Forces at a Distance: Vernier Supplement to OpenSciEd Unit 8.3

$0.00

In this unit, students analyze a slow-motion video of a speaker as it plays music to investigate the cause of a speaker’s vibration in addition to the effect. Students dissect speakers to explore the inner workings, and engineer homemade cup speakers to manipulate the parts of the speaker. They identify that most speakers have the same parts—a magnet, a coil of wire, and a membrane. Students investigate each of these parts to figure out how they work together in the speaker system.

The Vernier Supplement to Unit 8.3 is a complement to the OpenSciEd curriculum and includes data-collection technology enhanced lessons to supplement the existing curriculum.

Lessons

There are 12 lessons in the full OpenSciEd Unit 8.3

3 of the lessons are enhanced with Vernier data-collection technology and are included in the Vernier supplement. These 3 lessons use Vernier Graphical Analysis™ and the OpenSciEd Sensor Cart Package (one package per two student groups).

Lessons Sensors Used
Lesson 1: What causes a speaker to vibrate?
Lesson 2: What can a magnet pull or push without touching?
Lesson 3: How does energy transfer between things that are not touching?
Lesson 4: What can we figure out about the invisible space around a magnet?
Lesson 5: How does the magnetic field change when we add another magnet to the system?
Lesson 6: How can we use magnetic fields to explain interactions at a distance between the magnet and the coil?
Lesson 7:  How does changing the distance between two magnets affect the amount of energy transferred out of the field? OpenSciEd Sensor Cart Package
(one package per two student groups)
Lesson 8: How does the energy transferred from a battery to a wire coil compare to the energy transferred from a computer to a speaker?
Lesson 9: How do the magnet and the electromagnet work together to move the speaker?
Lesson 10: How does distance affect the strength of force pairs in a magnetic field? OpenSciEd Sensor Cart Package
(one package per two student groups)
Lesson 11: What else determines the strength of the force pairs between two magnets in a magnetic field? OpenSciEd Sensor Cart Package
(one package per two student groups)
Lesson 12: What cause-effect relationships explain how magnetic forces at a distance make things work?
