Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan (link is external) on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform (link is external).

Exploring the Great Lakes


As rain falls all over Michigan, the water gathers in small local watersheds, which feed into larger regional watersheds, which ultimately feed into the Great Lakes. Water that falls on the land in Michigan eventually flows into one of the Great Lakes because the elevation of the Great Lakes is generally lower than the elevation of the land in Michigan. Students will be able to use elevation maps to study water flow from watersheds emptying into the Great Lakes. Success with this lesson will happen when students can investigate the Great Lakes water flow and produce a simple diagram that illustrates this flow pattern.
