Cambridge Primary Sample Test For use with curriculum published in September 2020 Science Paper Stage 35 minutes Name No additional materials are needed INSTRUCTIONS • Answer all questions • Write your answer to each question in the space provided • You should show all your working on the question paper INFORMATION • The total mark for this paper is 40 • The number of marks for each question or part question is shown in brackets [ ] Science_S6_01/7RP © UCLES 2020 The diagram is a model of the human circulatory system The arrows show the direction of blood flow through the heart and blood vessels lungs blood vessel A blood vessel B blood vessel C blood vessel D heart body parts (a) What is the function of the heart? [1] pump the blood to all body part (b) What is the name of the type of blood vessels labelled A and C? [1] Arteries © UCLES 2020 S/S6/01 (c) What is the name of the type of blood vessels labelled B and D? [1] veins (d) The blood circulatory system in humans is called a double circulatory system Use the arrows on the diagram to suggest why In one circulation, the blood vessels bring blood without oxygen to the lungs and return to the heart In other circulation, the blood vessels bring blood with oxygen and food to body parts and return the heart [1] (e) Write down one function of the blood in the circulatory system [1] Blood caries food and oxygen Because it has two separate circuits and blood passes through the heart twice: - the pulmonary circuit is between the heart and lungs - the systemic circuit is between the heart and the other organs © UCLES 2020 S/S6/01 [Turn over Look at the table of properties of some substances boiling point in oC 58 electrical conductivity low 1085 2562 high iron 1540 2862 high mercury −39 357 high oxygen −218 −183 low silver 961 2162 high substance melting point in oC bromine −7 copper (a) Which change of state happens to oxygen when it boils? [1] evaporating (b) What is the meaning of the words boiling point? Bolling point mean when the liquid at that temperature, it will boil [1] (c) Melting point, boiling point and electrical conductivity are all properties of a substance Write down one other property of a substance [1] freezing point (d) Room temperature is 25 °C Bromine is a liquid at room temperature Complete the sentence to explain why Bromine has a melting point than room lower temperature and a boiling point higher than room temperature [1] © UCLES 2020 S/S6/01 Blessy uses a periscope to look over a wall at a light source (a) Look at the diagram The periscope has two plane mirrors A ray of light enters the periscope and finally enters Blessy’s eye Complete the path of the ray of light on the diagram until the ray of light reaches Blessy’s eye plane mirror ray of light light source periscope wall Blessy’s eye plane mirror [3] (b) Name the process that happens when the ray of light hits the plane mirrors [1] reflection © UCLES 2020 S/S6/01 [Turn over The diagram shows a simple rock cycle sedimentary process B process A process C igneous metamorphic process E process D process F magma Look at the table It shows descriptions of some of the processes in the rock cycle Complete the table process description A erosion and sedimentation B heat and pressure C weathering and erosion D melting E melting F cooling [4] © UCLES 2020 S/S6/01 Priya and Rajiv are visiting this rainforest Priya and Rajiv are worried they may be bitten by an insect and get an infection (a) Describe two ways Priya and Rajiv can avoid being bitten by insects in the rainforest To wear full clothes To spray mosquito repellent [2] (b) Some diseases are caused by infection of bacteria Write down the name of two other types of organisms that may cause a disease by infection MOSQUITO ant [2] © UCLES 2020 S/S6/01 [Turn over Yuri investigates how many sugar cubes dissolve in different temperatures of water In his first experiment Yuri: • • • • pours 100 cm3 of water into a glass beaker measures the temperature of the water keeps adding sugar cubes to the water until no more sugar dissolves records the number of sugar cubes that dissolve He repeats the experiment four more times Each time he uses water at a different temperature (a) Write down a prediction for this investigation Use your knowledge and understanding of particles to explain your prediction prediction explanation When the temperature is higher, the sugar dissolves faster and more When the temperature is higher, the sugar is easy to dissolve [2] (b) Name a piece of equipment used to accurately measure 100 cm3 of water [1] mesuring jar (c) Name a piece of equipment used to measure the temperature of water [1] thermometer (d) Explain why Yuri uses 100 cm3 of water in each experiment To have fair tests [1] (e) Write down the dependent variable in this investigation [1] temperature , sugar © UCLES 2020 S/S6/01 Scientists use models to describe electrical circuits Look at these two electrical circuits circuit A circuit B Both circuits have a cell and wires (a) Describe two other similarities between the two circuits They both have lights They both have switchs [2] (b) Describe two differences between the two circuits In circuit 1, the switch is close but in circuit 2, the switch is open Circuit is working , but circuit is not working [2] © UCLES 2020 S/S6/01 [Turn over 10 Mia finds some data about the eight planets of the Solar System Look at the table of data mean surface temperature of the planet in °C planet radius of the planet in km distance of the planet from the Sun in millions of km A 2440 58 280 B 3389 228 −55 C 6052 108 460 D 6371 150 14 E 24622 4495 −218 F 25362 2871 −224 G 58232 1434 −178 H 69911 779 −145 (a) Which letter shows the planet with the coldest mean surface temperature? [1] F (b) What is the name of the planet that is the furthest away from the Sun? [1] Neptune (c) Which letter shows data for Mercury? [1] A (d) Mia thinks that as the radius of a planet gets bigger, the planet is further away from the Sun Is she correct? No Use data from the table to explain your answer Because H is the biggest radius but it not the furthest plant [1] © UCLES 2020 S/S6/01 11 Look at the table of data It shows the mass and weight of the same object in different parts of the solar system part of the solar system weight of object mass of object in in Earth 10.2 100 Mercury 10.2 38 Pluto 10.2 the Moon 10.2 17 an asteroid 10.2 (a) Complete the table by writing the mass of the object on an asteroid [1] (b) The unit for mass is missing from the table What is the unit for mass? [1] kilograms (c) The unit for weight is missing from the table What is the unit for weight? [1] newton (d) Describe the difference between mass and weight mass is your amount, can know by stepping on the scale Weight is the gravity that push you down, can know by using newtonmeter [1] (e) Explain why the weight of the object is smaller on the Moon than on Earth Because the moon is smaller, smaller mean need less gravity [1] © UCLES 2020 S/S6/01 12 BLANK PAGE Copyright © UCLES, 2020 Cambridge Assessment International Education is part of the Cambridge Assessment Group Cambridge Assessment is the brand name of the University of Cambridge Local Examinations Syndicate (UCLES), which itself is a department of the University of Cambridge Permission to reproduce items where third-party owned material protected by copyright is included has been sought and cleared where possible Every reasonable effort has been made by the publisher (UCLES) to trace copyright holders, but if any items requiring clearance have unwittingly been included, the publisher will be pleased to make amends at the earliest possible opportunity © UCLES 2020 S/S6/01
