Acid in your stomach lab!

    Usually when you've eaten something that has your stomach turned upset down, you always want something to cure this. Most result to the oh so popular Tums. The hypothesis my group had was that both generic version and Tums would both work in the same way, and perform evenly. With the help of vinegar, the original and generic Tums, beakers, pH papers, a grinder, and coffee stirers we were able to reenact how it would be like in someones stomach.

What we did was pour vinegar into a beaker, with that we then used the pH paper to determine what level it was at(2). During that time we were also crushing up the generic tums so we could then put them in the beaker filled with vinegar. Two tablets was considered the lowest recommend dosage you should take. So with that being said we had four tablets. Two being the generic anti acid brand, and two being the original Tums. After putting the generic kind in the beaker, our result was that it fizzed, and bubbled up. It also had the pH level of 7. We did it again with the original brand and the result reoccurred from the previous experiment.

Waterrrrr Lab! :)

In this lab, we experimented with alcohol and water. We put water on wax paper, and it was very interesting that with a toothpick you can pretty much cut through it and separate it. We were determining what water was. As well as how it sticks together, or can be apart.  I learned that there are other properties of water other than being just the casual clear color, or the common feeling of it. Water is capable of sticking. Another thing that happened in the lab was that we tried to pour water down a string into another beaker. With that being said, it probably sounds unrealistic. Wrong. You just need to know exactly how to do it. What you did was wet the string to stick with the other water that was being poured down. And WA-LA, you have it.

Corn Lab

    This experiment was basically about how the scientific method can be used in several different ways. Its used over and over again, but in different ways, and in different orders as well. Its basically a mess, and scientist constantly have trial and error, which relates to the corn lab. It was to show you that you had to do a lot of different things in order to receive the result you wanted.  Around fifth grade is when I was exposed to the scientific method, there I was new to it all, and often confused. But as soon as I was able to understand it a little more as the years passed, I now see that it's not always going to be those steps exactly. This lab taught me that the scientific method is more of an investigation and you can process it in different steps.
       A little more in depth with this experiment, I would like to add that during the time of using the corn lab, you needed to know that on one side was a good growing corn, and the other was infested. You would put the corn to grow (which were both different corn, one was Bt 123, and BT 456) , along with the other variable being some type of bug, ECB (European Corn Bugs) . Either way, while testing it, you realize one crop of corn does not grow healthy. The virtual experiment showed me what anger, and the processes the scientists are open to.
    From the lab I learned that you can't always use the scientific method word for word. This is because scientist don't always follow it and they have to do it several times before things work out exactly how they would like them to.
