Science Skills – Grade 6

TERM 1 UNIT 1: THE ENVIRONMENT18 In this Unit, students will learn about climate change, its effects and ways of stemming it. They will explore the nature of solid waste pollution, and identify ways in which this problem can be alleviated. In addition, they will study the causes of soil degradation, the methods of preventing soil degradation, and appreciate the importance of caring for the environment.

TERM 1 UNIT 2: LIGHT AND SOUND7 In this unit, students will investigate the nature of light and sound energy, and how they interact with various materials. They will identify sources of noise pollution, note the harmful effects on humans and be aware of mitigation strategies.

TERM 2 UNIT 2: HUMAN BODY SYSTEMS3 In this Unit, students will learn about selected human body systems. Through observations, demonstration and research they will identify the organs associated with each system and state their functions. Range of Content • The main structures and functions of selected human body systems  Circulatory system (Heart, blood, blood vessels). The main job of the circulatory system is the transporting materials throughout the body. It carries nutrients, oxygen and water to different parts of the body and removes waste.  Digestive system (mouth, oesophagus, stomach, small intestine, large intestine). The digestive system helps to break down food into a form that the body can find useful.  Excretory system (kidney, bladder, skin, lungs). Substances that may be harmful to the body are removed through the excretory system.  Nervous system (brain, spinal cord, nerves). The nervous system controls the body's actions.  Reproductive system (penis, testes, vagina, ovary, uterus/womb). The reproductive system is responsible for producing offspring.  Respiratory system (nose, trachea, lungs). The respiratory system produces energy from food.  Skeletal and muscular systems (muscles, bones, joints). The muscular and skeletal systems work together to help the body to move. The skeletal system also protects major organs throughout the body.

TERM 2 UNIT 1: MATERIALS PROPERTIES AND USES1 In this unit, students continue to learn about the names, properties and uses of everyday materials begun at the lower grades, are clear about safety at all times, and recognise that materials are handled, stored and disposed of in different ways depending on their properties. Students will plan investigations; including controlling variables where appropriate e.g. fair tests. Students will differentiate between reversible and irreversible changes. They will evaluate, through investigations, whether or not particular changes are reversible. They will assess the usefulness of some reversible and irreversible changes in everyday situations.

TERM 2 UNIT 3: MIXTURES1 In this unit, students will learn that substances can be combined to form mixtures. They will classify mixtures according to their properties. They will learn to work cooperatively and develop problem solving skills as they investigate specific methods of separating mixtures. Range of Content • Substances combine to form mixtures • Types of mixtures include solutions, suspensions, and colloids • Mixtures can be physically separated based on size of particles, magnetic properties and how readily they dissolve • Methods of separating mixtures include filtration, evaporation, sieving, and decanting
