About the Worksheet for Class 7 Science

Science in Class 7 introduces students to a wide range of fascinating topics in physics, chemistry, and biology. To help students understand and apply these concepts effectively, worksheets play a crucial role. A worksheet for Class 7 Science is designed to reinforce classroom learning through practical questions, diagrams, and problem-solving exercises.

These worksheets cover all major chapters in the Class 7 Science curriculum, including Nutrition in Plants and Animals, Heat, Acids, Bases and Salts, Physical and Chemical Changes, Respiration in Organisms, and more. Each worksheet includes a mix of objective-type questions, like multiple choice and fill-in-the-blanks, as well as subjective questions such as short and long answers. One of the major advantages of Science worksheets is that they encourage active learning. For example, a worksheet on "Heat" may ask students to classify conductors and insulators, draw diagrams of a thermometer, or explain the concept of conduction with real-life examples. This makes learning more interactive and easier to grasp. Similarly, in biology-related topics like Respiration in Organisms or Transportation in Animals and Plants, students may be required to label diagrams of the respiratory system or explain the journey of water through a plant. These activities not only improve conceptual understanding but also help students retain information for a longer time.

In chemistry topics like Acids, Bases, and Salts, worksheets can include simple experiments or observations, such as using litmus paper to identify substances. These practical applications enhance the student’s interest in the subject and promote critical thinking. Another key feature of Science worksheets is revision-based exercises. These help students recap entire chapters through mind maps, summary tables, and short quizzes. They are especially useful before exams and class tests for quick and effective revision. Science worksheets can be used at school during classroom activities or at home as additional practice. They are ideal for self-assessment and help students identify their weak areas for improvement. In conclusion, worksheets for Class 7 Science are an essential resource that supports academic success. With well-structured questions and practical tasks, they help build a strong scientific foundation and nurture curiosity in young minds. Regular use of these worksheets leads to better understanding, higher retention, and improved performance in exams.

Find the questions from the Worksheet for class 7 Science

Questions based on Chapter 1: Nutrition in plants

1. Which of the following requires nitrogen for its synthesis?

(i) Carbohydrates

(ii) Proteins            

(iii) Fats

(iv) Vitamins

Explanation: Proteins are nitrogenous substances that require nitrogen for their synthesis.

 

2. Which of the following is a parasitic plant?

(i) Cuscuta  

(ii) Algae

(iii) Pitcher plant

(iv) Lichen

Explanation: Cuscuta does not have chlorophyll. It climbs a host plant and takes up its valuable nutrients. Thus it acts as a parasite feeding on a host plant.

 

3. Which of the following does not help in providing nitrogen to the soil?

(i) Peas

(ii) gram

(iii) beans

(iv) wheat              

Explanation: Nitrogen-fixing bacterium Rhizobium lives in the roots of the legumes like pulses, beans, peas etc. Wheat is not a legume.

 

Questions based on Chapter- 2 NUTRITION IN ANIMALS

 

1. In Amoeba, food particles are ingested in-

(a)    Nucleus.

(b)    Food vacuole.

(c)    Pseudopodium.

(d)    Cell membrane.

Ans:  (b)

Explanation:  Amoeba is a unicellular micro-organism that engulfs the food particles with the help of finger-like projections called pseudopodia. These engulfed particles are then ingested in the food vacuole where they are digested and absorbed. The undigested food is expelled out by the vacuole.

 

2. Why do human beings can’t eat grass?

(a)    They eat fruits and vegetables.

(b)    They are omnivorous.

(c)    They can’t digest cellulose.

(d)    Grass contains certain poisonous substances.

Ans:  Human beings lack cellulose-digesting enzymes, which are required for breaking the complex cellulose molecules. Since grass is rich in cellulose, hence, human beings are unable to digest cellulose.

 

Questions based on Chapter- 3 FIBRE TO FABRIC

 

1. Sorter’s disease is associated with-

(a)    Cotton industry.

(b)    Wool industry.

(c)    Silk industry.

(d)    None of the above.

Ans:  (b)

Explanation:  Sorter’s disease is associated with the wool industry in which the workers of the industry get infected by a bacterium, anthrax. It is a fatal blood disease.

 

2. Types of silk are-

(a)    Angora and mooga.

(b)    Tassar and kosa.

(c)    Angora and tassar.

(d)    Kosa and angora.

Explanation:  Tassar, manga and kosa are the types of silk while angora is a type of wool.

Questions based on Chapter- 4 HEAT

1. Can we measure the temperature of 45C from a clinical thermometer?

(a)    No.

(b)    Yes.

(c)    Sometimes.

(d)    From some clinical thermometers.

Ans:  (a)

Explanation:  We cannot measure the temperature of 45C from a clinical thermometer because a clinical thermometer has readings from 35C to 42C only.

 

2. What will happen to a clinical thermometer if we keep it in the Sun or near a flame?

(a)    It will measure the temperature.

(b)    It will break.

(c)    It will melt.

(d)    Nothing will happen.

Ans:  (b)

Explanation:  Since a clinical thermometer cannot measure high temperatures, hence, on keeping it in the Sun or near a flame, will break. It will not melt as the temperature of sunlight or around a flame is not so high, that it can melt the glass. 

3. Heat of the Sun reaches us by-

(a)    Reflection.

(b)    Condensation.

(c)    Radiation.

(d)    Sunlight.

Ans:  (c)

Explanation:  The heat of the Sun reaches us by a process called radiation. It is the process in which the transfer of heat does not require a medium to travel. Since there is no air in most of the space between the earth and the Sun, hence, heat from the Sun can easily pass through the vacuum to reach the earth’s surface.
