Preface
New Science is written in accordance with the 2024 Science (Primary 1–6) Curriculum Framework 6) Curriculum Framework . This series encourages pupils to explore with curiosity and learn through applying. It aims at nurturing pupils’ curiosity and interest in science, helping them acquire basic scientific knowledge, and cultivating their creativity and innovative thinking to better prepare them for the future. It features: 1 A systematic course structure This series organises the essential learning content stated in the curriculum framework into different units. It allows pupils to gradually build basic scientific knowledge and skills of the four learning strands across grades, develop science inquiry and problem-solving skills, learn about innovative technology, and develop preliminary engineering thinking and practical skills. 2 A close connection with pupils’ daily life experiences This series, supplemented by learning experiences outside the classroom, aims to cater for the needs and interests of pupils. It also lets pupils understand the application of science and technology in daily life in an interesting, life-oriented and diversified way, allowing them to apply their scientific knowledge to solving real-life problems. 3 Inquiry and problem-solving skills Inquiry is the process of seeking out problems and solutions. Through scientific questions and inquiry activities in the textbook, supplemented by the Scientific Inquiry Activity Booklet , this series encourages pupils to apply different scientific methods to finding solutions to problems through hands-on and minds-on activities, and cultivates evidence-based scientific thinking. 4 Values education This series enables pupils to realise that science and technology can improve people’s quality of life, and people mastering science can bring about positive changes to society, and contribute to our nation and Hong Kong. In the process of science inquiry, pupils can learn from the perseverance of scientists and experts in truth-seeking, innovation and continuous experimentation. Moreover, a learning partner named ‘Little Mentor’ is included in some units to help pupils cultivate positive values and attitudes. The ‘Back to the Past’ section allows pupils to learn about the past and present development and application of science and technology in the nation, thus enhancing their sense of national identity and national confidence. 5 Cross-curricular learning This series emphasises the collaboration between Primary Science and Primary Humanities. It features ‘Humanities Link-up’ to connect the content of the two subjects. Moreover, it includes diversified STEAM activities to let pupils apply the knowledge and skills acquired in Mathematics and Computer Studies to solving real-life problems by designing and making different models or products. Each book also features thematic reading materials so that pupils can apply the reading skills they learned from language classes in reading passages related to scientific knowledge, celebrities, and information about Hong Kong, the nation and the world. This helps broaden their horizons. 6 Self-directed learning Lead-in questions on the unit cover of every unit ignite pupils’ curiosity and interest in exploring science. Sections such as ‘Life Link’ and ‘More to Explore’ encourage pupils to explore the topic and learn beyond the classroom to achieve life-wide learning. Each unit also features a ‘Self-assessment’ section for pupils to evaluate their learning performance and reflect on more topics to explore, so as to develop their self-directed learning capabilities. Additionally, the subject website provides a wealth of learning and teaching resources to enrich pupils’ learning. (*The resources have not been reviewed by the Education Bureau.)

Community
Dogs can keep us company. They can also be therapy dogs and visit patients in hospitals, making them happy.
Trained dogs can be guide dogs, helping visually impaired people walk safely in public areas.
Nature
Bees and butterflies transport pollen. Earthworms make the soil loose. They all help plants grow. With their help, we can see many beautiful plants.
Let’s Think
1. Do you agree that dogs are man’s best friends? Why or why not? 2. Which animals help plants grow?

The Earth’s Jacket — The Atmosphere
香港資訊 Science for You
The atmosphere surrounds the surface of the Earth. Do you know how thick the atmosphere is? Scientists divide the atmosphere into five layers based on their temperatures. Different layers have different features.
Artificial satellites work in this layer. The fifth layer
The fourth layer Air is very thin, but it can block the harmful things from sunlight. Astronauts live in this layer.
The third layer Air is thin and cold.
The second layer Planes usually fly in this layer.
The first layer It is the closest layer to the ground. Humans, animals and plants live in this layer. There are different weather conditions, such as clouds and rain, here.
Let’s Think
1. Which layer do we live in? 2. Which layer of the atmosphere do birds fly in? What about planes?
