Thinking in Structure and Function - Level 2 - Complex Structures

Mr. Anderson introduces the concept of complex structures in the context of structure and function. He uses examples like a rack and pinion and an adjustable spanner to demonstrate how multiple structures work together to achieve a specific function. The video emphasizes identifying systems, understanding the relationships between components, and analyzing the impact of removing parts. Students are encouraged to apply these concepts to other complex structures like a can opener or the cardiovascular system.

What is the first step in analyzing a complex structure?

• Listing all possible interactions

• Identifying the system to investigate

• Determining the overall function

• Identifying the materials used

In a rack and pinion system, what is the primary function?

• To rotate the pinion

• To adjust the gear size

• To move the rack back and forth

• To secure the board

Which component in the rack and pinion system is responsible for holding the pinion and rack in place?

• The gear

• The rack

• The board

• The pins

What happens to the adjustable spanner when the worm screw is removed?

• The fixed jaw moves

• The handle becomes loose

• The adjustable jaw cannot be adjusted

• The jaws remain fixed

What is the overall function of the adjustable spanner?

• To measure distances

• To hold objects in place

• To adjust jaw sizes

• To tighten screws

Which part of the adjustable spanner is considered an internal structure?

• The handle

• The pin

• The fixed jaw

• The worm screw

What is the key takeaway when analyzing complex structures like a can opener or cardiovascular system?

• Understand the interaction of structures for a specific function

• Identify the largest component

• Focus on the materials used

• List all possible uses
