
What do you need besides a number when you are measuring? | |
In a given measurement, which digit is estimated? | |
Know what a graph should include and be able to reference the TALKS rubric. | |
How do graphs relate to experiments- in what way do they relate to the IDV and DV? | |
What is the order of scientific thingies from least to most reliable? | Least reliable-> Hypothesis (formal inference made prior to experimentation) Moderate reliability-> Conclusion (results of ONE experiment) Most reliable-> Scientific Theory, Scientific Law (results of MANY repeated experiments, well established) |
