Group 4 Project Day!!

Well, today, our school had a thing called the 'Group 4 Project Day'. Group 4 in IB is the science group, and so today we had to do a variety of science experiments. Needless to ask, our group did one Chem, one Phys, and one Bio experiment.

For our physics experiment, we burnt various nuts and let them burn under a beaker filled with 60mL of water. In doing this, we can see how much energy each type of nut gives off, and determine which one is more fatty for you :P
The results were quite surprising... the least fatty nut was the peanut. Then it was the cashew, and then the almond. The MOST fatty nut was the walnut, so guys, if you don't wanna get fat, then don't eat walnuts!!!
It was quite fun burning the nuts, especially because the burnt nuts gave off this foul odor that made everyone that came into the lab go 'wth???'

The next experiment we did was the chemistry experiment. In this experiment, we put baking soda with various household acids to see how much 'gas' it would produce by using the downward displacement of water method. Because we didn't know the outcome, the first set of ingredients we used were 20g of baking soda, and 100mL of HCL (HCL is the acid found in human stomachs so.. yeah :P). Not a great idea. As soon as I tipped the acid into the flask, even before I could put the stopper on, the bubbles fizzed out of the flask, and after I managed to put the stopped on, the gas still kept on coming out NON-STOP!! The measuring cylinder we used was wayyy too small (it was 250mL, and the volume of gas produced was something like 1L).
After countless attempts to get a feasible and measurable amount of gas, we ended up using only 2g of baking soda and 25mL of acid (see how absurd our first values were? and even at these levels, the gas almost spilled out of the measuring cylinder...).
The most gas produced was when baking soda was with the HCL... (so guys, it is inevitable that when you eat bread, you'll gas). Vinegar and lemon juice produced the same amount of gas, around 90% of that of HCL. But what was REALLY surprising was the reaction with Coke. The reaction only produced like 5% of gas of that of HCL. WTF? So guys, it's okay to drink coke and eat baking soda without gasing up the place, but don't try with any other acids.. :O

Our last experiment, and probably the most anticipated, was the biology experiment. In this experiment, a friend and I had to consume a 'V' energy shot in one go, and then measure the change in heartbeat rate. The initial rate was 63/min for me, and 72/min for my friend.
After 5 minutes, we measured our rates again. My friend's had gone up to 88!!! but mine STAYED at 63!!!!! LOLWUT!!!! We proceeded to take the rates at 5 min intervals for the next 20mins. My friend's went from 88 to 86 to 68 (lolwut) to 82... Mine went from 63 to 64 to 66 to 62... Wth???? Obviously it didn't have much of an effect on me... but... wtf???

Anyways, when we finished all our experiments, it was like 12, and we didn't have anything else to do... so I watched Glee, while everyone went and did their own stuff.
Then everyone started to file in, and soon almost everyone was in the computer room. There, I witnessed Ralph trying to die by eating Mentos and drinking Diet Coke!! Which failed miserably. He then went on to eat some sugar, and also each some rock candy. Later that day, he kept on complaining how he felt bad for eating so much sugar, but I dunno why...

We were all quite bored by then, so we download, YES!!!, Lode Runner!!! The vintage, all time great, 256 colour game for Windows 95!!! LOL (What is surprising is that Ralph was the one that suggested we play games... O.o) we did this got a good 3 hours... :D

Yeah. Nothing much happened after everyone started to go home. I did, though, manage to go downstairs and witness a group of people trying to man up Leo for 30 minutes xP

So yeah that was my day. It was pretty epic IMO... but normal school starts tomorrow... -sigh-==
