In this activity students investigate soil pH differences and buffering capacity as it relates to acid rain, interpret and present their findings, and develop a new, experimental question.

This activity is a classroom quick lab where students explore sand, soil, and water in relation to absorption and permeability.

This activity is a guided inquiry investigation where students gather data on which soil is the best for growing plants. Student will interpret their data, and develop a conclusion from the data. The student will determine which type of soil they would like to use in the next activity of making their own terrariums. The data collected could lead to further questions, which can be investigated in some extension activities.

This guided inquiry is a laboratory investigation on soil textures where students gather and analyze data, compare findings and develop new experimental questions.

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.

This activity is a classroom investigation of wolf behavior where students use observational evidence to identify and describe wolf pack structure.

This activity is a field investigation where students conduct biological sampling on goldenrod galls and form conclusions.

In this activity learners investigate the link between ocean temperatures and hurricane intensity, analyze instrumental and historical data, and explore possible future changes.

In this investigation, students gather biotic and abiotic data and samples in the field, develop an experiment to test another abiotic factor in the lab, synthesize group data, interpret their findings and make a claim on the health of the wetland ecosystem.

This activity is an outdoor lab in which students investigate the process of evaporation, record their findings, and use the data to make connections to the environment around them.

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.

This activity is a field investigation where students list plants and animals they observe. Students will organize their data as producers, consumers, or decomposers and create a food web showing how they affect each other. They will predict what will happen if the food web becomes imbalanced by extinction or over population.

Students will explore wetland hydrology and biology and decide whether or not to restore a wetland or retain dams and drainage systems.

Students author a presentation to the Grounds Management Committee of their school giving their recommendation for the control of the invasive species purple loosestrife (Lythrum salicaria) on campus.

This short video illustrates how warming ocean temperature is a major factor in climate change, particularly the increase in severity of extreme weather (notably storms and drought).

Data-centric activity where students explore the connections between an observable change in the cryosphere and its potential impact in the hydrosphere and atmosphere. Students analyze the melt extents on the Greenland ice sheet from 1992-2003. Students also learn about how scientists collect the data.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Ruminants are the only animals not dependent on dietary amino acids as a source of nitrogen. They have ureolytic bacteria in their rumen that hydrolyze urea into ammonia and use it as a nitrogen source. However, very few ureolytic bacteria have been isolated and studied in pure culture to date. To close this gap, researchers established and used a new integrated approach on bacteria from cattle rumens. They started with urease gene (ureC) guided enrichment and then embedded single cells in agarose microspheres for in situ cultivation. This allowed them to isolate and characterize diverse ureolytic bacteria with demonstrated urease activity. The researchers sequenced a subset of the isolated bacteria and found 28 strains from 12 species with urease genes. These bacterial species had not previously been found in the rumen, but this team detected them in metagenomes from 6 ruminant species. The new strains contained unique genes compared to known related strains, indicating new metabolic functions..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This lesson will introduce students to environmental issues. Students will recognize environmental opinions and perspective, which will help them define themselves and others as either preservationists or conservationists. Students also learn about the importance of teamwork in engineering.

This video, adapted from material provided by the ECHO partners, provides a portrait of IŰ__ŒóíŠupiaq whaling as a community activity, as told through the story of one hunt.

A "Just in Time Teaching" question about he scientific method with follow-up class room activities and an exam question.
