Here’s question on Mass that was posted by a parent\u00a0on our Parent Support Group<\/a><\/span>.<\/span><\/span>\u00a0<\/span><\/strong><\/p>\n

Your child needs to know how to link the concepts from Mass and Energy<\/a><\/strong>\u00a0to tackle these questions accurately.<\/p>\n

    In this article, I will break\u00a0down the thought process to show you how we analyse this question & you can share this with your child if you find this helpful.<\/p>\n

    Question<\/span><\/h2>\n

    \"\"<\/p>\n

     <\/p>\n

    Thought Process<\/span><\/h2>\n

    The four balls are of the same size and volume but are made of different materials.<\/p>\n

    As copper and iron are denser than styrofoam and paper, the mass of the copper (W) and iron (Z) ball will be larger than the styrofoam (X) and paper (Y) ball.<\/p>\n

    Hence, this suggests that Statement B<\/span>, “Ball W has a greater mass than Ball X<\/span>“<\/span> is correct<\/span>.<\/p>\n

    The four balls in the diagram share the same cross-sectional area, therefore the air resistance acting on the balls are the same.<\/p>\n

    As such, the four balls will reach the sand at the same time.<\/p>\n

    Therefore, this shows that S<\/strong>tatement C<\/span>, “All the balls will reach the sand at the same time”<\/span> is correct<\/span>.<\/p>\n

    Based on this line of thought, we can also safely eliminate <\/span>Statement A<\/span>, “Ball Y will reach the sand first<\/em>” and Statement D<\/span>, “Ball W and Z will reach the sand before Ball X and Y<\/em>“.<\/p>\n

     <\/p>\n

    Note:<\/span><\/h3>\n

    The concept of “Density” is not tested at the PSLE level.<\/p>\n

    However, students are required to recognise that different materials have different densities.<\/p>\n

    Therefore, different objects with the same volume, may weigh more than others because of different densities.<\/p>\n

     <\/p>\n

    Final Answer<\/span><\/h2>\n

    The final answer is Option (2) – Statements B and C\u00a0are correct<\/span>!<\/span><\/p>\n

    I hope that this article has shown you the right thought process needed to tackle questions that test concepts from both Mass and Energy<\/strong><\/a>\u00a0and how to arrive at the correct answer!<\/p>\n

    Today\u2019s Question:<\/span><\/h2>\r\n
    How Should The Bulb Be Connected To The Circuit For It To Light Up?<\/strong><\/span><\/blockquote>\r\n

    The following question is commonly encountered by students during tests.<\/p>\r\n

    \"\"<\/a>Question Credit: Anglo Chinese School (Junior)\/ 2015 Primary 5 SA1\/ Question 18<\/em><\/p>\r\nWe can see that the key difference between the four options is the connection of the bulb(s) in the circuit.\r\n

    Requirements Needed for a Bulb to Light Up<\/span><\/strong><\/h3>\r\n\u00a0\r\n\r\n\"\"<\/a>\r\n\r\n\u00a0\r\n\r\nOne wire is connected to the metal casing & one wire is connected to the metal tip<\/u><\/strong>\r\n\r\n\u00a0\r\n

    \"\"<\/a>Example of a closed circuit<\/em><\/p>\r\nWhen the wires in the circuit are connected to the metal casing and metal tip of the bulb, there is a closed (or complete) circuit with the bulb. Electricity will be able to flow through the filament, causing the bulb to light up.\r\n

    What Happens When Both Wires Are Connected To The Metal Tip\/Metal Casing?<\/strong><\/span><\/h2>\r\nScenario #1: Both wires are connected to the metal tip<\/strong><\/span>\r\n\r\n\"\"<\/a>\r\n

    Example of a circuit when the wires are connected only to the metal tip<\/em><\/p>\r\nWhen both wires are connected to the metal tip of the bulb, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n\r\nScenario #2: Both wires are connected to the metal casing<\/strong><\/span>\r\n\r\n\u00a0\r\n

    \"\"<\/a>Example of a circuit when the wires are connected only to the metal casing<\/em><\/p>\r\nWhen both wires are connected to the metal casing of the bulb, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n\r\nNow, let us now take a look at the question again.\r\n

    Analysis Of The Options<\/strong><\/span><\/h2>\r\n\"\"<\/a>\r\n\r\nWhen analysing the circuits, students need to take note of one key point:\r\n

    How is the bulb connected to the circuit?<\/strong><\/span><\/h3>\r\nIn the following analysis, I have traced the pathway that electricity flows through (in red) as well so that it is easier to understand why the bulb lights up.\r\n

    Circuit A<\/strong><\/span><\/p>\r\n\"\"<\/a>\r\n\r\nBoth the metal casing and tip of the bulb are connected to the circuit, forming a closed circuit. Thus, electricity is able to flow through the wires in the circuit to the filament, allowing the bulb to light up.\r\n

    Circuit B<\/strong><\/span><\/p>\r\n\"\"<\/a>\r\n\r\nOnly the tip is connected to the circuit. Thus, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n

    Circuit C<\/strong><\/span><\/p>\r\n

    \"\"<\/a><\/p>\r\nOnly the casing is connected to the circuit. Thus, electricity is unable to flow through the filament, preventing the bulb from lighting up.\r\n

    Circuit D<\/strong><\/span><\/p>\r\n

    \"\"<\/a><\/p>\r\nBoth the metal casing and tip of the two bulbs are connected to the circuit, forming a closed circuit. Thus, electricity is able to flow through the wires in the circuit to the filaments, allowing the bulbs to light up.\r\n\r\nAs the bulbs in circuits A and D will light up, the correct answer is option 4.\r\n

    What We Have Learnt Today<\/strong><\/span><\/h2>\r\nWhen students wish to find out if the bulb will light up, they should check the following:\r\n

    Are both the metal casing and the tip of the bulb connected to the circuit?<\/span><\/strong><\/h3>\r\nIf the answer to the question is \u2018yes\u2019, the bulb will light up. :)\r\n\r\nIn the next blog post, I will be sharing about the advantages and disadvantages of arranging bulbs in series and in parallel.\r\n\r\nStay tuned! :)\r\n\r\n
