| Description | This activity can be used in the classroom to introduce students to the difference between saltwater and freshwater organisms. Students gain experience in planning experiments, utilize their problem solving skills, and work cooperatively. The students are faced with a problem...it is the year 2025, the earth has stopped spinning, the sun shines constantly, and all the water is running from lakes and streams to the oceans. As "environmental scientists," how will they save the freshwater organisms? Upom completion of this activity, students will be able to realize the importance of niches in an ecosystem and learn about the physiology that allows freshwater organisms to survive in freshwater and saltwater organisms to survive in salt water. | |||

It appears one would need some prep time to set up the lab but the activity is a good one.

This resource will be used shortly in my classroom. It does not cost money, and the students are asked to devise their own protocol within parameters that are reasonable. This is great as an introduction lab as well in order to let students know what kinds of investigations they will be doing throughout the year.

This resource has promise for engaging students in the kind of science required by NGSS science practices. I like the fact that students are designing their own experiment but I think the guiding question needs to be more explicitly stated.
