The Sunflower Life-Cycle

The sunflower starts life as a seed. When the seed is planted in the soil, it sprouts roots and shoots up a stem. Soon, leaves grow on the stem. As the plant grows, the stem gets thicker and stronger. The leaves get bigger, too. Soon, a blossom develops and, after some time, will open up to a flower where seeds will grow. When those seeds fall to the soil, the life-cycle will begin again.

El ciclo de vida de un girasol

El ciclo de la vida de un girasol empieza con una semilla. La semilla se planta en la tierra y, despues de unos dias con un poco de agua y sol, crece raices y manda un vástago y hojas arriba de la tierra. Después de unos dias más, el vástago y las hojas se ponen mas fuerte y crecen una flor. La flor se pone más fuerte con agua, sol y el tiempo, y, al final, crece semillas en el médio de la flor. Cuando las semillas se caen, el ciclo de vida empieza otra vez.

The Frog Life-Cycle

The life-cycle of a Frog starts in a fresh water pond. The mother frog lays eggs in a pond and after a few days the eggs hatch into tiny tadpoles. The tadpoles are more like fish than frogs. They have gills and breathe underwater. Eventually, they will grow back legs, front legs and lungs. When they have formed their back legs, front legs and lungs, their tail begins to shrink. They are no froglets. When the tail disappears, they are adult frogs and will live in both land and water.

El ciclo de vida de una rana

El ciclo de vida de una rana empieza con unos huevos que la mamá rana pone en un estanque de agua. Después de unos dias, los huevos nacen en unos renaquajos. Estos renaquajos se parecen más a unos peces que ranas. Después de dos semanas, los renaquajos empiezan crecer las piernas de atras y las piernas de alante. También, empiezan crecer pulmones. La cola se empieza hacer más chiquita. En esta etapa, todavia no es una rana adulta porque tiene un poquito de su cola todavia. Cuando la cola se desaparese completamente, es una rana.

The Butterfly Life-Cycle

The life-cycle of the butterfly starts with a tiny egg laid on a leaf by the mom butterfly. After a few days, the egg hatches and out climbs a caterpillar. The caterpillar eats and eats and sheds its skin as it grows. After a couple of weeks, it makes a chrysalis on a twig or branch and changes for the last time. The caterpillar will stay in the chrysalis for about 2 weeks. When it emerges, it will be a beautiful butterfly.
