 Scientific Method a systematic process used to gather evidence & solve a problem. Know the Steps! Galileo Problem/Purpose Step #1 Figure out the question you want to answer with this expierement. find the purpose Gathering Information/Research Gathering Information/Research Background info is obtained in class or information may be gathered from observation before beginning Hypotheses #3 answers the question in the problem and tries to explain a relationship between variables Experimentation A- List all supplies neeed in column format B-Procedure- state in specific what you will do indicate what you are using as control Analayze Experimental Results conduct the expierement, collect and document data carefully. Data should be organized in charts and graphs. conclusion Claim- Hypothesis Correct? Evidence- Data supports claim Reasoning- why, how, variables, problems Variable factors that affect the results of an expierent. Only 1 per experiment Dependent Variable the variable in an experiment that changes in response to choices by the experimenter:this variable is plotted on the y-axis of a graph: the factor measured in an experiment (time speed, distance) Independent Variable the variable in an ex. that is manipulated by the experimenter and that causes changes in the dependent variable in the ex. x-axis of graph:single factor that the experiment changes and compares Control standard for comparison in an experiment constant parts of an experiment that remain the same Hypothesis a prediction that can be tested by experimentation Conclusion evalution of hypothesis as a result of data/experimentation Kilo k,1000 Hecto h, 100 Milli m, .001 1/1000 Centi c, .01, 1/100 Weight measures the force of gravity on an object Mass the amount of matter in an object Volume ml or L (liquid) or cm3 (solid) the amount of space an object occupies Meter m, unit used to measure length Liter L, unit used to measure liquid volume Gram g, unit used to measure mass Displacement finding the volume of irregular shaped objects. Grad cylinder & water Density the amount of matter in a given volume. The compactness of matter D=M/V (mass divided by volume) g/cm3 solid or g/mL (liquid). Water ahs a density of 1.0 gram/mL, over 1 sinks, under 1 floats Observation information gathered by senses Inference conclusion drawn from an observation Prediction predict the future based on past experiences Data numerical information(Quantitative) Classify- Group objects based on similar characteristics Theory an explanation based on observations, data and experiements, tested many times. Fact truth based on data Science the process of trying to understand the world, body of knowleddge based on the learning of nature through observations and the scientific method Superstition an irrational belief that an object, an action or a circmstance not logically related to a course of events influences its outcome. made by ignorance of the laws of nature Law proven theory tested over time
