These snowflakes aren’t actually from the blizzard. I’m planning on capturing a few more when I go home today. I tried to capture some during the blizzard but my sliding door was frozen shut (and it was too much of a hassle to carry my supplies down the hall and out the front door).
I took a few images of the snowflakes I captured with the digiscope (a digital microscope that plugs into the USB port of a computer). We gave digiscopes to each of the K-12 Teachers that attended one of our NANO Summer Institutes.
I took these snowflakes to Northridge MS with me last week and the students had a chance to look at them with the digiscope.
I also took an image of my blue jeans.
and a lego.
We use the digiscope as part of NANOweek. We talk about optics and magnifying images using light, and then we talk about how the SEM uses a beam of electrons to “see” objects. We then move into how the AFM and STM “feel” the surface and send data to a computer. The computer then assigns a color to each of the data points and creates an image of the topography of the surface.
