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. ScienceHypothesis 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 Independent Variable (units) Responding Variable (units) Trial 1Trial 2Trial 3Average

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 Quiet Down Junior Light Switcher Investigation For the Birds Keep it Cool
