Steps of the scientific method

  • State the Problem
  • State the Hypothesis
  • Design an Experiment

Paper Chromatography

Gel Electrophoresis

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

Picture

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
