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.
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.
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.
Motion Concepts: Displacement, velocity, & acceleration graphs part of 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 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 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 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.
The Transformer: Simulation Lecture Demo part of 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 Examples
The activity presents a Think-Pair-Share analysis of a metal detector including a simulation.
