Video: Middle School Tech Review

Real tools lead to real work at Opportunity Middle School in Concord, NC. Using microscopes, foldscopes, and laser lens hacked cheap fire tablets, our students are opening up their world, all on their own. With only a couple of takes after stumbling over the term “microscope,” these 7th and 8th graders free-styled this video to…

Macro and micro study – Nate’s Flying Insect Project, OMS

(Macro pics with laser pointer lens on iPad camera; micro pics with 140x Foldscope) When I saw this flying insect, we were doing Foldscope.  I was very excited to be doing it and grabbed a yellow (dandelion) flower I saw sitting on the table (from the prior class).  I played with it a little and…

Study in Light: Low/High Magnification, Onion Skin and Natural Light.

  The topography of the onion skin delights me and the colors are so beautiful, including a purple impossible to capture. Under lower light, the cell walls look taller than the cytoplasm, and look to be ragged, not as I expected.  The shapes of the cells are interesting, and some are curved, perhaps bulging from…

In what patterns can a strand of hair go grey? Low/high mag pics

  After struggling to record high mag lens work, I decided that I might be simply misunderstanding what I see through the high mag lens.  Color saturation, light, and pattern are hard to interpret when we are used to our eyes alone or a low mag lens.  Reminds me of the concept someone else shared,…

Low mag success, high mag lens dirty? Help!

Human Hair 140X LED/condenser…successful. I set up the Foldscope with the condenser lens and LED setup, and high mag lens, using a 3 stack of paper slides as supplied. All worked except I couldn’t get a clear focus (lens looked spotty – maybe my inability to focus in/out correctly/or just how a high mag lens…
