# Conversions and Engineering at a Paper Mill

Conversions and Engineering at a Paper Mill

Overview / Description: This lesson goes over some basic elements of engineering and the paper making process. We will be using the circumference of a circle and conversions to program motors to make sure the dryer cans are going at the correct RPM's to ensure the paper machine functions correctly. This is a lesson that can be self taught or can be teacher led.

Learning goals/objectives:

After completing this activity, students should be able to . . .

1) Find the circumference of a circle when given a radius or diameter

2) Convert production rate (linear rate) to RPM's

3) Use conversions to find RPM's from the shaft of the dryer can and the shaft of the motor

B-LS 1. Demonstrate critical-thinking skills to make informed decisions

B-LS 8. Actively engage in challenging coursework

B-SS 6. Use effective collaboration and cooperation skills

Content Standards:

# HS.N-Q.A.1

Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.

Materials: The lesson and practice problems are attached below

Assessment:The activity assessment/homework is attached below (pg. 3 and pg. 5)

Wrap-Up: Correcting the assignment and answering any questions

Extension Activity (for intervention or enrichment): You could find the RPM's of a car's tire when it goes different speeds, and find how the RPM's change when the size of the tire changes.

ATTACHMENTS: Below are the notes (pg. 1,2,4) and formative assessment (pg. 3,5) of their knowledge.
