NCERT Solutions for Class 7 Science Curiosity Chapter 1: The Ever-Evolving World of Science by PW

Science begins with observing everyday situations, asking questions and finding logical explanations. However, some textbook questions may appear simple while requiring you to understand the situation carefully. The chapter includes examples related to food, animals, daily experiences and simple calculations to introduce scientific thinking.

The Class 7 Science Curiosity Chapter 1 Solutions provide answers and explanations for the textbook questions from The Ever-Evolving World of Science. They help explain the given situations through simple reasoning and show how everyday observations can be connected with scientific thinking and problem-solving.

Class 7 Science Chapter 1 NCERT Solutions

Chapter 1, The Ever-Evolving World of Science, introduces students to scientific curiosity and creative thinking. In Activity 1.1, “Question the Answer,” students are given four answers and asked to frame interesting questions or situations that could lead to them. The objective is not to memorise fixed answers but to learn how to ask meaningful questions and explore different possibilities.

The following are sample questions for the four answers given in the NCERT textbook. Other creative and logical questions are also acceptable.

Q1. Frame an interesting question for the answer: “Just add some milk.”

Sample questions: 

• The tea is very strong. How can I make it lighter in taste?

• My coffee tastes too bitter. What should I do?

• I don't like eating dry chocolates. How should I eat them?

Q2. Frame an interesting question for the answer: “Because the cat’s teeth were crooked.”

Sample questions: 

• How can cats easily tear the flesh of their prey?

• Why was the kitten unable to bite properly?

Q3. Frame an interesting question for the answer: “Don’t panic, I have my towel.”

Sample questions:

• I have my exam in a few minutes, and I'm completely wet due to rain. What should I do?

• I accidentally spilt water on myself before my presentation. What should I do? 

Q4. Frame an interesting question for the answer: “42.”

Sample question: There were 21 married couples in a building. If each couple has two people, how many people are there in total?

Number of couples = 21

People in each couple = 2

212=42
