March Microscope Madness! (Week 2 - 2015)
Announcer: Frostbite Theater presents... Cold Cuts! No baloney!
Joanna and Steve: Just science!
Joanna: Hi! I'm Joanna!
Steve: And I'm Steve!
Joanna: And this is week two of March Microscope Madness!
We're about to give away the answers from week one so, if you haven't seen that video, you might want to go back and watch it now.
Steve: Okay, so this is your last chance before we spoil it.
Aaaaand, image one!
That is a pencil point. But, we were a little bit sneaky and didn't put the entire point in there, but you can see where the wood's been ripped up by the pencil sharpener and the shiny graphite that was underneath.
Joanna: Image two.
The other end of the pencil, where the eraser and the ferrule meet.
Steve: Image three.
So, you know when you use a pencil eraser and you get all that eraser crud all over the place? Well, this is the eraser crud.
So, to recap: image one, the pencil point; number two, eraser and ferrule, and number three, eraser crud.
If you got all three right, congratulations, but unfortunately, there's no prize involved with this.
Steve: You just get the knowledge knowing that you got all three right, so good for you!
Joanna: So, if you're ready for your next three images, here they are!
Image one, taken at a magnification of thirty five.
Steve: Image two, at one hundred fifty.
Joanna Image three, also taken at a magnification of one hundred fifty.
Okay! Give us your guesses and your suggestions in the comments, and join us again next Monday for your answers and the next three images!
Steve: I would suggest that they write them down, but I guess that's not going to work.
