TOPS Chemistry Labs |
|
| The TOPS experiments are designed to integrate
into a teacher's current high school curriculum, conform to the Science
Framework for California Public Schools, and employ a biochemical focus
to enhance and bridge the biology and chemistry curricula. The experiments
employ modern technology including computer driven instruments of the type
used in local industrial laboratories as well as commercially available
data analysis software.
