In this experiment, students observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere. This process is a part of the carbon cycle and results in temperature suitable for life. Students learn that the carbon cycle is a fundamental Earth process. Throughout Earth's history, the balance of carbon has kept the atmosphere's carbon dioxide (CO2) and Earth's temperature within relatively narrow ranges.

In this media-rich lesson, students explore careers in science through profiles of Alaska Native scientists. They consider how traditional ways of knowing and Western approaches to science can complement each other and allow students to incorporate their own interests when considering careers in science.

This lesson attempts to correct the common misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. Proceeding from student preconceptions, small groups participate in an exploration of the cause of the seasons using a basketball, small globes and a lamp. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This lesson addresses the common student misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. This lesson encourages students to voice this misconception at the beginning of the lesson and then attempts to correct it-first, by exploring the reason for it, and then by presenting an alternate explanation. Materials needed for the demonstration include a small globe and a desk lamp for each group of students, a large ball, and overhead transparency. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Learn about the Chandra X-Ray Observatory's telescope system, science instruments, and spacecraft system in this interactive activity adapted from NASA.
Students are presented with a graph of atmospheric becomes CO² values from …
Students are presented with a graph of atmospheric becomes CO² values from Mauna Loa Observatory, and are asked to explore the data by creating a trend line using the linear equation, and then use the equation to predict future becomes CO² levels. Students are asked to describe qualitatively what they have determined mathematically, and suggest reasons for the patterns they observe in the data. A clue to the reason for the data patterning can be deduced by students by following up this activity with the resource, Seasonal Vegetation Changes. The data graph and a student worksheet is included with this activity. This is an activity from Space Update, a collection of resources and activities provided to teach about Earth and space. Summary background information, data and images supporting the activity are available on the Earth Update data site.

This activity requires construction of a simple salinity tester. Students will create their own calibration scale during this experiment, and look at the change in salinity that would arise if freshwater was suddenly dumped into the ocean. Materials needed for this investigation include a DC mill ampere meter, 2 D-cell batteries and holder, bronze sheeting, #18 solid wire, salt, deionized water, and a stream table or pan apparatus to create a hydrologic model of ice-ocean interaction. Included is a student worksheet to guide interpretation of data. The resource is supported by teacher background information, assessment suggestions, and a scoring rubric. This is Activity 3 of the learning module, Water: Here, There, and Everywhere, part of the lesson series, The Potential Consequences of Climate Variability and Change.

This Changing Planet video documents scientists' concerns regarding how melting Arctic sea ice will increase the amount of fresh water in the Beaufort Gyre, which could spill out into the Atlantic and cause major climate shifts in North America and Western Europe. The video includes interviews with scientists and a look at the basics of how scientists measure salinity in the ocean and how ocean circulation works in the Arctic.
