A simple motor/generator demonstration for use in interactive lecture part of Teaching with Interactive Demonstrations:Examples
This activity describes a simple clear demonstration of electric generators (Faraday's Law) and electric motors (Lorentz Force). This demonstration can be used as an interactive lecture demonstration.
An electrostatics puzzler part of Teaching with Interactive Demonstrations:Examples
An interactive lecture demonstration intended to help students use physics reasoning to predict the outcome of a puzzling electrostatics demonstration.
Contructing a projectile launcher and free falling target part of Teaching with Interactive Demonstrations:Examples
This activity describes the construction and use of a pneumatic cannon and free falling target used to teach the concepts of projectile motion in introductory physics.
Order It Up! part of Interactive Lectures:Examples
A think-pair-share activity which involves putting solar system bodies in order based on various statistics: escape velocity, distance from the sun, mass, etc. -
Pressure Melting of Ice: While-U-Wait part of Teaching with Interactive Demonstrations:Examples
In this demonstration, students get to witness pressure melting and regelation first-hand. A weight is suspended via a thin wire over an ice cube. Over the course of the course of the demonstration, the wire passess through the ice, leaving undamaged ice in its wake.
ConcepTest: Eccentricity and Seasons part of ConcepTests:Examples
Mars has a more eccentric orbit of the Sun than Earth. Mars is 20% closer to the Sun during winter in its Northern hemisphere than it is during its summer. What would be the implications for the seasons on Earth if ...
ConcepTest: Tidal Ranges 2 part of ConcepTests:Examples
If the moon were larger: a. Tidal ranges would be larger b. Tidal ranges would be smaller c. There would no change in tidal ranges.
ConcepTest: Tidal Ranges 1 part of ConcepTests:Examples
If the moon were farther away from the Earth: a. Tidal ranges would be larger b. Tidal ranges would be smaller c. There would no change in tidal ranges
ConcepTest: Axis Tilt part of ConcepTests:Examples
Mars axis is tilted at approximately the same angle as Earth's axis. This should result in a. days of similar length. b. similar sequences of seasons. c. similar temperatures on the planet's surface. d. ...
Activity: Identifying a solid using density part of Measurement and Uncertainty:Examples
Effective measurement techniques include the concept of measurement uncertainty. Students may make erroneous conclusions analyzing data using measurements that do not include the uncertainty of the measurement. In this lab, students determine a density range for a metal and identify the material based on this range.
Lab: Horizontally Launched Projectiles (with uncertainty analysis) part of Measurement and Uncertainty:Examples
This is a version of the time-tested lab where students roll a ball off a table top and use kinematics in two dimensions to try to predict where the ball will land. While many versions of this lab have been ...
Introduction to Measurement (advanced high school/intro college level) part of Measurement and Uncertainty:Examples
30-page illustrated guide to fundamentals of measurement. This is intended to be a clear, comprehensive overview of effective measurement technique. Intended for advanced high school or introductory college level ...
Lab: Measuring the Speed of Sound in Air (with uncertainty analysis) part of Measurement and Uncertainty:Examples
Students use a microphone and Vernier LabQuest to record the sound of a finger-snap echo in a 1-2 meter cardboard tube. Students measure the time for the echo to return to the microphone, and measure the length of ...
Activity: Measure Your Reaction Time part of Measurement and Uncertainty:Examples
This is a lab activity that allows students to collect data to practice using effective measurement. While other authors have produced similar labs, this version includes uncertainty analysis consistent with ...
ConcepTest: Sun Spot Activity part of ConcepTests:Examples
Sun spots, flares and other emissions from the Sun's surface can have a negative impact on electrical systems on Earth. What would be the implications for this type of solar activity if the Sun did not ...
