Our virtual labs and activities serve many purposes. We have designed these open-access activities for individual, group, or classroom use. In many cases the virtual lab module will be most valuable if used in preparation for hands-on lab experience. Virtual labs may also serve as alternatives to lab experiences that may not be possible in the classroom setting because of limitations imposed due to time required for the actual lab, the expense of laboratory equipment, or safety. Our Lab Bench is designed to help students have a hands-on experience and is a part of several modules.
We suggest using the virtual microscope tutorial to introduce students to the basic use of the microscope. Since there is no need to worry about damaging a virtual scope, we save care and handling of the scope for a little later. This will engage students in actual use of the scope early on and they can review these critical steps when they are preparing to handle the microscope in the lab.
Suggested order of Microscopy teaching modules:
Step I- virtual Microscope Tutorial lab (partially developed)
Step II- virtual lab Microscope Use Tutorial (under development)
Step III- hands-on microscope lab (under development)
Step IV- virtual Microscope Measurement lab
Part V- virtual Advanced Microscope Tutorial lab (under development)
Part VI- Microscope Compare (prototype)
Fertilization and Development
*The specific experiment in our virtual lab with the European common sea urchins (Paracentrotus lividus). Has not yet been published. But a similar study using the purple urchin (Strongylocentrotus purpuratus) has been recently published by our partner scientists Drs. Sam Dupont & Michael Thorndyke and their colleagues.Download that study for more information on the protocols and observed impacts of acidified water on sea urchin development.

*For advanced study: part two of the above research, examining impacts of ocean acidification on gene expression in purple urchin larvae. Hot off the press!
