How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
