Cross Orchards is a part of the Museums of Western Colorado. Curator of Cross Orchards Matt Darling, tells us a bit of the history behind what was once the largest fruit and land company in the valley. He takes us from the 1890s when Walter and Elizabeth Cross began their venture all the way to what Cross Orchards is today. The Red Cross Land and Fruit Company was established in 1899 and operated a massive orchard on the site until 1923. Today it is a living farm museum open to field trips, local events and historical demonstrations. Field trips are welcome.

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.

The output gap is one (of many) economic indicators used by economists to measure the strength of the economy. What exactly is the output gap, and how accurately does it predict the state of the economy? Read the November 2012 issue for an explanation of the output gap and answers to these questions.

Students listen to the story Ox-Cart Man in which a father and his family use various resources to produce goods. As you read the story aloud to the students, place special emphasis on identifying both how it takes resources to make goods and who buys the goods in a market. Students will then participate in a simulation of the circular flow of the economy. They will use examples from the story to apply the concepts learned and model how the circular flow shows the interdependence between people and businesses in the resource and goods/services markets.

The Panic of 1907 was a financial crisis set off by a series of bad banking decisions and a frenzy of withdrawals caused by public distrust of the banking system. J.P. Morgan and other wealthy Wall Street bankers lent their own funds to save the country from a severe financial crisis. But what happens when a single man or small group of men have the power to control the finances of a country? In this lesson, students will learn about the Panic of 1907 and the measures Morgan used to finance and save the major banks and trust companies. Students will also practice close reading to analyze texts from the Pujo hearings, newspapers, and reactionary articles to develop an evidence-based argument about whether or not a money trust—a Morgan-led cartel—existed.

In Part 1 of this unit, students will develop protocols for the collection of sensory data to address a guiding question. The data collected will consist of scents or sounds. The advantage of using sensory data is that students are equipped with the analytical equipment (ears and nose) and are familiar with its use. However, students may not have taken the time to consider the variety of perceptions that occur within a group of people who are sharing a sensory experience and the impact that variation can have when attempting to collect objective data to help characterize environmental problems. Protocols are necessary to ensure consistency of data between collection points and between data collectors, and to link data collected to a research question. Protocols also serve as a record of the methodology used by an investigator that may be subject to scrutiny by subsequent data users or by anyone reading or using a report containing the data. Data collection in all scientific fields may be collected using protocols common within the field or developed by an investigator for use in a specific study. Because sensory data is inherently qualitative and subjective, students will need to develop methods of quantification that ensure as much objectivity as possible. Likewise, scientists collecting field data may need to develop unique protocols that ensure that field data is collected in as objective a manner as possible. Ideally, the unit will span two class sessions to allow for the gradual development of a data collection protocol and field plan.

In Part 2 of this unit, student groups will plan and execute the field collection of sensory data (scents and/or sounds) using previously developed data collection protocols. The advantage of using sensory data is that students are equipped with the analytical equipment (ears and nose) and are familiar with its use. Class time will be devoted to developing a field investigation plan. Students will create guiding questions and choose a study area, develop or obtain maps of the study area, assign field roles to group members, and develop a timeline for completion of fieldwork. The plan will need to ensure proper execution of data collection protocol, a clear record of the data collected, and a record of field conditions. Careful planning of fieldwork is important to ensure that the time in the field is utilized efficiently and effectively and that the data collected meets the intended requirements. Likewise, an environmental professional (such as a geoscientist) undertaking an environmental investigation would need to develop a field investigation plan to meet the needs of the investigation.
