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.

This interactive visualization provides a clear, well-documented snapshot of current and projected values of several climate variables for local areas in California. The climate variables include observed and projected temperatures, projected snowpack, areas vulnerable to flooding due to sea level rise, and projected increase in wildfires. The projected values come from expert sources and well-established climate models.

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. Based on the Macorinvertebrate Mayhem from Project Wet.

This activity is a field investigation where students gather and observe macroinvertebrates in a pond system. From their initial observations, students will formulate a question and test procedures.

This inquiry lab is useful for monitoring water pollution in a freshwater system using direct and/or indirect methods.

This video describes why tropical ice cores are important and provide different information than polar ice cores, why getting them now is important (they are disappearing), and how scientists get them. The work of glaciologist Lonnie Thompson is featured, with a focus on his work collecting cores of ice from high mountain glaciers that contain significant data about past climate change.

This is a extensive collection of maps, data, and tools that students can use to research drought and its impacts on agriculture, wildfires, water supply, vegetation, soil moisture, temperature and precipitation.

This activity could be part of a bigger theme under pollution. The activity could be the water part and the bigger focus could contain all other types of pollution.

This is an interactive map of California and the Sierra Nevada mountains, showing how the amount of water stored in the snowpack will vary under different climate scenarios. The tool shows observations and projections from 1950 to 2090, and uses low or high emission scenarios to model future snowpack. The tool can be adjusted to show different months of the year and various climate models, graphed by site.

Spreadsheets Across the Curriculum/Geology of National Parks module. Students use the geometric mean and multiplicative standard deviation to examine the right-skewed distribution of nutrient concentrations in water-quality data at Mammoth Cave National Park.

This activity is a field study where students gather data on a stream based upon their protocol. They will correlate their data with another group and present their results to the class. They will develop and defend in class a new experimental question for a spring study.

This activity is a field investigation where students gather data on stream health by collecting macro-invertebrates at three different locations and then develop an experimental question through land use and topographic map research to explain differences in water quality.

This investigation is a laboratory activity in which the alkalinity of 2 types of substrates (carbonate vs. non-carbonate) are compared on the basis of titration. Students will reflect on the relationship of alkalinity and toxic heavy metals. Teaching ideas from: Project Wet, Water Education for Teachers as found in: "Healthy Water Healthy People, Field Monitoring Guide "(2003)

This is a two part journaling activity prior to an existing week long biology field lab. The journaling activities described here have been added to the beginning of the Pond Study Lab to enhance student learning of observation and quality journaling skills.

This is a real-time map of current drought conditions in the US, which can be zoomed to the state level, with access to many more resources at that level. Some of these include the National Drought Regional Summaries and animations of historical data.

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.

This video features interviews with native people living on atoll islands in Micronesia, so viewers are able to understand the real, current threats that these people are facing due to climate change.

This video takes viewers high into the Rocky Mountain snowpack, where researchers dig snow pits to explore the source of Colorado's water supply. Highlights the importance of snowpack on the supply of fresh water available in western and southwestern states. Snowmelt dynamics are discussed, including the impact of a warming climate.

This is a field investigation in which students test water quality in 2-3 areas using their own testable question.
