Scientists use their senses to see, smell, hear, taste and feel the world around them. They then make guesses about what might happen or about the way things work by using their brains to ask questions like "What is going to happen next?" or "Why is this happening?" or "What is this composed of?"
Scientists get a lot of data through observation.
...to make predictions. Scientists will then compare their predictions to what happens in the real world. If their predictions equaled what happened in reality, the model is good. If the predictions were different, the scientists know they have to refine the model to better predict what will happen.

Scientists can use computer simulations, mathematical models, and observational studies to test predictions for situations where experiments are impossible or unethical. These methods allow researchers to make predictions based on existing data, theories, and principles without conducting actual experiments.
making an observation
Scientists use observation and experimentation to learn about the natural world.

Scientists often use observation to find out which animals use internal or external fertilization. If direct observation isn't possible, they may look to closely related species to make an educated guess about the lesser-understood species' fertilization method.
You can use it to make trades based on your predictions. Some systems may also help you make predictions.
