Fate of the World

The year is 2020. Climate change has been ignored. Cities are underwater. People are starving. Nations brace for war. Species are dying. And you’ve got to solve the crisis. The fate of the world is in your hands

This course covers the types of knowledge and skills required to teach mathematics successfully. It will expose students to the work of teaching mathematics and develop their pedagogical content knowledge of teaching and learning different mathematics concepts. Its main aim is to advance students’ understanding of teacher knowledge bases and mathematical knowledge for teaching. Students will be exposed to different types of teaching strategies and problem solving in mathematics. The course will further discuss development of aims, learning outcomes, schemes of work and lesson plans for mathematics. The course will link theory to practice by providing opportunities for students to practice preparation and teaching of some school mathematics.


This course is aimed at equipping  students with relevant knowledge and skills in handling food to maintain its quality for the safety of consumers.


Many chemical reactions do not go to completion but instead attain a state of chemical equilibrium.   Chemical equilibrium: A state in which the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant. Equilibrium is a dynamic process – the conversions of reactants to products and
products to reactants are still going on, although there is no net change in the number of
reactant and product molecules



Gases are everywhere. People have been observing their behaviour, and that of matter in other states throughout history,-three of the four elements of the ancients were air (gas), water (liquid) and earth (solid). However, many questions remain. In this chapter and its companion, we examine these states and their interrelations. Here we highlight the gaseous state, the one we understand best. Although the chemical behaviour of a gas depends on its composition, all gases have remarkably similar physical behaviour, which is the focus of this unit. For instance, although the particular gases differ, the same physical behaviours are at work in the operation of a car and in the baking of bread, in the thrust of a rocket engine and in the explosion of kernel of popcorn, in the process of breathing and in the creation of thunder.


The course gives students an overview of the various issues and concepts used in the study of language.
