Patterns of Motion Explored Through Pencil Holders

Ms. Fletcher introduces the concept of patterns of motion using pencil holders as examples. She demonstrates how even wheels connected by an axle result in straight motion, while uneven wheels cause a curved path. Students are encouraged to observe and discuss these differences, enhancing their understanding of motion patterns.

What materials does Ms. Fletcher use to demonstrate patterns of motion?

• A ruler and a compass

• A set of colored pencils

• A pair of scissors

• Two different pencil holders

What happens when you roll an object with two even wheels connected by an axle?

• It moves in a circular path

• It moves in a zigzag pattern

• It spins in place

• It rolls in a straight line

What is the difference between the two pencil holders used in the lesson?

• One has a larger wheel and a smaller wheel

• One is heavier than the other

• One is taller than the other

• One is made of metal and the other of plastic

How does the motion change when using a pencil holder with uneven wheels?

• It moves faster

• It curves instead of going straight

• It stops moving

• It moves in a straight line

Which direction does the pencil holder with uneven wheels tend to curve towards?

• It curves randomly

• Towards the larger wheel

• It doesn't curve

• Towards the smaller wheel

What can we learn about motion from the experiment with the pencil holders?

• Even wheels result in straight motion, uneven wheels result in curved motion

• Uneven wheels cause objects to move in a straight line

• The material of the wheels affects the motion

• Objects with even wheels move in circles

What is the main focus of the discussion in the final section?

• The color of the pencil holders

• The patterns of motion with different wheel configurations

• The weight of the pencil holders

• The speed of the pencil holders
