This video segment adapted from NASA's Goddard Space Flight Center describes El Niño, how it forms, and the chain reaction of consequences it triggers around the globe.

This video segment adapted from NASA's Goddard Space Flight Center explains how hurricanes develop and why there are fewer hurricanes in the Atlantic Ocean in strong El Niño years.

This interactive activity from the Adler Planetarium explains the reasons for the seasons. Featured is a game in which Earth must be properly placed in its orbit in order to send Max, the host, to different parts of the world during particular seasons.

Learn about the different features of snow and ice in Antarctica using satellite imagery in this video segment adapted from NASA.

The ecological autobiography is a multi-stage reflective and written exercise that draws on students' personal history and experiences as they consider the ecological context of some period of their lives. The goal is to individually and collectively explore how the landscapes and ecological communities we have inhabited influence us as individuals, set the context of our lives, and influence our expectations of landscape.

This integrated 3rd grade unit addresses the NGSS Life Science bundles for Interdependent Relationships in Ecosystems (3-LS2-1, 3-LS4-3, and 3-LS4-4) and Inheritance and Variation of Traits: Life Cycles and Traits (3-LS1-1, 3-LS3-1, 3-LS3-2, and 3-LS4-2). Students embark on a mission to protect their native plants and animals by devising a plan to regulate and prevent the spread of invasive species in the area. Through a series of FOSS investigations and other OER (open educational
resource) lessons and activities, students learn about how an organism’s traits aid in survival, how parents pass on traits to their offspring, and how the environment influences plant and animal traits and behaviors.

Students will explore and create a healthy ecosystem, once established they will then introduce additional variables which may harm the ecosystem and determine which hazards should be avoided.

This activity is a field trip investigation where students gather stream flow, volume, depth & height (area) data on Ramsey County dams (Keller and Round lake), interpret their findings and make in-depth observations in order to assess the effectiveness of dams through the season and estimate the life-span of the dams in years.

In this video produced by ThinkTV, explore the effects of land masses on local climate conditions, and learn about regional impacts of land-atmosphere interactions.

In this video segment adapted from NOVA scienceNOW, scientists examine the link between rising sea surface temperature and more intense hurricanes.

In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.

The following six figures represent electron transport chains functioning within the processes of nitrification and denitrification within the nitrogen cycle, and methanogenesis within the carbon cycle. Each figure is included with and without a legend. Figure 1 represents oxidation of ammonia to nitrite, the first phase of nitrification. Figure 2 represents oxidation of nitrite to nitrate, the second phase of nitrification. Figure 3 represents reduction of nitrate to molecular nitrogen through denitrification. Figure 4 represents oxidation of ammonia to nitrous oxide by ammonia-oxidizing bacteria. Figure 5 represents reduction of nitrate to nitrous oxide by incomplete denitrification. Figure 6 represents reduction of carbon dioxide by hydrogen gas to produce methane.

Each student will keep a science journal during each of the four seasons. Students will record observations of the general outdoor environment they visit and then will make observations of one specific item from the habitat in each season. At the end of the school year, students will make comparisons of their seasonal drawings and share the results with the class. The purpose of the activity is to introduce students to the concept of using a science journal to record information, to have students use science tools to make scientific observations and to make observational drawings in nature and compare the results throughout the seasons. After completing this activity, students will know about seasonal changes in a particular habitat. They will learn how to make detailed observations, record their results, make comparisons, and share information using a standard format.

A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Each student will be given the opportunity to create their own cumulus cloud out of white paper and mount it on blue paper. Students will also complete the Cloud Fun Student Activity Sheet that includes a description of the cloud and what the weather was like on the day the cloud was observed. The purpose of the activity is to help students identify cumulus clouds and observe the weather conditions on days that they see cumulus clouds. Students will learn about a cumulus cloud's shape and appearance, how to verbally describe cumulus clouds, and what the weather is generally like when these clouds appear in the sky.

A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Using information from the book and their observations, students construct a sky scene with trees and buildings as reference points on the ground and cloud types ordered by altitude in the sky. Students will describe clouds using their own vocabulary and will then correlate their descriptions with the standard classifications of cloud types used by the GLOBE Program. The purpose of the activity is to help students identify some of the characteristics of clouds and to enable students to observe clouds, describe them in a common vocabulary, and compare their descriptions with the official cloud names. Students will be able to identify cloud types using standard cloud classification names. They will know that the names used for the clouds are based on three factors: their shapes, the altitude at which they occur, and whether they are producing precipitation.

The class will brainstorm, write, create, and produce a play in which they represent how all the Earth systems are interconnected. This play can be based on the Elementary GLOBE book "All About Earth: Our World on Stage" or on other student-generated topics representing interconnections of the Earth systems. The purpose of the play is to serve as a performance assessment providing students with the opportunity to display what they have learned about the Earth as a system in a creative manner. Through this activity, students will demonstrate their knowledge of how the hydrosphere, atmosphere, geosphere and biosphere interact.

A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. In pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class and discuss how water, Earth materials, and air are all necessary to support living things. The purpose of the activity is to acquaint students with the hydrosphere, geosphere, atmosphere, and biosphere more closely, to have students use microcosms to study natural phenomena, and to introduce students to the concept of a "fair test" in a scientific investigation. After completing this activity, students will know about the importance of the hydrosphere, geosphere, and atmosphere in supporting the biosphere. They will learn how to set up "fair test", record detailed observations, use drawings as scientific records, make sense of experimental results, and share them publicly.
