Investigating Macroinvertebrates: How Clean is Our Lake? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this outdoor field study, students will collect and identify as many types of macro invertebrates that they find in Lake Bemidji using an identification key. Additionally students will create investigable questions regarding the macro invertebrates and conduct research to answer their questions. Finally, the students will make a general determination as to the cleanliness of Lake Bemidji by using a chart which identifies the sensitivity level of macro invertebrates to pollution.

A Bug's Life: Under A Rock! part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this classroom biology lab, students will investigate the role or purpose of decomposers. After collecting and observing a decomposer, the pill bug, the students will create habitats that they believe will sustain the bugs over time and will also continue to monitor and observe them throughout the school year.

Sorting Our Way to pH part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection

After practice and discussion, they will then sort food items; first based on their five senses, then by studying their reactions when placed in red cabbage juice. Students document their predictions, observations, the results of their work and their conclusions.
