In Class 9, every Indian student is expected to be able to apply theoretical knowledge to real-world situations. As a result, there is no shortage of practical examinations and many of them revolve around science subjects. Students who have a firm grasp of the fundamentals should have little trouble but reference books like Science Practical Book For Class 9 still prove handy. If you want to know whether the book deserves your time and money, it’s suggested that you check out my article.
A Summary Of The Book
Procedures : A single experiment might have several aims and most practical examinations usually provide procedures to guide you through. Science Practical Book For Class 9 follows the same format by stating the necessary apparatus and outlining procedures in a step-by-step fashion.
Observations : The main objective of an experiment is to test your knowledge in gathering data and how you reach the conclusion. Science Practical Book For Class 9 dedicates a section, usually as a table, where you get to note down your observations alongside the way you interpret them.
Questions : At the end of every experiment, the author prepared questions, both multiple choice and free form, for you to record/explain your interpretation.
Drawings : Science Practical Book For Class 9 includes relevant drawings that act as aids as you set up your experiment. The book sometimes leaves out components of the drawing and requires you to discover on your own. Noteworthily, in the second part of the book, you must provide drawings of your observation on occasions (for instance, the drawing of a cell you observed under the microscope).
Science Practical Book For Class 9: Breakdown
This practical book is divided into two main parts, Part and Part II, and each part contains fourteen practicals.
Science And Technology Part I
Part one is divided into two parts: the first term and the second term, and each features seven experiments. Instead of separating everything based on their subjects, Part I mixes physics and chemistry practicals together.
To Study Newton’s Laws of Motion.
To Study the dependence of the electric current (I) and the Potential difference (V) across a resistor and determine its resistance and plot a graph of V against I.
To verify the law of Chemical Combination.
To identify the basic radicals and acidic radicals in the given solution.
To determine the pH of the given samples using pH paper or Universal indicator.
To study the reactivity of acids and bases in terms of the neutralization principle.
Identify the acid, base, and salt from the given solutions using indicators.
To Study the formula of number of images from the number of images formed by changing the angle between two mirrors.
To determine the focal length of a concave mirror by obtaining the images of an object at different distances.
To verify the law of reflection of sound.
To determine that the activated charcoal is a decolorizing agent.
To prepare carbon dioxide in the laboratory and to study its physical and chemical properties.
To study the properties of baking soda and washing soda.
To find out the pH value of substances in everyday life with the help of universal indicators.
Science And Technology Part II
Unlike earlier subjects, Biology comprises a lot of experiments so Part II only concentrates Biology practicals. Similar to Part I, Part II offers you a total of fourteen experiments.
Classify the various plants (Spirogyra, Agaricus, Funaria, Fern (Nephrolepis), Cycas, Catharanthus) present in surrounding and sketching labeled diagrams.
Observation of various parts of the plants – hibiscus, and tuberose and explaining the difference according to classification criteria.
Sketching/ drawing/ constructing the food chains depending upon various components (producers, consumers) present in surroundings.
Making a list (study) of various organisms present in and around the water body near your school and explaining the food chain and food web according to their mode of nutrition.
Making yogurt from milk in the laboratory and studying the bacteria in it under the compound microscope.
Study of bacteria present in root nodules of leguminous plants.
Recording air temperature, air pressure, and humidity with the help of various instruments for a period of a week and writing a report about it.
Configure the garbage from the surroundings and make compost by using degradable garbage.
To study stomata by making a temporary slide of leaf peel.
To verify that the plants grow in the direction of sunlight.
To study the characteristics of ripe hybrid and local varieties of banana available in the market.
To identify striated muscle fiber and nerve cells in animal tissues from the prepared slides and draw their well-labeled diagrams.
Identify the parenchyma and sclerenchyma tissues in plants from the permanent slides and draw neat and labeled diagrams.
To study the section of stem found in surroundings.
