Homeostasis and the Cell Using Mathematical
Modeling

• Team 28
• Memorial High School
• Julie Carpenter, Mary Hobbs,
• Jo Ann Strait, and Betsy Wilkes

2
Purpose

• Enhance student understanding of cellular
  processes and mathematical principles using
• student acquired data
• computational science

3
Objective

• Investigate the processes of cellular transport
• Osmosis
• Diffusion
• Interpret data and investigate functions through
  the use of graphs, equations and mathematical
  models.

4
Module Activities in Biology

• Web-based research on cell membrane and how it
  acts as a gate for the movement of materials in
  and out of the cell.
• Hands-on labs demonstrating diffusion and osmosis
  using Excel to graph data.
• Construction of a Stella model using lab data to
  show the dynamic nature of movement of substances
  into and out of the cell.
• Lab group project to construct or modify Stella
  model to explain what happens to cells as the
  environment changes, i.e., effect of blood
  pressure medication or effect of extended
  physical activity.

5
Module Activities in Mathematics

• Discover the graphs of different functions, using
  scatterplots of imported data in Excel, TI
  Interactive, and the graphing calculator.
• Explore transformations on the graphs, the
  resulting effects on the equations, and draw
  conclusions on how to write the equations through
  the use of mathematical models.
• Extend knowledge of diffusion and osmosis using
  groundwater and water purification activities.
• Compare actual biology lab results using various
  software to determine the best data fit.
