In the lab we did today, my partner and I were very confident about our experiment. Unfortunately, we did not get the same number as we had calculated, but my theory is that because I felt the bag get some what heated, my guess is that we lost matter in that it had escaped from the bag when we poured in Chemical C. We possibly did not close the bag fast enough, causing some matter to escape the bag; therefore, not capturing all the possible matter. The reaction was a bit underwhelming, in the sense that we must not have put in enough chemical C, because instead of turning a bright yellow, and becoming squishy, we got a soft, yellow, chunky power like consistency (kind of like Moon Sand, or Squishy Sand); as shown in the photos below.
Measurements and Calculations:
Baggie: 1.9g
Chemical A: 2.3g
Chemical B: 1.9g
Chemical C: 0.5g
total after the product had been measured: 3.7g
our original calculation: 2.8
as you can see from our calculations, we lost approximately 1 whole gram of matter in the 2 second span of closing the baggie.

my element: TIN (Sn)
tin oxide
tin chloride
the two compounds I found are: Tin oxide and Tin chloride. Tin oxide is used as ceramic glaze and was found by a man of the Golinski. Tin chloride does not have a name to its discoverer but it is used in oxidizing materials, and some liquid mixtures and also is used in glass. tin chloride is also used in cosmetic products. I personally like this one better because I use cosmetics enough and now I know what goes in them. 🙂 Tin has a variety of uses and has been used for thousands of years; it was even mentioned in the old testament!
using the rule flower power, which states that “the root goes on the bottom”, it means that the square or cube root of the radical goes on the bottom of the fraction in exponent form. when there is a fraction as an exponent, it also tells you that whatever number is the denominator, is the number representing the root on the radical.
This week I found a connection between the 2 units we learned about. involving radicals, and the term, “flower power” which states that the root goes on the bottom. Seeing radicals in two different units and being used in many ways makes me see that you can use math in many different aspects. Exponents have their own rules, radicals can be mixed or whole, and radicals can even have their own fraction as the exponent. Below is an example of “flower power”, and the fractions as an exponent in a radical.
WHAT FUELS THE HUMAN NEED TO CONFORM?
In Harrison Bergeron, it shows a good example of the need to conform, with the handicapper general changing everbody’s abilities in order to make everyone equal. The desire to have an equal society comes from the natural human need to compete, and some people may find competition a negative desire, when in reality, it can be good, because it makes us want to better ourselves. Not always bad, like to put people down, but to make us better. I don’t like that when someone says they are competing they automatically assume its to put people down, but not to compete with ourselves or to gain a better title. Here, competition is eliminated completely. The beautiful are covered in masks, the strong are weighed down, and the intelligent are permitted to wear transmitters sending terrible sounds every 20 seconds or so, in order to prevent deep thoughts and unfair advantages with their brains. this law was permitted by the “unceasing vigilance of agents of the United States Handicapper General.” So the need to conform comes from the negative portrayal of competition. There is also the fear that if you are different, then there is harsh judgment that goes along with that, so we tend to be stand off-ish. But when there is a spark that makes us want to better ourselves and compete, why should be taken away? Deal with the fact that someone might be better at something than you. This message is very clear to me in the story. This to me means that the HG is not equal to everyone else because the book implies that the HG has no handicaps herself.
I find this picture resembles the story because it shows that when everyone is the same, there is always one person in power (HG). This means that everyone is NOT in fact equal, and there for creating the mild competition, which, if I remember correctly, if the REASON for making everyone the same? Who decides the base line for average? Who decides who need more handicaps than that other guy? All these questions are unanswered but nobody has the brain capacity to ask them.
Element: Tin
Atomic Family: tin is a transition metal in the carbon family
who discovered it? why/how?: who: UNKNOWN.
uses: used in alloys like bronze, useful for non rusting equipment. also is used in making weather resistant windows.
interesting…: Tin (Sn) has a natural resistance to oxidization
this is the equation on another skills check I did, after wanting some more practice with this type of question.
this week it was another “ah-ha” moment. this time it was with the Pythagorean Theorem and solving for “a” “b” or “c”. at first I didn’t know how to solve these, then I thought you had to add everything up in the end, but it is really like any other equation. when you are solving for “c” you have to follow the equation a^2 + b^2= c^2. BUT if you are solving for a or a or b, then you have to subtract c from the other given number. like this equation I did here (and got right!)
for me, week 1 was filled with a late ah-ha moment. my moment was when I understood how to convert mixed radicals into entire radicals. It’s as easy as multiplication! here you see a photo of what I mean…
For me remembering how to do this was quite the achievement because normally I don’t remember how to do everything after class, but here I remembered and got the questions right and I was super happy about it! All I did to help me was put in the invisible 2 as the exponant, and in just visualize it as a multiplication question and I get it right.
