Simulations developed or being developed by author

• Acid-Base Titration
• Chemical Kinetics
• Chemical Equilibrium
• Chromatography (on the way)
• Cyclic Voltammetry (on the way)
• Density
• Flow Injection Analysis
• Heat transfer
• Kinetic vs Thermodynamic control in organic
  reactions (on the way)
• Stoichiometry

Simulations

• Allow the creation of situations for inductive
  thinking processes to take place.
• Promote the process of identifying variables and
  its interrelations, and the observation of their
  effect on the phenomenon or properties under
  study.
• Reinforce the idea of using the experiment to
  acquire new knowledge.
• Can be used to develop experimental design
  skills.

6
With simulations

• Get results that are time/cost effective.
• Avoid real experimental noise.
• Create active learning environments.
