looking for someone who can develop case studies to help in teaching Chemistry, Biology, Computer science and/ or Physics concepts. The case studies must present/ explore at least two different fields of studies e.g. color pigments from plants and pH regulation; physics (optics) and human anatomy (biology of eye), Fibonacci numbers in nature etc. In addition, the case studies need to be investigational in nature and not a simple experiment to be followed or story to be read. Examples available on request.
