  1. The Dragonfly

  2. Dragon flies get their interesting name from their strong jaws that they use to catch flies. Dragonflies begin their life as an egg. After about two weeks, the eggs hatch and a “baby” immature dragonfly emerges. These young dragonflies are not as attractive as the adult, however, when it reaches maturity, the skin begins to split and an adult dragonfly emerges. In about two days the beautiful colors of a dragon fly emerges. Sadly, however, a dragonfly will live its’ adult life for only a few months.

  4. Dragonflies are not flies! They are insects, but because of their four wings they are not flies. Dragonflies are very beneficial to people because of all of the mosquito’s they eat. Dragonflies are also very hard to catch and wonderful hunters due to their excellent eye sight. Their beautiful large eyes are made up of thousands of six-sided units that allow the dragonflies to see at many angles.

  5. NSES Standard Addressed… • TEACHING STANDARD D:Teachers of science design and manage learning environments that provide students with the time, space, and resources needed for learning science. In doing this, teachers • Structure the time available so that students are able to engage in extended investigations. • Create a setting for student work that is flexible and supportive of science inquiry. • Ensure a safe working environment. • Make the available science tools, materials, media, and technological resources accessible to students. • Identify and use resources outsidethe school. • Engage students in designing the learning environment.

  6. Children’s Literature Connection • “Eliza and the Dragonfly”by Susie Caldwell Rinehart • A picture book story about the life cycles of the dragonfly.

  7. And a few more fun facts… • dragonflies have a top flight speed of up to 100 km/h • each dragonfly eye contains up to 30,000 lenses • the eyes' position on the dragonfly gives the insect a 360 degree field of vision • although 80% of the brain is devoted to sight dragonflis are not able to register detail well • the oldest fossilized record of a dragonfly is from the Carboniferous Period, over 300 million years ago • the Nootka word for dragonfly translates as "clacking stick," the name given to cedar tongs used to remove coals from the fire
