Adipose Tissue: Virtual Microscope
First-year biology. Views detailed slides with a microscope and explores types of adipose tissue. It would require some more activities, such as review type questions to make it into a standalone lab. Could use it as a supplement to an introductory lab on tissue types.
Body Tissues under the Microscope
Introduction to tissues. See five tissue types under the microscope, such as epithelial, muscle, and nervous tissue. Good resolution for the images, but a not enough for a lab: good supplemental material. Requires a free Open University account.
Introduction to cell biology. Decent introduction to lab equipment for cell and molecular biology, such as micropipettes, cytometers, thermocyclers, incubators, etc. The introduction is a bit silly, but push through: it gets better.
Collaborative Rabbit Genetics Lab
First-year biology. This is a fun little simulation that could help teach some basic genetic concepts (homozygosity, heterozygosity, dominance, etc.) using rabbit coat colour and ear type. Good for an introduction to genetics.
Colour Vision (PhET) (CC BY)
First-year biology. Learn the basics of photons, monochromatic light, and the red, green, and blue light photoreception by cones of the retina of the eye. Could be used as part of a first-year lab on sensory reception.
This involves investigation into the genetic basis for different bacterial strains. Uses several large but detailed files. Requires a free BioQUEST account.
Second-year genetics. Walks students through the steps of comparing the genes being expressed in different cell types. The sounds that accompany the animation are silly, but could be turned off. Can isolate mRNA. This is not an experiment we could do in our labs easily, so it would be a good introduction to a microarray. Requires Flash.
First-year biology or second-year genetics. Good introduction to use of spectrophotometer, used in this case to measure absorbance of DNA at 260 and 280 nm. Requires a free Open University account.
Gene Machine: The Lac Operon (PhET) (CC BY)
Second-year genetics. Fun little simulation of the lac operon. Good visual aid for explaining the operon.
Great for understanding genetic drift mathematically.
How to Extract DNA from Anything Living (some permissions)
Walk-through of how to extract DNA from any living thing at home.
Lactase Enzyme Simulation with Data Analysis (CC BY-NC-ND)
From the site: “The goal of this simulation is to understand three factors (the initial amount of glucose, pH, and temperature) that affect the rate that the enzyme lactase converts lactose into glucose and galactose.” Requires Flash.
Leaf Structure as Environmental Indicator
Botany. This is a nice overview of leaf structure in different environments. Has good images and activities with a little quiz. Could be used as part of a plant or photosynthesis lab. Requires a free Open University account.
