📘 Class 7 General Science – Unit 1: The Wonderful World of Science (AP SCERT) – Answers & Solutions
Class 7 General Science Unit 1 "The Wonderful World of Science" is the opening chapter of the AP SCERT Class 7 Science textbook, introducing students to scientific thinking, curiosity, observation and experimentation. This unit connects everyday experiences — like sour fruits, haldi stains, torch batteries, melting ice, shadows and eclipses — to the different branches of science: physics, chemistry, biology and earth science. It sets the stage for the entire Class 7 Science syllabus (AP State Board / SCERT), encouraging young learners to ask questions, explore, and think like scientists. Below are complete, easy-to-understand answers for Activity 1.1 "Question the Answer" (Pages 30–40), perfect for students, parents and teachers looking for Class 7 Science Unit 1 solutions, AP SCERT General Science answers, and 7th class science activity answers.
📄 Page 40 – Activity 1.1: Question the Answer
Instructions recap: For each answer given below, students must imagine and write a fun, creative question that could lead to that answer. There are no wrong questions here — imagination is the goal! Here are sample creative answers a Class 7 student could write:
1) Question: What should I do if my tea tastes too strong and bitter?
Answer: Just add some milk.
2) Question: Why couldn't the kitten hold onto the piece of fish properly?
Answer: Because the cat's teeth were crooked.
3) Question: What did the space traveller say to calm his frightened friends when they got lost?
Answer: Don't panic, I have my towel.
4) Question: What number did the robot shout out when the teacher asked it to pick its lucky number?
Answer: 42.
📝 Note: These are sample creative questions. Since Activity 1.1 is an open-ended imagination exercise, students can write their own original questions too — any question that logically or humorously fits the answer is considered correct. There is no single "correct" answer for this activity.
✅ Key Points Covered in Unit 1 (Pages 30–39)
- Science is a process of asking questions, observing, and experimenting — not just a collection of facts.
- Different fields of science (physics, chemistry, biology, earth science) are interconnected.
- Properties of materials, metals and non-metals, electric circuits (battery, lamp, wires).
- Reversible and irreversible changes — e.g., ice melting, rocks breaking, fruit ripening, batteries running out.
- Heat flow — melting of ice, glaciers, evaporation and the water cycle.
- Life processes in plants and animals — eating, breathing, growth, circulation of nutrients.
- Measuring time — from sundials and shadows to modern clocks.
- Light and shadows — reflection, day and night, eclipses, Earth's rotation and revolution.
- Science helps us understand our responsibility towards the environment and a sustainable world.
