Experiment set BIOLOGY 1: MICROSCOPY
The problem
Pupils are confronted with three difficulties when looking through a microscope for the first time: the reduced field of view, the upside-down image and their inability to judge the degree of magnification. The MEKRUPHY MICROSCOPY experiment set allows them to gradually master these challenges.
By starting with simple magnifying glasses and moving on to cup and two-way magnifying jars, all of which give a normal image of the object being observed, the children learn to get accustomed to the reduced field of view and can get a feel for the respective degree of magnification, especially when using the 5-millimetre scale.
Durable microscopy tools, special slides and a pair of petri dishes make microscopy easier for them.
The simple-to-use microtome, together with the special razor blade and microscopy brush, make it quick and simple for the older pupils to prepare samples.
