Certain concepts in CHEMISTRY is so abstract.Imagination and assumptions by the child is required.Such a concept in CHEMISTRY can be explained very easily with the help computers using ANIMATIONS and MOVIES. There lies the use of computers as TEACHING TOOLS in CHEMISTRY.Hats off to computers!!!!!!!
1.HYBRIDISATION
Hybridisation means mixing of orbitals.By knowing hybridisation we can predict the shape of a molecule. http://www.mhhe.com/physsci/chemistry/essentialchemistry/flash/hybrv18.swf
2.LECHATLIER PRINCIPLE
When a stress or strain is applied to a system in equilibrium , the system will respond in such a way to undo the effect or to nullify the effect.This animation will show the effect of temperature , effect of concentration and effect of pressure on the equilibrium.

3.RUTHERFORD SCATTERING EXPERIMENT
It is one of the milestone in the history of the structure of atom.Rutherford has taken a thin gold foil and bombarded it with alpha rays.He analysed the results scientifically and found out the structure of atom.

4.HYDROGEN BONDING ........MOVIE
Concept is explained well.Self explanatary. http://programs.northlandcollege.edu/biology/Biology1111/animations/hydrogenbonds.html
5.BONDING ANIMATIONS WITH NOTES
http://www2.nl.edu/jste/bonds.htm
6.PERIODIC TABLE AND BONDING
This is an animation relating bonding and periodic table.If the student click both atoms from right side that is non metal side , the result is covalent bond.If the student click one atom from left that is metal side and another atom from right side of the periodic table that is the non metal side, then the result is ionic bond.After playing this animation for twice , students will come to understand well , the relationship between Periodic table and Chemical Bonding.

7.LINE SPECTRA OF HYDROGEN ATOM
Self explanatory for class XI Science students
