## MAN Mathematics for Junior Secondary Schools ### Their observations and the results of their experiments * If the experiments support the hypothesis, they carry out further investigations. * They discuss the hypothesis and results with other scientists in the field so that the hypothesis can be further observed while * The hypothesis has been tested and found to be correct with the limits of available evidence. It becomes a theory - A scientific law of principles. * Established only after the theory has been extensively tested and proven true without any exceptions. * If the experiments give negative results, then the scientists go back to their hypothesis and either modify it or put forward a new hypothesis * This way of studying a problem is known as the scientific method and its the very foundation of all scientific discoveries. ### LABORATORY APPARATUS Lab laboratory apparatus refers to the various tools or equipment used by scientists working in the laboratory. Some common laboratory apparatuses include: * Test tubes, beakers, conical flask, flat bottomed flask, round bottomed flask, funnel (plastic or glass), thistle funnel, brush flask, funnel (woulff’s bottle tripod stand, retort stand, spatula, Bunsen burner, separating funnel, wire gauze, lamp, beehive design aboreaux condenser,.... ### THE CLAMP: is used as experiments * It is used in keeping and liquids in an atmosphere that's free of dust. ### MEASURING CYLINDER: * To measure the volume of liquids. ### KIPPS APPARATUS: * For intermittent
