Lesson 1: What is Technology?

Computers

- stores information - process and send information with great speed

What is an example of Transportation technology?

Global Positioning System (GPS)

How do solar panels improve our lives?

Solar panels gather the sun's energy and change this energy into electricity. People use energy for many things (cook food and heat homes) but we may be running out of some energy sources. The discovery of how to use solar energy helps solve this problem. Solar energy is energy that comes directly from the sun. - Solar panels provide a new way of getting energy.

What is an example of Medicine technology?

X-rays and vaccines

X-rays

allow doctors to look inside the body without touching it. Today, doctors also use digital technology to do this

What are examples of computer technology?

computers, calculators, cameras, appliances, cars -all use computer chips

Scientific discoveries can lead to ...

development of new technology

Vaccine

medicines that protect you from disease (scientists discovered that viruses and bacteria cause disease so they developed vaccines)

Computer chips

send and receive huge numbers of electronic data signals very quickly

Technology helps people ....

solve problems and improves their lives

A global positioning system (GPS) relies on signals sent from a(n)

space satellite

Technology

the use of science knowledge to invent tools and new ways of doing things.

scientists

they make scientific discoveries that lead to the development of new technologies

Global positioning system (GPS)

this technology relies on space satellites that send signals to Earth. A ship's GPS computer uses the signals to figure out the ship's location. ****Signals from satellites can track the exact location of a car

Engineers

use knowledge and scientific discoveries to develop technologies that change and improve the way people live

What technology protects people from diseases?

vaccines
