Steps of the scientific method
  • State the Problem
  • State the Hypothesis
  • Design an Experiment
  • Record and Analyze the data
  • State a Conclusion

A Valid Experiment MUST have
  • A testable hypothesis
  • A control group
  • Only ONE variable
  • A Large sample size
  • Repeatable 
This is a picture of a Compound Light Microscope which is the one we will be using in class this year

Paper Chromatography

Gel Electrophoresis
A technique used to separate and identify parts of a mixture. Typically color pigments are what is being separated
Uses electrical current to separate DNA and RNA fragments based on  their size

Centrifuge

Used to separate a liquid mixture by density of the substances inside

This is an image of blood before and after it has been run through a centrifuge, the larger more dense cells have gone to the bottom and  the less dense plasma is at the top
