Early Modern Age
The Early Modern Age began in 1492 with Columbus' discovery of America and ended with the French Revolution in 1789. Society was divided into clergy, nobles, and commoners. Fernando and Isabel, known as the Catholic Monarchs, united Castilla and Aragón, supported Columbus' voyage, conquered Granada, and established the Spanish Inquisition. The Age of Discovery saw many explorers like Columbus, Magellan, Pizarro, and Cortés discover and conquer new lands. In the 16th-17th centuries, the Hapsburg dynasty ruled Spain and its vast global empire. During this Golden Age, artists like El Greco, Velázquez, and Murillo and writers like Cerv
Electricity and inventions
Electricity is a form of energy that is created by the movement of electrons between atoms. In the 18th century scientists began studying electricity which led to many inventions in the 19th and 20th centuries, including those of Thomas Edison such as the electric light bulb. Electricity powers our modern world through electrical circuits which can be simple, series, or parallel and get energy from power stations to homes through cables and fuse boxes.
Unit 5 - Heat and Light
Thermal energy and light are different forms of energy that can be transferred and transformed. Thermal energy is the total kinetic energy of particles in an object and causes temperature, while light is a type of electromagnetic radiation. Thermal energy can be transferred through conduction, convection, or radiation between objects and drive processes like chemical reactions, phase changes, and expansion. Light can travel through transparent, translucent, or be blocked by opaque materials and is reflected by mirrors and refracted when changing mediums. When light is absorbed by an object, it is transformed into thermal energy.
Unit 5 Social Science
During the Middle Ages in Spain:
- The Iberian Peninsula was divided between several Christian kingdoms in the north and a large Muslim state called al-Andalus in the south, after Muslim armies conquered the region in the 8th century.
- Al-Andalus had a highly developed culture and economy but was eventually reconquered by the expanding Christian kingdoms between the 8th-15th centuries in a process known as the Reconquista.
- By 1492, the Christian conquest was completed when Granada fell and the Muslims were expelled from the Iberian Peninsula.
Electricity and inventions
Electricity is formed by the movement of electrons between atoms. In the 18th century scientists began studying electricity which led to many inventions in the 19th and 20th centuries. Thomas Edison discovered ways to produce and use electricity commercially and invented devices like the light bulb which changed modern life. Electricity is transmitted through power lines from generation stations to homes where it powers devices through electrical circuits.
NS5 Unit 4 - Energy
Energy can be mechanical, chemical, electrical, thermal, light, or nuclear. Mechanical energy includes kinetic and potential energy. Chemical energy is stored in substances, electrical energy is in the form of electricity, and thermal energy is heat. Common energy transformations include fuel in cars becoming kinetic and thermal energy and electrical energy powering fans and becoming kinetic and thermal energy. Renewable energy sources include hydroelectric, wind, solar, and biofuels while non-renewable sources are petroleum, coal, uranium, and natural gas.
Unit 4 - Money and business
This document discusses various topics related to money, business, and economics. It explains that money is used to purchase goods and services, and was historically represented by objects like grains or shells. It also discusses ways to save money such as using money boxes, savings accounts, or investing. Businesses are organized in different structures like sole traders, partnerships, corporations, or cooperatives. Budgets help control spending, and money can be spent in various locations or on different types of products.
Unit 3 Tertiary sector
The document discusses the tertiary sector of the economy. The tertiary sector consists of activities that provide services to consumers and businesses. It is divided into different areas like health, education, public safety, administration, cultural professions, and the judicial system. Within the tertiary sector, there are also several types of transport like air, water, rail, and road transport. Various types of retail businesses that sell goods to consumers are also part of the tertiary sector, including hypermarkets, supermarkets, department stores, and specialty shops. The tertiary sector is particularly important in Spain, where more people work in services than in the primary and secondary sectors combined.
Unit 2 - The classification of living things
1) Living things are classified into kingdoms, including Animal, Plant, Monera, Fungi and Protista.
2) Within the Animal kingdom, vertebrates like mammals, fish, birds, reptiles and amphibians have backbones, while invertebrates like worms and snails do not.
3) Each type of animal has distinguishing characteristics - mammals have hair and breathe with lungs, reptiles have scales and breathe with lungs, fish breathe with gills and have fins/scales, birds fly and lay eggs, amphibians have thin skin and go through metamorphosis.
The economy
The document discusses the economy and its three sectors: the primary, secondary, and tertiary sectors. The primary sector involves extracting raw materials from nature through activities like agriculture, forestry, fishing, and mining. The secondary sector processes and manufactures raw materials into products using factories and workshops. The tertiary sector provides services. Within the primary sector, the document outlines the different types of agriculture (arable and livestock farming), fishing, forestry, and mining. It also discusses the intermediate and consumer products produced in the secondary sector and how factories are powered.
The organisation of living things
Living things are organized from cells to systems. Cells make up tissues, tissues make up organs, and organs work together in systems to carry out the basic life processes of interaction, reproduction and nutrition. There are differences between plant and animal cells, such as plant cells having a cell wall and vacuoles, but generally cells are the basic unit of structure and function for all living things.
Unit 1 Social Science
Demography is the study of how and why populations change over time. Populations change through births, deaths, and migration. Pyramid graphs can represent population distribution by age and gender, and show patterns of population growth. Populations can be divided into groups based on factors like gender, age, ethnicity, religion, and more.
Unit 3 Natural Science
An ecosystem includes both living and non-living components. It is composed of a biotope, the non-living elements like climate and soil, and a biocoenosis, the living elements. Organisms have trophic relationships where some eat others in a food chain. Ecosystems can be classified by type like prairie or pond. The biosphere is the largest biome and includes all Earth's ecosystems. Ecosystems change naturally through seasonal variations but also due to human activities like pollution, overfishing, forest fires, and deforestation which can destroy habitats.

Unit 2 Natural Sciences
Living things are classified into five kingdoms: Animal, Plant, Monera, Fungi and Protista. The Animal kingdom contains vertebrates like mammals, fish, birds, reptiles and amphibians, as well as invertebrates like worms and snails. Mammals are distinguished by having lungs, skin, hair and usually four legs. Reptiles have hard scales, lungs, and many have four legs though snakes do not, and they lay eggs. Fish breathe with gills, have scales and fins/tails, and lay eggs. Birds have lungs, wings, legs and aerodynamic bodies and lay eggs. Amphibians have thin skin, four legs, gills as young
Unit 1 Natural Sciences
Living things can be categorized into different levels of organization from cells to tissues to organs to systems. Cells are the basic unit of structure and function, and while all cells share basic characteristics, cells also specialize to carry out different functions. The organization of cells into tissues, organs and systems allows animals and plants to effectively interact with their environments and carry out the essential life processes of nutrition, respiration and reproduction.
