Effect of video games on human body

Hey all of you gamers out there! Do you ever feel a rush of adrenaline and a sense of intensity whenever you play video games? Why do we feel so immersed and focused whenever we play video games. That is just the question we are yet to answer.

To find the truth behind this sensation, the High School Science Club set out and begun a research experiment on different age groups,  ranging from high schoolers (16-18 years old) and adults (50-55 years). Each volunteer was asked to play two different games which had varying genres meant to have different levels of focus and skill needed. Each volunteer had their heart rate, blood pressure and pain tolerance measured before, during, and after playing to see if playing video games really did have an effect on the human body. Blood pressure and heart rate were monitored using a digital monitor tied on the wrist. Pain tolerance was measured by pricking a pin several times on their arm and recording the counts they sensed. The measurements were compared to their resting state observations.

Line graphs were plotted for all the parameters to have a comparative insight of the variations. Some sample graphs have been shown herewith. The data evidently represented that all the tested parameters show higher variations during the test conditions as compared to the resting stage (control condition). Also, it was clearly noticed that volunteers in the teens group showed higher fluctuations in their heart rate and blood pressure while the older volunteers tend to have more stability in their basic parameters. This may also be attributed to the varying interest levels in people of different age groups.

Though the data was divergent for different volunteers, making it inappropriate to quantify the results as an average effect of video games. But overall trend in the data suggests, that there is a significant fluctuation in your heart rate and blood pressure along with a decrease in your pain sensitivity while playing video games.  Even though your body isn’t actually moving when you play video games, adrenal medulla gland releases hormones and adrenaline due to the amount of focus paid to the game. Some effects are also visible like dilation of pupils to enhance focus for the game.

It can be concluded that a prolonged use of such games, may result in severe complications. These blood pressure variations may be mild for the moment but may have a long term effect on the body. So, we must advise young generations to use these activities only for leisure rather than an addictive routine.

Teeth Whitening Wonders – Part 2!

Revolutionary Science in the Palm of our Hands

Based on the results of the previous experiment conducted on seashells, the High School Science Club has decided to proceed and conduct its newest experiment. Thanks to the contributions of a few dentists however, we were able to conduct our experiment on real human teeth. The aim of this experiment, just like its precedent, is to discover which chemical is most effective in teeth whitening. Interestingly, these experiments supported the results obtained by the earlier experiment. Again, tea was found to be the strongest staining agent whose stains were most difficult to remove. Amongst the toothpastes, Signal again has proven to be the most powerful whitening agent, as the results were much better visibly compared to the other toothpastes (Colgate and Crest). Due to limited teeth samples however, we were not able to continue the study with natural remedies (banana peel and baking soda + lemon), which were found to be as equally effective as toothpaste. Nonetheless, we believe that these results would also have been replicated, like the remaining others. This experiment also supports and validates the use of seashells in teeth-related experiments since they produce the same results. In a nutshell, our experiment concluded in a huge success, since our expectations and theories were in fact reality.

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.
