Thinking in Structure and Function: Level 4 - Structures at Varying Scale

Mr. Anderson explains the concept of structure and function at varying scales, focusing on Velcro and Band-Aids. He demonstrates how to identify systems and analyze them at both macroscopic and microscopic levels. The video encourages viewers to explore the relationship between structure and function, using examples like Velcro fasteners and flexible Band-Aids, to understand how microscopic details can explain macroscopic behaviors.

What is the first step in investigating structure and function according to the video?

• Identifying the system

• Testing the material

• Observing the color

• Measuring the size

What are the two sides of Velcro described as at the macroscopic level?

• Hard and flexible

• Soft and rough

• Transparent and opaque

• Smooth and sticky

At the microscopic level, what structure is found on side 1 of Velcro?

• Plastic loops

• Rubber bands

• Metal hooks

• Cotton fibers

What is the unique feature of the Band-Aid's fabric at the macroscopic level?

• It changes color

• It is waterproof

• It stretches in one dimension

• It is adhesive on both sides

What allows the Band-Aid to stretch in one dimension at the microscopic level?

• Elastic bands

• Flexible white threads

• Metal wires

• Plastic sheets

Why is it important to change the scale from macroscopic to microscopic?

• To see the color differences

• To test the durability

• To measure the weight

• To understand the detailed structure and function

What other examples are suggested for applying the concept of structure and function?

• Animal fur and bird feathers

• Insect wings and fish scales

• Human bones and muscles

• Geared legs in a plant hopper and plant cell organelles
