Product Overview

  • Designed with our easy cut system - 5 cuts or less. Requires only 3 cuts.
  • Printed on premium thick card stock. May be used unlaminated or laminated

Classified nomenclature for the External Characteristics of Poryphera. Used in the study of zoology in the elementary. This set focuses on just the Poryphera. 

Includes:

  • 1 Wall Chart
  • Control picture and label
  • Control definition and label
  • Matching picture with label, and
  • Matching definition with blanks and label

Since the control charts and control cards are included, we do not include a booklet. 

A small hand reaches into a tide-pool and brushes a purple “plant” that feels like velvet stone.
“That’s an animal called a sponge,” you say. “Scientists place it in the phylum Porifera—a word that means pore-bearer because its body is full of tiny openings called ostia.” In a single sentence, wonder turns into scientific reasoning.

1 • Builds a Precise Scientific Vocabulary

  • Roots that travel wellPorus (pore) + -fer (to carry) gives Porifera; children meet the same -fer in conifer and auriferous gold.

  • Key terms with clear functionsOstia (inflow pores), osculum (exhaust opening), choanocyte (collar cell that drives water), spicule (skeletal spike), mesohyl (jelly filling) all link name to job, reinforcing structure-function thinking.

2 • Sharpens Observation and Classification

  • Body plan over looks – Sponges lack symmetry and organs, yet share a universal water-canal system lined with choanocytes. Guiding children to trace water from ostia → canals → spongocoel → osculum rehearses grouping by internal design, not shape or color.

3 • Grounds Abstract Ideas in Concrete Experience

A dried skeleton reveals spicules under a hand lens; a live freshwater sponge in a jar shows water exiting the osculum as a visible plume. Three-part cards labeling pinacoderm, choanocyte, and spongocoel anchor big words to tangible parts.

4 • Fosters Systems Thinking and Ecology

  • Living filters – A one-kilogram sponge can pump up to 24 000 L of seawater per day, cleansing it of bacteria and plankton.

  • Microbial symbiosis – Up to 50 % of a sponge’s wet mass may be helpful microbes, a gateway to discussing microbiomes and nutrient cycling.

  • Reef architects – Boring sponges recycle calcium carbonate, while reef-building glass sponges create habitat for countless species.

5 • Cultivates Respectful Stewardship

Calling a specimen Aplysina fistularis instead of “sea goo” nurtures care: children gently test water quality rather than break pieces for souvenirs.

6 • Integrates Seamlessly Across the Curriculum


Curriculum Area Practical Tie-In
Language Root study (porus, -fer), sentence diagrams packed with sponge terms.
Mathematics Estimating filtration volume per hour; graphing growth rings on spicules.
Cultural Studies Natural sponges in Mediterranean history; Māori use of sponges for dyes.
Art Radial-symmetry prints of glass-sponge lattices; watercolor washes of canal flow.
Practical Life Testing salinity/pH in a classroom micro-reef; charting osculum flow rates.

7. Prepares for Higher-Order Research

Early mastery of words lets older elementary students navigate primary sources on early animal evolution and biotech uses of sponge compounds.
