Discover the power of these tools by conducting scientific explorations, applying matrices to explore properties of the tetrahedron, producing data for statistical analysis with the light bulb lab, and having fun doing art with functions.

 

• The Viscosity Lab 

Explore Stokes equation by modeling real-time virtual data using a virtual laboratory and a TI-83 graphing calculator.

Used with College Algebra students to explore modeling of scientific data and with science students to explore concepts and relationships in Fluid Mechanics.

 

 

• The tetrahedron World

Explore properties of a tetrahedron by performing motions by operating your mouse. Enhance the exploration with the use of distance matrices and their operations.

Used with Modern Algebra students to develop a visual understanding of the symmetrical group for the tetrahedron, this animation also illustrates the use of matrices to describe the group properties.

 

• Smiley the Cat

Create a drawing of Smiley the Cat using parent functions and a TI-83 graphing calculator. This lab provides a fun connection with art.

 

• A Day In The Life Of A Light Bulb    

  A conveyor belt allows the user to produce samples of fluorescent and incandescent light bulbs that are tested in a chamber for “luminosity”, “lifetime” and “color”. By operating a batch selector the user can select random, cluster or stratified samples. Data can then be statistically analyzed to answer the question: What type of light bulb is a better value to consumers?

  This simulation is used with introductory statistics students, and serves as a tool to experience data collection, data analysis and report writing. Instructor materials are currently under production. A Pre-test is available.
