Airplane – [air-pleyn] – /ˈɛərˌpleɪn/

An airplane or aeroplane is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world’s cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones.

1804 The first winged aircraft was made
Sir George Cayley, in England, made the first winged aircraft. He spent many years studying flight.

1896 The first powered aircrafts
Samuel Langley made a steam-powered airdrome. It was unmanned, and it flew for about a half mile.

1901 The first gasoline-powered model
After continuing his studies, Mr. Langley came up with a gasoline-powered engine for his airdromes.

1903 The Wright Brothers’ flights
Orville and Wilbur Wright made the first successful manned flights near Kitty Hawk in North Carolina.

1910 The use of air craft carriers is thought up
Eugene Ely decided to try landing and taking off from a ship. He did both successfully, and it paved the way for future air craft carriers.

1918 Airmail is created
The United States Postal Service began using airplanes to deliver mail across the country. It was three days faster than carrying the mail by train.

1919 The first flights across the ocean began
The US Navy made some of the first flights across the Atlantic Ocean. Soon after that, passenger flights began.

1925 Better planes and better engines
In 1925, new lightweight, air cooled engines were created. This made the airplanes run better and faster.

1927 Charles Lindbergh flies across the ocean alone
Mr. Lindbergh made the first solo flight across the Atlantic Ocean. He flew from New York to Paris by himself.

1933 The first passenger planes are made
Boeing made the 247 plane. It could seat up to 10 people.

1952 The “area rule” is discovered
Pilots and engineers in California tested a theory called the area rule. Using it, they were able to make sleeker, faster airplanes without using bigger engines.

1969 The first larger passenger jets are made
Boeing came out with the 747. It was a huge jet that could seat many more than the previous 10 people.

1990 B-2 Bombers are developed in 1990’s
During the 90’s engineers invented planes using non-metal materials that couldn’t be detected by radar. Shortly after that, the stealth planes were invented. The production of bigger and better airplanes continues today, and one can only dream what will come next!



Apple – [ap-uhl] – /ˈæpəl/   

An apple is an edible fruit produced by an apple tree. Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition.

Scientific Name: Malus domestica
Subspecies: Golden Delicious · Red Delicious · Cox’s Orange Pippin · Mutsu · Ralls Janet · Fuji · Jonathan · Gascoyne’s Scarlet
Biological Rank: Species
Did You Know: The apples you’re buying could be one year old.


Ant – [ant] – /ænt/

Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants appear in the fossil record across the globe in considerable diversity during the latest Early Cretaceous and early Late Cretaceous, suggesting an earlier origin. Ants evolved from vespoid wasp ancestors in the Cretaceous period, and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.

Scientific Name: Formicidae
Biological Rank: Family
Length: 0.24 inch – 0.98 inch (Carpenter ant) · 0.08 inch (Pharaoh ant, Worker) · 0.24 inch – 0.35 inch (Black garden ant, Queen) · 0.2 inch – 0.28 inch (Black garden ant, Drones)
Clutch Size: 20 (Carpenter ant, Queen)
Lifespan: 0.3 years – 1 years (Pharaoh ant, Queen)
Did You Know: Ants Defend Plant life in Exchange for Shelter.
