Introduction Essential Science Plus 3 Teacher’s Resource Book provides a wide variety of photocopiable worksheets designed to complement Essential Science Plus 3 Student’s Book and Essential Science Plus 3 Teacher’s Book. These worksheets facilitate a flexible approach in the classroom. Students in the same class can be given different worksheets. Stronger students can expand on the material learnt in class. Weaker students can use the worksheets to revise. Alternatively, students can work together with stronger peers to complete the tasks. In addition, these worksheets can be photocopied and used for homework. There are five categories of worksheets: Reinforcement, Extension, Culture & Festivals, Investigate! and Assessment. Answer keys are provided at the back of this book.
Reinforcement and Extension worksheets There are twenty-four Reinforcement worksheets and twelve Extension worksheets. The Reinforcement worksheets are designed to provide additional support for students in need of further practice. They can be used after the relevant section in the Student’s Book, before the Show what you know sections, or as extra preparation for the Unit assessment. Depending on the students, they can complete the worksheets with or without consulting their Student’s Books, in the classroom or at home, individually or in pairs. The Extension worksheets can be used for fast finishers or to expand on the material covered in class. 1

Guide dogs act as eyes for people who are blind. They help blind people move from one place to another. They can help a blind person cross the road, avoid obstacles or go to the shops. Guide dogs stay with their owners at all times. Most guide dogs are Labradors or Golden Retrievers. They receive special training starting when they are puppies. Then, they are assigned to a blind person. Guide dogs wear a harness to do their job.

Broken bones Bones are hard, strong and rigid, but they can sometimes break or fracture. However, broken bones can repair themselves. There are many different types of fractures. The most common type is a simple fracture, which happens when a bone breaks cleanly. In order to help bones heal correctly, it is important that they are realigned. Broken bones can be put back into position by a doctor. The bones are then immobilised with a plaster cast, so they can start to heal. Simple fractures usually take about 6 to 8 weeks to heal, although large bones take longer.
1 Tick (✓) the true sentences and cross ( ✗ ) the false sentences. a. Bones break because they are rigid. b. Bones can repair themselves. c. The most common fracture is when a bone breaks into fragments. d. Broken bones need to be realigned before being immobilised. e. All fractures take about 6-8 weeks to heal. f. A fracture of the femur takes the same time to heal as a fracture of the radius.

Animal talk Animals do not talk like people, but they still communicate with each other. For example, birds sing and chirp, dogs bark, cats meow and lions roar. The blue whale is not only the largest animal on Earth, but also the loudest. Blue whales emit very loud and repetitive sounds that travel many kilometres underwater. The call of a blue whale can reach up to 188 decibels. This is much louder than a jet engine, which is about 140 decibels. Human shouting is 70 decibels. Sounds over 120 decibels are painful to our ears.
1 Read and write T (true) or F (false). Then, correct the false sentences. a. Blue whales are the largest and loudest animals on Earth. b. Their sounds can be heard from very far away. c.

The Venus flytrap The Venus flytrap is a small, carnivorous plant. Its sweet-scented leaves attract insects. These leaves open and close like jaws to capture insects. When the plant is touched, sensitive hairs on the inside of the leaves send signals to the plant. So, when an insect touches one of these hairs, the leaves snap shut. The plant then slowly digests the trapped insect. After about a week, all that is left of the insect is its hard exoskeleton. The Venus flytrap can live in soils with a low mineral content because it obtains minerals from the insects it captures.
1 Read and write True or False. Correct the false sentences. a. The Venus flytrap is a meat-eating plant. b. The plant’s beautiful flowers attract insects. c. Sensitive hairs digest the trapped insect. d. A Venus flytrap takes about a week to digest an insect.

Water, precious water About three quarters of our planet’s surface is covered with water. However, most of this water is salt water. Just a very small amount of water is fresh water. Most of this fresh water is trapped in ice caps and glaciers. It is also found in rivers, lakes and as groundwater. This means, there is very little water available for people to use. The world’s population has increased dramatically, and water consumption today is seven times higher than a hundred years ago. We need to save water and keep it free from pollution and contamination.

Sculpted landscapes Wind and water have shaped landscapes all over the Earth. No rock is hard enough to resist the forces of erosion. Wind is a powerful force that carries dust and sand from one place to another. It can carry huge amounts of dust over very long distances. It can also blow sand against rocks with tremendous force. This causes soft rocks to slowly wear down and sculpt amazing formations like arches, buttes and dunes. Moving water in rushing streams and rivers is the major agent of water erosion. Ocean water changes the shape of coastlines. Waves constantly crash against cliffs forming arches, caves and columns. Rain slowly washes away soil and rock fragments creating ever-changing landscapes.
1 Match the rock formations to their definitions. a. cave
a vertical rock formation
b. arch
a hill that rises sharply and has a flat top
c. butte
an underground hollow with an opening to the outside
d. dune
a curved rock formation
e. column

The Grand Canyon The Grand Canyon, Arizona, is situated on the Colorado Plateau, a high plateau with a very dry climate. Today, the Grand Canyon is a famous national park with an impressive skywalk, 1,300 metres above the canyon floor. Over a period of about ten million years, the Colorado River cut deeper and deeper through many layers of rock to form the Grand Canyon. Wind erosion was also important in creating this landscape. The canyon is about 446 kilometres long, more than 1,800 metres deep at the deepest part, and up to 29 kilometres wide in some areas. The Grand Canyon is home to many different kinds of fauna, including 70 species of mammals, 25 species of fish, 250 species of birds and 25 species of reptiles.

Weather satellites Nowadays, weather satellites collect complete weather information about every place on Earth. They provide satellite images and other useful data about the atmosphere. There are two types of weather satellites: polar orbiting and geostationary. Polar orbiting satellites go around the planet from the North Pole to the South Pole, and are able to view every part of the Earth twice a day! They travel close to the Earth’s surface, as low as 800 km, and provide extremely detailed satellite pictures of weather patterns around the planet. Geostationary satellites track the weather over one specific region by staying over the same place. They orbit the planet at 36,000 km above the Equator. Weather satellites collect more than just information about the weather. They can also tell us about forest fires, volcanoes, dust storms and other environmental phenomena.

Villages, towns and cities over time Many villages, towns and cities in Spain are thousands of years old and they have changed completely since their origins. Over a period of hundreds of years, some small villages grew into towns and some of the towns became big cities with large populations, tall buildings, wide streets and many industries and services. Three quarters of the population of Spain now lives in towns and cities. However, only two cities, Madrid and Barcelona, have a population of more than one million inhabitants, and only four other cities, Valencia, Seville, Zaragoza and Malaga, have a population of over 500,000 inhabitants. However, not all villages have grown. Some are almost abandoned these days, with few inhabitants left, due to rural migration. The villagers have moved away to the cities in search of jobs, education and better opportunities.

Where does paper come from? Paper was invented in China over 2,000 years ago. Originally, paper was made of pulp produced by boiling cloth and old fishing nets! Nowadays, paper is made of pulp from wood. Large plantations of trees are grown. The trees are cut down, then chopped into small wood chips. These chips are soaked in water and chemicals to form wood pulp. The pulp is bleached to remove tree bark and sap. Next, the pulp is drained and squeezed to remove all the excess water, then placed in huge drying machines. The pulp is then attached to spools and placed in cutting machines. Lots of different paper products are made these days from recycled paper. Using recycled paper to make new paper has a less negative impact on the environment, and is better for the planet. Recycled paper is used for everything from paper plates to toilet paper!

Groundhog Day Groundhog Day is a holiday celebrated each year on the 2nd February in the United States of America and Canada. In the States, thousands of people go to Punxsutawney, Pennsylvania, to see this event. On this date, a special groundhog, called Phil, comes out of his burrow after hibernating all winter. Groundhog Phil makes predictions about the weather for the rest of the winter. According to tradition, if it is sunny on the 2nd February and the groundhog sees its shadow, it returns to its burrow. This means that winter weather will continue for six more weeks. If it is cloudy and the groundhog doesn’t see its shadow, it means that spring weather will arrive soon. On the 2nd February 2012, Groundhog Phil saw his shadow and predicted six more weeks of winter.

Name The Chinese calendar The Chinese calendar is based on the phases of the Moon. The Chinese New Year is not always on the same date: it begins between the end of January and the middle of February. The Chinese calendar follows a 12-year pattern. Each year is named after an animal. According to legend, Buddha invited all of the animals to join him for a New Year’s celebration, but only 12 animals appeared. To reward these animals, Buddha named a year after each animal to arrive. The first year was the year of the Rat. The second year was the Year of the Ox. This was followed by the Year of the Tiger, and the years of the Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog and finally, the Pig. According to Chinese tradition, people have the characteristics of the animal of the year they were born.
1 Look on the Internet to find the animal of this year’s Chinese calendar. Find and write a list of this animal’s characteristics.
2 Look at the calendar. Which year were you born? Which animal represents that year? Find out and write the characteristics you share with this animal.

Name Tsunamis Tsunamis are usually caused by underwater earthquakes which move a huge volume of water. As a result, a very long, but not very tall wave is produced. The wave spreads across the sea in all directions, and travels long distances at the speed of an aeroplane.
Most tsunamis happen in the Pacific Ocean, and they can cross the entire ocean in less than a day! When a tsunami approaches the coast and reaches shallow water, the wave slows down. The top of the wave moves faster than the bottom. The wave rises up to several hundred metres and destroys everything in its path. An approaching tsunami sounds like a train! In 2011, a massive tsunami hit the northeast coast of Japan. It originated from a big earthquake 400 kilometres away. Some of the tsunami waves grew to 40 metres high. Over 15,000 people were killed and the damage was devastating.
1 Tick (✓) the true sentences and cross ( ✗) the false sentences. a. Tsunamis originate in the water. b. The first wave is very long and very tall. c. Tsunamis are caused by the tides. d. They are most common in the Pacific Ocean. e. Tsunami waves reach up to several hundred metres at the coast. f. Tsunami waves make a lot of noise.

Name A unique ‘sea’ The Dead Sea is really a salt lake. It is located in the Middle East, between Jordan and Israel. It is called a ‘sea’ because the water is so salty. And it is called ‘dead’ because fish and plants cannot live in it due to its high salt and mineral content.
The Dead Sea is 420 metres below sea level, and it is considered the lowest point on the planet. In fact, its salt content is due to its location. Being the lowest point on Earth, minerals have been flowing into it for millions of years, making the Dead Sea nearly nine times saltier than the oceans. This high concentration of salt allows people to float in it without using a life jacket. You can even read a book while you float on the water!
1 Circle the correct words. a. The Dead Sea is a salt water / fresh water lake. b. Fish and plants can live / cannot live in the Dead Sea. c. The Dead Sea is located above / below sea level. d. Its high salt content is because of its temperature / location. e. Floating in the Dead Sea is easier / harder than floating in the ocean.
2 Search the Internet for information about the Great Salt Lake in Utah, United States. Write some sentences about the lake.

Hurricanes, the power of wind Hurricanes are huge, swirling storms that form over warm oceans, near the Equator. They bring extremely strong, rotating winds and heavy rain. In the strongest hurricanes, known as ‘category 5’ hurricanes, winds can reach more than 300 kilometres per hour. Hurricanes spin in an anticlockwise direction around a central ‘eye’, which is the calmest part of the storm. They can be up to 800 kilometres in diameter. Hurricanes concentrate in the Atlantic Ocean and the eastern Pacific Ocean. The Atlantic hurricane season goes from the end of May to the end of November, but most hurricanes occur during the autumn months. On the 29th of August 2005, Hurricane Katrina hit the city of New Orleans in the United States. It was one of the most powerful hurricanes ever recorded in history. It caused many deaths, as well as catastrophic damage.

The Olympic Games The Summer Olympic Games is the largest sporting event in the world. It is held every four years, each time in a different country. The Olympic Games is a celebration of excellence, respect and friendship. The symbol of the Olympics is five interlocking rings (black, blue, yellow, green and red) on a white background. They represent the five continents of the world. The Olympic Torch is lit in Olympia, in Greece, where the Olympic Games originated. The torch is then carried around the world by athletes, until it reaches the host city on the opening night of the Games. It is a great honour to run with the torch and pass it on to the next runner. Over the years, the torch has also been carried by boat, on an aeroplane, on a camel, and even by laser beam! The Olympic Games provides thousands of jobs from building or updating sports facilities and city infrastructures, to providing services for the many visitors attending this major sports event.
1 Answer the questions. a. What type of event is the Olympic Games? b. How often does it take place? c. Where did the Olympic Games originate?

Some people wear a shamrock, a three leaf clover, which is an Irish symbol representing the rebirth of spring. Many cities organise Saint Patrick’s Day Parades. In Dublin, famous buildings are lit up green during the festivities. Other cities paint the yellow street lines green for the day. In Chicago, in the United States, the Chicago River is dyed green on Saint Patrick’s Day!
