Unit 1: The Scientific Method
Scientific progress is made by asking meaningful questions and conducting careful investigations. Plan and conduct a scientific investigation to test a hypothesis. Evaluate the accuracy and reproducibility of data. Distinguish between variable and controlled parameters in a test. Recognize the slope of the linear graph as the constant in the relationship y=kx and apply this principle in interpreting graphs constructed from data. Construct appropriate graphs from data and develop quantitative statements about the relationships between variables. Apply simple mathematical relationships to determine a missing quantity in a mathematical expression, given the two remaining terms (i.e. Speed = Distance/Time).** Distinguish between linear and nonlinear relationships on a graph of data.
