Chapter 7
The Technical Laboratory

2. Introduction
This chapter is intended to make you aware of how to work safely and effectively in the laboratory and report your findings clearly and efficiently.

3. Laboratory Technician
Be patient and methodical
Pay attention to detail
Plan and prepare
Be accurate
Communicate clearly and effectively
Corning example – Report writing and presentations important.
Formal report.

4. Scientific Method – Problem Solving
State the problem
Form the hypothesis
Experiment and observe
Interpret the data
Arrive at the conclusion

5. Performing the Experiment
Equipment specified
Data sheets
Group work
Conclusions drawn

6. Reducing Error in the Laboratory

7. Data Collection and Calculating Results
Scale Resolution – no better than one-half of the smallest division

8. Data Collection and Calculating Results
Digital Meter Accuracy – specified as +/- (percent of reading + number of units in the least significant digit)
Example:
Stated accuracy: +/- ( )
Scale reading of 1000 for Figure 7.10
1000* = +/- 7 volts
