stem exposition workshop #3

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/
