Garbage in and Garbage out (Part - 3)

 Garbage in and Garbage out (Part - 3) 

Q.15. What do we mean by 4R’s method to deal with the non-biodegradable garbage?

Ans. We can expand the 4R's method as:

Recycle: collecting waste materials and processing them to make new products.

Reuse: reuse whatever can be for other purposes.

Reduce: minimize the use of the material which is difficult to get disposed off.

Refuse: strictly refuse/ban the use of such material which is difficult to get disposed off and is harmful to environment as well.



Q.16. Plastic is a boon or a curse. Justify.

Ans. Plastic as a boon: Plastic has some special features like it is cheap in cost, light in weight and durable in comparison to other materials. So, the list of materials made from plastics is generally very long like Toys, shoes, bags, pens, combs, tooth brushes, buckets, bottles, and water pipes etc.

Plastic as a curse: Problems with plastics arise when we use plastics excessively and are ignorant about ways of disposing their waste. Some common problems with plastics include:

  • All kind of plastics give out harmful gases, upon heating or burning. These gases may cause many health problems, including cancer, in humans.
  • On dumping it in soil, it can block the circulation of air and water in the soil which can kill the organisms living in the soil and hence it affects the fertility and quality of the soil.
  • People often fill garbage in plastic bags and then throw it away. When stray animals look for food in these bags, they end up swallowing these. Sometimes, they die due to this.
  • The plastic bags thrown away carelessly on roads and other places get into drains and the sewer system. As a result, drains get choked and the water spills on the roads. During heavy rains, it might even create a flood like situation.
  • Consuming food packed in plastic bags could be harmful to our health.

Q.17. What can we do to minimise over use of plastics and deal with garbage?

Ans. We should try the following:

  • We should make a minimum use of plastic bags. We should re-use the bags whenever it is possible to do so without any adverse affects.
  • We should insist shopkeepers use paper bags. We should carry a cloth or a jute bag when we go out for shopping.
  • We should not use plastic bags to store eatables.
  • We should not throw plastic bags here and there, after use.
  • We should never burn plastic bags and other plastic items.
  • We should not put garbage in plastic bags and throw it away.
  • We should use vermicomposting at home and deal with our kitchen waste usefully.
  • We should recycle paper.
  • We should use both sides of the paper to write. We should use a slate for rough work. We should use blank sheets of paper left in our notebooks for rough work.
  • We should make our family, friends and others to follow proper practices for disposing different kinds of wastes.

Sound (part -1) class 8

SOUND Q.1. What is sound? Ans. Sound is a form of energy, a sensation felt by our ears and makes us able to hear something. We hear many sounds around us like: sounds of talking, chirping of birds, ringing of bell, fluttering of clothes, machines etc. Q.2. What is the cause of sound? Ans. Vibration in an object produces sound. To and fro or back and forth motion of an object is called vibration. The energy required to make an object vibrate and produce sound is provided by some outside sources (like our hands, wind etc.). For example: We can feel vibrations by keeping our hand on our throat while speaking where vocal cords vibrate to produce sound. The sound of a ‘Dholak or tabla’ is produced by the vibrations of its stretched membrane on strucking. Q.3. Tabulate the Musical Instruments and their Vibrating Parts which vibrate to produce sound. Ans. S.No. Vibrating Part of Instrument Producing Sound Examples 1. Stretc...

A human ear is divided into 3 parts: 1. Outer Ear : It is the only part of the ear that is visible to us. It consists of Pinna, Ear Canal and Ear Drum. The Pinna collects the sound waves and directs them to the ear canal. At the end of ear canal, there is ear drum which is slightly stretched membrane. When the vibrations strike the ear drum, it starts vibrating and transmits the sound to the middle ear. 2. Middle Ear : The middle ear is a cavity with three tiny important ear bones. These bones are M...

  SOUND Characteristics of sound Q.8. Define the following terms: Frequency, time-period and amplitude. Ans. Frequency : The number of oscillations per second is called the frequency of oscillation. Frequency is expressed in hertz. Its symbol is Hz. Time-period : The time period is  the time taken by the oscillating object to complete oscillation. It is expressed in seconds.   Amplitude : the amount of maximum displacement of vibrating particles of the medium from their mean position is called the Amplitude of oscillation. It is also known as size of vibration. The SI unit of amplitude is  the meter. Q.9. A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency. Q.10. The sound from a mosquito is produced when it vibrates its wings at an average rate of 500 vibrations per second. What is the time period of the vibration? Q .11. How c an we differentiate sounds on the basis of their am...
