What Do You Know Now? part of Cutting Edge:Metacognition:Activities

An opportunity to offer metacognitive teaching arises from the simple question "what do you know now that you didn't before (whatever)"? This simple question can be asked after a reading, a lecture, a lab or other unit of student activity. The thrust is to force the student to consider what they've been exposed to and reflect on what they've learned. Did the activity change their opinion? Did this activity help them identify an analogy?

Challenging Pre-Conceptions part of Cutting Edge:Metacognition:Activities

Students carry into class pre-conceptions based on stories they've heard, articles they've read and experiences they've had. One of the best opportunities to teach metacognition is at a 'gotcha' moment when they come to realize their pre-conception is amiss.

Using Your Marbles: Making Energy Work for You part of Earth and Space Science:Summer 2010:Activities

potential energy, kinetic energy, work

Work: pre, during and post class questions part of comPADRE Pedagogic Library: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. -

Projectile and Satellite Orbits part of comPADRE Pedagogic Library: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. -

Science on a Skateboard - Applications of Newton's Third Law part of comPADRE Pedagogic Library:Interactive Lectures:Examples

A think, pair, share activity with Socratic questioning to help students begin to understand rocket propulsion. -

Will the egg break? part of comPADRE Pedagogic Library:Interactive Lectures: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 comPADRE Pedagogic Library:Interactive Lectures: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 ...

Models of the Hydrogen Atom part of comPADRE Pedagogic Library:Interactive Lectures: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 comPADRE Pedagogic Library:Interactive Lectures: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 ...

Properties of Electrostatic Charge: Interactive Lecture Demonstration part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

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.

The Magic of Optics: Now you see it, now you don't part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

A magical demonstration where a Pyrex tube vanishes in a beaker of mineral oil. Useful demonstration to introduce to concept of refraction (and/or partial reflection).

Introduction to Torques: A Question of Balance, Featuring the Sledge Hammer of the Sierra Madre part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

Interactive Lecture Demonstrations to illustrate the nature of torques and on the balancing of torques in static equilibrium.

Elastic and Inelastic Collisions: The Case of the Happy and Sad Balls part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

Interactive Lecture Demonstration to illustrate that impulses are larger in elastic collisions than in inelastic collisions if other factors are the same.

Experiment Problem in Kinematics: How Much Does it Take to Win the Race? part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

In this activity, students are presented with two objects that have different constant speeds and that will race each other. The students must determine which object will win the race, as well as either how much time elapses between the objects crossing the finish line.

Introduction to Work and Energy: The Hopper Popper Surprise part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

Understanding the Motion of a Harmonic Oscillator part of comPADRE Pedagogic Library:Teaching with Interactive Demonstrations:Examples

This inteactive lecture and series of demonstrations develops the concepts and vocabulary of oscillatory motion as it relates to the motion of a mass on a spring.

The Standard Model: Using CERN output graphics to identify elementary particles part of comPADRE Pedagogic Library:Just in Time Teaching:Examples

After using the historical development of the Standard Model to develop introductory understanding, students link to OPAL and DELPHI data archives from CERN to identify and study the tracks from elementary particles.

Angular Momentum Experiment part of comPADRE Pedagogic Library:Just in Time Teaching:Examples

After using the historical development of concepts of conserved motion to develop introductory understanding, students are directed to a series of activities to gain a better understanding of momentum, conservation of momenta, angular momentum, and conservation of angular momenta.
