Full-day programs

In a 4 hour full-day program, your group go will on a hike, learn about or visit a long-term research experiment, and conduct their own hands-on field investigation. Some full-day trips require your bus to stay onsite to drive to research areas. Select from the options below.

Ecosystem Comparison

Season: April – November
Note: bus required

Students go on a hike to Cedar Bog Lake (see Biomes Hike above), discuss natural history, and make observations about changes that occur between at biome transition zones (light, temperature, soil, moisture, etc). They also visit the Big Biodiversity experiment (see description in Research Visit options above) to discuss the scientific inquiry process and the value of biodiversity for plant communities. To put these pieces together, they work in groups of 3-5 to develop hypothesis-driven questions and collect basic data on the abiotic and biotic factors along a transect that passes through three ecosystems (prairie, forest and wetland OR forest, swamp, lake). These questions and data allow them to investigate a basic ecological concept: how do the physical elements of an ecosystem influence the distribution of its living organisms, and how do these elements change in space? The day wraps up with groups graphing their data, interpreting their results, and collaboratively sharing insights into the interactions that structure ecosystems.  

Preserving the Oak Savanna

Season: May – October
Note: bus required

Students go on a hike to Cedar Bog Lake (see Biomes Hike above), discuss the natural and scientific history of Cedar Creek, and make observations about factors that impact the health of deciduous forest ecosystems. They spend the rest of the day in our oak savannas, where they visit and view our long-running prescribed burn experiment (see description in Research Visit options above) and discuss how fire can be used as a research and management tool. In the savanna, they also conduct their field investigation. After a chance to plan in small groups, students use a line transect or quadrat sampling to investigate the effects of prescribed burning regimes on savanna plant populations. They develop basic scientific questions, collect data, and graph their data to answer their group’s question. There is time at the end of the day to share out the results of their investigation. There is also ample time to look for some of our savanna specialist species, including the red-headed woodpecker! Depending on availability and teacher interest, a hike to our bison viewing platform may be available as a substitute for the hike to Cedar Bog Lake.

Water Quality

Season: April – November
Note: bus required if going to Fish Lake

Students go on a hike to Cedar Bog Lake (see Biomes Hike above) or to Fish Lake to observe and think about the role water plays in ecosystems, and to collect their own water samples for analysis. All living things need water, from plants to animals to humans. How can we tell if our water is clean and our aquatic ecosystems are healthy? During and after our hike, with plenty of time for questions and observations, we will learn how scientists at Cedar Creek and elsewhere study water quality. Student groups will make hypotheses about which of three water sources at Cedar Creek is the healthiest (and figure out what ‘healthiest’ even means!) and then measure factors like dissolved oxygen, nutrient levels and pH to see how their hypotheses hold up to reality. Depending on season, we may also have the opportunity to sort and identify macroinvertebrates as biological indicators of water quality.

Entomology 101

Season: May – September

Experience the wonderful world of insects! Students will put on their entomologist hats for the day as they explore the structures that allow particular species of insects to thrive in specific habitats. Your visit will include a nature walk with a focus on observing and documenting insects and their habitats, a chance to explore our world-famous insect collection and discuss the science of entomology, and a hands-on investigation to collect and examine live insects! We’ll discuss the connection between structure and function and how it plays out in nature.

Wildlife Ecology

Season: year-round

How do scientists study wild animals, particularly the ones that are shy, scared or rare and thus hard to observe? Spend a day exploring and practicing field methods while learning about on-going research into wildlife at Cedar Creek. Your visit will include an introduction to the art and science of animal tracking including a nature hike and field investigation of wildlife track and sign, hands-on exposure to field methods currently in use at Cedar Creek (depending on group size and time of year, this will include radio telemetry - invented at Cedar Creek! - , camera traps, or both), and plenty of time examining our collection of pelts, bones and skulls. As available, you may also have the opportunity to go birding and learn about our red-headed woodpecker research project, view our seasonal bison herd and/or assist in insect surveys.

Half-day programs

In a two-hour half-day program, your group will learn about Minnesota’s biomes and visit one of our long-term research experiments. All half-day visits require your bus to stay onsite to drive to the research areas. Select from the research visit options below.

Biomes of Minnesota— included in all half-day field trips

The Cedar Bog Lake trail is a unique experience that lets students walk through representations of all three biomes present in Minnesota before emerging at the shores of Cedar Bog Lake. Deciduous forest, tallgrass prairie and boreal coniferous forest, as well as swamps and a lake – they all contribute to make this a “Walk Across Minnesota!” Students discuss the natural and scientific history of Minnesota and Cedar Creek, and observe and document the biotic and abiotic components that structure our local ecosystems through drawing and writing. Total distance is ~1 mile.

Research visit

Select one of the following options

Big Biodiversity

Dr. Dave Tilman’s Big Biodiversity experiment is known worldwide for its insights into the way prairie plant communities function and its role in helping scientists, policy makers, and the general public understand and appreciate biodiversity. Explore this enormous experiment using a guided scavenger hunt that encourages students to figure out Dr. Tilman’s main results on their own. We’ll leave with an appreciation for biodiversity and science that’s hard to replicate anywhere else!

Forests and Biodiversity (FAB)

The Forests and Biodiversity (FAB) experiment is Cedar Creek’s newest look into the importance of diversity for plant and animal communities. Depending on your interests, you will learn about the scientific process, practice using a dichotomous key to identify tree species, discuss the many ways scientists measure diversity, and/or explore a field with 40,000 trees planted by fellow students.

BioCON – global change experiment

Large-scale changes in carbon dioxide, temperature, rainfall, nitrogen levels and biodiversity are happening across the globe. Cedar Creek is home to one of the longest-running experiments in the world in investigate how these many varied factors impact plant community health, growth and resilience. Visit the BioCON experiment to learn about how plant communities are responding to a changing world, helping us deal with human impacts to natural systems, and more! We’ll also discuss the scientific inquiry process, the engineering design process, and brainstorm additional questions and methods we could use to investigate the world we live in.

Oak Savanna and Prescribed Burn experiment

Most people think of wildfires as something to be extinguished as quickly as possible. However, for some ecosystems like the oak savanna, fire is a critical part of a healthy environment. Cedar Creek is home to a prescribed burning experiment that has been running since 1964 and has taught us about the value of fire to plants and animals in these special ecosystems. Visit the savanna section of Cedar Creek’s property and experience the dramatic difference between areas that are burned every year, burned occasionally, or never burned. Depending on group size and time of year, this tour may also include the opportunity to view our bison herd from the bison viewing platform

In-school visits

Our capacity to do in-school visits is limited, particularly in September, October, and May. However, if you would like one of our scientists or naturalists to speak to your students at a career panel or event, assist with judging at a science fair, or provide input in a similar capacity, please let us know. Contact Kara Baldwin (baldwink@umn.edu) and we'll see what we can arrange.
