Over time, everybody gets older. This happens not

only to living things but also to buildings and cities.

What is modern now will be considered old in a

few years.

Every fact is located along the Timeline. We live in

the present, what has already happened is

considered the past and what will come is the

future.

We learn about the past studying fossils, for

example, but we can only imagine the future.

Present Future Past

1. Draw yourself in the square you have in the middle. Then something that happened in the past in the left square and imagine something that we will have in the future and draw it in the right square.

2. Here you have a Timeline. Using arrows () you must match the drawings with the line as in the example:

PAST PRESENT FUTURE

Present Future Past

ROADS In the past For thousands of years people travelled on land on

horseback, in carts pulled by oxen, or on foot.

There were no proper roads.

The Roman soldiers built good roads. All the roads they built were remarkably straight. The Romans knew that the shortest distance from one place to another is a straight line.

5

In the present Nowadays we have

good roads to

travel by car, bus,

motorbikes, etc

faster and more

comfortably.

3. How do you think roads will be in the future? Draw your idea.

ROADS IN THE FUTURE

4. Read and write:

A long time ago people travelled on land on _____________, in ________________, or ________________. Nowadays we have good roads to travel by _____________, ________________, _______________, etc.

MEANS OF TRANSPORT In the past As we have said, transports have changed along

the years. At the beginning, our ancestors used to go on foot until they found horses a useful transport.

Thanks to the

invention of the wheel, they could start using charts and carry many heavy things.

In the present Nowadays we have many different means of

transport. o If we want to go by land, we can use the bike,

the car or the train, for example.

7

o If we want to go by water, we can use the boat or the submarine.

o If we want to go by air, we can use the plane,

the helicopter, or even the rocket!

In the future We can have an idea of how transports will be. But

we still don’t know which fuel we will use: oil, hydrogen, sun, air?

5. How do you think transports will be in the future? Draw your idea.

TRANSPORTS IN THE FUTURE

6. Write the three ways we can travel nowadays and one example of each. _____________________ : _______________________

MEANS OF COMMUNICATION In the past How could people communicate with each other

without technology?

First was only the oral communication, telling stories. Our ancestors also used the paintings in caves. Indians sent messages with smoke signals too.

When the alphabet was invented and people could write, communication was easier. But not everybody knew how to write and read. That changed when the printing press was invented in 1440.

10

In the present Nowadays we have

many different means of communication. But most of them didn’t exist before the discovery of the electricity.

In the future Even with all that technology, we still write letters

and notes. What do you think we will use to communicate in the future? Will we still use pencils? 7. What kind of technology would you use to

communicate in the following cases:

If I want to communicate with my uncle who lives in Madrid I would use the ________________________________. If I want to communicate with an alien from another planet I would use the _______________________________.

THE GREATEST INVENTIONS

1. The printing press The German Johannes Gutenberg invented the printing press around 1440. Printing presses increased the speed with which book copies could be made, and that helped to spread knowledge.

2. The refrigerator The French Charles Tellier invented the refrigerator in 1876. It helps people to keep their food in good conditions, so they don’t need to go to the supermarket every day.

ELECTRICITY CIRCUITS

Learn about electricity circuits as you experiment with batteries, voltages and light bulbs. Try changing the battery in the circuit to make the light bulb glow brighter; increasing the voltage will have this effect. https://www.youtube.com/watch?v=VnnpLaKsqGU
