FOREWORD This is a pivotal time in the history of the Ministry of Education and Technical Education (MOETE) in Egypt. We are embarking on the transformation of Egypt’s K-12 education system starting in September 2018 with KG1, KG2 and Primary 1 continuing to be rolled out year after year until 2030. We are transforming the way in which students learn to prepare Egypt’s youth to succeed in a future world that we cannot entirely imagine. MOETE is very proud to present this new series of textbooks, Discover, with the accompanying digital learning materials that captures its vision of the transformation journey. This is the result of much consultation, much thought and a lot of work. We have drawn on the best expertise and experience from national and international organizations and education professionals to support us in translating our vision into an innovative national curriculum framework and exciting and inspiring print and digital learning materials. The MOETE extends its deep appreciation to its own “Central Administration for Curriculum Development” (CACD) and “Discovery Education”. This transformation of Egypt’s education system would not have been possible without the significant support of Egypt’s current president, His Excellency President Abdel Fattah El-Sisi. Overhauling the education system is part of the president’s vision of ‘rebuilding the Egyptian citizen’ and it is closely coordinated with the ministries of higher education & scientific research, Culture, and Youth & Sports. Education 2.0 is only a part in a bigger national effort to propel Egypt to the ranks of developed countries and to ensure a great future to all of its citizens.

FOREWORD The MOETE launched Egypt’s reform vision for the development of education, and the process of developing curricula comes at the heart of this vision. The implementation of this vision was heralded in 2018, starting with the kindergarten stage in its first and second grades, with the aim of continuing until the end of the secondary stage. This vision endeavored to make major transformations in the teaching and learning processes, where there is a transition from acquiring knowledge to producing it, and from learning skills to employing them both in specific learning situations and in the general life of the learner outside the classroom. Our curricula also integrate values that contribute to the establishment of our society—values which pose as a protective fort for our homeland. Egypt’s reform vision for curriculum development also aims to take into account the specifications of pre-university education graduates, as well as the challenges Egypt faces locally, regionally, and globally. The developed curricula are intended to foster a citizen who is capable of engaging in civilized conversations and positive dialogues with the other, in addition to acquiring digital citizenship skills. In this regard, the MOETE extends its gratitude and appreciation to the Central Administration for the Development of Curricula and Educational Materials. It also extends its thanks and gratitude to Discovery Education for their active participation in the preparation of this book. Gratefulness also goes to all the Ministry’s experts who contributed to the enrichment of this work. This transformation of Egypt’s education system would not have been possible without the significant support of Egypt’s current president, His Excellency President Abdel Fattah el-Sisi. Overhauling the education system is part of the President’s vision of “rebuilding the Egyptian citizen” and it is closely coordinated with the Ministries of Higher Education and Scientific Research, Culture, and Youth and Sports.

Lesson 1 Activity 3 Observe Like a Scientist Adaptations for Survival Scientists ask a lot of questions. When scientists learn something new, new questions come to mind. Read the text about another type of adaptation that helps animals survive. Then, write two questions you have. Adaptations for Survival Adaptations are characteristics that help living organisms survive and reproduce in the ecosystem in which they live. For example, thick, white fur is an adaptation in polar bears. It helps them stay warm in their cold, Arctic home. It also helps polar bears blend in with the snow as they sneak up on their prey. In contrast, many bears that live in other habitats have darker fur. Brown bears and black bears live in forests. Their dark fur helps them stay hidden among the trees as they hunt. Sandy-colored fur helps desert animals, such as caracals and fennec foxes, blend in with desert landscapes. Rocks in the desert can also be quite colorful. Many lizards have colorful scales that make them hard to see among the rocks. This type of adaptation that hides animals from a predator or their prey is called camouflage. Can the fur on some animals change color with different seasons? What prey do polar bears need to sneak up on? Write other questions. I wonder . . .

Lesson 2 1.1 Learn How do different types of animals and plants adapt to survive extreme climates? Activity 4 Analyze Like a Scientist Types of Adaptations Animals can be found from the coldest polar regions to the hottest deserts and the deepest oceans on our planet. An adaptation is a characteristic of an animal that helps the animal survive.

Read the text that follows, think about both the structural and behavioral adaptations described. Circle behavioral adaptations and underline the structural adaptations you find in the passages. Fennec foxes and Arctic foxes both live in extreme climates. Fennec foxes have a tan-colored coat that provides camouflage in a sandy, rocky environment and protects them from the scorching hot sun. Fennec foxes, like dogs, also cool themselves by panting, taking up to 700 breaths per minute. Arctic foxes live in a different type of desert, a tundra. With temperatures as cold as 50 degree below zero (50º).C in the winter months, a thick fur coat helps them hunt even in deep snow. This coat is white during the winter but turns brown in summer when the snow melts, so they can sneak up on prey in any season. Extra-large ears allow heat to escape to cool fennec foxes, while short ears and legs help the Arctic fox stay warm. Both types of foxes also live in burrows. A burrow is an excellent place for the Arctic fox to stay warm at night and the fennec fox to stay cool during the day. Food can be hard to find at times in both the hot, dry desert and the cold tundra. Both foxes have learned to eat all kinds of food, including insects, fruit, plant roots, and even leftovers from another animal’s prey. Animals that are flexible about what they eat and where they hunt are well-adapted for survival. Bull sharks are special because they can survive in both salt water and fresh water, unlike other sharks.

How long were you able to stay under without coming up for air? Now imagine that you were a fish and could breathe under the water but not on land. How would your respiratory system need to be different? Read the text that follows to learn about how fish have adapted to life underwater. Unlike humans, fish do not breathe using lungs. Fish use gills to take oxygen that dissolved in water out and release carbon dioxide. Gills are found on the sides of a fish's head. Water enters the mouth of the fish and passes across the gills. Just like in our lungs, blood vessels then carry oxygen to the rest of the body. Gills are unique structural adaptations that allow fish to live and breathe underwater. How do you think water pollution impacts the fish that live nearby? Just as we need to breathe clean air to stay healthy, fish need clean water to survive.

Lesson 1 1.3 Wonder What needs to happen for humans or other animals to see an object in low-light areas? Activity 2 Ask Questions Like a Scientist Hunting with Night Vision You thought about how difficult it is to see when there is not much light. Consider other animals. Do you know of any animals that can see in the dark? Read the text. Then, discuss what you notice about how your own vision works at night, record your question. We use our sense of sight to gather information about what is happening around us. To see well, our eyes require light. Without light, we would need a set of night vision goggles to see in the dark. This is not true for all animals though. The fishing cat is a wild cat that hunts for food at night. These animals are able to find their prey in the dark because of the structure of their eyes. The fishing cat’s eyes seem to glow in the dark. The reason they do this is because all cats have a mirror-like membrane on the back of their eyes. As light enters, it bounces off this membrane, allowing the eye to collect more available light. This adaptation (structural adaptation) allows cats to have excellent night vision that they use to hunt successfully in the dark. Humans have difficulty seeing in the dark, but nocturnal animals are better able to see. Why is this so? Many nocturnal animals have spectacular night vision. As you read in the Investigative Phenomenon, some animals have eyes that are different than ours. There are many differences between the eyes of a human and a nocturnal animal. To start, nocturnal animals have bigger eyes than humans.

Logan learns that the people who work to preserve the monument check the stone for cracks. The faces at Mount Rushmore are carved into a kind of rock called granite. Water can seep into cracks in the rock. During cold weather, the water freezes into ice. As ice becomes solid, it expands, or gets a little bigger. Ice inside cracks in rock pushes the granite apart little by little. The cracks can get bigger. Over time, small cracks could cause large chunks of rock to break off and fall. This happens to carved stones and to natural rock, too. Water gets into a crack. Ice gets bigger and pushes the crack wider. The rock can break.

Glaciers shaped the land in Glacier National Park. They also helped form its water features. Many glaciers melt a little in the summer. Water flows out from them. It flows into streams, rivers, and lakes. Some glaciers melt completely over time. When this happens, the hollow shape of the glacier is left behind. It fills with water, and a lake is formed. Sliding glaciers can grind rock into a fine powder. The powder mixes with water in lakes. It can make them appear blue or green.

But the sound of the ball helps players tell when it is coming. The sound helps players tell which direction the ball is coming from. Your ability to detect sound is your sense of hearing. Hearing helps you detect objects that are in motion around you. For example, you hear footsteps moving toward or away from you. You hear the rustle of the clothes of a nearby person. You hear the engine of an approaching car or one that is moving away from you. Hearing also helps you to communicate. You listen to others speak. You hear the words people say.

Parts of the Ear The human body part that enables hearing is the ear. The part of the ear that you can see is shaped something like a funnel. The outer ear and ear canal focus sound waves into the inside of the ear. The parts of the ear that sense vibration are inside the ear. You cannot see these parts. Vibrating air pushes against a thin piece of tissue called the eardrum. The eardrum vibrates an arrangement of three tiny bones. The tiny bones pass the vibrations through the cochlea to the auditory nerve. Nerves deliver the message to the brain. Word to Know Auditory refers to things related to hearing.

Parts of the Eye The human body part that enables vision is the eye. The colored part of the eye is the iris. The pupil looks like a black circle in the center of the iris. The pupil is an opening in the eye. Light passes through the pupil to the inside of the eye. The pupil can get larger or smaller. In bright light, the pupil closes to become smaller. In dim light, the pupil opens up. When the pupil is open larger, more light gets into the eye. When the pupil is closed smaller, less light gets into the eye. The clear front surface of the eye is the cornea. Light passes through the cornea. The lens is also transparent. It is located inside the pupil. The lens focuses light inside the eye.

Many of the cities in Mesopotamia were built with walls around them for protection. This is what a walled city would have looked like long ago. People had many different kinds of jobs in the cities of Mesopotamia. Some people, called craftsmen, made pots, baskets, clothes, and jewelry. Others carried people by boat from place to place.

CHAPTER 3 City Life in Ancient Mesopotamia Some people in Mesopotamia knew how to read and write. They didn’t write on paper. Instead they used reeds to make marks on wet clay. This way of writing is called cuneiform. Having a way to write down important information helped make the Mesopotamian civilization great.

What Latitude Tells You In general, the closer you are to the equator, the warmer the climate is. So, places at low latitude are usually warm year-round. Places located at a high latitude are usually colder. That is true both north and south of the equator. The North and South Poles, at 90°N and 90°S, are cold all year. Most of the United States lies between 25° N and 47° N. Miami, Florida is located at about 25° N. The weather in Miami is usually warm. Even in the winter, it is often warm enough to wear shorts. Detroit, Michigan, is located at about 42° N. What do you think the winters are like in that city? Winters in Detroit are cold! Often, the Detroit River freezes over as ice forms on the surface. The city also gets lots of snow and several months of freezing weather. Fairbanks, Alaska, is located at 64° N. Honolulu, Hawaii, is located at 21° N. How do you think the January temperatures in Fairbanks and Honolulu compare? Now look south of the equator. The tip of South America reaches to about 55° S. It’s almost as far south of the equator as Alaska is north. The climate there is cold all year long. Farther north in South America, the weather becomes warmer. The city of Recife, Brazil, is located at about 8° S. Recife is warmer than Miami. This is because it is so much closer to the equator. When you visited the captain, he told you the ship was at 1° N. By now, you probably have a good idea what the temperature is likely to be there.

Parallels of latitude also help us name parts of the globe. The equator divides Earth into two hemispheres (/hem*uh*sfeerz/). A hemisphere is half of a sphere or ball.

What are natural hazards ... and disasters? Forces of nature that happen with little warning and occur all over the world, such as earthquakes, tsunamis, floods, landslides, tropical cyclones (and other storms), storm surges, heatwaves, wildfires, droughts and volcanic eruptions. When these natural hazards pose a threat to humans or the environment they can lead to disasters, and cause destruction in a community. What are volcanoes? A volcano is an opening in the Earth's crust that allows magma, volcanic ash and gases to escape. Magma is rock so hot that it is molten, and liquid. When the magma reaches the surface of the Earth it is called lava, and pours out of the volcano, along with the gases and ash. Volcanic eruptions can be dangerous and deadly, producing pyroclastic flows, volcanic bombs and ash clouds. They can also trigger earthquakes, tsunamis, mudslides and lahars. The World Meteorological Organization and its partners help countries to prepare for and respond to volcanic eruptions. COPE will teach you how to be ready for volcanic eruptions!
