Class 7 Science (Curiosity): Concept Navigators & Chapter Diagnostic Tests Select any unit below to use live science simulators and practice high-yield diagnostic questions from the new NCERT Curiosity curriculum with verified explanations. Interactive Concept Tool: Natural Acid-Base Indicator & Reaction Sorter Q1.What is the characteristic color shift observed when turmeric paper indicator is brought into contact with a basic solution (e.g., soap or lime water)? Answer: (b) It turns reddish-brown. Turmeric contains the natural pigment curcumin, which stays yellow in neutral and acidic media but turns distinctly reddish-brown in alkaline/basic solutions.
Q2.Which property uniquely distinguishes metals from non-metals, allowing metals to be drawn into thin electrical wires? Answer: (c) Ductility. Ductility is the physical property that allows metallic materials (like copper and aluminum) to be drawn into long, slender wires without fracturing.
Q3.Rusting of iron is classified as which type of change? Answer: (a). Rusting requires iron, oxygen, and moisture: $4\text{Fe} + 3\text{O}_2 + x\text{H}_2\text{O} \rightarrow 2\text{Fe}_2\text{O}_3 \cdot x\text{H}_2\text{O}$. A brand-new substance is formed with distinct properties, making it an irreversible chemical change.
Interactive Concept Tool: Plant vs. Animal Life Processes Navigator Q1.What green cellular organelle traps solar energy for synthesizing glucose in autotrophic plant cells? Answer: (b) Chloroplast. Chloroplasts contain chlorophyll, which captures radiant photons from sunlight to convert carbon dioxide and water into chemical energy (glucose).
Q2.In the human digestive tract, the primary site for the complete digestion and absorption of nutrients into the bloodstream is: Answer: (a) Small Intestine. The small intestine receives bile juice from the liver and pancreatic juice, completing carbohydrate, protein, and fat breakdown, with villi absorbing nutrients.
Q3.Which master endocrine gland located at the base of the brain initiates puberty by releasing hormones that trigger reproductive maturity? Answer: (c) Pituitary gland. The pituitary acts as the master regulator, secreting gonadotropins that stimulate the testes to produce testosterone and ovaries to produce estrogen.
Interactive Concept Tool: Speed & Pendulum Time Period Calculator Q1.By which mode of heat transfer does thermal energy from the Sun reach the Earth across the empty vacuum of space? Answer: (c) Radiation. Conduction and convection both require a material medium. Radiation travels through vacuum via electromagnetic waves at the speed of light.
Q2.What is the time taken by a simple pendulum to complete one full to-and-fro oscillation called? Answer: (b) Time Period (T). The duration of one complete cycle from extreme position to the other and back to the start is defined as its time period.
Q3.In an electrical circuit diagram, how is an electric cell represented symbolically? Answer: (a). Standard circuit schematic: the longer vertical line denotes the positive ($+$) terminal and the shorter, thicker line denotes the negative ($-$) terminal.
Interactive Concept Tool: Lunar Phases & Eclipse Geometry Sorter Q1.What type of image is formed by a flat, polished plane mirror? Answer: (b). Plane mirrors form virtual images behind the mirror at a distance equal to the object distance in front, exhibiting lateral inversion (left appears right).
Q2.A solar eclipse occurs only when: Answer: (a). During a solar eclipse (on Amavasya / New Moon), the Moon lines up precisely between the Sun and Earth, blocking sunlight and casting an umbra and penumbra shadow on Earth's surface.
Q3.What is the primary cause of the cycle of seasons on Earth throughout the year? Answer: (c). The fixed $23.5^\circ$ axial tilt ensures that different hemispheres lean toward the Sun during opposite parts of its annual orbit, altering solar radiation angles and creating seasons.
