THREAD. Here are some of my favorite #MacGyver hacks - most of them you can easily do yourself. These could also make great projects for kids.
2. For each hack, I will give two scores. Difficulty (D) from 0-10. A 0 difficulty means you already did it and a 10 means you will probably mess up a couple of times.
The other score: Equipment (E) from 0-10. 0 means no equipment 10 is specialized stuff.
3. Make a magnetic compass with a paper clip and a float. D = 2, E = 3.
4. Lift stuff with a lung powered vacuum sucker D = 4, E=3
5. Use carbon dioxide to put out a candle flame (this one is surprisingly cool) D = 2, E = 3
6. Measure acid and base with a red cabbage chemical detector (also quite cool). D = 6, E = 3
7. Send audio signal over a laser D = 7, E = 6 - yes, this one's a little tougher but it's super cool and worth it.
8. Build a speaker. You have to do this one - it's easy and awesome. D = 3, E = 3
9. Arc lamp from two carbon rods and a drill battery. . This one's a little iffy - I would pass on this one unless you feel pretty confident (but it's really neat) D = 8, E = 7
10. Build a Faraday cage to prevent your phone from spying on you (you could also just turn it off) D = 4, E = 2
11. What is resonance and how can you use it? I love this trick - you can pretend like you can control stuff with your mind D = 4, E = 2
THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon
THREAD. For many it is the near the start of the fall semester. Here I will share my teaching and learning posts. Some of these are for faculty and some are for students.
2/ I'll start with posts that just deal with students. My first recommendation - ditch that scientific calculator. It's overpriced and not nearly as good as python wired.com/story/ditch-th…
3/ Three things to learn for physics lab: unit conversion, graphing, and looking past the instructions wired.com/2017/01/wanna-…
