1. Introduction The progress in science and technology during the last few decades has conclusively changed our conception of the significance of various scientific disciplines. The increasing chemicalization of the knowledge is related to the fact that, the progress of learning does not only widens the scope of our knowledge but deepens it and make it more exact. Science education is the field concerned with sharing scientific knowledge, and methods with people not considered part of scientific community...

1. Introduction Numerous chemical insecticides have been used to control some insects. While chemical insecticides have knock down effect, they are too expensive harmfull to both humans and the environment. In addition, target insect pests develop biological resistance rapidly especially at higher rates of application. Thus, the increase in pesticidal application to control this pest has urged to researcher to search for biological control alternatives that would be a good component of Integrated Pest Management...

1. Introduction Algae are plant-like, unicellular or multicellular aquatic organisms. Bioremediation performed by algae is termed phycoremediation. The use of algae to treat wastewater has been in vogue for more than 50 years with one of the first descriptions of this application being reported by Oswald in 1957. Phycoremediation is used to describe remediation of contaminants in a water body using algae (micro and macro algae). It is a branch of bioremediation that makes use of algae. It is a bio-restoration technology involving the use of algae and it is relatively new in Africa...
