Question 1

What is the earliest type of clock?

Accepted Answer

The earliest type of clock was the sundial. It used the sun’s shadow to tell the time.

Question 2

How did sundials work?

Accepted Answer

Sundials had a stick or pointer that cast a shadow on a flat surface marked with hours. As the sun moved across the sky, the shadow pointed to different hour marks.

Question 3

What was used for timekeeping before clocks were invented?

Accepted Answer

People used the sun, the moon, and stars to figure out the time. They also used simple tools like sundials and water clocks.

Question 4

What is a water clock?

Accepted Answer

A water clock, or clepsydra, measured time by the flow of water. As water dripped from one container to another, it showed how much time had passed.

Question 5

Why were mechanical clocks invented?

Accepted Answer

Mechanical clocks were invented to tell time more accurately and without relying on the sun or water. They used gears and weights to keep track of time indoors.

Question 6

How did mechanical clocks work?

Accepted Answer

Mechanical clocks used gears and a swinging weight or pendulum to keep time. The movement of these parts helped the clock hands move to show the time.

Question 7

What is a pendulum clock?

Accepted Answer

A pendulum clock uses a swinging pendulum to control the movement of the clock’s gears. This made timekeeping much more accurate.

Question 8

When were pendulum clocks invented?

Accepted Answer

Pendulum clocks were invented in the 1600s by a scientist named Christiaan Huygens. They helped people keep much better time than before.

Question 9

What is a pocket watch?

Accepted Answer

A pocket watch is a small watch that can fit in your pocket. It was invented so people could carry the time with them wherever they went.

Question 10

How did early people tell time at night?

Accepted Answer

Early people used the stars and the moon to tell time at night. They also used special candles or oil lamps that burned for a set amount of time.

Question 11

What is an atomic clock?

Accepted Answer

An atomic clock is the most accurate type of clock. It uses the vibration of atoms to measure time very precisely.

Question 12

Why are atomic clocks important?

Accepted Answer

Atomic clocks are important because they help keep time very accurately. This is useful for things like GPS and internet networks working correctly.

Question 13

What is a digital clock?

Accepted Answer

A digital clock is a clock that shows the time with numbers on a screen. It doesn’t have moving hands like an analog clock.

Question 14

How are modern clocks different from old clocks?

Accepted Answer

Modern clocks are usually more accurate and can be digital or use tiny electronic parts. Old clocks were often larger and used mechanical parts like gears and weights.

Question 15

Why do we need clocks?

Accepted Answer

We need clocks to help keep track of time during the day. This helps us organize our activities like going to school, playing, or sleeping.

Question 16

What is a grandfather clock?

Accepted Answer

A grandfather clock is a tall, freestanding clock that usually has a pendulum. It often stands on the floor and makes a chiming sound.

Question 17

How did people know what time it was before clocks?

Accepted Answer

People looked at the position of the sun in the sky or used simple tools like sundials. They would also use the sound of church bells or wait until the sun rose and set.

Question 18

What is a sundial made of?

Accepted Answer

A sundial is usually made from a flat piece of stone or metal with a stick or pointer. The pointer casts a shadow on the marked surface to show the time.

Question 19

Why can’t sundials be used at night?

Accepted Answer

Sundials need sunlight to cast a shadow, so they can't work at night. People used other ways, like water clocks, to tell time in the dark.

Question 20

How do digital watches work?

Accepted Answer

Digital watches use tiny electronic parts inside to keep track of time. They show the time with numbers on a small screen.
