It is very important in our studies as it enhances our knowledge and let us find out the solution when we encounter difficulties. We will be able to apply what we learnt in other areas as well.
When we are not familiar with a new topic and find difficulty to understand it, researching online could help us to clear our doubts.
We can just research about the topics that we are keen to know mare about to benefit our own studies. For example we could research about the properties of materials for a project like building a car to know which of the materials is most suitable.
