This activity allows children to explore the effects of oil spills on birds.
In this introductory-level lab activity, students first view a 20-minute portion of an informative video to learn about the operation of an array of moored buoys that is used to detect changes in the El NiÃo Southern Oscillation (El NiÃo, "normal", and La NiÃa conditions)in the equatorial Pacific Ocean. Students then directly access, display, and work with recent and present data collected from the buoy system using the Tropical Atmosphere Ocean project website. Finally, students examine data from a coral geochemical record to infer past ENSO events.

This teaching activity addresses regional variability as predicted in climate change models for the next century. Using real climatological data from climate models, students will obtain annual predictions for minimum temperature, maximum temperature, precipitation, and solar radiation for Minnesota and California to explore this regional variability. Students import the data into a spreadsheet application and analyze it to interpret regional differences. Finally, students download data for their state and compare them with other states to answer a series of questions about regional differences in climate change.
In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps. By examining scientific visualizations of a data pair in two time slices, they will see that the environment is the result of the interplay among many processes that take place on varying time and spatial scales. This is one of six interrelated learning activities associated with the GLOBE Earth System Poster, Exploring Connections in Year 2007, which also includes a series of assessment and extension activities. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.
In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps. They observe that the environment is the result of the interplay among many processes that take place on varying time and spatial scales, by looking at different six different variables during a single month: insolation, surface temperature, cloud fraction, aerosols, precipitation and biosphere (surface vegetation). This is one of six interrelated learning activities in the student activity guide associated with the GLOBE Earth System Poster, Exploring Connections in Year 2007.

The students will come into this activity with no or very little knowledge of snow. They will divide into groups, each group receiving the first list of questions (on Rite-in-Rain paper). The questions help guide them through their inquiry and are divided into groups: A) initial observations, B) measurement and detailed observations, and C) inferences and hypotheses. They dig a snow pit to the ground (typically < 2ft).
Part A, they study the layered structure, the texture of different layers, the color (presence of sediment?), initially using basic sketching. Then they decide what aspects are worth measuring in further detail (such as thickness of layers, hardness of layer, density of layers, size of crystals) and come up with a plan.
Part B, they are allowed to begin making their measurements and they are given guiding questions, such as what are the errors in these measurements? How many measurements is sufficient to describe the characteristic you are describing?
Part C is primarily brainstorming ideas and hypotheses among their group, and they can return inside if they choose. They are asked consider the role that snow plays on the landscape. How does the snow affect the ground underneath it? Would that role be different at the coldest part of winter than during the spring melt? Does snow affect the air above it? How might snow play a role in the large climate system?
Oral Synthesis: after completing Part C, each group is given a different overarching question, they must use what they have learned and their ideas to give a 4-5 minute oral synthesis to the class.
This activity is meant to give them new insights into a common geologic material and to recognize the linkages between the atmosphere above the ground and the geology and ecosystem below.

How do soils develop over time? Perhaps the best place to learn is a across a chrosequence of deposits that span a wide range in age (and appearance). If we can identify parent material and measure its chemical composition, it can be used as a benchmark for comparison with the chemical composition of soils that were formed from it. This enables us to quantify the degree of chemical depletion. In general we expect older soils to be more depleted, all else equal. But older soils might also be subject to greater physical erosion, in addition to chemical weathering. This complicates the assessment of soil development because the eroded material is no longer present.
Students are presented with two alternate hypotheses about the soils/deposits they visit:
a) the material has been weathering w/ little physical erosion since it was deposited
b) the material has been weathering and eroding since it was deposited
These hypotheses are developed in lectures before the activity and are based on principles of conservation of mass.
During their site visit, students coarsely characterize topography (@2 -- 5 m scale) for several "representative" cross sections. If time is limited this step could be done remotely (e.g., with topo maps and Google earth).
Students assess and discuss evidence for erosional (and depositional) processes since the deposits were created. They look for broad topographic signatures and measure (for example) the spatial density and material volume of tree throw and animal burrowing mounds, if present.
Students also assess and discuss evidence for in-situ weathering (e.g., development of rinds, soil texture, and mineral alteration). The idea is to train their eyes to observe and key in on any site-to-site differences.
Students dig (and discover!) at select sites. They sample soils at regular intervals from pits (with discussion of merits of different sampling approaches e.g., random vs. stratified random). Students discuss relationships in excavated pits.
A jigsaw approach would be an effective way to tackle the large number of field tasks outlined here.
Back in the lab, using literature values, students estimate weathering rates for each deposit. They compare their estimates with back-of-the-envelop estimates for physical erosion rates (based on tree throw/animal burrowing density) and literature values of diffusivity (which can be coupled with curvature measurements).
The instructor promotes discussion of the implications of differences in residence time on weathering rate estimates.
Students analyze samples by XRF; depending on the course's time constraints students are provided with geochemical data from previous year's field effort or other existing data (in this case Taylor and Blum, 1995).
Students are asked to prepare a final report focusing on the following questions: Are soils products of erosion and weathering, or are they being formed in place by weathering alone? Under what circumstances can we expect erosion to dominate over weathering and visa versa? Students first prepare figures and then use them to develop an an outline (reviewed by the instructor) for their report. Students prepare a draft and engage in peer review (one review each). Students revise their reports, based on the peer review comments, and submit their final report.
