Scientific method There are many versions of the scientific method, but basically it’s a way to understand phenomena or find the “truth.” One version includes the following steps:
A few things to consider: · Use the metric system · Write down exactly what you have observed · Your hypothesis should be testable Types of Variables · Independent Variables  are changes by the experimenter. It is changed to observer how it affects the dependent variable. You should only have one independent variable, if you have more you won’t know what caused any changes. · Dependent Variables  are changes that occur due to what the subject does. It results from manipulating the independent variables. · A Controlled Variable  is anything else that could influence the dependent variables. Try to keep these constants for each experiment or trial. · Control Group – is another group that is treated exactly the same except for When conducing an experiment on a group you need to consider group size (sample size) and if they are a representative of the population (random) For Valid results: · Conduct many trials (repeat the experiment) · Have many different subjects Engineering type Projects · Show how something works · Create something new · Solve a problem · Make a new application of an exciting product · Such as constructing machines, structures, circuits, robots, programs Include the following Steps:
Organize and Analyze Data · Chart & graphs · Table · Diagrams · Flowcharts · Do statistics, such as average, median and standard deviation
