An interactive lecture segment utilizing videos from the Antiques Roadshow, designed to create an interactive experience for students and the instructor. After watching an expert appraisal of a rare/unique object students respond to discussion questions. Instructors lead the discussion toward issues of subjective value, willingness to pay, and the price mechanism.

Students survey class members to estimate the price elasticity of demand for a number of goods and services.

Students gesture the orientations of cross-bedded sandstones, and in particular the relationship between a single cross bed and the bed sets. They do this for photos of undeformed and deformed cross-bedding.

In principles of economics students many times have trouble understanding the concept of opportunity cost, connecting opportunity cost to comparative advantage, and differentiating between absolute advantage and comparative advantage. This activity allows the instructor to detect whether a large number of students exhibit any of these misconceptions, and then focus on the most problematic concepts in class.

The pro-con-caveat activity is a quick and easy way to engage students through a more interactive lecture experience.

The Processing Integrity Challenge makes use of game theory to help students learn how to determine relevant application controls for accounting systems to ensure processing integrity is achieved. It specifically addresses source data, data entry, processing, and output controls. The playing format is an adaptation of the television game show, Jeopardy, which is a novel way to reinforce concepts and provide immediate feedback to confirm students' knowledge.

This activity is a mini lab where students see the effects of gravity on objects falling from a resting state and objects projected out from the same level.

Gravitation introductory activity with interesting animation. The activity allows the student to revile the connection between the initial speed and the shape of satellite orbit.

In this lab students will make qualitative observations of flame color, a property of metals, to identify unknown metals in salt compounds.

This activity is an interactive lecture demonstration format which can be used to teach the first lesson of electrostatics. Students will investigate conservation of charge, charge by contact, polarization of charge and charge by induction.

In this activity students explore the evolution of proteins by comparing 2D and 3D alignments of orthologs and paralogs.

In this physics activity, students will review and investigate stability of the nucleus of various elements. They will then determine factors that affect the stability of the nucleus.

In this experiment, students must decide how to divide their "endowment" of a good between private consumption and a public good. The private consumption provides a benefit (earnings) to only the individual and the public good provides a benefit to each person in the group, even those who do not contribute to the public good. This hand-run experiment is suitable for use in small classes in the range of 5 to 40 students. Some variations on this basic experiment are also described.

Secondary Math Ed majors or Geometry students are directed to a Web site where they read through a rich and extensive collection of proofs of the Pythagorean Theorem, some accompanied by Java applets. Each student then selects two proofs to prepare to present to the class-a geometric proof and a visual proof-and writes a detailed outline of each proof. The student also indicates one additional proof that was of particular interest and the reason(s) for its selection.

This is an guided inquiry lab activity in which the student will design and carry out a qualitative analysis scheme for the separation and identification of metal cations from an unknown sample.

This assignment is designed to introduce quantitative reasoning and critical thinking in viewing documentary videos on the issues of development. Students will write a review essay about one of three designated documentaries for the course.

Students will read an academic article critically and write a review of the article.

This is an outline for how one could incorporate quantum mechanics into atomic structure. Students really seem to get hooked on it and it makes atomic structure way more interesting to teach.
