A deep dive into Brown v. Board of Education of Topeka, a Supreme Court case decided in 1954. It ended the doctrine of "separate but equal" and brought an end to racial segregation in schools. In this video, Kim discusses the case with scholars Michael McConnell and Theodore Shaw.

To manage their businesses successfully, farmers and food production companies need to know what crops are in the ground and how well they are growing. A pair of easy-to-use online mapping tools provides this information for growing seasons in the past and present.

Create a device to blow bubble snakes. Activity from Weekly STEM in a Bag. Colorado Americorp agents in Araphahoe, Denver, Garfield, Larimer, and Weld Counties.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice. Learners will be amazed as the bubbles hover on the denser layer of carbon dioxide gas, then begin to expand and sink before freezing on the dry ice. Use this activity to discuss sublimation, density, and osmosis as well as principles of buoyancy, semipermeability, and interference.

Create giant bubbles! Bubbles are fascinating. What gives them their shape? What makes them break or last? What causes the colors and patterns in the soap film, and why do they change?

Students work in groups to create soap bubbles on a smooth surface, recording their observations from which they formulate theories to explain what they see (color swirls on the bubble surfaces caused by refraction). Then they apply this theory to thin films in general, including porous films used in biosensors, listing factors that could change the color(s) that become visible to the naked eye, and learn how those factors can be manipulated to give information on gene detection. Finally (by experimentation or video), students see what happens when water is dropped onto the surface of a Bragg mirror.

SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

This activity is a lab project where students observe what happens when you try to mix oil and water. It can also be used to work with density.

Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of central tendency of the class data, and then graph and interpret the results.

In this video segment adapted from A Science Odyssey, learn about bubonic plague and how city officials in San Francisco tried to contain its spread in the early 1900s..

Buckskin Joe, CO Mining Town. Western Mining History presents a brief summary of Colorado's Historical Mining Towns with links to additional Colorado resources for a mining town database and mines by county. Western 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 strong primary source resource that can be used for a variety of class research projects. Consider becoming a member or making a donation to help further the work of the site.

This activity is a field investigation where students gather data on physical characteristics of the ecosystem surrounding their school.

Students often come to a principles course in economics with knowledge that is not correct. This example asks students to guess the percent of federal expenditures for different spending categories. They are then shown the actual percentages. The student results can be the source of a class discussion on why many of their initial estimates were wrong (as they generally are). Students can also create their own budget by changing the amounts spent in each category. Budget Explorer, implemented over the internet, uses data from the Public Budget Database of the White House Office of Management and Budget.

Budgeting is the most basic and most important tool in anyone's financial toolbox. With this resource, students are given the hands-on opportunity to create budgets for fictional "Regan" during her sophomore year in nursing school, and, later, as a recent graduate with an apartment and a new car. Using either Microsoft® Excel or Google Docs, the students download our budgeting tool with space for their own budget, as well as the examples they created by establishing Regan's budget.

Museum to the West is a part of the Museums of Western Colorado. Curator of History David Bailey tells us about the Buffalo Bill show coming to Grand Junction. Hear a story about two little boys who may have misspent their money, but still managed to see the big show!

In this Spreadsheets Across the Curriculum module, students build spreadsheets and draw graphs to explore a chemical buffer's ability to resist pH change, i.e., the buffer capacity. Quantification of buffer capacity is conceptually straightforward but involves multiple repetitive calculations. The key relationship is the Henderson-Hasselbalch equation: , which follows from the Law of Mass Action and The spreadsheets automate many of the calculations, thereby simplifying the process. Instead of focusing on the calculations, students can see what buffer capacity means and focus on the a deeper understanding of its implications. After reviewing several buffer calculations, the stduents use the spreadsheet to investigate buffer capacity graphically and characterize blood's physiological buffer system. While solving the question of how many breaths one can take before alkalosis sets in, the students manipulate a logarithmic equation, do "what if" modeling, and analyze rates of change from plots of their cacluated results.

In this activity, students conduct a short hands-on demonstration that simulates ocean acidification resulting from excess atmospheric carbon dioxide and discuss potential implications of increases in ocean temperatures and acidification due to climate change.
