Eco Assignment 7 – Grade 05

Grade 5: Eco-assignments

In South Africa we have many natural resources allowing us to grow a variety of economic activities in both the mining and manufacturing sectors. List 10 economic activities from the mining and manufacturing sectors.

Explain the difference between renewable and non-renewable resources. In the light of your answer, ho w do you think we should utilize each of these two categories of resources in the future.

Regarding our water and energy resources, give us examples of abuse.

Compare the impact that earlier civilizations (pre-1600) in Southern Africa (hunter-gatherer societies and herders) have had on the environment to the impact that western farming methods are having on it.

List the names of at least 20 places on South Africa that has been named after natural objects like animals, birds, rivers, mountains,  minerals or other natural elements in the vicinity.
Natural Sciences

Our health depends hugely on the quality of food that we eat. The quality of the food we grow from the ground is directly proportional to the fertility of the soil. If we do not have access to these, what symptoms may we display?

But it is not only humans that depend on fertile soil for their well-being – plants also do. What makes some soil fertile and others not?

Explain the role of the four seasons to encourage renewal and growth.

How do we measure wind, rain and temperature?

Explain why some types of soils are more prone to erosion than others.
Economic Management

When the resources that we use are of good quality and the services we receive are reliable then our community is advancing positively and our standard of living as well. Think of ways you can contribute to the well-being of your community by:
• acquiring and growing certain entrepreneurial  skills to supply in specific needs of the community
• alerting government of services and resources that are being abused or are not in good order
Consider the wasteful actions from members coming from high income groups to the actions of people from lower income groups. Compare the amount of electricity and water each consume as well as the amount of waste that they produce.

Identify an entrepreneur in your community that is contributing towards environmental sustainability and human safety. Mention the labour that is required to make his/her venture succeed, the recourses needed and the amount of capital he/she would have to borrow.

Assemble a trolley that could be used to pick up recyclable materials like metal and plastic.

Explain how it could be used to keep neighbourhoods clean and safe and to provide some extra income.

Working with your neighbours, organise a combined effort to dispose of recyclables. Once there are enough contributors recycling companies may be interested in collecting at no cost to you. If you can organise transport to the recycling company some will even be willing to pay for your recyclable items.
