Finger on the pulse…

One of the other areas I covered in my science workshops at BETT was investigating heart rate and circulation.

There are a number of apps that could be used in the classroom to measure heart rate, and during the workshop I demonstrated What’s My Heart Rate (download the app here, free). During the workshop, I demonstrated how Labdisc could be used to capture pulse rate and cardio graphic data using the pulse meter included with several of the Labdisc models.
This data could then be compared with data from apps such as What’s My Heart Rate


This app uses the front facing camera of the iPad to detect changes in the blood flow through capillaries in the skin. Another app which uses similar technology to measure blood flow in the fingers is Cardiograph (download the app here – £1.49).
Students could compare accuracy of these ways of measuring pulse with more traditional ways. This is very current medical research, where efforts are being focused on whether smartphone cameras can provide accurate medical data, so your students could also be contributing to cutting edge medical research while they investigate heart rate!
