Natural Sciences - Term 1 - Week 7

A system is a group of parts that work together to achieve a common goal. Structures are the physical components that make up these systems. For example, a school is a system that includes various structures like classrooms, libraries, and playgrounds. Each part plays a role in the overall function of the school, just as each part of a machine contributes to its operation.

Consider a bicycle as a system. It consists of various structures such as the frame, wheels, and pedals. Each of these parts must work together for the bicycle to function properly. Another example is the human body, which is a complex system made up of structures like bones, muscles, and organs, all working together to keep us alive and healthy.

In groups, students will discuss different systems and structures they encounter in their daily lives. Each group will list at least three examples and share them with the class. Encourage students to think about how these systems and structures interact and depend on each other. For instance, how does the structure of a house support the system of a family living in it?

Students will create a simple model of a system using materials available in the classroom. They can choose to build a model of a water cycle, a food chain, or a simple machine. Each student must label the structures involved and explain how they work together as a system. After completing their models, students will present their projects to the class, highlighting the key vocabulary and concepts learned.

• A single part that functions alone
• A group of parts working together
• An unconnected collection of items
• A type of structure

Answer: A group of parts working together

A system consists of multiple components that interact to achieve a specific purpose.

• A bicycle
• A classroom
• A family
• A computer program

Answer: A classroom

A classroom is a physical space that is part of the educational system.

Answer: A transportation system.

Transportation systems include roads, vehicles, and traffic signals that work together to move people and goods.

• They are unnecessary
• They support the system's function
• They complicate the system
• They are always visible

Answer: They support the system's function

Structures provide the necessary components that allow a system to operate effectively.

Answer: A bicycle is a system because it has various parts like wheels, pedals, and handlebars that work together to allow a person to ride it.

Each part of the bicycle contributes to its overall function, making it a system.

• A process that changes over time
• A physical component of a system
• An abstract idea
• A type of energy

Answer: A physical component of a system

Structures are tangible parts that make up a system.

Answer: Structures are the parts that make up systems.

Without structures, systems would not have the components needed to function.
