What if students could BOTH design structures to withstand
earthquakes AND use mathematics to design
earthquakes which will destroy those structures?
Learners design and test mathematical functions to produce
dynamic displays of up to 16.7 million colors
Smart Cart: The
LACI Smart Cart in action, first as a CNC-style machine and
then as an extension to "Graph Match" activities--but
using actual algebraic functions in addition to conceptual
a Laser: A hands-on activity using linear and quadratic
functions to produce uniformly accelerated motions
Simulator: A hands-on activity using the incredible power
of logarithmic functions
or Bacon?: A hands-on activity using piecewise-defined
functions and uniformly accelerated motion
Design with Moment of Inertia:
Rotate objects as rapidly as possible without breaking.
Learners compare and test alternative functions of speed
vs. time to drop pennies in specified targets.

What questions can you add?
few students think of algebra and trigonometry as exciting and practical
subjects, but a simple control system project can improve their views
