Magnification Experiments

Science class today was all about learning how Alex's new microscope works.  She gathered some materials on our nature walk to examine.  Turns out I need a refresher in making slides.  We ended up having better luck with some of the pre-made slides (she's drawing a bamboo stem) than the ones we made (we tried dog and human saliva, grass and a butterfly wing).  The important part, though, is that she saw the difference between 4x, 10x and 40x magnification!
