Q1In a Class 7 resource-walk, Asha's group maps water points and Devika's group records plastic and paper waste without touching it. Which teacher action best turns these observations into science learning?

A Ask each group to write a slogan and paste it near the classroom door
B Tell the class that plastic is bad and water is precious, then end the activity
C Have groups fill columns for resource seen, possible problem and conservation action, then compare evidence
D Make students copy a paragraph on pollution from memory
Explanation

The best teaching move uses the children's own observations to classify resources, identify problems and choose practical responses. Slogans, lectures and memory writing do not build the same evidence-based reasoning.

Q2Which resource-process-pressure-response chain is scientifically correct?

A Groundwater - recharge by rain - over-extraction - rainwater harvesting and careful use
B Soil - evaporation from leaves - traffic smoke - switching off lights
C Forest - melting of ice - groundwater pumping - using more fossil fuel
D Plastic - soil formation - plant cover loss - controlled grazing
Explanation

A good chain connects one resource to its process, pressure and response. Groundwater is recharged by rain, can fall when withdrawal is too fast, and can be conserved through rainwater harvesting and careful use; the other chains mix unrelated ideas.

Q3Assertion: A renewable resource can become scarce in a local area. Reason: Its use may be faster than its recharge or regrowth. Choose the correct option.

A Both the assertion and the reason are true, and the reason correctly explains the assertion.
B Both the assertion and the reason are true, but the reason does not explain the assertion.
C The assertion is true, but the reason is false.
D The assertion is false, but the reason is true.
Explanation

Renewable resources depend on a renewal process, so the rate comparison matters. Groundwater and forests can decline locally when withdrawal, cutting or damage is faster than recharge or regrowth; the other options miss this cause-effect link.

Q4Which statement is an incorrect environmental science idea often used as an MCQ trap?

A Conservation includes careful use, reuse, repair and community monitoring.
B A biodegradable item is always harmless wherever it is dumped.
C Greenhouse gases are a cause-side factor in global warming.
D Non-renewable fuels such as coal, petroleum and natural gas form over geological time.
Explanation

Biodegradable does not mean harmless in every situation. Organic waste dumped in excess or into water can foul the place and reduce oxygen, while the other statements correctly describe conservation, greenhouse gases and fossil fuels.

Q5Assertion: Groundwater can become scarce in a village even though rain can recharge it. Reason: A renewable resource may decline locally when use is faster than recharge.

A Both the assertion and the reason are true, and the reason correctly explains the assertion.
B Both the assertion and the reason are true, but the reason does not explain the assertion.
C The assertion is true, but the reason is false.
D The assertion is false, but the reason is true.
Explanation

Rain can recharge groundwater, but the stock still falls when pumping or use is faster than recharge. This is why renewable should not be confused with unlimited; the other options break the cause-and-effect link.

6Which statement correctly avoids the common trap about biodegradable waste?

ABiodegradable waste is always harmless, so it can be dumped in any water body.
BBiodegradable waste can break down, but excess dumping can still pollute water.
CBiodegradable waste never affects oxygen conditions in water.
DBiodegradable and non-biodegradable wastes need the same disposal method.

7Which option best defines a natural resource for middle-stage science?

AA naturally occurring material, organism or energy flow used by living beings for needs such as food, shelter or work
BAny object made in a factory that reduces human labour
COnly those substances that can be sold in a market for money
DOnly non-living materials such as rocks, metals and water

8Consider the following two statements about renewable resources. Statement I: A renewable resource can become scarce in a local area. Statement II: Scarcity can occur when use is faster than recharge or regrowth. Which option is correct?

ABoth statements are true, and Statement II correctly explains Statement I
BBoth statements are true, but Statement II does not explain Statement I
CStatement I is true, but Statement II is false
DStatement I is false, but Statement II is true

9Which two statements together show the best science meaning of conservation?

AUse nothing from nature; all resource use is harmful
BUse resources freely now; future supply is a separate issue
CUse resources carefully and maintain regeneration, quality and balance
DProtect only wildlife; water, air and soil need no management

ALooking Around
BScience and Technology
CCuriosity
DOur Environment

11Assertion: Devika should not call every biodegradable waste item harmless. Reason: Excess organic waste in water can reduce water quality. Choose the correct option.

ABoth assertion and reason are false
BAssertion is true, but reason is false
CAssertion is false, but reason is true
DBoth are true, and the reason explains the assertion

12Asha sees muddy water running off a bare patch after rain. Which teacher question best builds evidence-based reasoning?

AWho made the ground dirty?
BShould we memorise that all rain is harmful?
CHow does plant cover change the amount of soil carried by runoff?
DCan we ignore this because soil is found everywhere?

13For revising groundwater as a natural resource, which sequence correctly follows the resource-process-pressure-response chain?

ARainwater harvesting - groundwater - recharge - overuse
BGroundwater - recharge - overuse - rainwater harvesting
COveruse - rainwater harvesting - groundwater - recharge
DRecharge - overuse - rainwater harvesting - groundwater

14Which statement correctly uses the resource-process-pressure-response chain for classroom revision?

APlastic - photosynthesis - overgrazing - rainwater harvesting
BForest - regrowth - repeated cutting without regeneration - controlled use and planting
CCoal - evaporation - recharge - composting
DSoil - combustion - greenhouse gases - switch off lights

15Which statement best shows why a one-day dust-card reading near the school gate is not enough for a permanent conclusion?

ADust is never connected with air quality
BOnly expensive gas sensors can teach air pollution
COne reading is final if the teacher says it is final
DRepeated observations are needed because traffic, wind and activity vary
