## QR Electromagnetism

Upon returning from Thanksgiving Break, we’ll be starting a study of electromagnetism in my Principles of Technology class. To start with, we’ll be doing a QR Knowledge Hunt.

Electromagnetism Knowledge Hunt Cards

The 15 cards are placed on the walls around random parts of the main hallway. The class is broken into 12 teams of 2 and each team is assigned a starting number. Teams must move through all 15 cards in any order they would like as long as there is no unnecessary “congregating” around any single card.

This particular knowledge hunt requires the students to utilize a QR scanner to “read” the question.

They must scan the QR code and then either use their existing knowledge or research skills to answer the question. The answers are then recorded on a provided answer document, which is submitted for a grade from each team. Only one answer document is needed from each team as long as both team members names are on the answer document.

Here are the questions they are having to answer (in no particular order):

1. In electromagnetism, electric current is measured using which SI unit?
2. In electromagnetism, what does the SI unit of a coulomb measure?
3. In electromagnetism, what does the SI unit of a farad measure?
4. In electromagnetism, what does the SI unit of a tesla measure?
5. In electromagnetism, what does the SI unit of a volt measure?
6. In electromagnetism, what does the SI unit of a watt measure?
7. In electromagnetism, what does the SI unit of an ohm measure?
8. Nikola Tesla is best known for his work on what?
9. The electromagnetic force is one of the 4 forces of nature.
10. What are the names of the poles of a magnet?
11. What electrical charge discovery is Thomas Edison credited with that was the “opposite” of the work of Nikola Tesla?
12. What happens when identical poles of a magnet are placed near each other?
13. What happens when opposite poles of a magnet are placed near each other?
14. Who is credited with the discovery of induction (production of an electromotive force (ie voltage) as a result of the interaction between two magnetic fields)?
15. Who is the French mathematician and physicist, considered to be the father of electrodynamics?

Following the delivery of the exercise, I will be posting an answer key to this exercise.
