Learning modules 

1) Are We Overusing Plastic?

Plastik

Plastics have invaded our lives to such an extent that it is almost impossible to think of life without them. Since plastics do not decompose as easily as other materials, their excessive use has created a problem of disposal of discarded products like plastics bags and bottles. As a result, plastics are slowly becoming a potential danger to the environment. There is thus the problem of plastic waste disposal or re-use.

2) How Happy are You and Your Family with the Electricity Bill?

Elekter

This module leads to a decision making activity, designed to consolidate learning about consuming energy, and energy saving, taking examples from everyday life and to introduce the concept of power. It involves the reading of an electricity bill and checking that the calculation of the bill is correct. It introduces students to the (kilo)watt as a unit of power and the kilowatt hour as the unit used in the home for energy consumption.

3) How Best to Maintain a Metal Bridge?

sild

 

This set of activities allows students to consider factors which can be involved in determining the best way to protect a metal (iron) bridge. In tackling this issue, students are guided to realise that they need to be aware of the factors that cause iron to rust and also that sacrificial metals can protect iron. The sacrificial metals can be put in a series such that the metals higher in the series protect those below from corrosion (rusting). The decision making on which method to use to protect the bridge involves the consideration of a range of social factors from the need to provide employment to people, to ensuring maximum safety, to cost and also the bridge being aesthetically suitable for the surroundings.

4) Should Vegetable Oils be used as a Fuel?

lill

This module explores the ethical dilemma in using edible substances as fuels. In this aspect the problem did not arise because vegetable oils were too viscous to be used in standard engines. But by a process of exchanging the ester components the oils are mad in a substance resembling diesel and have less polluting properties. This module explores the making of biodiesel and its suitability as a fuel before trying to decide whether it is appropriate in this day and age of high costs of diesel to use vegetable oils as a source of fuels.
