In My Classroom – #1

Some of us spoke at the KABT Executive Meeting this year about a new segment that I’d like to introduce: In My Classroom. This is a segment that will post about every two weeks from a new member. In 250 words or less, share one thing that you are currently doing in your classroom. That’s it.

The idea is that we all do cool stuff in our rooms, and to some people there have been cool things so long that it feels like they are old news. In this segment, if you are tagged all you need to do is share something you’ve done in your classroom in the last two weeks. It must be recent, but that’s it. If you are tagged, you’ve got two weeks to post your entry. Who knows… your supposedly mundane idea, lesson, or lab might be exactly what someone else really needs. Keep it brief, keep it honest about the time window, and share it out! Here we go:

Last week I built a new method for selecting study plots during field ecology work. The content isn’t close for my students, but I tested the build and sure enough I think I like it.

Twine, wooden dowel, masking tape, and pennies.

Twine, wooden dowel, masking tape, and pennies.

Twine that is 56.4cm long will trace a circle with an area of 1.00m^2. Add 2cm to use to attach the twine to one end of 10cm of dowel, and tape a few pennies a couple centimeters from the other end to weight the dart properly. Now it throws straight and true, with the weight and the twine tail making it a “sampling dart”. Wherever it lands, draw the circle and count your organisms.

It solves the problem of making random(ish) samples in an area, plus it makes it easier for students to measure out 1m^2 study plots.

That’s it for me, so Chris Elniff is on the clock!

  1. Elniff happens to have a new, perfectly functioning KABT account and has been doing some really neat things in his classes! Can’t wait to hear what he posts, and I really enjoyed reading your inaugural post, Michael.
