3. • It is defined as a precursor to the unfolding or existence of
something.
• Antecedents of science and technology are factors that paved
way for the presence of advanced and sophisticated scientific
and technological innovations today.

5. • Ancient civilization paved the way for advances in science and technology.
• These advances during the ancient period allowed civilizations to flourish by
finding better ways of communication, transportation, self-organization and
ways of living.

6. • The invention of ancient
wheel is credited to the
Sumerians.
• People from ancient
civilization used animals
as means of
transportation.

7. POTTER’S WHEEL ANCIENT WHEEL

8. • Before the invention of papyrus,
writing and record-keeping is done
on stones and tablets.
• Around 3000 B.C., the ancient
Egyptians began writing on a
papyrus.
• It is made up from a pith of plant
called cyperus papyrus.

9. • It is a hand-operated device
used for lifting water.
• A tool used and invented by
ancient Egyptians to irrigate
land.
• Its invention introduced the
idea of lifting things using
counterweights.

10. • Discovered in 1902 and
retrieved from the waters of
Antikythera, Greece.
• It is a mechanism similar to a
clock for it has a circular face
and rotating hands.
• It is believed that this
mechanism is used to predict
astronomical positions and
eclipses.

12. • It is a steam-powered turbine
which spins as the water container
at its center is heated.
• It is also known as the Hero’s
engine.
• At first, it doesn’t served any
practical purpose. It is believed to
be one of the “temple wonders” at
that time.

13. • The major advances in scientific and technological development took place
in this period.
• These advancements include constant increase if new inventions,
innovations in traditional production and the emergence of scientific
thinking and method.

14. “The heavy plough turned European agriculture
and economy on its head. The fields with heavy,
fatty soil became those that gave the greatest
yields.”
- Prof. Thomas Andersen
- Because of the invention of heavy plough,
northern Europe saw rapid economic
prosperity.

15. - Around 850 A.D., Chinese alchemists
accidentally invented the gunpowder.
- Prior to the invention of
gunpowder, swords and spears
were used in battles and wars.
- The invention of gunpowder has
allowed advanced warfare such as
fiery arrows, cannons and
grenades.

16. • They realized that using paper
money brought advantages
because it is easier to keep and
transport.
- Paper money was first used by
Chinese in 17th century.
- Before the introduction of paper
money, merchants and traders
used precious metals such as gold
and silver.

17. • The development of
mechanical clock helped the
people in accurately keeping
the track of time.
• The sophistication of
clockwork technology
drastically changed the way of
spending the day and work
patterns were established.

18. • A machine used to transform fiber
into thread or yarn and eventually
woven into cloth.
• It is theorized that the Indians are
the one invented the spinning
wheel between 6th and 11th
century.
• It sped up the rate of manually
spinning fiber by 10 to 100 times.

19. • Historical period when people realized the importance of the efficiency of
transportation, communication and production.
• Industrialization took place but with greater risk on human health, food
safety and environment.

20. • This is used to discover
important astronomical
discoveries such as craters and
mountains in moon.
• Invented by Galileo Galilei that
can magnify 20 times larger
than a regular glasses.

21. • Nowadays, microscope is
used in many scientific
studies in the area of
medicine, forensics and
genetics.
• Invented by a Dutch
Zacharias Janssen in
1590’s.

22. • Prior to this invention, a drawloom
is used which requires two persons
to operate.
• Built by French weaver Joseph
Marie Jacquard which simplifies
textile manufacturing.

23. • They demonstrated that slightly-
tilted wings are the key features of
a flying aircraft.
• Invented by Orville Wright and
Wilbur Wright.

24. - Invented by Scottish engineer John Logie
Baird in 1920s.
- British Broadcasting Corporation used this
for its earliest television programming in
1929.
- This first television is mechanical and not
the same as the television we have
nowadays.
