Mr. Andersen introduces observational patterns, emphasizing the importance of defining systems and using senses to identify regularities. He uses a prism to symbolize patterns and demonstrates pattern recognition in a three-gear machine and seashells. The video encourages using vision, touch, and sound to explore patterns in everyday objects and nature.

What is the first step when looking for patterns in a system?

• Identify the colors

• Use all five senses

• Define the system

• Start by observing the weather

Why is a prism used to represent patterns in the video?

• It is colorful

• It is easy to draw

• It has five sides representing the five senses

What is the first sense used to identify patterns in the three-gear machine?

• Sound

• Touch

• Vision

• Taste

What pattern is observed when the gray gear is moved in the three-gear machine?

• All gears move in the same direction

• The orange gear moves in the opposite direction

• The blue gear stops moving

• The gray gear changes color

What material are the gears in the three-gear machine made of?

• Metal

• The cockle shell

What sense is used to determine the texture of the seashells?

• Sound

• Touch

• Taste

• Vision

What does the pitch of the seashells tell us?

• Their color

• Their internal structure

• Their weight

• Their age

What is the primary goal of identifying observational patterns?
