Science Fair 2018

Boys participated in MSEF Region VII Lower Science Fair at Ole Miss.  Arjun won 2nd place in the category of Physics and Astronomy and Kabir won 1st place in the category of Engineering.  Also, Kabir’s project has been nominated for Broadcom Masters.

Arjun’s project was “Morse Code: Is it Still Useful in the Modern World?

The abstract of his project was:
Morse code is a form of communication made up of dots and dashes that grew popular in the 1800s. I wanted to know if Morse code was still useful in the modern world. I hypothesized that Morse code could still be used as a tool of communication. I created a telegraph and sent the same message to seven different people. I observed the time taken to send and understand the messages, and the accuracy of the sent and recieved messages. The original message was the word “AMERICA.” After performing this experiment and analyzing the results, I concluded that Morse code can still be used as an effective tool of communication, although text messaging is much faster and more accurate. However, Morse code can still be used by hobbyists and for fun (like sending secret messages to friends). Also, if people find themselves in an emergency situation and they don’t have modern means of communication, they will still be able to communicate using Morse code.

 

Kabir’s project was “Which Air Foil Creates the most Lift?

The abstract of his project was:
I asked a question: Which airfoil, or wing design, creates the most lift? I experimented with the shape of the airfoil, changing the upper and lower cambers, or curves, for six different wing designs. This was the only variable I tested. I hypothesized that the Thin Deep Camber airfoil would create the most lift. The Thick Deep Camber would be second, and the Low Camber would be third. The GA(W)-1 airfoil would be fourth, and the Symmetrical airfoil would be fifth. The Low Lift would be next. The plain block would create no or very little lift, putting it as the least. I researched and learnt about the forces of flight (lift, weight, thrust, and drag), the Bernoulli Principle and the Coand? effect, wing shapes and airfoil designs, and more. Then, I gathered my materials and conducted my experiment, which involved making airfoil templates, tracing airfoil designs onto styrofoam blocks, and using an electric foam cutting pen to cut out the airfoil. I repeated this for the other five designs on the remaining blocks. I used a fixed wind source and a weighing scale to find the lift (in grams) created by each airfoil design. My results showed that the Symmetrical airfoil created the most lift, followed by the Thin Deep Camber. Therefore, I concluded that my hypothesis was incorrect. However, there were several technical limitations to my experiment that may have affected the final results.
