The third day of the SIFT training week was focused on aquatic systems. The group visited Wolf Run Lake in the morning and Brush Creek in the afternoon. They performed water quality tests at the sites and sampled for organisms in the habitat, recording richness (number of species) and abundance (number of individuals of each species) in their field notebooks. They used these numbers and the species they found to predict whether the systems were healthy or polluted.

After most of the day outdoors, we returned to the Overnight Center where students prepared their presentations on the results of their testing.
Good news -- everyone agreed that both aquatic systems are healthy!
