The Citric Acid Cycle is a metabolic pathway that uses a two-carbon molecule, and a four-carbon molecule to form a six-carbon molecule that is used to produce NADH, carbon dioxide, ATP and FADH2. The cycle involves eight chemical reactions, and at the end, the original four-carbon molecule is produced. This animation gives an overview of the reactions and products involved in the pathway.

The BCcampus Open Education Virtual Lab and Science Resource Directory lists free science resources designed to support remote science education. This directory is updated as new resources are identified. Note that, while all resources in this directory are free, not all are open. Resources that carry Creative Commons or otherwise open licences are clearly labelled.

Paul Andersen describes the important characteristics of viruses. He starts with a brief description of origin theories. He then describes the two characteristics of all viruses; genetic information and protein coats. He also describes how some viruses use specialized envelopes to gain entry to their host cells.

For this maker challenge, students become biomedical engineers who design, create, and test a medical device that measures a patient’s pulse using a microcontroller, LED, and light sensor. Students use data collected from the device they build to determine how to best visualize the results, so that a doctor can view the patient’s pulse on the computer screen. During the challenge, students learn about basic coding, the capabilities of microcontrollers, how sensors gather data, how the human circulatory system works, and how to plot real data. Finally, students are challenged to make their systems portable so that they create wearable health technology. This is a great project for a high school senior design team project.
