1. To understand the natural world: This involves observing, describing, and explaining natural phenomena through systematic investigation and experimentation. Science aims to develop models and theories that accurately represent how the world works.

2. To predict future events: By understanding the underlying principles of the natural world, science seeks to make predictions about future events. This can involve forecasting weather patterns, understanding disease transmission, or predicting the behavior of complex systems.

These two goals are interconnected. Understanding the natural world allows us to make predictions, and the ability to predict future events can further our understanding of the world around us.
