Skin Sensitivity Investigation Homunculus Mapper

Sharing a link to "The Homunculus Mapper" - a website that includes a full investigation using two point discrimination, to map the sensitivity of the skin at different parts of the body.

Students first need to make a simple "poker" using card and toothpicks. (template included on website). They can work in groups of three (a test subject, an experimenter and a data collector) to carry out the investigation. The really fun part is that students can then enter their results on the website to create their own homunculus.

My accompanying powerpoint and worksheet included.
