Count the Fs: Why a Sample instead of a Census? part of Interactive Lectures: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.

The Transformer: Simulation Lecture Demo part of Interactive Lectures:Examples
The activity presents an interactive lecture demonstration of the operation of a transformer using a simulation.

Think-Pair-Share Analysis of the Operation of a Metal Detector part of Interactive Lectures:Examples
The activity presents a Think-Pair-Share analysis of a metal detector including a simulation.

Work: pre, during and post class questions part of Interactive Lectures:Examples
This series of questions before instruction, in-class peer instruction, and post-instruction allow students to iterate and improve their understanding of work incrementally.

Motion Concepts: Displacement, velocity, & acceleration graphs part of Interactive Lectures:Examples
Students often struggle with motion concepts. These activities focus on the graphical representations of displacement, velocity, and acceleration given a number of situations of an object moving along the x-axis. ...

Measuring voltage and current in a DC circuit part of Interactive Lectures:Examples
These exercises target student misconceptions about how to properly measure voltage and current in simple DC circuits by letting them investigate different meter arrangements without fear of damaging equipment. These activities also are designed to lead to other investigations about simple DC circuits.

Concept Questions for the Photoelectric Effect with Interactive Simulation part of Interactive Lectures:Examples
These are interactive lecture-demonstration questions probe student understanding of fundamental concepts in the photoelectric effect.

Interactive Lecture Questions for Single Slit Diffraction part of Interactive Lectures: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 Interactive Lectures: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.

Projectile and Satellite Orbits part of Interactive Lectures: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.
