-Leonardo Da Vinci designed a version of the crossbow in 1500s(to the right). -A disease called Black Death which killed a lot of people in the Middle Ages.
Background On Crossbows The Crossbow really was a good weapon because,it took no skill at all to shoot and had no honor.The English Middle Ages seen buildings such as the Tower of London that helped the Normans to retain their hold on England.The Crusades and Knights in the Middle Ages,including the finding of the Knights Templar.Kings also Queens in the Middle Ages with Richard the lion heart & great plant genet which was Kings from Henry the second (1154-1189) and then to Edward
the third.The one or more hundred year war England vs. France.The battle of Hastings vs. Norman conquest willow effectively took all of the lands of Saxon English.
HELICOPTER By Amanda Bartlett Made by Igor Sikorsky
Facts about the Helicopter • During the first half century of flight is when the helicopters were developed. • The helicopter is a rotorcraft type of vehicle that lifts and thrusts • The first operational helicopter was made in 1936
HOW IT CAME TO BE An Italian inventor Leonardo Da Vinci made drawings of a flying machine.Some experts inspired the modern day helicopter.The first piloted helicopter was invented by Paul Cornu in 1907, but sadly his design did not work.Igor designed the helicopter with one main rotor and one small rotor in the tail part of the helicopter.
HELICOPTER TIMELINE • In 1480 Leonardo da Vinci created a design for a machine that could be described as an "aerial screw".
• In July of 1754, Mikhail Lomonosov demonstrated a small tandem rotor to the Russian Academy of Sciences
• In 1783 Christian de Launoy and his Mechanic Bienvenu made a model with a pair of counter-rotating rotors using turkey feathers as rotor blades. • In 1784 he demonstrated it to the French Academy of Sciences • In 1861 the word helicopter was coined by Gustave de pontoon d'Amecourt , French inventor who demonstrated a small steam-powered model. • In 1885 Thomas Edison was given $1000 by James Gordon Bennett to conduct experiments towards developing towards flight. http://en.wikipedia.org/wiki/Helicopter http://inventors.about.com/od/hstartinventions/a/ helicopter.htm
ROLLER SKATES Roller skates come in 3 basic varieties.Inline skates,quad skates,and quintessence skates.Inline skates design was invented by Jean Joseph Merlin in the 18th century.His invention did not become popular.There was this man named James Plimpton from Massachusetts that invented the rocking skates in 1863.This was an improvement on roller skates.It allowed people to turn easily around corners.Now roller skates are America's number 1 thing.

BENJAMIN FRANKLIN In Boston Massachusetts 1746, Ben Franklin saw other people's electrical experiments, so in 1749 he invented the lightning rod because he loved to study lightning. It could also be called a lightning attractor. A lightning rod USA metal object. To make the lightning rod he used a kite,a key, and a rope.Ben Franklin knew the lightning was a property of electricity.The rod was 8 to 10 feet long with a sharpen point on it.

Velcro By Autumn Miller All about Velcro the invention of Velcro
Velcro was invented in 1948 by a man named George de Mestral. Here is how it was invented.One day he was taking his dog for a walk.When they got home they were covered in cockle burrs.George ran home to his microscope to see why the cockle burrs got stuck to his pants.George got his microscope and inspected one of the burrs that were stuck to his pants. He saw all the small hooks on the burr seed.He put his head up and said "I will design a unique two sided fastener,one side with stiff hook like the burr and the other side with soft loops"like the fabric of his pants.One of the reasons I think we use velcro for shoes is because some boys and girls don't know how to tie their shoes.And thank God of Velcro because kids can just wrap the Velcro around there shoes.Thats why people use velcro.
HELICOPTER Breonna Twitty A helicopter is a rotor craft which means it's a machine heavier than air.The rotors supply the lift and thrust.Because of the rotor,it allows the helicopter to take off,land,stay still,fly forwards,and backwards.The rotor also allows the helicopter to be used in blocked off places and crowded areas.A vertical takeoff and landing does not allow the helicopter to have the capability of staying still for a long periods of time,but a helicopter can accomplish it.

George de Mestral
In 1948, a man named George de Mestral and his dog went for a nature hike. When they returned home, both George and his dog were covered with burrs. When George discovered this, he ran to his microscope to see why the burrs stuck to his pants. George then started thinking" I will design a unique two sided fastener, one side with stiff hooks like the burrs, and the other side with soft loops like my pants. I will call my invention 'Velcro' a combination of the words velour and crochet. It will rival the zipper in its ability to fasten". George's idea was laughed at and resisted, but he still wanted to invent it. With a textile plant in France, he perfected his hook and loop design. In 1955, George de Mestral got his invention patented. http://inventors.about.com/od/astartinventions/a/FamousInvention.htm
CANDY BARS Joseph Fry
In 1847 a man named Joseph Fry discovered ways to mix melted cacao butter and sugar so that he can make a paste that could be pressed into mold. What resulted from this was such a big hit.Soon people had to eat all kind of chocolate bars.They even made drinks out of chocolate We can thank Joseph Fry for all our chocolate bars.He died in 1879

Submarines There are a lot of submarines on earth . There have been lots of people killed by them. Submarines are very large and they have guns on them. They are under water most of the time but sometimes they are on top.There are human powered submarines. Some that have wings can fly.
SPINNING JENNY â€˘ Destiny â€˘The idea was developed by Hargreaves as a metal frame with eight wooden spindles at one end. A set of eight rovings was attached to a beam on that frame. The rovings when extended passed through two horizontal bars of wood that could be attached together.
These bars could be drawn along the top of the frame by the spinner's left hand thus extending the thread. The spinner used his right hand to rapidly turn a wheel which all the spindles to revolve, and the thread to be spun.
http://en.wikipedia.org/wiki/ Spinning_jenny The spinning Jenny was really old but it looked very clean.
Lancelot de mole World War 1 was when the history of the tank began. The army began to use tanks although they were not very dependable. Tanks were designed differently World War 2. They were used a lot in the Cold War. Now it's the main thing we use today. Tank fire power is normally provided by a large caliber main gun.
MICROSCOPE Francisco Aleman
Because of foreign production , quality microscopes have become affordable for all. Zachariah's Jessen the inventor of the microscope , would marvel at the quality of even the most basic microscope found in schools today .Today there are no microscope manufacturers in the us and most of the microscopes come from Germany , Japan ,and China .toy plastic microscopes should be avoided as they not achieve the level of quality of the basic instrument with metal frames and glass lenses. These lenses were not used much until the end of the 13 th century when spectacle makers were producing lenses to be work to make more glasses. http://en.wikipedia.org/wiki/Microscope
