Science Primary 4 First Semester Language Support Teacher: Mark K. Viernes bones - hard, strong parts inside our body that give our body shape and keep us upright frame - something that gives support and shape from the inside hip - the bone that joins the leg to the upper part of the body jaw - the skull bone that moves when we eat or talk model - an object or drawing that helps us understand how something works or see what something looks like that we can't see in real life rib cage - the bones of the chest skeleton - the bones inside our body that are joined together to form a frame skull - the bones of the head spine - the bones of the back function - the job or use of something, for example the function of a pen is to write length - how long something is; for example, the length of a ruler is 30 cm muscles - parts of the body that are joined to bones and allow us to move organs - parts inside the body that do different jobs protect - keep safe from harm, for example, a jacket will protect you from the cold support - to hold up something so that it doesn't fall down contract - when muscles get shorter and fatter. Muscles feel hard when they contract. relax - when muscles get longer and thinner. Muscles feel soft when they relax. exoskeleton - the hard skins or shells on the outside of the bodies of some invertebrates identification key - a set of questions that allows us to name or group things invertebrate — an animal that has no backbone or spine  vertebrate - an animal that has a backbone or spine germs - very tiny living things that can cause diseases, for example we wash our hands before we eat so we don't get germs on our food infect - when the germs get into your body and make you ill infectious disease - a disease that is caused by germs instructions - information that tells us how to do something, for example Ali has a set of instructions to tell him how to build a model car medicines - substances that we use to help us get better when we are ill, for example cough mixture helps us to stop coughing prevent - to stop, for example a raincoat prevents us from getting wet when it rains vaccinations - injections or other medicines that stop us from getting a disease energy - anything that can cause movement or carry out an action. Refer to the notes in the introduction and remind learners that the term has a different meaning in Science to its meaning in everyday life predict - to say what you think will happen based on what you already know or have observed, for example we can predict that we will burn our hands if we touch a hot stove conclusion - what you have found out from an investigation energy transfer - when energy moves from one place to another place or from one object to another object destroy - to make something not exist anymore, for example to destroy a letter by burning it electric appliances - machines that use electrical energy to make them work, for example washing machines and kettles electrical energy - the form of energy we get from electricity carnivore - an animal that eats other animals consumer - a living thing that cannot make its own food and obtain energy by eating other living things, usually an animal that eats plants or other animals  food chain - a drawing that shows the order in which animals eat plants and other animals to get energy herbivore - an animal that eats plants omnivore - an animal that eats plants and other animals producer - a plant that makes its own food using energy from the Sun predator - an animal that kills and eats other animals prey - an animal that a predator kills and eats compare - to look at two or more things and say what is the same about them and what is different material - kinds of matter that we use, such glass and metal particle - a very small part or a bit of something substance - a particular type of solid, liquid or gas, for example, water pour - to make a liquid or other substance flow out of or into a container. For example, Atul pours water from the jug into a glass. property - what a substance or material is like, or the way it behaves. For example, a property of rock is that it is hard. A property of elasticity is that it can stretch. Another example of a property is a building or a piece of land. Explain that this is not the same as a property of a material. powder - a solid with fine grains that have air spaces between them, such as baby powder or flour. change of state - when materials and substances change from one form to another when they are heated or cooled melting - when a solid changes state to become a liquid physical process - when a substance changes form, e.g. melts, but does not become a new substance solidifying - when a liquid changes state to become a solid  chemical reaction - when we mix together two substances and they both change to make a new substance. For example, when we mix baking powder and water they both change to make carbon dioxide gas that makes a cake rise react-his is when a substance changes when it is mixed with another substance. For example, baking powder reacts with water to make carbon dioxide gas that makes a cake rise rust - a reddish-brown powder that forms on some metals
