Alarms and it’s types 

               Alarms are used to alert people to potential danger. However, they are useless if people don’t recognize the alarm and know what it means. They should know how to respond to a particular alarm. Whether it is a family function, a school, or a place of business, an alarm should be in place to alert people. These days, most alarms are electronic in nature and it helps to understand their components and functionality. In this article we will look at that and also some types of alarms.

Components of alarms:

Electronic alarm systems are made up of components designed to detect, determine and deter threatening situations.

  • Motion Sensors:

    They can detect movement in a room or a corridor.


Motion Sensors

  • Glass Break Detectors:

    They are designed to constantly listen for the sound of breaking glass. When it detects the sound pattern caused by shattering glass, it sends an electronic signal to the alarm control panel.

  • Shock Sensors:

    They can detect an intruder who is using force to pound through a wall or any area of a structure.


Shock Sensors

  • Keypad:

    Keypad is used to arm and disarm an alarm system. They are generally installed near the entrance or exit of a building.




  1. Carbon Monoxide Alarms

Carbon monoxide is an odourless, invisible gas that can lead to poisoning. These alarms use electro-chemical sensing technology to alert you.

  1. Burglary

A thief breaks the glass of your shop! Instantly a high pitched wail sounds in the air! Almost every house or shop abroad has burglar alarms. Unfortunately, the practise is not very common here in India.

  1. Fire

Smoke and fire alarms warn people of the presence of fire in a building. Some alarms have the feature of alerting the nearest fire department. Many places, such as schools and college dormitories, perform drills to practice what to do in case of a fire alarm.

  1. Flood

It has nothing to do with warning you of the infamous Mumbai floods. Water damage from a faulty water heater can be just as damaging to a home as a fire. Flood alarms sense the presence of water and can be programmed to shut the water off when it is nearing a flood zone.

  1. Weather Alarms

U.S faces tornadoes, hurricanes and horrific forest fires every year. It is extremely important to be able to recognize alarms that warn of severe weather. Many cities have public alarm systems that sound informing people to take shelter. The National Weather Service issues severe weather warnings through television and radio broadcasting systems.

2. Tesla Model S

If you are looking for the toy of the decade, take a look of this Tesla Model S for kids version, the company officially helped to make a reality. It seems to be

a miniature version of the classic electric car to the details and hence, according to the website the price is 499$.

3. Water Wheel

By giving people easier access to potable water, the Water Wheel frees up valuable time, and in the process, most likely removes barriers that prevent children from going to school and empowers women to engage in more productive activities. Research shows that when women have extra time, they choose to spend it on activities that boost family income, education, health, and well being. Women with even a few years of education have smaller, healthier families, and are more likely to send their children to school. Female education is a key means due to of breaking the cycle of poverty.

Presentation ideas on school projects basically provides material and ideas for school science projects.

The idea behind the presentation most of all remains the same from elementary to middle school.

Therefore, we are mentioning step by step methods for school projects in the best way possible.

STEP 1 : Select a category for your school science project

Many science topics come under one single category as in sub categories.

For example, topic of renewable energy is one category of science.

STEP 2: Researching the topic for your school science project

The hardest part is to select a topic for your science project or, science fair. The easiest way to go through the process is researching maximum information in addition to finalizing the topic for science project.

The problem, the hypothesis and the experiment hence is the other part of researching the topic.

STEP 3: Finding the problem for your school science project

Your science project should basically solve any problems of the real world and ask queries on existing. The problem statement is the statement which defines the problem through your science project would be dealing within.

STEP 4: Project hypothesis for your school science project

The predictable solution to the problem probably seems to have been understood using Step 3.

STEP 5 : Designing the experiment for your project

Designing the experiment is the method or, the way with which you will find solution to the identified problem.

STEP 6: Data collection of your project


data is the result from the experiment being conducted for school science project. Once the raw data is collected it can be presented in a science fair using graphs, pie charts.

STEP 7:  Designing project display

Designing and presenting project display is important and critical either for evaluator or, assessor to review the school science project first of all in a step by step way.

All the information collected for the science project should display with a brief summary about school science experiment project.

An oral and brief presentation during the display also helps.

The best part in a science fair or, school science project is to create something and doing research about the topic. The objective should be to invent new areas in science instead of reading science text books.



When I was in middle school, I was an average student, but my weakest point was maths. Scoldings or encouragement nothing could change it so my mother reflects even today. With a tonn of cousins going places with amazing math results, i thought it will always remain a mystery to me.

Choosing of Subjects especially math

When it came to choosing subjects in high school, I made sure maths was nowhere near me in any way possible even though I enjoyed physics and solving little less tricky theorems.

I wish someone had told me at that time that maths is not about eating all your green vegetables or a gift which I seemed to have lost when

http://www.viagragenericoes24.comit came to me even though I had good share of relatives and solving and acing all the scary math sums. I thought “I simply did not had it in my DNA’. Hence the medical profession and I cheered myself through as I thought I was done with maths forever.


I didn’t flunk any of the exams but I could not muster even average score, even though I made sure my other subjects covered for my shortcoming. I wish someone at that time had told me that maths is all about perseverance and not about what kind of math genius brains you have.


Studies have shown that students who spend more time at solving mathematical queries are better at it than those who give up. soon. We forget all the time that maths is an activity you learn by doing instead of mugging it up. The whole point being you are never born a maths genius, you eventually become one by doing things regularly and keep doing them and not giving up. Working hard is what makes the difference.

Talking to your child about it and keep going at it will surely make the difference. It’s just simple; you do not give up on your child so that your child does not give up on mathematics.

Remember if I knew that it’s not that you need to be a maths person to learn maths “I would have ended up differently, if only my parents had the information and the technology we have today” says Dr. Naina Arora from
