This is a short activity that uses Google Earth to explore sea-level change as measured by tidal gauges around the world
During this module students use multiple experiences (reading, video,
the outdoors, a survey of their water footprints, writing, and lots of
discussion) to examine how life today, in comparison to pre-industrial
times, makes our connections to water virtually invisible. Students use
the class's water footprint results to find out how agricultural and
industrial water uses link us to people distant in both place and time.
They weigh the consequences of these invisible connections in creating
the lost sense of dependence and responsibility that typifies
unsustainability. Students study the variability of water footprints
within our class to help identify more sustainable personal choices.
They consider the activity of a local watershed association to educate
and involve people in improving the quality of local streams as a model
of how community action can accomplish what individuals cannot.

This activity introduces students to the Arctic and Arctic climate. Through a virtual exploration of the geography of the Arctic students become familiar with the region. They are then introduced to meteorological parameters that Arctic research teams use.
In this activity, students examine global climate model output and consider the potential impact of global warming on tropical cyclone initiation and evolution. As a follow-up, students read two short articles on the connection between hurricanes and global warming and discuss these articles in context of what they have learned from model output.
Once the pride of the German Navy, this 700 foot long heavy cruiser was used by the U.S. as a test target for not one but two atom bombs at Bikini atoll. Today, at the bottom of the ocean, the radiation levels of the Prinz Eugen are low enough for safe exploration. In this video, Jonathan joins historian Mark Miller on a trip to explore this mysterious shipwreck. What they find about the condition of this wreck is surprising. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.
This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing calculator is recommended, but not required, for this activity. This is the second activity in the Solar Storms and You: Exploring the Wind from the Sun educator guide.
Students will observe/investigate the movement of water through the different stages of the water cycle and determine what drives this cycle. Students are asked to think about what precipitation is then watch a video about why the water cycle is important. They observe a simple version of the water cycle and take some notes. Students are asked what stages require solar radiation, which require water to give off heat, and which are driven by the force of gravity. The teacher does several different demonstrations while students fill in a sheet that has the students recording their observations of different processes in the water cycle and how energy is involved. Students build their understanding of the water cycle through the different models that are shown or experienced. The culminating activity has them create their own model of the water cycle from the viewpoint of a water molecule including the processes, the energy involved, and gravity.
In this lesson, students will learn about the water cycle and how energy from the sun and the force of gravity drive this cycle.
In this activity, students work in groups to put a set of cartoon cards in order, much in the way that we might assemble a geologic history. The primary goal of the activity is to explore the nature of science in general and the nature of geoscience or historical science specifically, without requiring any content knowledge.

This activity is designed as both an introduction to GIS and an exploration of topographic steady-state. Students analyze DEMs from Taiwan to extract topographic profiles across the range. They reconstruct a series of datasets presented in Stolar et al., (2007), showing the progression of the range to steady-state as a space-for-time substitution from south to north. Students are expected to relate their observations from the topography to theoretical concepts discussed in class including accretion and uplift, steady-state, and critical wedge theory.
An extension involves developing a simple numerical model in Excel of a mountain range as it progresses to topographic steady-state landscape, allowing students to investigate the rise of a mountain range to steady-state both from Taiwan data and from their numerical model.
Children work together in a group to create an Earth landscape, compare different environments on Earth, and talk about what makes Earth special.
students are engaged in reflecting on whether plate tectonics is a general theory of planetary organization and evolution. Students use topographic, magnetic, spectral, and other data from NASA and ESA missions to determine whether "Earth-style" plate tectonics is functional on planets and moons elsewhere in the solar system. Students are engaged in a data-rich environment from which they must formulate and test multiple hypotheses. Throughout the process, students are engaged in small groups to identify what they need to learn to answer their questions, what resources are available to them, how best to report their findings, and how they can assess the amount of learning that is taking place.
The Extreme Events Game is an in-person role-playing game that allows participants the experience of building community resilience in the face of disaster. Players work together to make decisions and solve problems during a fast-paced disaster simulation.
This short video clip is part of a longer video series titled How Climate Effects Community Health. This clip focuses on human health risks from extreme heat events caused by increasing global temperatures.
In this activity, students investigate how scientists monitor changes in Earth's glaciers, ice caps, and ice sheets. The activity is linked to 2009 PBS Nova program entitled Extreme Ice.
This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.
Research physical scientist, Dr. Dalia Kirschbaum, is featured in this short (~3 min.) video. Dr. Kirschbaum explains how the integration of her initial interest in math and her subsequent interest in the science of natural disasters lead to her career focus of landslide modeling. Now part of the NASA Global Precipitation Measurement (GPM) team, she communicates about the GPM mission and data to the public and to others who use it in their work and/or research.
The first problem in this assignment is the culmination of the unit on energy balance and greenhouse gases. The students have already calculated blackbody temperatures as a function of albedo, sun's luminosity and distance from sun. They have also already calculated the magnitude of the greenhouse effect (optical thickness) of the modern atmosphere. In this first problem, the students apply these same calculations to the Faint Young Sun hypothesis and infer what can account for the geological evidence for liquid water on earth since 4.3 Ga. The second problem follows an introductory lecture on radiometric decay and radiometric dating. The students have seen the decay equation and learned what are decay constants and stable versus radioactive isotopes. In this problem, the students apply these concepts to radiocarbon.

Fairplay, CO Mining Town. Western Mining History presents a brief summary of Colorado's Historical Mining Towns with links to additional Colorado resources for a mining town database and mines by county. Western Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a strong primary source resource that can be used for a variety of class research projects. Consider becoming a member or making a donation to help further the work of the site.
