Small groups of students examine a candle to consider its chemical properties. Class discussion follows to consider macro vs. molecular events, energy, phase changes, etc.

In 1887, Robert Towne built a metals smelter two and a half miles northwest of El Paso, Texas, across the river from Ciudad Juarez in Mexico and across the state border from several small towns in New Mexico. The smelter, which processed metal ore from regional mines, was quickly acquired by ASARCO (American Smelting and Refining Company) and became an important visual and economic institution in the region. In 1967, following the mantra of environmental regulation at the time—"the solution to pollution is dilution"—ASARCO erected what was then the tallest smokestack in the world: an 828-foot structure visible from much of the region. While the facility provided jobs to many in the region and produced metals important for a range of manufacturing and consumer products, by the 1970s, residents and scientists began to question the other products from the smelter—especially heavy metals pollution.
This case study includes discussion questions and data sources for further information.

On September 10, 2012, several million southern California residents reacted with alarm to an unfamiliar noxious scent. The Air Quality Management District officials in the Los Angeles region were initially at a loss to determine the odor's source. Investigators from Ventura to Palm Springs looked for toxic spills, sewage plant leaks, and gas line breaks—all for naught.
The smell's origin was the Salton Sea more than 150 miles away and not usually upwind. The smell of an algal bloom and subsequent massive fish kill released odor molecules redolent with the stench of environmental decay.

This case study is an examination of the chemical and sensory impacts of a variety of environmental issues including sand mining, leaking underground gasoline storage tanks (LUSTs), and a railroad.
Wedron is a small, unincorporated town of approximately 100 residents in north central Illinois. A large sand mine has been in operation on the south and west sides of the town for many decades, and the mine property includes several abandoned and active pits, a processing plant, and a train car loading facility. Railroad tracks are located along the east side of town as is a grain elevator (storage and loading facility).
The following information was obtained from the US EPA web site about Wedron, personal visits to the town, and published news articles.

A case-study approach can be used to introduce students to the work that geologists do as environmental consultants. Data used by environmental consultants for a Brownfield site that is currently undergoing redevelopment in St. Paul, MN has been adapted for in-class study, either as a series of short exercises, or as part of a larger project.

By conducting interviews, sharing and assessing data, and writing papers based on their authentic research, students reach their own conclusions on the meaning of the American Dream.
Students identify interesting words from Shakespeare's plays and add them to a classroom vocabulary collection.
Students evaluate coal leases to determine their potential for coal mining. Each company, student group, has three leases and an exploration budget. Students design and implement an exploratory drilling program on each lease and collect partial borehole cores. Using the resultant data, each company creates geologic cross-sections for each lease as well as structural contour maps. Based on their geologic models, they recommend, in oral and written reports, on which, if any, of these leases the company should pursue and how the extractable coal seams might be recovered.

Students and the teacher produce a class book through a group-writing activity, focusing on a basic before-during-after sequence of events.
A checklist to be used by elementary students while they work on group projects to make sure they are using good collaboration behaviors.
A rubric in student language used by elementary students to self-assess their collaboration skills.
Collaborative research project in which undergraduate geoscience curricula at Research 1 institutions are compared. This project uses the methods of science to explore a topic that beginning students can understand. This project uses rubrics for self, peer, and instructor assessment.
Students hone their teamwork skills and play off each other's writing strengths as they participate in prewriting activities for a story to be written collaboratively by the whole class.
Using a collaborative story written by students, the teacher leads a shared-revising activity to help students consider content when revising, with students participating in the marking of text revisions.
This activity consists of classroom lessons where children observe tree leaves and compare and contrast those leaves leading to an understanding of the terms deciduous and evergreen (and also coniferous). They then use that learning to help them identify the kind of tree based on samples on a chart.
This is an inquiry where students will be comparing and contrasting two different types of leaves with a partner.
Do you like teaching, but find yourself frustrated by how little students seem to learn? Would you like to try teaching, but are nervous about whether you will be any good at it? Are you interested in new research on science education? Research in science education shows that the greatest obstacle to student learning is the failure to identify and confront the misconceptions with which the students enter the class or those that they acquire during their studies. This weekly seminar course focuses on developing the participants' ability to uncover and confront student misconceptions and to foster student understanding and retention of key concepts. Participants read primary literature on science education, uncover basic concepts often overlooked when teaching biology, and lead a small weekly discussion session for students currently enrolled in introductory biology classes.
The instructor for this course, Dr. Julia Khodor, is a member of the HHMI Education Group.

After reading "The Tempest" or any other play by William Shakespeare, students work in small groups to plan, compose, and perform a choral reading based on a character or theme.
Successful completion of this cooperative learning activity requires the active involvement of the individual, the small group and the entire classroom (collaboration). The goal is to make a simple task as complicated as possible by constructing a single complex machine.
