This is an online crossword about the Big Keck telescope. Learners can complete the crossword and read text about how the telescope works.

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.

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.

This activity is related to the discovery of water ice on Mars. Learners are provided with a global map showing where the presumed water ice is located and use it as context for analyzing and interpreting images taken with the Thermal Emission... (View More) Imaging System (THEMIS) aboard the Mars Odyssey spacecraft. They will use the water ice maps to interpret the geology of the regions on Mars and evaluate the prospects for exploring these regions in the future. A teacher guide and a student guide are available. This is an extension of the "Mars Image Analysis Activity" and is activity 5 of 5 in Buried Water Ice on Mars. (View Less)

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...
