This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
Learners listen to a lecture given during the early days of nanotechnology titled, “There’s Plenty of Room at the Bottom.” Dr. Richard Feynman made the presentation to the American Physical Society on December 29, 1959. Animation makes this lecture fun to absorb.
Students use a map of Chicago to find their way to the Museum of Science and Industry. The activity offers practice in identifying directions on a map. A quiz completes the activity.
Learners play a game to review concepts connected with student assessment. The categories on the game board are "General Assessment," "Science Assessment," "Math Assessment," and "Famous Scientists."
Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.
