Biology Lab Ages 16-18 Intermediate

NEB Biology Practicals — Class 11

Class 11 Biology now has its own full practical course instead of being mixed with Class 12. It covers the listed botany and zoology practical activities: microscopy, mitosis, herbarium work, mushroom and flowering-plant study, microbiology culture, quadrat/ecosystem/soil analysis, microscope parts, fossils, animal specimens, alimentary canal dissection and conservation planning.

You will learn: doneMicroscopy and temporary/permanent slide observation doneSpecimen identification with diagnostic reasons doneQuadrat, soil and ecosystem measurements doneGuided 3D dissection and morphology study donePractical notebook readings, tables and conclusions
