What is Technology?

Learning new facts

Solving problems

? Asking question collecting information finding answer

Inventing new things

It is the innovation, change, or modification of the natural environment in order to satisfy perceived human wants and needs.

The goal of technology is to make modifications in the world to meet human needs.

Technology is the process by which humans modify nature to meet their needs and wants.

Deals with the natural world.

Is very concerned with what is (exists) in the natural world. (i.e.: Biology, Chemistry, Physics, Astronomy, Geology, etc.)

Deals with how humans modify, change, alter, or control the natural world.

Is very concerned with what can or should be designed, made, or developed from natural world materials and substances to satisfy human needs and wants

Is concerned with processes that seek out the meaning of the natural world by “inquiry”, “discovering what is”, “exploring”, and using “the Scientific Method”.

Is concerned with such processes that we use to alter/change the natural world such as “Invention”, Innovation”, Practical Problem Solving, and Design.

Technology is not any more “applied science” than science is “applied technology”.

The power and promise of technology can be further enhanced through the study of technology to assure that all people are technologically literate in the future.

Biology - is the study of living things. A

scientist who is an expert in the study of biology is called a biologist

Botany- is the study of plants. A scientist who is an expert in the study of botany is called botanist

Zoology- is the study of animals. A scientist who is an expert in the study of animals is called a zoologist

Chemistry- is the science of the composition structure, properties, and reaction of matter. A scientist who is an expert in the study of chemistry is called chemist

Physics- is the science of matter and energy and the interaction between them. An expert in the study of physics is called a physicist

Ecology- is the study of how organisms interact with each other. An expert in the study of ecology is called ecologist

Geology- is the study of the structure of the earth’s surface. An expert in the study of geology is called geologist

Meteorology- is the study of weather and climate. An expert in the field of meteorology is called meteorologist

Astronomy- is the study of the heavenly bodies . A scientist who is an expert in the study of astronomy is called astronomer.

Taxonomy- is the study of classification of plants and animals. An expert in the field of taxonomy is called taxonomist.

The Scientist

o Louis Pasteur- a French scientist who is famous for working on fermentation and decay, pasteurization

The Scientist

o Dorothy Hodgkin- a British who was awarded a Nobel Prize in chemistry in 1964.- she determined the structure of biochemical compounds essential in fighting pernicious anemia

The Scientist

o Arturo Alcalaz- considered as the “Father of philippine Geothermal Energy Development”- he is credited for making the Philippines the world’s second largest producer of geothermal energy- won the Magsaysay Award in 1982

The Scientisto Dr. Luis Ma. Guerero

- a bacteriologist , peditrician and renowned medical specialist- first physicians to become a specialist in this field- his contribution to the knowledge of beriberi and leprosy led the prevention of death caused this disease in both infants and adults

Observing- we need to observe very well to know the characteristics and properties of things. We use our senses

Describing • Telling about the features of the object

being observed ( color, shape, size, and texture )

Comparing- telling their similarities or differences

Classifying- grouping objects according to their common characteristics or properties

Measuring- using some measuring tools such as thermometer= used to measure temperature( measured in units called degrees)- use ruler, meterstick or a tape measure to measure length ( express in units called meter)- use weighing scale , platform balance or spring balance to measure the mass of an objects ( gram and kilogram are used to measure the mass)- stopwatch or clock is use to express time

Making Inferences-making good and accurate observation or making an explanation

Science Laboratory Tools

• Microscope – is an optical instrument that enlarges images of very small objects that cannot be seen by the eyes.

Science Laboratory Tools

• Magnifying glass – is an instrument used for observing tiny objects

Science Laboratory Tools

• Test tube – is used for heating small amounts of liquid

Science Laboratory Tools

• Test tube holder – is a metallic device used to hold a test tube

Science Laboratory Tools

• Graduated cylinder – is used for measuring volume of liquids like water, oil, and other solutions

Science Laboratory Tools

• Alcohol lamp – is used for heating materials

Science Laboratory Tools

• Evaporating dish – is a porcelain dish used in evaporating a chemical solution

Science Laboratory Tools

• Beaker – is a thin glass vessel used as container for fluids, it has graduation or masks for the measurement of volume

Science Laboratory Tools

• Thermometer – is used for measuring temperature

Science Laboratory Tools

• Funnel – is a device used when pouring liquids or fine particles to a small-mouthed container

Science Laboratory Tools

Extra care must be observed when using laboratory tools and materials .Always clean and keep them properly after use.
