  1. STEM EXPOSITION WORKSHOP #2 January 7, 2013

  2. Check in with participants • How's it going? • Any issues we can help with? • How many students are you working with?

  3. Science:Hypothesis & Procedure Quick review about key pieces

  4. Science Hypothesis • If __________, then ____________.

  5. 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

  6. Engineering: Criteria & Prototype Design

  7. 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

  8. Collecting Data Science & Engineering

  9. 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.

  10. Simple data table

  11. Take Notes Each Day of the Project • Observations • Potential problems

  12. Take Pictures • Observational data • Reminders of events • Use for display boards • Must be in focus & understandable by anyone!

  13. Numerical Data Science • controlled variables • independent (manipulated) variable • dependent (responding) variable Engineering • design criteria • prototype • rebuild

  14. Monitor & Adjust …If When Something Goes Wrong • Most experiments/ designs do go "wrong”. • Keep a complete record in notebook!

  15. Analyzing Data Science & Engineering

  16. 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?

  17. 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/

  18. Formulating Conclusions • Sample Science Conclusion outline • Follow the Project checklists

  19. 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

  20. Example Projects Invention Investigation For the Birds Keep it Cool • Quiet Down • Junior Light Switcher

  21. Aiming for the local State fairs CSRSEF – Bellevue - HS only- March 9, 2013 • Jan 20-26: Complete the form wizard • Registration deadline - February 27 WSSEF – Bremerton - all ages- April 5&6, 2013 • no details on website at this time

  22. Registering for the Exposition • New Registration Form • Jan 21-25

  23. STEM Resources up on District Website for public viewing • Edmonds School District Homepage www.edmonds.wednet.edu • Departments STEM • STEM Exposition contains all the document resources and links we have shared.
