1TECHNOLOGY VS SCIENCE: Like brothers! Or sisters!How are they similar & different?
2After this presentation, your goal is to.. Understand the definition of technologyDetermine the difference between science and technologyDiscover the human limitations, and the technology we use to overcome themExplore the characteristics of technologyKnow the resources of technologyFind out what a Renewable and Nonrenewable resource isDescribe how technology has led to more scientific knowledge.
3WHAT IS TECHNOLOGY?The application of knowledge, tools, and processes to solve practical problems and extend human capabilities.QUIZ: What is TECHNOLOGY?A space suit?The internet?A newborn baby?Grass?An inoculation against smallpox?--A chair?A hammer?
4[1.What is technology? [accessing knowledge] [googling] [finding a better way][all of the above][Default][MC Any][MC All]
6Science is the accumulation of knowledge. TECHNOLOGYScience is the accumulation of knowledge.Technology is the application of knowledge.Einstein’s accumulation of e=mc2 created a legacy of technology. e=mc2 stands for "energy equals mass times the speed of light squared" Radiocarbon dating, which archeologists use to date ancient material, is an application of the formula. "The decay products that we see in carbon dating—that energy is directly obtained from the missing mass that you see in E = mc2," Gates says.Thomas Edison’s applications of inventions: Phonograph (initial invention leading to the iPod), Motion Picture Camera “Kinetoscope”, Light bulb, devices for maintaining constant voltage for electrical current, light sockets with on-off features.
7WHY natural things happen the way they do. SCIENCETECHNOLOGYSCIENCE is the study ofWHY natural things happen the way they do.TECHNOLOGY is the use of knowledge to turn resources into the goods and services that society needs.
8Study how the earth was formed and what it is made from. SCIENTISTTECHNOLOGISTStudy how the earth was formed and what it is made from.Use the materials in the earth to make useful objects.
9Study the relationship between the earth, planets, and the stars. SCIENTISTTECHNOLOGISTStudy the relationship between the earth, planets, and the stars.Build and launch space shuttles and satellites.
10Technologists create new materials with improved characteristics. Carbon NanotubeSCIENTISTTECHNOLOGISTStudy materials under a microscope to learn why they have the characteristics that they do.Technologists create new materials with improved characteristics.Nanotubes can make electrical wires that don’t loose electricity through heat!Except: Scientists can only grow nanotubes an inch long! Check back in 20 years!Carbon Nanotube: Strongest fiber known to humans. Also, superconductive meaning it conducts electricity with little to no loss. Current power transmission technology’s largest problem is “line loss”, the loss of electricity in the form of heat. Carbon nanotube fibers would allow us to set up giant solar energy fields in a desert and transmit that power anywhere we’d like it with no power loss. Problem: technologists and scientists have not successfully grown a carbon nanotube longer than an inch.
11Discover the way the human body works. SCIENTISTTECHNOLOGISTDiscover the way the human body works.Make artificial hearts and limbs.
12Discover genetic codes that determine the nature of life. SCIENTISTTECHNOLOGISTDiscover genetic codes that determine the nature of life.Use codes to develop new medicines and vaccines.Genetic research is working to cure or improve the following sicknesses. Anyone know anyone with:Asthma. 1 in 3 children are affected with 550,000 school days lost each yearBronchiectasis. A lung disease that causes 40 teenage deaths each yearChildhood cancers. Our highest cause of death in childrenCystic Fibrosis. An incurable lung disease which affects thousands of childrenDiabetes 1. Treatment costs over $1 million in a lifetimeGenetic research. 1 in 30 babies are born with a genetic malformationHeart disease.Obesity. A growing epidemic in the USAPneumonia.Pre-term babies. Costs $50m per annum to fund treatment and care
13SCIENTISTS & TECHNOLOGISTS ARE A TEAM!Biologists, chemists, and physicists are…ScientistsArchitects, engineers, product designers and technicians are…Technologists
14[2.Which is the technologist?] [biologist][architect][chemist][physicist][Default][MC Any][MC All]
15SCIENCE answers the question… Why do people from Asia look different from people in South America?Why does this material release electricity when exposed to the sun?Why does this chemical react with this one?Why does the heart beat?Why is the sun hot?Why does glass break?Why do we get cancer?Why is the average global temperature rising?WHY?Why do some people struggle with their weight?Why do we age?Why does lighting strike?Why are teenagers so moody?Why do geese fly south for the winter?Why do we have families?Why do we hear when someone talks?Why do we have earthquakes?Why does the moon look like cheese?
16TECHNOLOGY answers the question… How can we best transport people from Asia to South America?TECHNOLOGY answers the question…How can we make electricity with the sun?How can we make a non-explosive gasoline?How can we protect ourselves from the sun?How can we make an artificial heart?How can we make an unbreakable glass?How can we stop cancer?How can we end global warming?HOW?How can we stop obesity?How can we stop aging?How can we avoid being hit by lighting?How can we make teenagers less moody?How can we moniter gees flying south for the winter?How can we create a home for a family?How can we help a deaf person to hear?How can we make buildings earthquake-proof?How can we land on the moon?

30REVIEW What is the definition of technology? Which is the technologist: Biologist or Architect?What are the human limitations? What technology do we use to overcome them?What are the characteristics of technology?Name the resources of technologyName three examples of a Renewable and Nonrenewable resource.WHO ASKS HOW? WHO ASKS WHY?
31Describe how technology has led to more science knowledge.-steam enginesdeveloped many laws and theories“thermodynamics”-Dutch satellites advanced astronomy-electron microscope = cell study-liquid fuel rockets -bombs-spacecraft-- moon landing- soil samples-probes to planets.
