Final answer:
Representational systems can overlap across different domains and are not restricted to separate areas. They include methods like models or diagrams and help convey complex information, bridging multiple scientific disciplines.
Step-by-step explanation:
Representational systems can indeed overlap; they are not confined to separate domains. In education and various scientific fields, representational systems refer to methods of conveying information or explaining concepts, often in the form of models or diagrams. As students learn to describe representations and models of natural or man-made phenomena, they can observe that such systems are interconnected. For example, a weather model might include aspects of physics, chemistry, and biology, overlapping across these scientific domains. The ability to describe models of systems effectively is a crucial skill in many disciplines as it allows for a deeper understanding of how different aspects of knowledge are related.
