Q1 Cardinal Directions
How can you find the four cardinal directions (North, South, East, West) using the morning sun?
[3 Marks]
✅ Step-by-Step Solution & Working
Stand outside in an open area in the early morning and stretch your arms out wide:
1. Face directly toward the rising morning sun: That direction is East.
2. Your back points directly toward West (where the sun sets).
3. Your left hand points straight toward North.

Q2 Map Symbols & Key/Legend
Why do maps use small pictorial symbols instead of drawing full realistic pictures of buildings and roads?
[3 Marks]
✅ Step-by-Step Solution & Working
Real buildings, parks, and hospitals are too huge to draw on a portable sheet of paper. Standardized symbols (like a green circle for a tree, a red plus sign for a hospital, and a dashed line for railway tracks) take up very little space, keep the map neat and uncluttered, and can be understood universally by travelers regardless of their language.

Q11 Water Cycle & Weather • Rain and Clouds
Where does rainwater come from, and why do plants and trees look fresher and greener after a rain shower?
[3 Marks]
✅ Step-by-Step Solution & Working
Rain and Plant Health:
• Rain comes from water evaporating from rivers, ponds, and seas, forming clouds in the sky that cool and condense into rain droplets.
• Rain washes off thick dust accumulated on leaves, unblocks stomata for breathing, and deeply soaks the roots with fresh mineral-rich moisture.

Practical Navigation Skills: Creating a School Fire Evacuation Map

During a school safety audit, the principal asks the Class 3 students to help map out an emergency evacuation route from their second-floor classroom to the open playground.

Analytical Task: Apply your map-making skills to explain how students should design this safety evacuation route map.
Evaluation & Model Answer:
Students should design a clear, user-friendly emergency map: (1) Orient with Cardinal Directions: Place a Compass Rose (N, S, E, W) in the top-right corner. (2) Prominent Landmark Symbols: Mark classroom doors, emergency staircases, fire extinguisher locations (using a red cylinder icon), and first-aid kits (red cross). (3) Bold Green Directional Arrows: Draw thick green arrows showing the exact evacuation path down the stairs avoiding elevators. (4) Safe Assembly Point: Clearly highlight the open football field as the final safe gathering zone.
Rubric: Compass rose orientation, clear legend symbols (fire exits/extinguishers), sequential directional arrows, safe assembly zone (4 Marks).
