Biology Labs Online vs Case It!

Biology Labs Online is a free web collection of 12 interactive biology simulations and exercises for college and AP high school students. Topics include inheritance, evolution, genetics, population growth, protein structure and function, electron transport, plant physiology, cardiovascular homeostasis, and enzyme biochemistry. The inquiry-based activities are designed to reinforce scientific methodology, including principles that may be dangerous, expensive, or time-consuming to study in wet labs. They are not intended to replace traditional labs, operate as standalone tutorials, or serve as online courses. Older Java applets are converted to JavaScript through CheerpJ, a process the site says can have minor quirks. The listed tested browsers on Windows and Mac include Chrome, Firefox, Edge, Opera, and Brave, plus Safari on Mac. The applets assume mouse input and do not work well on mobile devices. Many can export data and graphs, but pop-ups must be allowed for the output window to appear. Notebook data must be exported locally or copied elsewhere to preserve it. Instructors can request access to instructor resources by email.

Case It! is a free framework for collaborative case-based learning in molecular biology. Its v705 software simulates laboratory procedures on DNA and protein sequences, including PCR, qPCR, gel electrophoresis, restriction enzyme digestion, ELISA, microarrays, and Southern and Western blots. It supports plasmid DNA, labelled gels, and locating restriction enzyme sites, including Cas9 sites, in double-stranded DNA. Connections to bioinformatics software and websites support sequence alignment and tree-building, and sequence search is listed as useful for undergraduate research. The download includes DNA and protein sequences cited in case descriptions on topics such as genetic and infectious diseases. Case It Mobile presents selected cases through scenarios and videos of simulated procedures on phones and tablets. Cases not converted for mobile and custom sequences require v705. The project says v705 runs on current Windows and Mac systems and documents an M-series Mac setup using UTM and Windows 11 Pro. Educational users can download it free after submitting a form.
