Environmental Studies
Environmental Studies carries 30 questions and is an integrated subject for Classes I–V, combining science, social studies and environmental education. It tests content about family, plants, animals, food, water, shelter, travel, communication, body, safety, maps and resources, plus EVS pedagogy.
Core content
- Living things need air, water, food and suitable temperature; plants make food using sunlight, water and carbon dioxide.
- Classification: insects have three body parts and six legs; snakes are reptiles with scales, not insects.
- Water changes state: evaporation, condensation, freezing; the water cycle links them.
- Maps use symbols, directions and scale; a sketch is not to scale.
- Resources are renewable or non-renewable; conservation includes reduce, reuse, recycle.
Pedagogy principles
EVS begins with the child’s immediate environment. Observation, questioning, classification, simple experiments, field visits and projects are central. A fair test changes one variable and keeps others constant. Assessment should credit explanation and evidence, not only recalled facts.
Worked example
A teacher asks, “Do plants need light?” Two similar potted plants are kept on a windowsill and in a dark cupboard. Both get the same amount of water and the same soil. After a week, the cupboard plant’s leaves are yellow and weak. Reason: light is the variable changed; water, soil and plant type are controlled. The conclusion is that light is needed for healthy growth - though the experiment does not by itself prove photosynthesis. A child who says “the dark plant died because it missed the sun” is giving a causal explanation; a child who says “it was sad” is animistic thinking and needs evidence-based probing.
Traps
Do not accept “it grew because we watered it” when light also changed - that confuses variables. Do not teach EVS as isolated facts; link to local water, waste and health. Do not treat a map as a picture. Do not ignore safety in experiments with heat or sharp tools.
