INTRODUCTION TO NATURAL SCIENCES

 

 Science is a systematic way of looking for explanations and connecting the ideas we have.

In Science inquiry and investigation methods are generally used. These methods lend themselves to replication and a systematic approach to scientific inquiry that attempts objectivity. The methods include formulating hypotheses, designing and carrying out experiments to test the hypotheses. Repeated investigations are undertaken, the methods and results are carefully examined and debated before being accepted as valid.

Science also explores the frontiers of the unknown. There are many unanswered questions such as: Why is climate changing around the world? What makes the universe to expand? What causes the earth’s magnetic field to change? As with all knowledge, scientific knowledge changes over time as scientists acquire new information and people change how they view the world.

Natural Sciences are all around us – they are the means by which we observe, understand and manipulate the physical world for the benefit of humanity. Natural scientists combine depth of specialised knowledge with breadth across traditional subject boundaries to create innovative solutions for urgent natural, business and industry problems.

INDIGENOUS KNOWLEDGE SYSTEMS AND NATURAL SCIENCES

Our predecessors made careful observations, recognised regular patterns in seasons, the life cycles of plants, and the behaviour of animals. They understood many of the relationships in the environment in which they lived. This included knowledge about agriculture and food production, pastoral practices, animal production, forestry, plant classification, medicinal plants, management of biodiversity, food preservation, management of soil and water, iron smelting, brewing, making dwellings and understanding astronomy. As society changes, some of that knowledge is being lost. Biologists, pharmacists and archaeologists are pursuing and recording it before all is lost forever.
