  1. Comparing Life Cycles 4.10C – explore, illustrate, and compare life cycles in living organisms 5.10C – describe the differences between complete and incomplete metamorphosis of insects

  2. Vocabulary Cycle-A series of repeating events that usually lead back to a starting point. Metamorphosis- A physical or structural change (transformation).

  3. Life Cycle Table

  4. Is this an example of complete or incomplete metamorphosis? How do you know?

  5. Is this an example of complete or incomplete metamorphosis? How do you know?

  6. Is this an example of complete or incomplete metamorphosis? How do you know?

  7. Is this an example of complete or incomplete metamorphosis? How do you know? Life Cycle of a Cricket

  8. Life Cycle of a Frog

  9. Eggs Adult Frog 1 5 Tadpole 2 Can you label the steps? Tadpole with legs 3 4 Froglet

  10. Comparing Tadpoles to Frogs

  11. Life Cycle of a Bean Plant 1. Seed is planted 2. Seedling grows roots 4. Plant is fully grown; bean pod begins to grow 3. Plant pushes above the soil; leaves begin to form

  12. Check your Understanding • What is the major difference between a complete metamorphosis and an incomplete metamorphosis? • What does this illustration show? Complete metamorphosis has 4 stages and the hatched insect does not look anything like the adult it will become; incomplete metamorphosis is when the newly hatched insect looks like a smaller version of the adult. The life cycle of a butterfly – complete metamorphosis

  13. 3. Describe the life cycle shown in this illustration. • What type of life cycle is described below? Egg  nymph  adult The acorn is the seed that gets planted in the ground. The seed grows into a sapling plant which then becomes the oak tree. The oak tree then drops acorns to the ground and the cycle begins again. Incomplete metamorphosis – only 3 stages
