Preliminary Practice

Footprints

  

In this lab we analyzed footprints. Everyone in the group stepped into a bin of lightly mixed soil and we analyzed the footprint by measuring and recording markers in the print. From the size of the print you can discover shoe size, and thereby, height of the suspect. Here is my shoe information:
