on a river.

Introduction to the Lesson:
Rivers are moving channelized bodies of water that move from areas of high
elevation to areas of low elevation. However a river can also move something other
then water, sediments. Remember that sediments are small weathered (broken)
pieces of rock (baby rocks) that can be eroded (moved) and then deposited (placed
in new locations). River can both erode and deposit sediments. Can I have a
volunteer to hand out today’s laboratory activity.
Students will
 Answer the laboratory practice questions
 The first page will be guided by the teacher and the second page will be
competed independently by students


The faster a river moves the larger the sediments that can be transported
The faster a river moves the more sediments can be eroded
At the outside curve of a meander a river will erode sediments
At the inside curve of a meander a river will deposit sediments
The older a river gets the more meanders it will have
Closing Questions
 On average the Susquehanna River moves at a velocity of _________ what
type of sediments can be transported by the river? What sediments cannot
be transported?
 Other then by meandering, how else do you think the velocity of a river can
be increased or decreased?
