Mollusks & Crustaceans

After dissecting the specimens we received on Thursday the children have continued to learn about an invertebrate being a Crustacean or Mollusk.

We used the computer, books and our worksheet to help us classify each animal.

Crustaceans are mostly water-dwelling invertebrates (no spine), characterized by a jointed body and limbs, and a hard outer shell called an exoskeleton.

The name Mollusk means “soft”, because mollusks don’t have any skeletons. Many mollusks have shells made of calcium to protect them.

The children took their time sounding out each word and writing it…

As the children are trying to differentiate between the two they began making a chart that focuses on:

  • Vertebrate
  • Invertebrate
  • Crustacean
  • Mollusk

Some Vertebrates listed: Red Snapper, Shark, Whale, Dolphins, Sea Turtles, and Seals.

Invertebrates:Lobster, Starfish, Sting Ray, Clams, Shrimp, Crab, and Shrimp.

Mollusk: Snail and Octopus

Crustacean:Lobster and Crab.

Please view our chart displayed in the hallway!

Learning Goals Achieved:

  • Children are provided varied opportunities and materials to: collect data, represent and document their findings (through drawing or graphing).
  • Children are provided varied opportunities and materials that help them learn and use scientific terminology and vocabulary associated with the content areas.
  • Each Kindergartner is encouraged to write independently each day.
