STEM EXPOSITION WORKSHOP #3November 25, 2013
Check in with participants
• How's it going?• Any issues we can help with?• How many students are you working with?
COLLECTING DATAScience & Engineering
What Kind of Data Do Scientist and 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• Example of project notebook entry
Notice errors are crossed out,never erased.
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
Simple data table
Independent Variable(units)
Responding Variable(units)
Trial 1 Trial 2 Trial 3 Average
Monitor & Adjust …If When Something Goes Wrong• Most experiments/ designs do go "wrong”.
• Keep a complete record in notebook!
ANALYZING DATAScience & Engineering
Questions to Ask When Looking at Data
Science Investigation• 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?
Invention• Did I collect enough
data?• Is the data accurate?• Did my results match my
design requirements?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 or the
design met the criteria for improvement
• Most controlled investigations will be a XY Scatter
• At least one for all projects!• http://nces.ed.gov/nceskids/help/user_guide/graph/
