What Worms Do
Worms are much more than just yucky, slimy and wiggly. Worms are earths natural recyclers. Without the help of worms, every plant and animal that died and fell to the ground would stay right where it fell. Trees, leaves, fruit, nuts, dead animals and food would just keep piling up (you'd be living underground like worms!).
In another word, worms are decomposer's. Decomposers break things down into valuable nutrients that can be used by other plants and animals. Start with a old dead log or fallen leaves and you end up with rich soil for new seedlings to grow.

There are fun facts and an interview with Eddie the Earthworm! click here! http://yucky.discovery.com/flash/worm/pg000216.html

In the image below you can observe the worm anatomy; you'll notice the anatomy of a worm has both female and male reproductive organs and several hearts!! <3


Fun Facts!!

  • A worm has no arms, legs or eyes
  • There are approximately 2,700 different kinds of earthworms.
  • Worms live where there is food, moisture, oxygen and a favorable temperature. If they don’t have these things, they go somewhere else.
  • In one acre of land, there can be more than a million earthworms.
  • The largest earthworm ever found was in South Africa and measured 22 feet from its nose to the tip of its tail.
  • Worms tunnel deeply in the soil and bring subsoil closer to the surface mixing it with the topsoil. Slime, a secretion of earthworms, contains nitrogen. Nitrogen is an important nutrient for plants. The sticky slime helps to hold clusters of soil particles together in formations called aggregates.
  • Charles Darwin spent 39 years studying earthworms more than 100 years ago.
  • Worms are cold-blooded animals.
  • Earthworms have the ability to replace or replicate lost segments. This ability varies greatly depending on the species of worm you have, the amount of damage to the worm and where it is cut. It may be easy for a worm to replace a lost tail, but may be very difficult or impossible to replace a lost head if things are not just right.
  • Baby worms are not born. They hatch from cocoons smaller than a grain of rice.
  • The Australian Gippsland Earthworm grows to 12 feet long and can weigh 1-1/2 pounds.
  • Even though worms don’t have eyes, they can sense light, especially at their anterior (front end). They move away from light and will become paralyzed if exposed to light for too long (approximately one hour).
  • If a worm’s skin dries out, it will die.
  • Worms are hermaphrodites. Each worm has both male and female organs. Worms mate by joining their clitella (swollen area near the head of a mature worm) and exchanging sperm. Then each worm forms an egg capsule in its clitellum.
  • Worms can eat their weight each day.

En Espanol!!
Una lombriz puede crecer solamente de largo. El tamaño de una lombriz adulta dependerá de qué tan bien alimentada esté, de la clase de gusano que sea, del número de segmentos que tiene, y de la edad que tiene. Una lombriz terrestre (Lumbricus terrestris) medirá entre 90-300 milímetros de largo.

Un gusano no tiene brazos, piernas u ojos.

Hay aproximadamente 2,700 clases diferentes de lombrices.

Los gusanos viven donde hay comida, humedad, oxígeno y temperatura favorable. Si ellos no tienen estas cosas, ellos se van a otro lugar.

En un acre de tierra, pueden haber más de un millón de lombrices.

La lombriz más larga fue encontrada en Sur África y midió 22 pies de la cabeza hasta la punta de la cola.

Los gusanos cavan muy profundo en la tierra y traen el subsuelo más cerca de la superficie mezclándolo con el suelo de encima. La baba, una secreción de las lombrices, contiene mucho nitrógeno. Nitrógeno es un nutriente importante para las plantas. La baba es pegajosa y ayuda a unir grupos de partículas de tierra en formaciones llamadas agregados.

Charles Darwin pasó 39 años de su vida estudiando lombrices, hace 100 años.

Los gusanos son animales de sangre fría.

Los gusanos pueden crecer una nueva cola, pero si se les corta la cabeza, no pueden crecer una nueva.

Los bebés gusanos no nacen. Ellos son incubados de capullos más pequeños que un grano de arroz.

La lombriz gigante australiana crece hasta 12 pies de largo y puede pesar 1-1/2 libras.

Aunque los gusanos no tienen ojos, ellos pueden sentir la luz, especialmente en su anterior (terminación frontal.) Ellos se retiran de la luz y se quedan paralizados si son expuestos a la luz por un largo tiempo (aproximadamente una hora.)

Si la piel de un gusano se seca, éste morirá.

Los gusanos son hermafroditas. Cada gusano tiene órganos masculinos y femeninos. Los gusanos copulan (se aparean) uniendo sus clitelums (área hinchada cerca de la cabeza de un gusano adulto) e intercambian espermas. Después, cada gusano forma una cápsula para huevos en su clitelum.

Los gusanos pueden comer un tanto de su peso cada día.

Have fun in your own classroom by observing and "messing about" with worms!! Many of these facts can be observed and learned through play and experimentation, making for much more substantial learning and considerable amount of interest.

Not "The End" but "The beginning!!"
