--We learned how to make a river cross-section by taking the depths across Centennial Brook.
--We measured the slope of the riverbed.
--We found the speed of the water by floating different objects a certain distance down the Brook.
--Finally, putting all of our measurements together, we calculated the flow of the Brook in cubic ft/sec.
We looked for insects in the Brook, try to catch them (if we could!) to study and identify them in the bucket. Certain insects in a river indicate whether or not the river is "healthy."
We identified wetland plants such as joe pye weed, arrowhead, cut grass and others. When we couldn't identify a species we looked it up in a book!
We learned about surface tension in this paint, water and soap experiment!
You can imagine the smell of gallons and gallons of sewage!
Wanna closer look?!
