Q.1	Create an experiment using two plant pots, one covered with plastic wrap and the other left uncovered. Which observation would support the idea that greenhouse gases contribute to warming?
	a) The covered pot shows lower soil moisture compared to the uncovered one.		b) Both pots exhibit similar temperature increases.
	c) The covered pot shows a greater temperature increase than the uncovered one.		d) Both pots show a decrease in temperature.

Q.2	Analyse the graph below representing the water consumption patterns of a city over five years. Identify the trend in water consumption and propose a hypothesis explaining the observed pattern.
	a) Increasing trend; population growth leading to higher demand		b) Fluctuating trend; changes in climate affecting water availability
	c) Decreasing trend; successful implementation of water conservation measures		d) Stable trend; consistent water usage habits in the community

Q.3	Which practice aligns with the goal of "recycling" household waste?
	a) Throwing away mixed materials in one bin.		b) Composting organic waste separately.
	c) Discarding electronics with regular trash.		d) Mixing paper and plastic in the recycling bin.

Q.4	Sarah wanted to contribute to recycling efforts in her community. She collected various items like plastic bottles, glass jars, and old newspapers. How should Sarah effectively segregate these items for recycling?
	a) Recycle all the magazines without thinking.		b) Throw away the magazines because they're old.
	c) Reuse some magazines for crafts and recycle the rest.		d) Keep all the magazines because they're pretty.

Q.5	Alex is reviewing a research paper on atmospheric gases. Which gases in the atmosphere contribute significantly to the greenhouse effect, aiding in climate regulation?
	a) Oxygen and nitrogen		b) Nitrogen and helium
	c) Carbon dioxide and methane		d) Hydrogen and argon

Q.6	During a study of a deciduous forest, students encountered an interesting phenomenon related to tree species. They realised that certain trees played a vital role in supporting biodiversity. What specific characteristic of deciduous trees contributes to their importance in maintaining biodiversity, and how does it influence the forest ecosystem?
