A Day Without Agriculture. This is the Lesson 1 Exposure Activity, from Unit 1 Introduction to Agriculture, from the DIGS (Developing Individuals, Growing Stewards) AmeriCorps Curriculum from CSU. The curriculum focuses on introducing students in grades 3-5 to Colorado agriculture, industry and environmental issues. The curriculum is matched to State Standards 2021. The curriculum upon request. Visit: https://engagement.colostate.edu/programs-old/developing-individuals-growing-stewards/

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. 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 great database for student historical research or data and statistics classes. Consider becoming a member or making a donation to help further the work of the site.

Movement of ions in and out of cells is crucial to maintaining homeostasis within the body and ensuring that biological functions run properly. The natural movement of molecules due to collisions is called diffusion. Several factors affect diffusion rate: concentration, surface area, and molecular pumps. This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models.

For most of human history, recording a star meant describing it with words or drawing a picture. The 19th-century invention of photography changed that—only to be revolutionized by digital imaging. This Moveable Museum article, available as a six-page printable PDF file, takes a look at the technology of digital imaging. It discusses how digital images are pictures stored as numbers and explains how computer manipulation can enhance images and reduce distortion. Some suggested resources are provided for further research.

This contribution is modified from a published exercise "Directed Discovery of Crystal Structures Using Ball-and-Stick Models" [Mogk, 1997] . While the published exercise is based on student exploration of traditional ball-and-stick models of crystal structures, this modified version uses a similar "discovery-based" approach to teach the spatial relationships and crystal-chemical rules that govern the crystal structures of common minerals and crystalline solids, but instead uses the latest web-based crystallographic information and visualization programs. A few changes in the content have been made from the published exercise, mainly to accomodate the new digital media.
