- Things work because different parts or materials interact with each other.
- For example, in a clock, gears move together to show the time.
- In a plant, roots absorb water, and leaves make food, all working together for growth.
- Our bodies also work this way, with each organ having a special job to keep us healthy.
- Science helps us understand how these parts cooperate to make things function properly.
