In this final chapter in our All About\u00a0Plants<\/a><\/strong> series, we will be discussing the following question:<\/p>\n

\n

Fruits dispersed by water or wind need to be light<\/span> in order to float on water or be carried by the wind respectively. Do you agree?<\/p>\n<\/blockquote>\n

When I posed this question to my students, most of them agreed with me.<\/p>\n

     <\/p>\n

    Here’re Their Explanations<\/span><\/h2>\n

    #1: Fruits\/seeds dispersed by water need to be light in order to float on water as heavier objects would sink<\/span>.<\/p>\n

    For example, when we compare a block of metal and a block of styrofoam of the same size, the block of metal will sink in water as it is heavier than the block of styrofoam.<\/p>\n

    #2: Fruits\/seeds dispersed by wind need to be light so that the wind can carry the seeds easily. This helps the seed to be dispersed further away from the parent plant.<\/p>\n

    Take a moment to ponder over their explanations. Do you agree?<\/span><\/p>\n

     <\/p>\n

    Let\u2019s Analyse Them Together!<\/span><\/h2>\n

     <\/p>\n

    Statement One<\/span><\/p>\n

    \n

    Fruits dispersed by water need to be light in order to float.<\/p>\n<\/blockquote>\n

    This statement is incorrect<\/span>.<\/span><\/p>\n

    The buoyancy of a fruit (i.e. whether it floats or not) is dependent on its density* (not in the PSLE Science syllabus).<\/p>\n

    To give your child an idea of what ‘Density’ is: Density is a measure of the mass of a substance<\/span> per unit volume<\/span>.<\/p>\n

    Look at how large and heavy ships can float on water. They do not float because they are light!<\/p>\n

    Your child should also take note that large objects may not necessarily sink in water. If you compare a large styrofoam block and a small metal block, the metal block would sink while the styrofoam block would float. The size of the object alone cannot determine if an object sinks or floats.<\/p>\n

    Hence, fruits do not need to be light in order to float on water.<\/span><\/p>\n

     <\/p>\n

    Statement Two<\/span><\/p>\n

    \n

    Seeds need to be light so that wind can carry the seeds easily.<\/p>\n<\/blockquote>\n

    This statement is correct<\/span>.<\/p>\n

    The amount of gravitational force acting on the seed (weight) depends on its mass.<\/p>\n

    The smaller the mass of an object, the lesser the gravitational force acting on the seed. This would allow the upward force of the wind acting on the seed to overcome the gravitational force acting on the seed more easily, allowing the seed to float more easily. This would enable the seed to float in the air for a longer period of time and be dispersed further away from the parent plant.<\/p>\n

    Hence, fruits need to be light in order to float in the air.<\/span><\/p>\n

     <\/p>\n

    In Conclusion<\/span><\/h2>\n

    The questions that I have discussed above cannot fully cover the questions<\/a> that have been tested in the PSLE Science syllabus.<\/p>\n

    However, I hope these articles have provided you a much better understanding of some of the key concepts in ‘Plant Cycle<\/a>‘ and how your child can apply them to the questions in his\/her examinations! \ud83d\ude42<\/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
