Monday 9/28

9/28/15 Monday

 Check in: Friday class & Homework

 Classwork:

  • As long as we’re talking climate change...
    • If someone tells you they don’t believe humans are causing it, you might want to ask them if smoking is bad for you. Why? There is as much evidence that humans are causing global warming as there is evidence that smoking causes cancer (you don’t have to click that link, I just like to put it up).
    • Anyway, here’s a chart:
      • gas_graph1.jpg
      • It is entitled “Breakdown of the anthropic greenhouse gas emissions by gas, in billion tons carbon equivalent, in 2004” - it is a breakdown of the greenhouse gases emitted in 2004 that humans are responsible for.
      • What’s the biggest greenhouse gas?
    • What’s all that CO2 doing, and where does it go?
      • A lot of it goes into the ocean, which seems better than the air, and it is... up to a point. The more CO2 in the ocean, the more acidic it gets (And the more acidic it gets, the lower its ph gets). That is fine... until it’s not. At some point, the acidity will start to kill fish.
      • If we want to see if the ocean is getting more acidic, we need to compare the ph to what?
      • If we want to see if the acidity of the ocean is related to CO2 emissions, what do we put on the chart?
  • That was a downer. We need some animated movies!
    • Which studio made the two highest-profit movies?
    • What were those movies?
    • Before 2004, which studio’s movies always made a bigger profit?
    • What were some of the highest-rated movies (use average rating)?
For homework, fill out the "Understanding Charts" survey for each of these charts (drought, CO2, Pixar/Dreamworks), from the last two classes! one, two, three times, one for each!

Feltron Variables - Monday 2/1/2015

Do you have your tickets... to the gun show? #flexin #doyouevenliftbro Please complete this to show you did your homework: Loading... So, let's talk about what makes this project hard: actually collecting data. It's not hard, but somehow, doing it every day is hard. It's easy to miss a day... then two... then all the sudden, you have missed a bunch, and it's scary and you don't want to think about it, so you don't do it. So we are going to preempt all that by putting some work in today to make it hard to forget. First, we will make a Google form. I started it for you, all you is copy it and add your 4 variables . Once you have that, you are going to use a cool feature of Google Sheets to have google email you this form every day. The form will be in the email itself, so all you have to do is open the email, fill out the form, and hit enter. Here are the instructions to follow . Don't be intimidated! You just have to copy and paste some cod...

Marvin Minsky, AI, Math Education

The audio is too good to make this a gif. So, to be clear, this is the blog post for THURSDAY, 1/28. If you are looking for Tuesday's post, go back a post. I wanted to mention to you all that a mathematician and artificial intelligence researched named Marvin Minsky died on Sunday. Among lots of amazing things he did in his life, he wrote about math education for the OLPC (One Laptop Per Child) project. Here is that article ; I'd like you to read it for homework. Speaking of death, check out this amazing visualization ! Finally, for classwork, I would like you to go back to Tuesday's blog post, and comment on other people's homework. Specifically do you like the charts they chose? Are they interesting? Any feedback? Homework IMPORTANT: Pick which 5 (or more) variables that you will track for the Feltron project. Think about how you will keep track of them - pen and and notebook? The Reporter App? A pedometer? Also, that Marvin Minsky article is really...
