WE WILL NOW COUNT DOWN OUR

TOP TEN INVENTIONS!

NUMBERTEN

Transistor• We would not have

computers in our houses without the transistor because they would be too BIG!

• Without transistors we would have to plug in all of our radios.

• Transistors were invented in 1947 at Bell Labs.

NUMBERNINE

Shelter• Early man who lived

1,000,000 years ago made nests in trees, fields, and sometimes in caves.

• Whenever they started farming they built more permanent shelters.

NUMBEREIGHT

Computer• Computers store great

amounts of information.

• We can talk long distances by using e-mail.

• The first computer that was electronic and fully –programmable was invented in 1941, by Konrad Zuse.

NUMBERSEVEN

Printing Press• The printing press was invented by

German Johannes Gutenberg in the 1440’s.

• It allowed us to print things like books without having to write it if we wanted a copy.

• Without it, not very many people could go to school, so a lot of us would not be very educated as we are now.

• Other people in Europe claimed to have invented the printing press, but Gutenberg got the most credit by scholars.

NUMBERSIX

Transportation• Transportation helps people

and products get from one place to another.

• Karl Benz invented the 1st gasoline powered three-wheeled car in 1885 in Germany. It crashed going two miles per hour when the driver lost control and hit a wall.

• Gottlieb Daimler invented a 4-wheeled car that same year.

NUMBERFIVE

Alternating Current• Nicola Tesla invented

alternating current and then sold his idea to Westinghouse in 1885.

• Thomas Edison thought direct current would be better, but Tesla’s idea is what we use today.

• We are glad that Nicola Tesla invented alternating current so that we can plug in to electricity in our houses.

• Ad;slkfja;sljfa;slfjdas;lkjfasldfjalkjdfl;aksjdf;lkasdfj;lkasj

NUMBERFOUR

•The wheel was invented about 5000 B.C.

•The first wheel was found in Mesopotamia, but no one knows who really invented it.

•The first wheels were probably made out of logs. Before wheels people used wedges to move heavy things. •Aksldfjsa;lkdjfa;lksdjf;alksdfja;lkjdf;lkasjdflkajdsflkajsdf;lkajhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhsd;lfkjasd;lfjasd;lfkjas;dlsgfhsfghsfgl;ksjfsgkldgjklsdlgksdjflskgjdf;lsjd;lgjlksfjlslgsjdlskjsg;ldjljs;lkjlkjsl;dkgjflkgjdlj;dsfgjs;dlfkgjs;lfdgjsdlf;gj;lsjlksjl;ksfdjg;lskdgj;lksg;jlskgj;lsj;lsdjsdlj;lsdj;lj;lsjlsjs;dlfjgs;dlfjgdsl;fjgsd;flgjd;slj;sdlj;sldjgs;ldjsd;ljs;ldj;sldjs;ldgj;sdlfgjsd;lfjgdslkjds;fljkgdl;fjgsdlf;jgdsl;fgjsdlf;gjsd;lfgjsdl;fgjsdf;lgjdsf;ljgdslf;jg;dlsjkjhbhbjnjph;jkhp;pkj;jblpkj;pkjjpkplohlopblm.n nmhhhfk

Agriculture• Agriculture was probably

developed in South Asia and Egypt.

• It is believed to date from 9000-7000 B.C.

• Early man grew crops such as wild barley, beans, water chestnuts, and pumpkins.

• Agriculture is important because without it, we would have to look for food.

NUMBERTWO

• Long ago plants were used as medicine. Aloe was used to heal burns, willow bark was chewed to relieve pain, and yucca was used to make soap.

• Penicillin was accidentally invented by Robert Fleming in 1928 when he noticed that mold killed bacteria.

• Without medicine people could get very ill.

•Nobody really knows by whom, when, or where language was invented.

•It has been around since at least 40,000 B.C.

•Without it we couldn’t understand each other.
