Math Behind the Ferris Wheel

The next time you decide to drive out to the Amusement Park, make sure you pay the Ferris Wheel a visit. This entertaining ride will make you ponder about how such a colossal moving structure was built. You will realize that the Ferris wheel is much more complex than it seems to be. We, the FST Class, explored, analyzed, and identified the complex mathematical procedures required to build a model of Ferris wheel, calculated the height of the seats within the model aswell as applied the concept of unit circle trigonometry by making a periodic situation. The team, consisting of Judy El-hassan, Abdul Hannan, Mina Samy, Hayoung Lee, Nour Tareq, and I, collaboratively worked and carefully initialized the construction of our Ferris Wheel. In order to make 12 equidistant spokes, we needed a consistent rule to follow. Therefore, we idealized the unit circle and transformed the intervals in terms of pi and marked them on the cardboard carefully. We repeated this for all the 12 spokes to ensure that our Ferris Wheel was error-free. We also remeasured the distance to ensure it was identical.

It takes vital practice, thought, and application to build a perfectly round structure able to withstand constant circular motion and weight of amusement park riders. Behind every structural component in the Ferris wheel is a purpose, and that is what we aimed to portray whilst building our model. We can now safely say that we have successfully constructed a realistic model for the Ferris Wheel and have completely understood the different mathematical applications performed to build such a wonder. Applying mathematics into forms of amusement has never been more intriguing.

Teeth-Whitening Wonder

Revolutionary Science in the Palm of our Hands

   The food and drinks we consume everyday have a very harsh effect on the appearance of our teeth. Most, if not all, of us must have noticed that they are staining them. Recently, white teeth have become more and more favorable among the masses.  People are looking at the quickest teeth-whitening methods to achieve these results. The High-School Science Club  decided to perform an experiment by staining shells, because they have the same composition of our teeth; with different staining agents such as coffee, tea, and soda. After a week of staining, we tested some of the most common teeth-whitening techniques, both natural and chemical, to see which ones have the most effective impact on removing these stains. Studies of previous whitening experiments led to the conclusion that using bleach or products that contain hydrogen peroxide were the most effective methods. We took some of the most popular toothpastes (Signal, Closeup, Colgate) containing small amounts of hydrogen peroxide, and some of the most prevalent natural remedies (bananas, baking soda and lemon).

   We experimented to find the strongest stainer and the overall best mechanism to remove those stains. In our results, we were able to conclude that tea was the strongest stainer, unless washed directly after consuming. Natural remedies also removed almost all the stains. However, Signal was the toothpaste that made the greatest change. With the cumulative data we acquired, the same experiment will be conducted on human teeth to see if they yield the same result.
