What to Focus On

  • Zoological museum stores preserved animals, skeletons, fossils, models, and charts.
  • Wet preservation uses 10% formalin in sealed jars.
  • Dry preservation includes shells, skins, feathers, and nests.

  • Charts show morphology, life cycles, and taxonomy.
  • Models provide 3D understanding of biological structures.
  • Photographs help connect theory with real organisms.

  • Botanical gardens grow and classify plants for study.
  • Plants are labeled with scientific and common names.
  • Catalogs with collection numbers and descriptions are maintained.

Common Mistakes to Avoid

Formalin is used only to preserve large animals, not small ones or invertebrates.

All dried specimens in museums are natural remains like bones or shells found directly in nature.

Herbarium sheets are made by simply gluing fresh plants onto paper and letting them dry.
