Science Equipment

Good Will has Celestron LCD digital microscope available.  Note these microscopes are a gamble even if they power on.  Normally my kids use USB digital microscopes with a laptop to view slides.  This means the kids study microscopes at a low resolution.  Most of the time, this is enough.  Once in a while, such as mitosis slides, it’s better to use higher resolution microscopes.  N.B.  When the kids use high resolutions, they are more apt to scratch the lens; the kids forget and use the coarse adjustment and grind the lens into the microscope slide.  See why I use inexpensive digital microscopes?  I am still VERY tempted to bid on the Celestron microscope.  The local library has one for its Maker Space.  The resolution is amazing.  I find the librarians are reluctant to take out the Celestron microscope; they are expensive.  The result is few kids get to experience a good digital microscope.  I cannot rationalize buying one myself; I just want one very badly.
