COVID 19

THE SPREAD OF CORONA VIRUS...

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered corona virus. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

 The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes. At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments. 

You can reduce your chances of being infected or spreading COVID-19 by taking some simple precautions:

• Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap                                                                            and water. 
• Maintain at least 1 metre (3 feet) distance between yourself and others. 
• Avoid going to crowded places. Where people come together in crowds, you are more likely to come                                                                      into close contact with someone that has COIVD-19 and it is more difficult to maintain physical distance of 1 metre (3 feet).
• Avoid touching eyes, nose and mouth.Hands touch many surfaces and can pick up viruses. Once                                                                          contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and infect you.

ROLE PLAY - VITAMINS AND MINERALS

VITAMINS AND MINERALS (Role play)

Role play is any speaking activity when you either put yourself into somebody else's shoes, or when you stay in your own shoes but put yourself into an imaginary situation! Imaginary people - The joy of role-play is that students can 'become' anyone they like for a short time.

 Role play in science is a combination of the use of drama, games, and simulations. Since role play is based on play, it can help students to make science more relevant to their lives. Moreover, role play allows students to both express themselves in a scientific context and develop an understanding of difficult concepts. It also encourages creativity and imagination. Pretend play helps children naturally develop and use their cognitive abilities and skills. Through using their imagination regularly, they develop creativity and learn to think for themselves.

As part of B.Ed curriculum we prepare and presented a role based on vitamins and minerals. 

National science day

NATIONAL SCIENCE DAY

National Science Day 2020: This day is celebrated every year on February 28 in the country to celebrate the discovery of the ‘Raman Effect’. India’s great scientist CV Raman invented the ‘Raman Effect’ on this day and won Nobel Prize for the same. The great physicist Sir Chandrashekhar Venkat Raman made an important discovery in the serious subject of physics on February 28, 1928. Now, the Government of India felicitates scientists every year on this day who contributed to the field of science.

Theme of National Science Day 2020: This year, the theme for National Science Day 2020 is "Women in Science", which aims to appreciate the contribution of women in the field of science.

Projected aids

 ASSIGNMENT

ON PROJECTED AIDS

Submitted by,

VIJI MOL. M. V

Christ Nagar College of Education

1.INTRODUCTION

Projected aids are much helpful in the teaching learning process. So teachers should know about these aids is very essential in the present situation. Projected aids can give first hand experience by looking at concrete thing, living specimen, handling apparatus, and actual demonstration, etc. It motivates students mental and physical activity and time consuming. Projected aids are very helpful to bring a change in the atmosphere in the class. It makes learning effective and durable. By referring books and websites we can gather information about projected aids.

(Online.WWW.Slideshare.net)

2.PROJECTED AIDS

Projected aids include slides, film strips and film. The projection of these aids involves various types of equipment beginning from the simple magic lantern to the complicated sound film projectors . Projectors can be of three types:

(1) Direct projections

(2) Indirect projection

(3) Reflected projection

3.ADVANTAGES OF PROJECTED AIDS

1. A large group can study picture at one time
2. Magnification is possible which often helps the audience to get across an idea by presenting more details.
3. Original pictures can be reproduced to make several sets available simultaneously
4. Concentrated attention can be expected when visual distraction in the room are moved because of dark room
5. Film, strip, slides etc can be easily be stored and if handled with care, can last quite long.

4.DISADVANTAGES OF PROJECTED AIDS

1. The equipments are very expensive
2. Equipment are not available all over the country.
3. Lot of upkeep and maintenance is required continuously for the equipment, which is often difficult to provide, Specially in smaller cities and towns.
4. Projection is a group technique and , therefore, may not allow enough time for individual study
5. While projecting , the room has to be made dark and therefore, the people can’t take down notes.However it can be overcome by fitting overhead light focusing on individual desko.

5,PROJECTORS

5.1 OVERHEAD PROJECTOR (OHP)

This is a device that can project a chart, a diagram, a map , a table , anything written on transparent plates upon a screen. This makes the screen illuminative and impressive. It also saves a great deal of the teacher time used in drawing or writing them. These transparencies can also be preserved by the teacher for future display while taking up the same topic.

It uses the principle of indirect projection. In this, the projected image is obtained behind and over the head of the instructor. Making use of lens of short focal length and two mirrors to reflect the picture on the screen , the overhead projector can be placed in front of the groups. It shows transparencies of slides of 18”x 10”’ size.

Normally overhead projectors are composed of a projection lamp to act as a source of light, condensing lenses to concentrate all the light into usable beam, a polished mirror and lens assembly and a blower for cooling the system. OHP should not kept on continuously for long periods.

5.1 (1) Advantages of OHP

1. A large image in a minimum projection distance is obtainable.
2. Permits the instructor to face the class as he writes or indicates points of importance on the transparency.
3. Projected image obtained could be seen even in a lighted room.
4. Simple and convenient to operate the equipment.
5. Flexible material can be prepared easily by different methods. It can be used in different methods. It can be used in different ways for writing and presentation of charts etc.
6. Transparencies are securable.

5.1 (2) Disadvantages of OHP

1. The projector is expensive and cumbersome.
2. It requires electricity, special pen and acetate or plastic transparencies.
3. Spare parts may be difficult to obtain and expensive.
4. Light from the projector in the trainer’s eye may be unpleasant.

5.2 L C D

Liquid crystal display (LCD) projectors usually contain three separate LCD glass panels , one each for red, green and blue components of the image signed being fed into the projector. As light passes through the LCD panels, individual pixels can be opened to allow light to pass or closed to block the light , as if each little pixel were fitted in a venetian blind. The activity modulates the light and produces the image that is projected onto the screen. And for larger conference rooms that require higher light output and greater connectivity. LCD technology holds a commanding lead.

5.2 (1) Advantages of L C D

1. It has historically delivered better colour saturation than from a DLP projector.
2. It also delivers a somewhat sharper image than DLP at any given resolution.
3. LCD is more light efficient ie, LCD projectors usually producers significantly higher ANSI lumen outputs than do DLP’s with the same wattage lamp.

5.2 (2) Disadvantages of L C D

1.Visible pixilation or “screen door effect” because it looks like you are viewing the image through the screen door.

2.Lack of impressive black levels and contrast , which are vitally important elements in a good video image.

3. Long term image degradation.

6. CONCLUSION

Projected aids make learning more permanent. They offer a reality of experiences which stimulate self activity on the part of pupils. Develop continuity of thought; this is especially true of motivation picture. Overhead Projectors and LCD are the most widely used projected aids. They have high degree of interest for students and help to develop scientific attitude and get a training in scientific method. It is one of the most convenient, easy and natural way of learning.

Environmental problems

 

Top Environmental Problems and their Impact 

Our planet is plagued by environmental problems that deplete natural resources and strain livelihoods, many of which are exacerbated by poor industrial practices. If left unchecked, environmental problems negatively impact businesses both directly, as in supply chain disruptions, and indirectly, as in health hazards that lead to loss of man-hours and efficiency. Following are some common environmental problems

Pollution

Pollution is one of the world’s biggest environmental problems, as it tends to be a typical byproduct of modern life. Air pollution, for instance, is the result of fossil fuel combustion, as well as various gases and toxins released by industries and factories.

Waste Disposal

As populations and industries grow, so does the problem of proper waste disposal. Communities accumulate so much garbage that properly disposing of it has become increasingly difficult. Solid garbage, for example, is usually buried in landfill sites or incinerated, which is extremely harmful to the environment. Decomposing garbage may attract vermin, give off a foul smell or leach into groundwater. The smoke given off by burning garbage contributes to air pollution.

Climate Change

In his encyclical Laudato si , Pope Francis urged action on climate change, warning that climate change is real and a problem that we can no longer afford to ignore: “Climate change is a global problem with grave implications: environmental, social, economic, political and for the distribution of goods. It represents one of the principal challenges facing humanity in our day. If present trends continue, this century may well witness extraordinary climate change and an unprecedented destruction of ecosystems, with serious consequences for all of us.”
