Science is a systematic way of looking for explanations and connecting the ideas we have. In Science certain methods of inquiry and investigation are generally used. These methods lend themselves to replication and a systematic approach to scientific inquiry that attempts at objectivity. The methods include formulating hypotheses, and designing and carrying out experiments to test the hypotheses. Repeated investigations are undertaken, and the methods and results are carefully examined and debated before they are 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 is making the universe 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 their ways of viewing the world.
