This is a ten-question quiz of basic to intermediate information about global climate change.

In this demonstration, a plastic soft drink bottle is used to demonstrate properties of gases and liquids with respect to temperature and pressure. Calculations using the formula for the Ideal Gas Law are included. The 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.

How does water move through Earth's layers? Use the model templates to explore the differing permeabilities of different sediment types, drill wells into model landscapes, explore the difference between confined and unconfined aquifers, discover how water moves around gaining and losing streams, and explore the difference between rural and urban area aquifers. Create your own landscapes to test ideas about water movement and sustainability of wells. Use the graphs to measure the amount of water from each well and monitor the level of water in streams.

This virtual field trip takes students to the site of a local groundwater controversy in Gallatin Valley, Montana. Students virtually travel through seven stops which highlight the groundwater hydrology, local geology, geologic history of the valley and local groundwater policy. During the virtual field trip, students are asked to role-play as geologists hired to evaluate the area. Ultimately, they are asked to formulate an argument for or against the development of a nearby subdivision and to support that argument with evidence they gathered on the virtual field trip. Evidence may include observational field notes, hypotheses and questions regarding the geology and geohydrology of the area as well as limited hydrological data. Students must produce a final report discussing the decision they made as a consulting geologist. Reports should include a well-supported argument using the data and information collected during the virtual field trip. This virtual field trip gives students an opportunity to explore a local dispute regarding groundwater and learn how geology, geohydrology and scientific data are involved in policy issues.

Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.

Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.

After discussing weathering and erosion in class, students are asked to do a small amount of research on different types of chemical weathering, physical weathering, and erosion processes (mostly out of their textbook). Outside of class students then dirty at least four similar dishes with the same type, thickness and aerial extent of food, preferably baked on to ensure maximum stick. One dish is set aside as a control (no weathering or erosion will occur for that dish). For each of the remaining three dishes, students devise an experiment that mimics some sort of chemical weathering, physical weathering, or erosion process (freeze/thaw, sand abrasion, oxidation, etc.). Prior to the experiments, the thickness of food is measured. Experiments are timed, and at the end of the experiment each plate is turned over to determine how much which method removed the greatest aerial extent of food. Experimental results are compared to the control plate to determine the actual effectiveness. Erosion/weathering rates are determined by dividing the thickness of food removed by the experimental time. Students then calculate how long it would take to remove a pile of food the size of the Geology building (assume a 50 m radius sphere), and to remove an amount of food equivalent to the depth of the Grand Canyon. Students then compare these results to rock erosion and weathering rates, performing similar calculations using these "real" rates (see the full project description for details). Photos of each step and the scientists are encouraged in their 2-3 page writeup.

This exercise uses Google Streetview, in combination with 360 degree immersive photographs, to show students real-world examples of the sedimentary rocks, sedimentary structures, and weathering processes that they are learning about in class.
Examples are taken from Parfrey's Glen (WI); Zion National Park; Glacier National Park; Starved Rock State Park (IL); Monument Valley; and Grand Staircase - Escalante National Monument.

If the walls of two houses have different insulation values, you would expect the same heater to have a different effect. Suppose you placed thermometers near the wall of each house, one on the inside and one on the outside. What would you expect the thermometers to show as you heated the houses? Run this model and see if it matches your prediction.

Students will test the percolation rates of 6 different soil samples. Three of the samples are measured sand and clay and three are collected from the schoolyard and wetland.

This demonstration will show how increased temperatures will hasten the melting of ice in the environment, contributing to a rise in sea level and subsequent flooding of coastal areas. Materials required include 2 aquariums, plastic wrap, a clamp light with a 60 watt bulb, modeling clay, ice, pebbles and rocks, and a ruler. Teacher background information, student worksheets and a scoring rubric are included. This is Activity 3 of the learning module, Too Many Blankets, part of the lesson series, The Potential Consequences of Climate Variability and Change.

Through a hands-on examination of a nature preserve/park in a nearby urban setting and with classroom discussions and activities, students become aware that individuals are affected differently by the preservation of nature or by development of natural resources.

Explore pressure at the atomic level. All matter is made up of atoms, which make up molecules. These atoms and molecules are always in motion. When atoms and molecules are contained, we can measure the amount of pressure they exert on the container. This applies to all sorts of pressure: air pressure, blood pressure and tire pressure.

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept.

After predicting which of two earnings streams has the highest currrent value, students use a discounted values table to compare the two earnings streams, discovering that earlier earnings has higher value and that the choice of earnings streams depends on the interest rate chosen.
