Science: Investigating the nervous system

At Avasara we’re excited about giving the Leadership Fellows opportunities to engage in discussion and practical exploration of what they learn in school. This week, Tamara challenged the Fellows to design an an experiment to determine which parts of the body are the most sensitive to touch. After being introduced to the topic in the first lesson, in depth discussions ensued as the girls explored ways to test for skin sensitivity….

The following day, girls came to science armed with compasses, and tested each other for sensitivity to touch.  They carefully measured the smallest distance at which the points of the compass could be felt as two distinct points…. this involved a fair amount of trust and professionalism as the girls were using each other as scientific subjects!

The next lesson we got down to the serious business of analysing data, and working out which part of the body is the most sensitive.  After answering questions to help develop their understanding of the experiment and the nervous system, girls had to draw (rather amusing) diagrams to show which parts of the body are the most sensitive:

Overall, three fun lessons learning about the nervous system and the scientific method.
