Additional Concepts
Papier-mâché is a material made from paper pulp mixed with glue or clay. It is used to make decorative items. Leftover food can be added to compost pits instead of being thrown away. Choosing eco-friendly options like banana leaf plates instead of plastic helps reduce pollution.
- ScienceClass 6CBSE
Useful and Harmful Garbage
Not all garbage is harmful. Some waste materials can be reused or recycled, while biodegradable waste can be converted into compost. Proper segregation helps in utilizing waste effectively.
- ScienceClass 6CBSE
Landfills and Waste Disposal
A landfill is a low-lying area where non-useful waste is dumped. However, landfills can cause pollution if not managed properly. Therefore, reducing waste and recycling are better options than dumping garbage.

Compost vs Chemical Fertilizers
Using compost is better than chemical fertilizers for several reasons: Compost provides natural nutrients to plants It improves soil structure and fertility It is eco-friendly and inexpensive Chemical fertilizers can cause soil and water pollution Thus, composting is a sustainable and environmentally friendly practice.

Recycling and Reuse
Recycling helps in converting waste materials into new useful products. Items like newspapers, notebooks, magazines, and envelopes can be recycled. However, plastic-coated or shiny paper cannot be recycled easily. Recycled paper is slightly different from new paper. Over time, its quality decreases, and it may be used for making carry bags or packaging materials.
- ScienceClass 6CBSE
Packaging and Its Impact
Packaging contributes significantly to the increase in garbage. Many products are sold in small packets, which use a lot of plastic and other materials. This leads to more waste generation. We can reduce packaging waste by: Buying products in bulk Using cloth or reusable bags Avoiding plastic packaging

Methods to Reduce Garbage Problems
The problem of garbage disposal can be reduced by following simple practices: Segregation of waste into biodegradable and non-biodegradable using two dustbins Composting organic waste at home Recycling materials like paper, glass, and metals Avoiding excessive use of plastic Municipalities usually provide two types of du

Responsibility of Garbage Disposal
Garbage disposal is not only the responsibility of the government but also of every individual. If people do not manage their waste properly, it can lead to unhygienic conditions and spread diseases. Since we generate garbage every day, it is our duty to handle it responsibly by reducing, reusing, and recycling waste.

Other Organisms in Compost Pit
Apart from red worms, microorganisms like bacteria and fungi are also present in compost pits. These organisms help in breaking down organic matter into simpler substances, making the compost more useful for plants.
- ScienceClass 6CBSE
Role of Red Worms and Vermicomposting
Red worms play an important role in converting biodegradable waste into compost. They feed on organic waste like fruits, vegetables, and food remains. Inside their body, the food is ground with the help of a special organ called a gizzard, and then converted into nutrient-rich compost. This process of making compost using red worms is called vermicomposting. It is an eco-friendly method that helps in recycling waste and improving soil fertility. However, red w

Biodegradable and Non-Biodegradable Waste
Biodegradable waste includes materials that can be decomposed naturally by microorganisms. Examples include vegetable peels, fruits, tea leaves, and leftover food. These wastes can be converted into useful compost. Non-biodegradable waste includes materials that do not decompose easily. Items like plastic bags, synthetic cloth, glass, aluminum wrappers, and broken toys fall under this category. These materials remain in the environment for a long time and caus

Name of Chapter–Garbage In Garbage Out
Garbage and Waste Management – Explanation Garbage is an unavoidable part of our daily life. Every day, we generate waste from our homes, schools, markets, and industries. Proper disposal and management of garbage are essential to keep our surroundings clean and healthy. Waste can be divided into two main types—biodegradable and non-biodegradable.

Suggest an activity to prepare a magnetic compass by using an iron needle and a bar magnet.
To prepare a magnetic compass, place the given iron needle on a wooden table now magnetize by rubbing a bar magnet over it repeatedly in a particular direction without lifting it. After that it may be set in a way so that it can rotate freely when suspended. Hence, the iron needle can act as compass and give north-south direction.

Three identical iron bars are kept on a table. Two out of three bars are magnets. In one of the magnet the North-South poles are marked. How will you find out which of the other two bars is a magnet? Identify the poles of this magnet.
The magnet on which the North-South poles are marked can be used to find out the magnet out of two bars. Take the magnet with North-South poles are marked, keep it close to both the iron bars, hence both magnets gets attracted to it since both are magnets. To find out the poles of unknown magnet, we can use the repulsion test. North pole marked on the given magnet will repel the north pole of unknown magnet and vice-versa.

You are provided with two identical metal bars. One out of the two is a magnet. Suggest two ways to identify the magnet.
Solution: There can be following ways to identify the magnet out of the two identical metal bars: By attracting iron filings to the magnet we get to know which is a By using another magnet. If it is a magnet, like poles will repel each other while unlike poles will attract each other.

Match column I with column II (One option of A can match with more than one option of B. Column I Column II (a) Magnet attracts (i) rests along a particular direction (b) Magnet can be repelled by (ii) iron (c) Magnet if suspended freely (iii) another magnet (d) Poles of the magnet can be identified by (iv) iron filings
Solution: Here is the correct match: Column I Column II (a) Magnet attracts (ii) iron, (iii) another magnet, (iv) iron filings (b) Magnet can be repelled by (iii) another magnet (c

A toy car has a bar magnet laid hidden inside its body along its length. Using another magnet how will you find out which pole of the magnet is facing the front of the car?
Solution: we know that unlike poles attract each other while like poles repel each other. In case of toy car, if the front of the toy car gets attracted to the north pole of the given magnet then it is the south pole of the bar magnet hidden inside the car and vice-versa.

How will you test that ‘tea dust’ is not adulterated with iron powder?
We can use magnet to test that tea dust is not adulterated with iron powder. If it has iron powder it will stick to the magnet.

Paheli and her friends were decorating the class bulletin board. She dropped the box of stainless steel pins by mistake. She tried to collect the pins using a magnet. She could not succeed. What could be the reason for this?
Solution: The pins are made of stainless steel which is a non-magnetic material. Hence Paheli was unsuccessful in collecting the pins using a magnet.
