In this demonstration, students experience the Doppler effect for sound. Students can compute the frequency change for motion along the line of sight (LOS) and determine the vector LOS component for motions not exactly on it. A buzzer, battery, bicycle wheel, string and a rubber ball and a timer are needed for the demonstration. 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.

The purpose of insulation is to maintain a temperature difference between inside and outside with the least possible heat flow and thus a smaller heating requirement. If it's cold outside and the insulation value of a wall or window is low, the temperature near that surface will be lower, too. Move thermometers around the model building walls -- both inside and outside -- to locate where the insulation is good and where it's not so good.

This activity includes twelve monthly star charts to identify the stars that are visible in the night sky and that are known to have planets around them. The star maps can be used to find constellations and identify stars with extrasolar planets. (Northern Hemisphere only, naked eye)

Students compare budget deficits and surpluses generated between 1969 and 2008 measured in nominal terms and then as a percentage of GDP.

This game has students simulate the propagation of P and S waves after an earthquake and to use the lag between these to determine where in the simulation the earthquake occurred.

In this activity, students learn that the small droplet size of water the in the clouds and wind contribute to clouds remaining suspended in the sky. The demonstration requires a clear beaker, sand, and rocks. Several other activities are suggested. 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.

This is an out of class exercise that allows students to explore biological molecules that contain heme like molecules with metals bound in them. The properties of these molecules give them different colors and functions, but all are related evolutionarily.

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen in the demonstration is 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.

This activity includes a set of slides with embedded images, animations, and interactives that students use to investigate extreme weather events. This is module 8 of a Satellite Meteorology course.

This is a wildfire simulation with three different zones (plains, mountains, and foothills). The user can change variables to see what happens when they spark a fire.

In this discussion paper by colleagues at Harvard University, the future of a large U.S. electric vehicle market is examined based on key questions. To answer these questions, battery electric vehicles (BEVs), plug-in electric vehicles (PHEVs), and internal combustion engine vehicles (ICEVs) are compared with current and projected future lifecycle costs and various scenarios (change in gas/electricity cost, battery cost, customer discount rates, and vehicle efficiency). It is found that currently BEVs and PHEVs are $4000-$5000 more than ICEVs based on lifecycle cost, but in 10-20 years BEVs will be $1000-$7000 cheaper than ICEVs while PHEVs will possible remain more expensive than ICEVs unless battery cost drops significantly and gas prices rise. It is concluded that for the electric vehicle market to increase substantially in the next 10-20 years, gas prices will need to be $4.50 to $5.50 per gallon while battery technology and range increase. However, this can be accelerated with government assistance.

This virtual eco-challenge requires students to learn about the features of topographic maps, ground navigation and land forms. It is a paper exercise that simulates a real outdoor adventure into the Wind River Mountains and must be used with real USGS quadrangles. This exercise can be easily re-framed into your local context. An urban example might be taking a drive to the country (or other local favorite) and having a car breakdown. Then, getting lost and having to navigate the way home.

In this problem-based learning (PBL) scenario, students prepare a presentation for investors showing how their fishing company has a significant advantage because it locates upwelling zones and fishing areas using TRMM (Tropical Rainfall Measuring Mission) and other satellite data. Prior to launching the PBL, students learn about wind: the topics of air pressure, coriolis effect, upwelling and the role of differential heating on the atmosphere are explored in classroom demonstrations. Materials required include a beaker, coffee grounds, drinking straw, balloon, flashlight, and turntable. The resource includes teacher background information, glossary, assessment rubric, and an appendix introducing problem-based learning.

This is a full color, worldwide, animated weather map using GIS interface showing current and projected wind and other weather conditions for any location in the world. Data can be viewed at different spatial scales.

In spring 2020, the world was hit by a pandemic that spread globally by March, causing universities and most of the world to move to remote means. Summer field camps, long hailed as a rite of passage in the geosciences, were cancelled throughout the US. The community moved quickly, with NAGT developing remote learning tools and arranging for sharing and collaboration between instructors and institutions. As such, UNAVCO (GETSI) and University of Northern Colorado embarked on a data collection campaign for a summer field course entitled "Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes" -- originally slated for in-person teaching. The team collected GNSS data, drone imagery for use in structure from motion, and terrestrial laser scanning from a site near Greeley, Colorado on the Poudre River. This assignment follows Sheep Draw SfM and uses an Open Source software, CloudCompare (https://www.danielgm.net/cc/) that allows for viewing and manipulation of point clouds. This exercise will walk you through 1) basic operations and use in CloudCompare, and 2) use of an Open-Source plugin in CloudCompare called CANUPO (http://nicolas.brodu.net/en/recherche/canupo/) that allows for point cloud classification. This unit can be used with any point cloud dataset. An optional activity imports rasters created in CloudCompare and conducts additional analyses in ESRI ArcGIS.

This is a series of NASA Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images taken over a 10 year period, 2000-2010, showing the extent of deforestation in the State of Rondonia in western Brazil over that period of time.

You can create your own lectures, homework, and labs around any PhET simulation by using the PhET Activity Guidelines. These guidelines will help you create "guided inquiry activities which encourage students to construct their own understanding," which are the most effective way to use PhET simulations.
