NANSLO Remote Lab Activity: Membrane Osmosis

This NANSLO lab activity is self-contained and can be used in first semester general biology with lab and survey of biology courses. In this activity, structures of cells are observed through a microscope after exposure to hyper, iso, and hypotonic sodium chloride solutions. The lab activity includes background information on the basic principles of molecular vibrational movement, molecular movement within a cell, and discusses several types of passive transport The lab activity includes lab exercises.
Primary Material Type:

Quality Note:
Curriculum expert in this discipline worked with Discipline Panel of faculty to define learning objectives needed for this lab activity. During development, teleconferences were held to discuss lab activity being developed. Draft activity was posted to listserv for review by Discipline Panel and other faculty in that discipline. Based on feedback, lab activity was modified prior to posting as final. Experts in remote web-based science labs who are also science faculty worked together to define the web-enabled interface design used by students to perform the lab activity via the Internet and created the lab setup (robotics, scientific equipment, and items needed to complete the lab activity) testing it with lab technicians and others prior to launching the final lab activity.
Quality of Subject Matter was assured by:
