This activity is a classroom and field activity in which students record observations of birds in their natural habitat and make connections between the structure and function of the bird feet.

In this MS/HS unit supported by NASA, students engage with online interactives, authentic datasets, and citizen science protocols to construct models and explanations for the unit driving question, "How do landscapes recover after a wildfire?"

The GLOBE Cave Protocol Field Guide utilizes existing GLOBE protocols to explore an extreme environment. Caves provide an opportunity to utilize GLOBE protocols to investigate underground environments and compare them to surface environments. Outside the cave, students record elevation, MUC, latitude and longitude, air temperature, relative humidity and air pressure. Inside the cave, students record air temperature, relative humidity and air pressure as well as observe and describe cave features in each room. Students also note evidence of biological activity and human impact. If water is present inside the cave, students record water temperature and pH. Follow up questions are included in the Field Guide.

Focusing on air, water, land and life, this video describes how these components are connected in the Earth system through the flow of energy, cycles of water and biogeochemistry. Methods of studying the Earth system, ranging from field observations to analysis of satellite images are discussed. This video is one of the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.

This video provides a step-by-step guide to determining nitrate and nitrite concentrations in a water sample, using a nitrate testing kit. It describes what chemical reactions are taking place throughout the testing process. The resource includes a video and a written transcript, and is supported by the Nitrate Protocol in the GLOBE Teacher's Guide. This is one of seven videos on hydrology in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment) a worldwide, hands-on, K-12 school-based science education program.

This video highlights students taking scientific measurements to support investigations in atmospheric science, hydrology, soils, and land cover. It shows students reporting data through the Web, creating scientific visualizations for analysis, and collaborating with students and scientists around the world. This is one two introductory videos in the 24-part GLOBE video series. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.

This video demonstrates students measuring the transparency of water, a measure of water quality, using a Secchi disk or turbidity tube. Field measurements of water temperature are also shown. The resource includes a video and a written transcript, and is supported by the Water Transparency and Temperature Protocols in the GLOBE Teacher's Guide.

During a scavenger hunt and an art project, students learn how to use a handheld GPS receiver for personal navigation. Teachers can request assistance from the Institute of Navigation to find nearby members with experience in using GPS and in locating receivers to use.

In this interactive simulation, students can explore global CO2 emissions displayed by different continents/countries and plotted based on the GDP. A map view is also accessible.

This is a multi-media teaching tool to learn about climate change. The tool is comprised of stills, video clips, graphic representations, and explanatory text about climate science. Acclaimed photographer James Balog and his Extreme Ice team put this teaching tool together.

The purpose of the resource is to introduce students to Landsat images and how to identify the land cover types within those images.

This educational video features Sperm whales and has an accompanying lesson plan to teach about Sound in the Sea. The Sperm whale holds many records. It is the deepest-diving whale on Earth, the largest toothed whale on Earth and has the largest brain on the planet too. On top of that, it has a reputation for being a vicious beast, thanks in part to Herman Melville's Moby Dick. But the real Sperm whale is a lot different than people think. It has a highly-evolved social life, operates at depths where nobody can see them most of the time, and uses sonar which is so sophisticated that it makes the Navy's electronics look like toys. Sperm whales are very hard to find and even harder to film. In the Caribbean, Jonathan repeatedly attempts to get close to the elusive whales, until finally he succeeds and has an incredible experience eye to eye with a giant who investigates him with powerful sonar clicks. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This video segment from Outdoor Nevada looks at the Gila monster's behavior, habitat, and unique adaptive characteristics.

In a quiet forest in central Florida, a mysterious pond filled with warm clear water hides a secret at the bottom. In this video, Jonathan explores the pond to find a spring which leads into a cave. As Jonathan travels underground, he meets unexpected marine life in the dark depths and learns how water travels through an aquifer from the underground world to the surface. Please see the accompanying study guide for educational objectives and discussion points.

This short video shows an example of melting alpine glaciers in the Austrian Alps (Goldberg Glacier). Disappearing alpine glaciers have social and environmental impacts, including the decline of fresh water supplies and contributions to sea level rise.

This activity engages learners in examining data pertaining to the disappearing glaciers in Glacier National Park. After calculating percentage change of the number of glaciers from 1850 (150) to 1968 (50) and 2009 (26), students move on to the main glacier-monitoring content of the module--area vs. time data for the Grinnell Glacier, one of 26 glaciers that remain in the park. Using a second-order polynomial (quadratic function) fitted to the data, they extrapolate to estimate when there will be no Grinnell Glacier remaining (illustrating the relevance of the question mark in the title of the module).

Featuring images of glacier formations, this interactive resource adapted from the National Park Service explains what glaciers are, where they are found, how they form, and how they move.

In this activity, students compare two photographs (with time spans of 30-100 years between photos) of specific Alaskan glaciers to observe how glaciers have changed over the time interval. Activity is a good kickoff for learning about glaciology - how and why glaciers form, grow and shrink, and their relation to climate change.

An interactive simulation that allows the user to adjust mountain snowfall and temperature to see the glacier grow and shrink in response.
