I created this "scientific" animation
in 1996.
|
|
These animations support the teaching of concepts in chemistry in freshman through graduate level courses. The chemistry courses that profit from these sorts of multimedia content include freshman general chemistry, instrumental analysis, environmental chemistry, atmospheric chemistry and air quality. The gold foil experiment movie augments a hybrid on-line freshman chemistry course.
