So I have a real-life problem from our farm and I am wondering how to make it a three act task. (If you are into organic farming you might want to look away…as I just said this is a real-life problem 😉 )
Dan Meyers describes these type of problems as tasks happening in three acts.
Act 1: You introduce the central conflict of your story. (Make it visual…use as few words as possible.)
Act 2: The student looks for resources, asks questions and develops new tools…to overcome the problem.
Notice I said students, but for now I am just going to tell you the tools we have and the question we asked.
TOOLS: 200 gallon tank on a sprayer with a 30 foot span, 19 sprayer heads, each sprayer head disperses treatment at 0.36 gallons per minute, 3 pints of weed killer per acre, and the intention to drive 3.5 miles per hour
Our question: How many pints of weed killer do we need to add to the 200 gallon tank?
Act 3: Resolve the conflict…and set up for a sequel.
My work and Greg’s work
We both got the same answers. YAY!!!! And both used dimensional analysis…I love using dimensional analysis.
So what would be appropriate photos for acts 2 and 3? What about photo 1?
And what would be a sequel?
And actually now that I think about it…it would be interesting to see the questions, resources and tools the more organic minded folks would ask/use.
