Kidney Dialysis


Create a model of a kidney dialysis machine.

How does a kidney dialysis machine remove wastes from the blood of a patient with kidney failure? Create a mini-model of a dialysis machine.

  • Determine what substances diffuse from the patient into the machine.
  • Determine what substances should be added to the fluid in the dialysis machine to prevent the loss of essential materials.
  • Compare hemodialysis (using a dialysis machine) to peritoneal dialysis (an alternative treatment for kidney failure).

Performance Expectations:

MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

  • Science & Engineering Practices

    Developing and Using Models - Develop, revise, and/or use a model based on evidence to illustrate and/or predict the relationships between systems or between components of a system

  • Disciplinary Core Ideas

    LS1.A: Structure and Function - All living things are made up of cells. In organisms, cells work together to form tissues and organs that are specialized for particular body functions.

  • Crosscutting Concepts

    Systems and System Models - Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy, matter, and information flows within systems.
