The virtual ocean acidification laboratory includes background information on pH and ocean chemistry, an interactive model of ocean acidification, a comparison of calcifying organisms and an interactive evolutionary tree of calcifying organisms, and a virtual laboratory where students address the question: How does ocean acidification effect sea urchin larval development?
In the virtual lab, students complete the procedural steps of the experiment: setting up replicate cultures, feeding the larvae, making water changes, and observing the changes in the larvae over time. Then, they set up slides for measurement (morphometric) analysis. The students make the larval measurements themselves of a subset of the larvae (a different subset for each student), calculate the treatment means, and then can then compare their subsample results to the entire statistical sample. The data the students analyze are actual data addressing this question gathered by I2I scientists Sam Dupont and Michael Thorndyke.
