Lawn Photos!

Oh, man, awesome. You would’ve found these installations at [redacted] last week.

If I taught science, I’d toss this photo on the wall during one particular unit and let ’em fight over the method. Any readers know how this thing happened? I’ll toss the answer into the comments if y’all founder too long.

[Hint: the answer does not involve a really really tiny lawnmower.]

BTW: a month into summer and I’m totally off my game. Lemme just say that these lawns sculptures involve photosynthesis in kind of a crucial way.

I'm Dan and this is my blog. I'm a former high school math teacher and current head of teaching at Desmos. He / him. More here.


  1. Sorry…. it’s seeming sort of obscure. I can’t quite tell what you’re getting at? Looks like three green-tinted photos of faculty/staff at some school event.

  2. Now, based on the face that these photos appear to be positive images, the lighter areas must have been the grass that had the most stunted growth, whereas the dark areas grew the best/most. So I’d guess that they must have used a negative in the darkroom to mask the growing grass….

    What if you could do this to a Chia pet?!!!!

  3. I love it! This is just what I’m looking for…thanks for helping bring your ideas into the science world. This will be great for our plant unit! Cara S.
