STEM EXPOSITION WORKSHOP #2 January 7, 2013
Check in with participants • How's it going? • Any issues we can help with? • How many students are you working with?
Science:Hypothesis & Procedure Quick review about key pieces
Science Hypothesis • If __________, then ____________.
Science: Procedures • Materials list • Step by step so others may duplicate exactly • detailed amounts • how variables will be measured • Repeat trials for multiple conditions!!! • at least 3 • multiple subjects (i.e. plants, people interviewed) • multiple tests (i.e. rolling object down a ramp many times
Engineering: design criteria • Types of design requirement/criteria for general products • Materials list - same as science • Preliminary design & prototypes • Sketches, drawings and models • Use readily available materials: cardboard, paper, foam-core, found objects • Construction kits such as lego, meccano, fishertechnik, electric circuit boards
Collecting Data Science & Engineering
What Kind of Data Do Scientist/Engineers Use? • Determine how researchers in your field of study interpret their data. • Take note of any mathematical formulas or equations that will be needed to describe the results of the experiment • Take note of any information that will be needed to build a prototype.
Take Notes Each Day of the Project • Observations • Potential problems
Take Pictures • Observational data • Reminders of events • Use for display boards • Must be in focus & understandable by anyone!
Numerical Data Science • controlled variables • independent (manipulated) variable • dependent (responding) variable Engineering • design criteria • prototype • rebuild
Monitor & Adjust …If When Something Goes Wrong • Most experiments/ designs do go "wrong”. • Keep a complete record in notebook!
Analyzing Data Science & Engineering
Questions to Ask When Looking at Data • Did I collect enough data? • Is the data accurate? • Did my results match my hypothesis? If, yes... • How does the data supports this conclusion? If no… • How does the data support this conclusion?
Graphs • Used to show how the hypothesis was answered / design met the criteria for improvement • Most controlled investigations will be a XY Scatter • At least one for all projects! • Resource: Create a Graph from Kid Zone (NCES) http://nces.ed.gov/nceskids/createagraph/
Formulating Conclusions • Sample Science Conclusion outline • Follow the Project checklists
Writing the research paper • What should be included – final report check list • Template/chart of research paper format • Abstract – for students moving on to other fairs
Example Projects Invention Investigation For the Birds Keep it Cool • Quiet Down • Junior Light Switcher
