In order to prepare myself to teach my TEK, (Grade 2 TEK 10(C): “Investigate and record some of the unique stages that insects undergo during their life cycle,”) I have done some researching on the life cycles of different species, thought of questions teachers might ask before teaching the lesson plan or students might have during it, and ways to relate it to topics learned in previous NSC classes. Before beginning teaching the life cycles of a frog, bumble bee, butterfly/moth, and dragonfly one must become very familiar with the material. So, first of all, study the life cycle of a frog. Looking at a diagram of each life cycle while reading the material will be very helpful. Female frogs first lay jelly-covered eggs in the water. There are thousands of eggs and they take about 10 days to hatch. After hatching, eggs become tiny tadpoles. The tadpole at this stage in life is eating, swimming, and growing. It has a tail to help it swim. As the tadpole grows older it sprouts legs and is now called a “Froglet” as it is beginning to look more like a frog. As it grows legs, its tail shrinks. The froglet will soon grow front legs and develop lungs, its eyes and mouth grow larger, and its tail will continue to shrink. Once the Froglet grows large enough and loses its tail, it is officially considered a Frog. It can now live outside of the water and leap around to travel places as oppose to swimming. Frogs tend to hibernate in the winter while it is cold, and then in the spring find a mate, reproduce, and lay eggs again so that the process can continue. A bumble bee queen will mate and reproduce at the end of summer or early autumn, and then hibernate in the winter. Once impregnated, the queen will feed on nectar, and pollen to get... ... middle of paper ... ...g into a dragonfly. It will most likely live in a pond or marshy area because the water is calmer than a river or stream. The nymph can take up to four years to grow in the water. The nymph will eat things in the water including plants, other insects, and even other baby dragonfly nymphs. The nymph will not leave the pond or marshy area until the spring because it is too cold to come out during the winter. Once the nymph is grown and fully developed it will crawl out of the water, or up the stem of the plant, and shed its skin known as the “Exuvia.” The exuvia can be found stuck to the plant for a very long time. The adult dragonfly will then fly away and go find a partner to mate with. It will only live about two month during the adult dragonfly stage. After familiarizing myself with this information, I am ready to teach the lesson, and so should other teachers.
As the epigraph for chapter 14 states, “A queenless colony is a pitiful and melancholy community; there may be a mournful wail or lament from within… Without intervention, the colony will die. But introduce a new queen and the most extravagant changes take place” (277) The initial changes with the introduction the new queen seem insignificant, but they are anything but. It begins with Lily taking over May’s old room. It is extremely symbolic of her fulfilling the role left empty in the house. Then, August stood up to T. Ray for Lily to ensure that she would stay in the house with her, effectively keeping her safe, and under her watchful eye, just as she had with May. Many other changes, large and small occur as Lily transfers to her new role, but each is significant to the bee symbolism.

Honey bees, or Apis mellifera, are social insects, despite what preconceptions there are about them. They are commonly divided into three divisions of class. The first is the worker bees. They are born from fertilized eggs and are the females that are not sexually developed. They are the ones that people usually associate with honey bees. Their main job is to search for food, and build and protect the hive from predators. They have one stinger that, when used, the worker will die. Next is the queen. Her job is to lay the eggs that will hatch into the new generation of bees. Queens also controls the hive and the activities within the hive by producing chemical pheromones the steers the behavior of the bees. She possesses a stinger and can sting and kill multiple times and not be killed herself. (Hoover, S, et al. 2003) In most hives, only one queen is present and if that queen dies, the workers will create a new queen by feeding one of the workers with a special diet called “royal jelly.” This allows the sterile worker to develop into a fertile queen. The last class division i...
could have saved me much distress, and I urge my fellow novice educators to take it to heart.
“If you would just get up and teach them instead of handing them a packet. There’s kids in here that don’t learn like that. They need to learn face to face. I’m telling you what you need to do. You can’t expect a kid to change if all you do is just tell ‘em.” Texas student, Jeff Bliss, decided to take a stand against the lack of teaching going on in his class (Broderick).
It is at this point that the school and its teachers ought to step in.
Some species of damselflies lay their eggs either inside or on plant tissue, which is either above or in water. Some females climb beneath the surface of the water to position their eggs and remain there for an hour, or perhaps more. Some species submerge their abdomen in the water, so the eggs wash off, or put them on leaves close to the water’s edge. This is sometimes done while the damselfly is in flight. Other species simply allow their eggs to drop onto the surface of the water while they are flying (Corbet, 1999).
Frogs live on every continent except Antarctica, but tropical regions have the largest amount. Like all amphibians, frogs spend half their lives near water because they must return to the water to lay their eggs. Frogs live underwater mostly when the are growing up to be an adult frog and when they are laying their eggs. When they hatch under water they are tadpoles and the breath with gills and swim using a tail. As they mature they loose their tail and they develop to be able to breathe air. During an extensive period of heat, a drought, frogs can enter a period of damancy similar to hibernation called starvation. Most of the frogs live in tropical and semitropical regions, most species of frogs breed in the spring or in early summer. Although the different species my vary in size and color, mostly all frogs have basic body structure. They have large hind legs, short front legs and flat head and body with no neck.
Most of the species from habitat one are Diptera. There was a total of thirteen Diptera’s in habitat one. Cup one had the least amount of individual species with four. Habitat two had more individual species than habitat one. There was a total of seventy-nine species from habitat two. Like in habitat one most of of the arthropods from habitat two were Diptera. The was a total of eighteen Diptera’s in habitat two. Cup six had most of the Diptera’s with thirteen. Orthoptera was second in the number of individuals with sixteen. Orthoporea’s are crickets and
There are nearly one million species of insects known. Insects are defined by having six legs and a body divided into three segments: head, thorax, and abdomen. Chitin is an organic material that makes up an insects exoskeleton. There are three life cycles of insects, ametabolous or incomplete and paurometabolous or gradual, and homotabolous or complete metamorphosis. These life cycles are important in the aging of insects for aiding in legal investigations, (Houck and Siegel. Entomology).
Well in the spring all the males and young winged queens leave their nest and fly high in the air and mate. The few ant queens that survive this “marriage flight” cast off their wings and instinctively begin to look for a spot to start a new ant colony. After making a nest, the young queen ant seals off the entrance and begins to lay eggs. Some of the first batch are eaten by the queen for nourishment. When the surviving eggs hatch, they become like larvae. After a few weeks each larva spins a cocoon around itself and pupates.
Insect, small, air-breathing animal characterized by a segmented body with three main parts—head, thorax, and abdomen. In their adult forms, insects typically have three pairs of legs, one pair of antennae, and in most instances, two pairs of wings. Insects rank among the most successful animals on Earth. About one million species of insects have been identified so far, which is about half of all the animals known to science. That is why for every pound of human on the earth there are 10 pounds of insects. So that is why there are many reasons why insects are so successful, their exoskeleton, their size, their body function, the way they reproduce, and their development of metamorphosis.
The life cycle of a butterfly is perhaps one of the most beautiful and astounding processes in nature. The four stages a butterfly goes through to become the beautiful flying insects are just as interesting as the vibrant colors and patterns on the wings of the various species of butterflies. The four stages are as follows: the egg, the caterpillar, the pupa, and the emergence of the butterfly. Each stage is vital to the development of the adult butterfly. Perhaps the most interesting piece of the complicated puzzle that is the butterfly life cycle is the process of metamorphosis that happens in stage three. Similar to how a tadpole becomes a frog, a larva (caterpillar) morphs into a beautiful brilliantly colored butterfly.
