FRESH Field Trip #2
A student's part of the experiment. Holding the measuring tape and timing the flow of the stick.
FRESH crew throws a stick in the river to measure velocity of the river. 
Our model of Grand Rapids showing the Grand River and its flow direction, which is west! 
Studying the dynamics of a river, its erosion effects, and what happens to waterfalls. Also, this would make SUCH a great beach! 
This is basically calculating discharge, which is kinda getting old... 
Two kids taking a lead in the hike to our destination, the Grand River. 
Taking a long walk through the field to the moraine - composed of unsorted sediments, specifically till. 
Viewing the inside of a temple-like shrine. Actually it's an oversized grave for an important person. I wonder who???
Students trying to locate the Grand River and its tributaries on the glacial map of Michigan. 
Again, more calculations, but for the discharge of the actual Grand River we calculated on our field trip. We used the velocity along with the width and depth of the water. 
Here's where we discussed the sediment called outwash. 
Our second miniature river experiment showing how a river washes away all of the silt and clay, and the remains are left as sand and gravel. 
Map of the city of Grand Rapids, which shows how the Grand River flows right through it, etc. The red areas indicate the buildings, companies, and such.
This is what the Grand River looks like when it is flooded. Aw, no swimming today? 
Class notes - End moraines form when glaciers melt as fast as they move down the slope.
An up close view of a bass fish, how exciting!
Checking for fish under the waters of "No Name" Lake, as well as any other creatures. 
The man is talking about the weathering of certain items, such as stone, and how mold grows on it. So features, like carved names and such, fade away.
These are some of the measurements we made during the FRESH Program to find the turbidity and conductivity of the water. 
This is a drawing showing the gravel, sand, silt, and clay from our miniature river experiment.
Our student lunch, not much to say aside from the taste of the sandwich. 
Back at campus, we identify the deposits of a miniature glacier. 
This is us trying to identify certain points in our city like our school, graveyards, houses, and playgrounds. 
This is a drawing representing the deposits of a glacier.
*Green= Moraine
*Red=River (outwash)
*Blue= Lake
This is a sketch of the ridge that we hiked onto. It is an end moraine.
