My takeaways from the Science Fair

-

Four days back,  there was a science fair in my school. The fair was for grades 6 to 12. We could form into teams and present a concept with models and charts. In this post, I will be blogging on my project and the top three exhibits which I liked.

I along with my friend, decided to explore the topic Osmosis. As a result we did the "Bouncy Egg Experiment". We took an egg and soaked it in vinegar for three days. This caused the shell to dissolve and the egg to bounce when dropped from height of around ten centimetres. Everybody liked our project. I loved it when the vistors could not believe their eyes and thought the egg was a plastic toy.
Out of the forty projects in the science fair, I have picked the top three projects which I have liked. Here they are:

1. The science behind the FIFA World Cup footballs
This interesting project by a grade 12 student was on the topic of how the model and design of footballs can make a huge impact especially in big stages such as FIFA World Cups(WC). I got to know a lot of new things through this exhibit. One example is: The Adidas Jabulani(2010 FIFA WC ball) was made from 8 spherical panels and faced a lot of criticism as it would go higher in the air than expected when kicked. The way how the student explained it was amazing.

2. The Sensory Pathway
This project was done by the 10th grade girls. In order to experience it, we had to go in groups of four inside a dark room by closing our eyes. Over there, we had to walk on top of four different surfaces each representing a season. At one point of time we were hit by showers of rain. On opening my eyes, I found out that they used sand for summer, flowers for spring, cotton for winter and dry leaves for autumn. The so called "rain" was actually water being sprinkled on top of us.😂😌 It was an enjoyable experience.

3. The Water Buzzer
A working model presented by my friends from grade 7, this water buzzer is an ingenious way to check the water level in a container. The buzzer is made from a sketch pen and aluminium foil. When water is filled into the beaker, one end of the aluminium foil starts moving upwards. When it meets the other end, electricity is formed and activates the buzzer. This amazed me and motivated me to think more creatively.

Overall, the science fair was really cool and gave me a lot of new ideas. I hope to take part in more such events.😃

Dear all, it is with immense ple a sure I am writing this as it is my 50th blog !! I have been able to cross the Golden Jubilee after exactly seven months and ten days and it has been an incredible journey. I was first introduced to blogging and the world of blogs on 4th May 2018, by my dear father . Making me write blogs was on his radar for a long time as he thought it would help me improve my English writing skills, my observation skills and most of all, helping me organize and structure tasks. When I  started blogging, I would make many errors and my father would diligently and lovingly correct them. But now, I am happy to say that though I make errors while writing, I manage to fix most of them by myself. If you have ever wondered at any point what happens behind the scenes to make my blog, then here you are: 1. Deciding on a topic: Unlike other bloggers, I write about varied topics and deciding a subject is very crucial. I mostly follow a structured order of topics

Our world is being rampaged by the coronavirus(Covid-19) and new personal and social norms have been created in order to prevent the spread of the virus. As we are unsure whether if the virus will be eradicated or the fact that it may continue to remain on earth, we have to equip ourselves for the future in order to be able to live with it. In this blog which is the first of a duology, I will be looking at 3 normal features that we were accustomed to before the spread of the virus and how these features will be reshaped and remodeled in the future. I will also be giving my predictions on what we can expect from these changes in the future. 3 features of the ' Old Normal ' and how they will be modified for the ' New Normal '. 1. Wearing A Mask In Public Prior to the Covid-19 spread, it was not at all necessary to wear a mask in the public. Moreover, people who were sick were only encouraged to wear it. However, it is now made mandatory for everyone to wear a

Why Marketing Is So Crucial For Firms

Why Do Firms Need Marketing? Marketing is for firms what breath is for humans. Generally speaking, the 3 main reasons why entrepreneurs say the reason their company faced heavy losses is because it was either undercapitalized, employed the wrong people or the market conditions were bad. However, I would like to add a fourth point here which is poor marketing. Not only does effective and good marketing help a company sell its product thereby generating revenue, it also helps build indirect customer and business relationships and helps the company gain widespread fame and an increased customer base.  Types of Marketing : 1. Print Advertisements 2. Word of Mouth 3. Radio and Television Advertisements 4. Social Media Advertisements 5. Cause Marketing - Marketing that involves messages about social causes and activist messages 6. Relationship Marketing - Marketing campaigns that stress customer satisfaction more than sales transactions. The Advent of Digital Media Marketing Prior to the bir
