Spreadsheets Across the Curriculum module/Geology of National Parks course. Students examine the histogram of a positively skewed data set and calculate its mean, median and mode.

Lake Investigation: Determining Lake Type and Health Using the Internet part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an on-line research activity in which students research different Minnesota lakes and determine their physical characteristics, chemical characteristics, and the overall health of the lake.

Using line transects to determine interrelationships between vegetation type and small mammal activity. part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Using quadrats along line transects in two different habitats, students will gather data which will provide evidence that shows the interrelationships between vegetation types and small mammal populations

Investigating water quality through quantative and qualitative analysis of benthic macroinvertebrate sampling. part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In activity is a Biology field lab where students will investigate the relative health of an aquatic system based on bioindicators. Students will then summarize and reflect upon their findings.

Investigating Biodiversity in your schoolyard part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this field lab students will investigate the biodiversity around their school. Students will perform a biodiversity count using transect line. The students will develop multiple hypotheses relating to biodiversity and propose additional procedures for studying, collecting and testing these questions.

Investigating the Water Quality of the Root River in Lanesboro, MN part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a field investigation where students collect and design an experiment to identify the water quality of a section of the North Branch of the Root River in Lanesboro, MN. The investigation is done in collaboration with Eagle Bluff Environmental Learning Center.

Investigating the Ecology of Goldenrod Galls through Biological Sampling part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a field investigation where students conduct biological sampling on goldenrod galls and form conclusions.

Investigating Aquatic Ecosystems: Macroinvertebrates and Water Quality part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a field investigation and comparison of three aquatic ecosystems.

Ecosystem Change and Insect Visitation Rates part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an open-ended inquiry investigation in which students analyze and predict how an environmental change will affect the visitation rates of insects. Students will ask a question, develop multiple hypotheses, run a scientific investigation, and report their findings to their "colleagues".

Using Simpson's Reciprocal Index to Identify and Compare Habitat Biodiversity part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a field investigation where students will compare the biodiversity of two separate habitats based on the collection and identification of insects.

Outdoor Light Sources and their Attractibility to Nocturnal Insects part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this field exploration, student teams (consisting of 3 students) will investigate whether incandescent, fluorescent or a no light situation will attract the most nocturnal insects.

Determining School Population Using Multiple Student Driven Methods part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an introduction to population sampling techniques. Students' will identify weaknesses and strengths of a variety of techniques and determine the best applications of the various methods identified.

Using Benthic Marcoinvertebrates Captured by Rock Baskets to Determine Biodiversity in a River. part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this ecology investigation, students will build and place rock baskets to collect benthic macroinvertebrates in a local waterway. They will observe and identify their macroinvertebrates and use the data to determine the pollution tolerance index for various areas of a river.

Using Plant Surveys to Study Biodiversity part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a field investigation in which students conduct a plant survey of two study plots, analyze their findings through graphing and mathematic models, investigate the impact of human activity in the general area (optional) and generate questions for further investigation of the study plots.

Determing the health of an acquatic ecosystem by identifying macroinvertebrates part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This lab activity allows students to indetify macroinvertebrates and determine the health of an acquatic ecosystem.

Macroinvertebrates and Indicators of Water Quality part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a field investigation where students can go to a body of water and collect the macroinvertebrates there and identify them. Based on what they find, they can assess the water quality by determining the biotic index.
