Discover it for yourself!

This is quick post on my experience at the holiday Scilab camp at office today. Yesterday, I was demonstrating concepts of Newton’s laws, air pressure and the Joule-Thomson effect with balloons. At the end of the session, a couple of them (10 year olds) approached me and asked me if there is anything more that can be done with the balloons. I gave them each a couple of balloons and asked them to discover it for themselves.

This morning, both of them came to the camp and reported their results to me. One of them had blown the balloon till it exploded. When I asked him as to what he learned, he told me that he was able to understand that the rubber balloon had a certain amount of strength and the excess amount of air pushed it beyond its limits causing it to burst. He has just discovered the phenomenon of tensile strength for himself! The other told me that he had tried filling the balloon with water and placing it in a bucket of water. He said that he was surprised to see the balloon bobbing upon the surface of water. He has just discovered the phenomenon of buoyancy for himself!

Their observations were remarkable and following a round of applause, we spent the next 20 minutes discussing their results. It will be quite hard for them to forget the concepts which they have discovered for themselves.

This is a cross post from my blog.

About eshwaranv

Hello there! This is Vytheeshwaran Vedagiri from Chennai, India. I am a Chemistry/biology teacher by choice. I became an online tutor right from my college days for students from the US and UK. I started my Web site http://biochemistryforu.googlepages.com for the same. After completing my Post graduation in Biochemistry, I became a full fledged online tutor. During this time, I was invited by a company to develop content for their textbooks. This took me into a whole new world of educational content writing (creative writing). For the first time, I was given a chance to create something new and I loved it. After that, I started working on developing asynchronous digital content for a private company. At this point of time, I was introduced to instructional designing by my friend and I'm ever grateful to her for doing that. I've just begun canoeing into the estuaries of ID and hoping to sail upon the ocean of ID in the near future. To sum up, I'm an online tutor, an SME and an instructional designer. You are free to comment and interact with me on my posts.
