Count the Fs: Why a Sample instead of a Census? part of Examples

This interactive lecture activity motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a paragraph. The activity demonstrates that a census, even when it is easy to take, may not give accurate information. Under the time pressure measurement errors are more frequently made in the census rather than in a small sample.

Will the egg break? part of Examples

This is a discrepant event that can be used to help students understand applications of the momentum-impulse theorem. Students are first asked to predict and hypothesize what will happen when an egg is thrown into ...

Modeling emf, Potential Difference, and Internal Resistance part of Examples

Through class discussion and think-pair-share questions, this activity helps students come to understand the difference between emf and potential difference in electrical circuits. These concepts are broached within the context of internal resistance of batteries.

Rutherford's Model of the Atom part of Examples

Students are asked think-pair-share questions to predict the interaction of alpha particles fired toward the nucleus of an atom. An online applet is used to illustrate the interaction and test students' ideas for the causes of the interaction. This activity uses a resource in the comPADRE partner collection.

Interactive Lecture Questions for Single Slit Diffraction part of Examples

This is a set of interactive lecture demonstration questions designed to probe student understanding of single-slit diffraction.

Learning to Think about Gravity II: Aristotle to Einstein part of Examples

The purpose of this exercise is to learn how to think about gravity, learn about scientific methodology, and transition from the Aristotelian to Newtonian to Einsteinian understanding of gravity.

Helping Students Discover Total Internal Reflection part of Examples

Students learn the basic relationship of Snell's Law, practice applying it to a situation, then are given another situation where it "doesn't work."??? This situation turns out to be one in which total internal reflection occurs. Students are then shown what happens with classroom apparatus.

The Evolution of Pearson’s Correlation Coefficient/Exploring Relationships between Two Quantitative Variables part of Examples

The evolution of ideas is often ignored in the teaching of statistics. It is important to show students how definitions and formulas evolve. This activity describes a fairly straightforward activity of how measures of association can evolve.

Models of the Hydrogen Atom part of Examples

In this interactive lecture, models of the hydrogen atom are explored using an online Java applet. The exploration leads to qualitative and quantitative analysis of energy transitions.

Projectile and Satellite Orbits part of Examples

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.
