Mikroskopointi+microscopy

Seitsemäsluokkalaiset tarkastelivat planktonnäytettä mikroskoopilla. Kuvat ovat oppilaiden kuvaamia. 7th grade students were studying fresh water plankton. Photos taken by these students.










































== Yhdeksäsluokkalaisten mikroskopointityön aiheena olivat pintakudoksen solut. Posken limakalvon epiteelisolut värjättiin metyleenisinisellä. Kuvat ovat oppilaiden kuvaamia. Miten solu eroaa kasvisoluista ? Cheek epithelial cells were studied by 9th grade students. Photos were taken by 9th grade students. Cells were scraped from the inner lining of cheek. Cells were methylene blue stained. In what way is this cheek cell different from a plant cell shown later below ? ==





































== Metyleenisinisellä värjättyjä sipulin soluja. Suurennos 150 X. Mikroskopoinnin suorittivat kahdekasluokkalaiset. Onion cells in microscope, magnification 150x. Staining agent is methylene blue. Photos taken by 8th grade students. ==

Alla sipulin soluja värjättynä eosiinikeltaisella. Suurennos 150 - 400 X. Kahdeksasluokkalaiset kuvasivat preparaattejaan mikroskoopilla. Next, 8th grade microscopy exercise in which onion cells were stained with eosine yellow. Magnified by 150-400 X. Again, photos taken by students themselves.

Next slides show minor plasmolysis.Cell membrane is partly visible now.

Plasmolyysi punasipulin soluissa. Oppilaiden tekemiä preparaatteja. Plasmolysis in red onion cells. Samples done by 8th graders.

Kahdeksasluokkalaisten kuvaamia tulppaanin ilmarakoja. Tulip stomata were photographed by 8th graders. No dye was used.

** Kahdeksasluokkalaiset etsivät maastosta rahkasammalta, määrittivät sammalen veden imemiskyvyn ja tutkivat mikroskoopilla rahkasammalen solurakennetta. 8th grade students were told to look for sphagnum moss in a coniferous wood, then study its ability to store water and also to take a closer look at the cell structure. Photos below were taken by these students at the lab. **
