Yes, 140x. I don’t think that we could get a more powerful magnification than this. My students think that is the dust mites because these animals are so small, leave on the leaf and look like mites. Maybe they could be insects, too, but it is hard to say. They use an internet and books [...]

We looked leaf under a microscope and saw dust mites.
We took a leaf from a plant in our classroom and lacquier it with transparent varnish. We waited for it to dry and then we removed a part of the dried paint (lacquier) and put it under the microscope. We found the stomates and took picture of them.
