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 Water Quality

Description: 

There are many different ways to precisely measure the quality of water in a river. Environmental scientists and volunteers all over the state of Michigan are continuously collecting measurements of the quality of water in rivers, streams, and lakes. Students will look at two of these measures to see how they change with location around the state and along a river. The first measure of water quality is called “water conductance” - that is, how well a water sample can conduct electricity. A higher water conductance generally means lower water quality. The second measure of water quality is “pH.” pH is a measure of how acidic or basic water is. Successful students will be able to interpret and analyze data using these two measures to better understand Michigan water quality.
