Students rebuilt sections of a non-functioning interactive exhibit originally designed and built by the Lawrence Hall of Science in the 1970’s.  Students performed an analysis of the system to determine how the exhibit was originally designed to function. Then, the students worked to specify and purchase modern components, then rewired and installed new components.  The project also involved removing the exhibit module from the display case at the zoo, moving it to SCU for repairs, and then moving it back to the zoo to be re-installed and re-connected to power.
