# 2.2 Primary, secondary and tertiary industries

 Page 2 / 2

When you want to sell a product that you have made, you must sell it for more money than it has cost you to make it. You must therefore work out what it will cost to make before you make a product. These costs are the PRODUCTION COSTS . You must also work out the production costs for services which you wish to render.

Hint to the educator : Let learners do the next assignment in groups.

Let each group choose a different item.

1. The problem

You are a keen soccer/rugby/hockey player and you practice with the boys at the school for an hour every Monday and Wednesday. Because of the punishing programme that the coach subjects the players to, everyone is exhausted after the session and everyone stands in a queue to get water from one of the two taps alongside the rugby field. Immediately you recognise the opportunity of selling iced lollies to the players at the end of the session - with the coach’s approval, of course.

You test their opinions and find out that the majority of the approximately 30 players will support you at least once a week. Now you have got to get to work. Luckily some of your friends have offered their help.

## Assignment 5

Visit at least five different wholesalers/retailers/supermarkets/shops that sell lollies and then fill in the following table:

 Name of business Number of units per pack Price Price per unit

(NB Each member of the group has to visit a shop)

## Assignment 6

At which shop are you going to buy your goods – and why?

## Assignment 7

How much must you charge for each item if you want to make 50% profit on each item that you sell?

How much profit are you making per item?.

## Assignment 8

If you decide to buy 40 items each week, how much will you pay?

How many units will you be buying?

## Assignment 9

1. What is the total profit if you sell 40 items each week?
1. How are the profits going to be divided between you and your friends?
1. How are you going to store the items if you do not sell everything each week?
1. What money will you use to buy the first week’s supply?
1. What money will you use to buy new supplies each week?
1. Challenge

What about your group attempting to make this scheme a reality? Let your dreams take wing and fly!

## Assessment

 Learning Outcomes(LOs) LO 1 THE ECONOMIC CYCLEThe learner is able to demonstrate knowledge and understanding of the economic cycle within the context of the economic problem. Assessment Standards(ASs) We know this when the learner : 1.1 describes the roles of households, businesses and government in the economic cycle; 1.2 compares the rights and responsibilities of each of the participants in the production and consumption of resources and services. LO 2 SUSTAINABLE GROWTH AND DEVELOPMENTThe learner will be able to demonstrate an understanding of sustainable growth, reconstruction and development, and to reflect on related processes. We know this when the learner : 2.1 researches and analyses standards of living and patterns of consumption in modern societies where people specialise and trade to satisfy needs and wants.

## Memorandum

Assignment 1

• Learners can form groups and study pages 9 and 10. Then they can answer Assignment 8 as a group. It is also possible for them to answer it individually if needs be.

Assignment 2

• Learners can discuss and study pages 11 and 12 individually or in groups, and then do the assignment. Thereafter the assignment can be checked by the whole class as a group.

Assignment 3

• Once learners understand the three types of industries this assignment can be done individually, by the whole class as a group or by smaller groups.

Assignment 4

• This assignment is optional.

Assignment 5

• This assignment is optional.

Assignment 6 – 9

• The teacher divides the class into groups hereafter Assignments 13 to 17 are done. The teacher guides the learners and explains concepts as necessary.

please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
