What is the LaboratoryToolbox? The LaboratoryToolbox is a Hypercard Stack which originated as a tool for teaching laboratory computing. It implements an object oriented "Laboratory Notebook" structure for the acquisition and management of sensor based data within a laboratory environment. The LaboratoryToolbox Stack is organized to support hypothesis testing. The home stack spawns Project stacks which organize the information and data objects which support the test of a hypothesis. Each Project Stack can spawn Experiment cards which organize the information and a set of Trial cards of a particular method for testing the hypothesis. Each Trial card organizes a set of Data Objects which support or trash the particular method of testing the hypothesis. This stack is the product of a class project in the course Biological Laboratory Computing The Department of Biology and Marine Science Center Northeastern University, East Point, Nahant, MA 01908 Instructor: Dr. Joseph Ayers Internet Address: lobster@nuhub.acs.northeastern.edu Teaching Assistant: Jan Witting
