When I first entered the physics classroom I was\noverwhelmed with all the apparatus that was spread around the laboratory. I was very excited to use the apparatus, but because of the\npandemic we could not do any experiments ourselves. The teacher, however,\nperformed demonstrations of the experiments and we still learned\nfrom them.<\/p>\n\n\n\n

The first topic we learned about in year 9 was \u2018Density\u2019. In this topic we calculated how dense certain materials were\nby using the formula \u2018density = mass\/volume\u2019. In this topic the teacher\nconducted multiple experiments. One of these experiments was very interesting.\nIt was called the density column. In this experiment we mixed a lot of different liquids\nand tested if they sank or floated on each other. Some of them sank at the\nbottom, others floated at the very top. This was one of the experiments we\ncould have done at home, and that\u2019s what we did! The teacher invited us to try\nand make our own column. The density column is a very simple and fascinating experiment and I encourage\nyou to try it yourself.<\/p>\n\n\n\n

The density column I made consisted of:
1st layer: Syrup
2nd layer: Dish Soap
3rd layer: Hand Sanitizer
4th layer: Vegetable Oil. <\/p>\n\n\n\n

The next topic we did was \u2018Forces\u2019. In this\ntopic we learned that there are multiple forces present in everyday activities,\nsome of which include: Tension force, Frictional Force, Gravitational Force and\nmuch more! Two very important scientists are mentioned constantly\nin this topic: Robert Hooke, and Isaac Newton.<\/p>\n\n\n\n

Robert Hooke discovered that springs have a\nlimit to where they can be stretched, and that before they reach this limit\nthey follow a certain law which when drawn on a graph is a straight line from zero.<\/p>\n\n\n\n

Isaac Newton is famous for his discovery of gravity. We studied his three laws.<\/p>\n\n\n\n

Forces is very a fun topic, since many\nexperiments are conducted and it is a straightforward topic.<\/p>\n\n\n\n

The subsequent topic was \u2018Pressure\u2019. In \u2018Pressure\u2019 we learn\nthat pressure is experienced\nin the three states of matter: solids, liquids and gases. We have different formulas for each and every state of matter. This\ntopic was very engaging since we had the opportunity to learn about hydraulic machines and\nhow they work! The experiments were really compelling and we also built our own\nmini hydraulic machine; all it took was two syringes, a pipe going from one\nsyringe to the other, and some water in them. <\/p>\n\n\n\n

The last topic we learned about was \u2018Moments\u2019. This subject was truly enjoyable since it applies to everything\nthat has a turning point, or a pivot, for example: doors, levers, wrenches and\nmuch more! In \u2018Moments\u2019 many experiments were conducted and they were always\ninteresting. \u2018Moments\u2019 included other topics such as \u2018Forces\u2019 and \u2018Centre of Gravity\u2019.<\/p>\n\n\n\n

At the end of a physics lesson, I always feel a\nsense of fulfilment which is owed to the newly acquired knowledge. My favourite\ntopic so far has been \u2018Density\u2019 since it comprised some of the most challenging\nlessons. Physics is a fascinating subject which makes me want to learn more everyday!<\/p>\n","protected":false},"excerpt":{"rendered":"
