Laboratory Techniques

Laboratory techniques are always useful when planning your science fair project. These can help you organize and save time!

Gel Electrophoresis
This technique is useful for forensics, molecular biology, genetics, microbiology or biochemistry experiments.
Spectrophotometry
This technique is useful for physics, chemistry, biochemistry, and molecular biology experiments.
Serial Dilution
This technique is useful for experimental sciences include biochemistry, pharmacology, and physics as well as in homeopathy.
pH Indicator Paper
This technique is useful for medicine, biology, chemistry, food science, environmental science, oceanography and many other applications.
Weighing
This technique shows you how to use a balance and make precise and accurate weighing measurements.

In order to correctly write down your results while doing these procedures, we have included some guides on lab note taking to aid you in this process.

Engineering and Math Lab Note-Taking
A quick guide which details effective lab note-taking for engineering and math.
General Science Lab Note Taking
An extensive and detailed guide for all sciences
Behavioral Lab Note Taking
An easy guide for behavioral sciences; includes a detailed example.
Error Analysis
One frequent problem with science fair projects is the lack of error analysis. This will help you understand common sources of experimental error.

Whenever using these techniques or performing experiments remember to always use proper safety procedures. Go to Safety for proper safety procedures.
