In this problem set, learners will analyze a table of electrical consumption of appliances when not in use and consider the total consumption in kilowatt-hours (kWh), associated cost and their own consumption when appliances are in "instant-on" or... (View More) "stand-by" mode. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change. (View Less)

In this problem set, learners will compare before-and-after satellite images of Greece to answer questions related to biomass loss as a result of the 2007 fires. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth... (View More) Science and Climate Change. (View Less)

This is an activity about solar rotation and sunspot motion. Learners will use a sphere or ball to model the Sun and compare the observed lateral motion of sunspots to their line-of-sight motion. This is Activity 1 of the Space Weather Forecast... (View More) curriculum. (View Less)

In this problem set, learners will calculate energy consumption in kilowatt-hours (kWh) and its associated cost in two scenarios. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

In this activity, learners write space weather reports using current data about the Sun and create a broadcast script to present the researched information to an audience. This activity is part of the Space Weather Action Center Educator's... (View More) Instructional Guide, which follows the 5E learning cycle. (View Less)

This activity, effective outdoors or indoors, demonstrates how insolation is affected by latitude by using a pair of thermometers, each taped to some cardboard, placed outside on a sunny day. A globe can also be used, outdoors or indoors. Students... (View More) learn that seasonal variations in temperature are the result of the heating of the Sun as a function of its peak angle and length of the day. A template for a folded paper structure to explore the effects of the angle of illumination on heating 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.

In a mechanical demonstration of the Pythagorean theorem, this example provides a practical, hands-on method for deriving square roots using a carpenter's square. This resource is from PUMAS - Practical Uses of Math and Science - a collection of...

In this demonstration, evidence of the Earth's rotation is observed. A tripod, swiveling desk chair, fishing line and pendulum bob (e.g., fishing weight or plumb bob) are required for the demonstration. This resource is from PUMAS - Practical Uses...

This activity is designed to help building student understanding of how scientific theories can change over time. Science theories change in the face of new evidence. However, when new explanatory frameworks, or theories, are proposed to explain... (View More) scientific phenomena, there is often a lengthy period during which groups of scientists use different competing theories to explain the same phenomena. During the activity, students are introduced to the geocentric and heliocentric models, students compare the two models, and then observe the time it took to change the theory underpinning the heliocentric model. This activity is part of the "Swift: Eyes through Time" collection that is available on the Teacher's Domain website. (View Less)

This tutorial lays the foundation to participate in the Students' Cloud Observations Online (S'COOL) project. S'COOL engages students in making and reporting ground truth observations of clouds then comparing those observations with data from the... (View More) CERES satellite instrument. Student observations are taken within +/- 15 minutes of the satellite overpass schedule; scientists then use those observations to validate and improve the satellite results. The tutorial covers the following four topics: determining satellite overpass time, observing cloud properties, transmitting results to NASA, and comparing results with satellite-retrieved properties.
