Understanding Gear and System Mechanics

Mr. Andersen introduces systems thinking, emphasizing the importance of understanding how parts work together within a system. He uses a four gear machine and a wooden car's wheel system as examples to demonstrate system modeling. The video encourages viewers to apply systems thinking to various objects, such as a dry erase marker or a water lily, to better understand their interactions and functions.

What is the primary focus when thinking in systems?

• The individual parts

• The size of the system

• The interactions between parts

• The color of the parts

What is the first step in investigating a system?

• Color code the system

• Remove parts of the system

• Define the system

• Play with the system

In the four-gear machine, what happens when the gray gear is moved?

• The gears change color

• The system stops

• The orange gear moves

• The board moves

What is the role of the board in the four-gear machine?

• It measures the speed

• It colors the gears

• It holds the gears

• It powers the gears

What happens if the orange gear is removed from the system model?

• The gray gear moves the blue gear

• The system speeds up

• The gray gear cannot move the blue gear

• The system changes direction

What specific part of the wooden car system is analyzed?

• The car body

• The steering wheel

• The wheel connection

• The engine

In the wooden car system, what secures the wheel onto the bolt?

• The block

• The tape

• The board

• The nut

What is likely to happen if the nut is removed from the wheel system?

• The wheel will become larger

• The wheel will change color

• The wheel will fall off

• The wheel will spin faster

What is suggested as a method to learn about systems?

• Listening to music

• Watching movies

• Drawing systems

• Reading books

Which of the following is an example of a living system mentioned?

• A car

• A water lily

• A dry erase marker

• A four-gear machine
