1. why do people in their communities recycle paper, glass, aluminum and other materials?
2. how organisms in the environment use the suns energy?
3. what materials can usually be recycled, and why is it important to separate them correctly?
4. what is one way people can improve recycling in their homes or communities?
5. how does recycling help reduce the amount of waste in landfills and protect the environment?
6. why is water essential for life?
7. why cant you live without carbon?
8. why is nitrogen essential for life?
9. what are the three physical forms of water?
10. what is the difference between evaporation, condensation, precipitation and transpiration?
11. why do plants need water?
12. how can human activities, like urban development, affect the natural flow of the water cycle?

Explanation:

1. Recycling conserves resources, reduces waste and energy - use.
2. Organisms use solar - energy for photosynthesis (plants) and as an energy source through food - chains.
3. Common recyclables include paper, plastic, glass, metal. Separation is crucial for efficient recycling.
4. One way to improve recycling is by better education and awareness in communities.
5. Recycling reduces landfill waste as materials are reused instead of being dumped, and it conserves natural resources and energy, protecting the environment.
6. Water is essential for life as it is a solvent for biochemical reactions, helps with temperature regulation, and is involved in transport processes in organisms.
7. Carbon is a key element in organic molecules like carbohydrates, proteins, lipids, and nucleic acids, which are essential for life processes.
8. Nitrogen is essential for life as it is a component of amino acids (building blocks of proteins) and nucleic acids (DNA and RNA).
9. The three physical forms of water are solid (ice), liquid (water), and gas (water vapor).
10. Evaporation is the change of liquid water to water vapor; condensation is the change of water vapor to liquid; precipitation is the fall of water (in various forms like rain, snow) from clouds; transpiration is the release of water vapor from plants.
11. Plants need water for photosynthesis, nutrient uptake, and to maintain turgor pressure for structural support.
12. Urban development can change the natural water - flow by creating impervious surfaces (roads, buildings), which can lead to increased runoff, reduced infiltration, and altered water - cycle patterns.
