In this model eliciting activity (MEA), students are hired by a travel magazine to determine if two airlines that fly into Chicago are equally reliable. They examine data of flight arrival delay times for both airlines flying out of the same city. They first identify measures that can be used to compare the two airlines. Working in small groups, the students decide the size of a meaningful difference between the airlines for each measure and use that information to determine a rule that for deciding if one airline is more reliable than another. The students apply their rule to flight arrival delay data for the two airlines from four additional departure cities, and use the results to write a report to the magazine editor on whether or not one airline is more reliable than the other. This activity can serve as an introduction to ideas of central tendency and variability, and prepares students for formal approaches to comparing groups.

This is an inquiry where students will be comparing and contrasting two different types of leaves with a partner.

Think-pair-share and jig-saw activity asking students to study and compare subsidence curves from different tectonic settings.

The lesson is designed for fourth grade students using scientific investigation to identify and compare the basic parts of a plant and animal cells. This activity consists of several steps over a period of several days. It includes student use of microscopes for observations and journals to collect data to identify and classify the basic parts of plant and animal cells. The assessment has an individual component and uses student work.

This assignment exposes students to data on economic growth and development as commonly measured by per capita GDP and the Human Development Index (HDI) for 100 countries of the world. There is a big debate about how good an indicator HDI is compared to GDP per capita as a measure of development.

This assignment connects aspects of green chemistry and environmental stewardship with some of the skills and theory involved in natural products chemistry and separation methods.

In this exercise, students use whole-rock major- and trace-element compositions of volcanic rocks to explore the origins of compositional variation in igneous suites. Large datasets from the Yellowstone and Crater Lake calderas are downloaded from the GEOROC database, imported into Excel spreadsheets, and graphed to learn about the different petrogeneses of these two volcanic suites.

In this exercise, students use whole-rock major- and trace-element compositions of volcanic rocks to explore the origins of compositional variation in igneous suites. With the help of detailed step-by-step instructions, datasets from the Yellowstone and Crater Lake calderas are downloaded from the GEOROC database, imported into Excel spreadsheets, and graphed in the form of "Harker" diagrams to learn about the different petrogeneses of these two volcanic suites.

The intent is to provide a map-based framework, complete with animations showing the geologic evolution of the area to be visited, so that students can then better appreciate the observations made at the various stops along the way and see how they each relate to the other and the big picture.

Spreadsheets Across the Curriculum module. Students build spreadsheets to find dosages in mL/admin from prescription in mg/day/kg and admins/day; body weight in lbs; and concentration in mg/mL.

Introduction: Understanding market price fluctuations is difficult for the average consumer as they are not often cognizant of what raw materials are used for various products. The goal of this lesson is to illustrate as many of the economic principles related to mineral commodities as possible and, as the lesson is ideally taught in the context of an earth or environmental science course, to couple these principles with the realities of mineral mining and subsequent processes required to produce a raw material from an ore. The lesson uses copper as an analog for such commodities. While the scope of this lesson is, then, quite unusual for high school students, these concepts are quite necessary to produce a populace who can make educated, socially-responsible, and economically-prudent decisions in both their political and personal lives.

Background: This lesson is ideal for any situation where the goal is to teach earth or environmental science students about the realities of mineral commodities, how they are extracted, and how supply and demand for them work to create that market, produce goods, and affect the environment. In the real world, most of the supply-chain for such products is hidden from the end-use consumer. This is certainly not intentional on the part of governments and corporations, necessarily, but is pretty typical due to the remote nature of most mining operations and the lack of contact that consumers have with various mid-level parts of this supply chain. Typically, the only exposure to mineral commodity prices will occur when this consumer wishes to purchase a product that contains those minerals and whose price is observed to not be consistent over time. Petroleum is a common example of this in our everyday lives, but it is no different than any other. Thus, this lesson focuses on the life cycle of copper, which is a mineral commodity that most of us think little about in our day to day lives yet is just as prevalent and important as other commodities like petroleum.

These are interactive lecture-demonstration questions probe student understanding of fundamental concepts in the photoelectric effect.

Conceptests are single item multiple choice questions given in the middle of a lecture to assess students' learning of basic concepts. Because Conceptests are projected during class, it is relatively easy to include snippets of data. Students' understanding of the target concepts can then be assessed based on how well they interpret the data rather than how well they answer verbal questions. The Conceptests on this website use bathymetric data from mid-ocean ridges (MOR's) and test students' understanding of MOR volcanism, plate motion direction, seafloor aging, and sedimentation.
