  1. Life within the Pond Life Cycle of a Frog Life Cycle of a Dragonfly Life Cycle of an Egret Life Cycle of Carp Life Cycle of Plants in a Pond

  2. Life Cycle of a Frog Did a frog always look like this? What is your hypothesis?

  3. 4 stages • A frog goes through many changes during its lifecycle. • Changes are called metamorphosis. Stage 1: Egg Stage 2: Tadpole Stage 3: Young Frog or Froglet Stage 4: Adult Frog

  4. Stage 1 - Egg • The first stage in the life cycle of the frog is the egg. • A frog lays many eggs at one time. • The eggs are covered with a jellylike coating.

  5. Stage 1 - Egg Time to record! Draw what the egg looks like on your flow map. Write one important thing about the egg.

  6. Stage 2 - Tadpole • The second stage of the frog life cycle is the tadpole. • Hatched tadpoles have gills for breathing in the water. • They have a tail, but no legs. • As a tadpole grows, lungs begin to form.

  7. Stage 2 - Tadpole Time to record! • Draw what the tadpole looks like on your flow map. • Write one important thing about the tadpole.

  8. Stage 3 – Young Frog or Froglet • As a tadpole grows, lungs begin to form. • Back and front legs begin to grow. These parts allow the adult frog to live on land.

  9. Stage 3 - Froglet Time to record! • Draw what the froglet looks like on your flow map. • Write one important thing about the froglet.

  10. Stage 4 – Adult Frog • Once the lungs form and begin to work, the gills and tail disappear. • The adult frog is now ready to live on land.

  11. The cycle begins all over again!

  12. Stage 4 – Adult Frog Time to record! • Draw what the frog looks like on your flow map. • Write one important thing about the frog.

  13. Can you tell which stage is which? Young Frog or Froglet Adult Frog

  14. Discussion • Was your hypothesis correct? • How is each stage in the life of a frog different? • Are there any similarities?

  15. Life Cycle of a Dragonfly Did a dragonfly always look like this? What is your hypothesis?

  16. Stages • A dragonfly goes through many changes during its lifecycle. • Changes are called metamorphosis. Stage 1: Egg Stage 2: Nymph Stage 3: Larva Stage 4: Adult

  17. Stage 1 - Egg • Female dragonflies lay their eggs near or in the water.

  18. Stage 1 - Egg Time to record! Draw what the egg looks like on your flow map. Write one important thing about the egg.

  19. Stage 2 - Nymph • The dragonfly becomes a nymph. • It spends most of it’s life underwater. • It eats tadpoles, small fish when it’s underwater.

  20. Stage 2 - Nymph Time to record! Draw what the nymph looks like on your flow map. Write one important thing about the nymph.

  21. Stage 3 - Larva • A dragonfly may spend up to 5 years in the larva stage. • They leave the water in this stage and live on plants.

  22. Stage 3 - Larva Time to record! Draw what the larva looks like on your flow map. Write one important thing about the larva.

  23. Stage 4 – Adult • The larva is ready to metamorphose (change) into an adult dragonfly. • It climbs up a plant at night and the skin splits in weak spots behind the head. • The adult dragonfly leaves it’s old skin behind. • Now it can fly!

  24. Stage 4 - Adult Time to record! Draw what the adult looks like on your flow map. Write one important thing about the adult.

  25. Discussion • Was your hypothesis correct? • How is each stage in the life of a dragonfly different? • Are there any similarities to other animals?

  26. Life Cycle of an Egret Did an egret always look like this? What is your hypothesis?

  27. 3 stages • An egret goes through many changes during its lifecycle. • Changes are called metamorphosis. Stage 1: Egg Stage 2: Chick Stage 3: Adult

  28. Stage 2 - Egg • The first stage of the life cycle of an egret is an egg. • The male egret makes a nest near the pond and chooses a mate. Then the female egret lays 3 to 5 eggs. • The eggs incubate for 3 to 4 weeks.

  29. Stage 1 - Egg Time to record! Draw what the egg looks like on your flow map. Write one important thing about the egg.

  30. Stage 2 - Chick • A chick emerges from her egg after 3 to 4 weeks. • The father and mother egret both take turns feeding the chicks. • The chicks will stay in the nest or near the parents for 6 weeks.

  31. Stage 2 - Chick Time to record! Draw what the chick looks like on your flow map. Write one important thing about the chick.

  32. Stage 3 - Adult • The adult egret will eat alone in shallow water. • It hunts frogs, snails, snakes, and fish. • On land, it will hunt mice and moles. • As an adult, the egret will start the life cycle all over again!

  33. Stage 3 - Adult Time to record! Draw what the adult egret looks like on your flow map. Write one important thing about the adult egret.

  34. Discussion • Was your hypothesis correct? • How is each stage in the life of an egret different? • Are there any similarities to other animals?

  35. Life Cycle of Carp Did carp always look like this? What is your hypothesis?

  36. 5 stages • An egret goes through many changes during its lifecycle. • Changes are called metamorphosis. Stage 1: Egg Stage 2: Larval Fish Stage 3: Fry Stage 4: Juvenile Stage 5: Adult

  37. Stage 1 - Egg • Eggs are laid among plants. • They grow very quickly. • Changes in water temperature and predators are the biggest threat to the eggs.

  38. Stage 1 - Egg Time to record! Draw what the egg looks like on your flow map. Write one important thing about the egg.

  39. Stage 2 –Larval Fish • Larval fish have a yolk sac attached to their bodies. • They live off of this sac, getting it’s nutrients from it. • When it is fully absorbed, they are called fry.

  40. Stage 2 – Larval Fish Time to record! Draw what the larval fish looks like on your flow map. Write one important thing about the larval fish.

  41. Stage 3 –Fry • Fry are able to eat on their own. • They eat plants, insects from the top of the pond and suck mud from the bottom of the pond. • Fry spend a few months in this stage.

  42. Stage 2 – Fry Time to record! Draw what the fry looks like on your flow map. Write one important thing about the fry.

  43. Stage 4 –Juvenile • Carp continue to grow and mature in this stage. • It can be a stressful time for a fish undergoing metamorphosis (change) and many do not survive. • This stage lasts from 20 days to 4 months.

  44. Stage 4 – Juvenile Time to record! Draw what the juvenile looks like on your flow map. Write one important thing about the juvenile.

  45. Stage 5 –Adult • When carp are able to reproduce they are considered adults. • They have small eyes, thick lips and 2 barbels at the corner of its mouth. • They are green or gray. • Carp can weigh up to 60 pounds!

  46. Stage 5 – Adult Time to record! Draw what the adult looks like on your flow map. Write one important thing about the adult.

  47. Discussion • Was your hypothesis correct? • How is each stage in the life of carp different? • Are there any similarities to other animals?

  48. Life Cycle of Plants in a Pond Did a water lily always look like this? Did a venus flytrap always look like this? What is your hypothesis?

  49. 4 stages • A Venus flytrap will go through many changes during its lifecycle. • See the lifecycle in action! Click here. Stage 1: Seed Stage 2: Seedling Stage 3: Young adult plant Stage 4: Adult plant

  50. Stage 1 –Seed • Seeds are planted and take 4 to 6 weeks to grow. • They will be found in North and South Carolina in wet, humid bogs. North and South Carolina We live here, in Dallas, Texas.
