  1. Hi Jessica,Ariana and Alice

    I listened to your movie about mealworms and I really liked it. I thought the pictures you chose were excellent. I just want to say maybe next time you could speak a bit more clearly.

    Great job girls!

    Butterflies attach their eggs to leaves with a special glue. Fully grown caterpillars attach themselves to a suitable twig or leaf before shedding their outside layer of skin to reveal a hard skin underneath known as a chrysalis. An adult butterfly will eventually emerge from the chrysalis where it will wait a few hours for its wings to fill with blood and dry, before flying for the first time. Butterflies often have brightly coloured wings with unique patterns made up of tiny scales. Butterflies have taste receptors on their feet. There are between 15000 and 20000 different species of butterfly.


    • Fantastic research Lachie!

      I love how you remembered to add the source for your information.

      A goal for next time is to divide your writing into paragraphs like you do in your writing book.

      Keep up the great work.

  3. Here is my mosquito lifecycle.
    A female mosquito lays eggs in water. The eggs hatch into a larva. It lives in water and breaths air through a tube. It sheds its skin until a pupa forms around its body. As the pupa cracks open it is now an adult mosquito.

    • Terrific research Daniel.

      Some goals to improve your blog writing next time are to write in paragraphs and to include your information source.

  4. First the mother crocodile digs a hole in the ground where she will lay her eggs. She lays multiple eggs at a time and sits on them for 3 months to protect them. Then the eggs hatch and the mother crocodile then leads her babies to the water. 2 to 8 years old, crocodiles are in their youth stage. At 8 to 10 years the crocodile is considered an adult. it can grow up to 6 meters long.

  5. The Lifecycle of a Bird

    Birds are hatched from eggs that the mother bird takes care of. When the bird is born it is bald and can not fly.

    When the bird is a bit older and can fly, it is a young bird and is a bit smaller than the average adult bird. At this stage they are ready to leave the nest.

    When the bird is an adult, it looks after it’s eggs by sitting on them and protecting them. Then the eggs hatch and the lifecycle starts again. and


    • Great work Ariana.

      You have told us about the three stages of the life cycle of a bird. While they are too young to fly is there anything that their mother bird teaches them?

      Great paragraphing and reference.

  6. Life Cycle of a Fresh Water Snail

    Freshwater snails live in lakes, ponds and rivers all over the world.

    Able to reproduce at a very fast rate, some types of snails are considered pests. Other types, like apple and mystery snails, make popular aquarium pets because of their unusual spiral-shaped shells and colouring. There are over 4,000 different kinds of freshwater snails, with varying methods of reproduction and a life span that ranges from weeks to a few years.

    Many species of freshwater snails are hermaphrodites. This means they have both female and male organs. Able to make and fertilize its own eggs, a single snail can quickly over populate a new habitat. On average, it has a one-year life span and a snail can lay up to 1000 eggs.

    Most freshwater snails create and lay eggs. Most species produce gelatinous lumps of jelly-like eggs in batches of five to 40 eggs. Eggs collect on plants, or in an aquarium, they can be seen often to the side of the glass, hatching after six to eight days. Some snails lay a single egg close to the water’s edge.

    Depending on the species and environmental conditions, most snails become fully grown in four to seven weeks.

    The availability of food, as well as the temperature and conditions of the water the snails live in, determine the life span and the reproductive habits of the snail. Warm, snail-friendly water that has plenty of nutrients in it results in many new snails being born.


    • Wow fantastic research Bridget!

      You have written a very thorough explanation of the life cycle of a water snail.

      Well done on your layout, spelling and grammar as well as the bibliography.

      Definitely a model of success.

  7. THE LIFE CYCLE OF A FROG!!!!!!!!!!!!

    The life cycle begins when frogs lay their eggs in water or wet places. A floating clump of eggs covered with sticky gel is called frog spawn.

    Out emerges tadpole. Tadpoles grow until they are big enough to break free into the water. It has a long tail, and lives in the water.

    After about five weeks, the tadpole begins to metamorphosise. It starts to grow hind legs, which are soon followed with forelegs. Their tails become smaller and lungs begin to develop. It now has to go to the surface to breathe.

    Eleven weeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water. This frog will live mostly on land but also swim in water. The frog begins to eat insects.

    There are approximately 4,740 species of frogs around the entire world.

  8. The Life Cycle Of A Giraffe

    The life cycle of a giraffe starts with birth; giraffes usually give birth to a single calf after a 16-month pregnancy.

    The newborn calves weigh about 65 to 90kilograms and are about 182 centimeters tall. After this, they are nursed for nine to 11 months, and then left to live on their own up until three to five years old.

    Once they turn about seven years old; mating starts and continues year-round, peaking especially during the rainy season.

    The average lifespan of a giraffe is approximately 20 years although some die younger, while others live longer.

  9. The life cycle of a Whale

    Baby whales are called calves. The gestation period in most whale species is 11 to 16 months. Generally a single young is born, tail first likely in order to prevent drowning, and twins are very rare. The newborn calf is usually one-quarter to a third the length of the mother.

    The adolescent or juvenile stage runs from the moment the calf is weaned to when it reaches sexual maturity. Again, this varies according to the species.Once weaned, juveniles start to mix with whales of the same age and gender. Male juvenile whales will form bachelor pods and leave their original pod. They will start searching for sexually mature cows, female whales, with whom to mate. Female juveniles also start exploring outside their pod, but they are more likely to return to their matriarchal pod or to their mother.

    The adult whale stage starts when the whale reaches sexual maturity. This can occur between the ages of six and 13 years, varying dramatically depending on the species.

  10. The Human Life Cycle

    A child is born after nine months in its mother’s uterus. Babies must be fed and looked after by their parents. As a baby it will grow its first teeth and start to walk.

    At least by the age of five a child can talk, run and walk. A child is still dependent on its parents. Children will lose their first set of teeth and grow another set.

    At thirteen a child becomes a teenager. At this time boys and girls will start developing into adults. Teenagers like to be independent and do things by themselves.

    At eighteen a teenager becomes an adult. They are fully independent. Adults don’t grow any more but they must look after their body to live a happy and healthy life.



    A female turtle lays eggs on a nesting beach, normally in the tropics, from six weeks to two months(8 weeks)later a tiny baby turtle appears. They take their first swim,often unknown where they are, the hatchlings dodge as many predators before returning to seaside/coastal waters. At ten to fifty years after hatching the turtles are able to mate, but only the female comes ashore to lay the eggs.
