1 Foundation Tier 3 6 Test ame Class 1 Blood is pumped around the body by the heart. a Write the following in the order blood passes through them after leaving the heart. veins arteries capillaries First next last b Choose from the list of organs in the box to answer the question. brain bones heart intestines lungs stomach From which organ does blood gain: i digested food oxygen? c Fibre and starch are made from the same chemicals but provide different parts of a balanced diet. i What type of nutrient or food substance is starch? What is formed by the digestion of starch? d ot all the substances that we eat or drink are good for our bodies. ame one substance that we can drink which may be harmful. 2 a By the side of each pair of magnets write whether they attract or repel each other.

2 b Draw a pair of magnets where the force of repulsion between the magnets is greater than those shown above. athan was given three pieces of metal. Each was wrapped up in masking tape. He used a magnet to investigate each one. The first one was attracted to both the north and south poles of his magnet. The second one was attracted to the north pole but repelled by the south pole. The third one was not attracted or repelled by either pole of his magnet. c Which one was a piece of unmagnetised iron? d Draw the other part of the magnetic field around the bar magnet below. 3 The drawing shows the crust of the Earth around an ancient volcano. ancient volcano cone made of lava layer of basalt layers of sedimentary rock solidified magma Page 2 of 7 3 Pearson Education Limited 2002

3 a Where did the cone of lava come from? b What type of rock is basalt? Choose from: igneous metamorphic sedimentary c Mark on the diagram where each of the following might be found: i metamorphic rock write M granite write G i igneous rock containing the largest crystals write I. [3 marks] d Three layers of sedimentary rock are shown: upper, middle and lower. Which one is probably the oldest? 4 For a fuel to burn it has to be heated. a Complete the fire triangle to show what else is needed. Heat Fuel b To put out a fire one part of the fire triangle has to be removed. i Which part is removed when a hose pours water onto a fire? Which part is removed when carbon dioxide or foam is sprayed onto a fire? Page 3 of 7 4 Pearson Education Limited 2002

4 c What are the names of the compounds formed when each of the following burn in air? i carbon hydrogen i magnesium 5 eris was investigating the current in a circuit containing a number of switches, bulbs and ammeters. The results eris obtained are given in the table. A 1 umber of bulbs Current in switched on ammeter A 1 (A) A 3 A 2 a i Plot the results and draw the graph on the axes below Use the graph to predict the current in A 1 when four bulbs are switched on. A Page 4 of 7 5 Pearson Education Limited 2002

5 b Choose from the words in the box to complete the sentence. line parallel series opposition The ammeter A 2, the bulb and the switch are in with each other. c eris has all four switches closed and the bulbs are lit. On the circuit diagram: i Draw in an ammeter labelled A 4 that has the same reading as A 3. Draw in an ammeter labelled A 5 that has the same reading as A 2. 6 You are given an unlabelled test tube containing a colourless gas and you are asked to find out what gas is present. Describe the tests to show if each of the following gases is present. a oxygen b hydrogen c carbon dioxide 7 a Complete the ray diagram to show the ray of light from the torch bulb hitting the mirror and reflecting off it. mirror bulb Page 5 of 7 6 Pearson Education Limited 2002

6 b Draw an X on the diagram to show where your eye must be for you to see the image of the torch bulb. c When white light travels through a glass prism it is bent and broken up into colours. i Put the colours in the box in the correct order starting with the colour that is bent the most and ending with the one that is bent the least. blue green red yellow Complete the drawing below to show a ray of white light passing into and through the glass. Do not show it emerging from the glass. 8 In 1953, tanley Miller and Harold Urey reproduced what it was like in the Earth s atmosphere millions of years ago. For a week they sparked lightning through a mixture of methane, ammonia, hydrogen and water vapour contained in a sealed flask. They found that four different amino acids were formed. Amino acids are molecules that join together to make protein, which is a building block of living things. a Which substance in the mixture is an element? b What is the source of energy for the chemical changes that occurred in the Earth s atmosphere in the sealed flask? c i What part of our diet could have been made in the Earth s atmosphere millions of years ago?

7 Foundation Tier 3 6 Test (continued) tanley Miller and Harold Urey said that their experiment showed how life could have started on Earth millions of years ago. What group of substances is their evidence for this? In ancient times people believed that life could arise spontaneously, or from nothing living, such as maggots from dead animals and eels from the ooze of rivers. A famous experiment to show that life did not start out of nothing was done by Abbé Lazzaro pallanzani ( ). He showed that if he boiled broth and sealed it from air, while it was boiling, bacteria never grew in it; but as soon as air was let in clumps of bacterial growth began to appear. Louis Pasteur ( ) carefully repeated the experiments and confirmed that the cause of the clumps of bacterial growth was tiny bacteria getting in from the air. Until Pasteur repeated and confirmed pallanzani s experiments, the scientists of the time still thought that living bacteria spontaneously appeared from the chemicals in broth. d Originally it was argued that pallanzani s experiments were not reliable. What made them become reliable? e How could pallanzani s critics have used Miller and Urey s results to argue that pallanzani s conclusion was wrong? f Zacharias Jannsen invented the microscope in How could a powerful microscope have helped pallanzani to prove his conclusion?
