Experiment 7 Chemistry Lab Answers

[Shanel Arrendell]

ProductThe Sims 4

Platform:PC

Which language are you playing the game in? English

How often does the bug occur? Every time (100%)

What is your current game version number? 1.105.345.1020

What expansions, game packs, and stuff packs do you have installed? All.

Steps: How can we find the bug ourselves? Experiment with the Chemistry Lab. My sim was using it during a work shift on the Scientist work lot.

What happens when the bug occurs? The sim gains the Gemology Skill and does not gain the Logic Skill.

What do you expect to see? I expect to gain the logic skill, not the gemology skill.

Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.

Did this issue appear after a specific patch or change you made to your system? Yes

Please describe the patch or change you made. Crystal Creations.

can you please attach some photos of what exact interactions you are using on the table and show what skills are being gained? I know some interactions can build 2 skills together, but will only show 1 icon above the sims head. If you look in the skill panel, can you see the logic skill gaining from there?

This sounds more like a design change than a bug. I don't think it really makes the Scientist career more difficult, though, because the career doesn't require Logic skill. Scientist promotions are based on breakthroughs, not skills, so it shouldn't make any difference which skills you learn.

I don't work or have any association with EA. I give advice to the best of my knowledge and cannot be held responsible for any damage done to your computer/game.

Please only contact me via PM when asked to do so.

@crinrictI think this is because the actions (al_ChemistryTable_Experiment_Actions) during the chemistry lab experiments (si_ChemistryLab_Experiment) are related to finding metals, and finding metals in stones increases gemology.

For example, mixer_ChemistryLab_AddChemical links to loot_ObjectReward_Collectible_Metal. I don't know if this is a bug, or if it was intended.

I got a chemistry set as a kid in the early 1970s, and the subject really captured my interest. I grabbed every chemistry book I could find from our libraries. They ranged from college textbooks to "Chemical Magic" collections of demonstrations. These latter tended toward pyrotechnics, and were pretty appalling safety-wise.

There were several favorites, but there was one book in particular that stuck with me, found in a rural Virginia county library around 1976 or so. It featured adolescents in coats and ties (and maybe one in blouse and skirt) demonstrating experiments, but the experiments were a couple of levels beyond what I found elsewhere.

There were probably a dozen or so others. I think one involved generating chlorine gas from an aqueous solution in the bottom of a beaker, then dropping in pellets of calcium carbide to watch the acetylene spontaneously combust.

I've searched using Google, but can't seem to get past The Golden Book of Chemistry Experiments -- yes, that's another treasured memory from the time, but it's not the one I have in mind. (For one thing, the one I'm asking about had no color plates at all.)

Another near miss that's quite familiar to me is Leonard A. Ford's Chemical Magic (I remember the 1959 original). I don't have it in hand, but Google's preview let me read far enough to see familiar material -- including pyrotechnic mixes using potassium chlorate instead of perchlorate, which got me in no small amount of trouble some years later. The book I'm searching for was more oriented toward science, rather than showmanship.

If the book I've described sounds familiar, please post an answer with any additional information you find -- title and publisher would be great, but additional experiment descriptions would also be helpful. If you have a favorite book from that period that doesn't seem to match this description, I'd be interested in hearing about it as well.

There are 2 books in German which inspired me to become Chemist. I had them in the late 70s."Chemische Experiemnte, die gelingen" (Chemical experiments which succeed) and "Organische Chemie im Probierglas" (Organic chemistry in a test tube). Both published originally in 1939 by Hermann Rmpp and Hermann Raaf. Kosmos Verlag (Kosmos Publishers). No idea if there ever were English translations, but you might still find them in antiquary bookshops.

I've found the book! It is Chemical Magic, by Kenneth M. Swezey, McGraw-Hill, 1956. All the experiments I remember are there. There are quite a few others that I'd done, but forgotten finding in this particular book.

Thanks to those who offered help, and I invite anyone interested to take a look through these books. I do miss the days when it was conceivable for a schoolchild to work with "dangerous materials" (never mind "drug precursors")...

Several seminal experiments in this topic have been conducted at the University of Chicago, including the Miller-Urey experiment that suggested how the building blocks of life could form in a primordial soup.

Earth is about 4.5 billion years old. Scientists think that by 4.3 billion years ago, Earth may have developed conditions suitable to support life. The oldest known fossils, however, are only 3.7 billion years old. During that 600 million-year window, life may have emerged repeatedly, only to be snuffed out by catastrophic collisions with asteroids and comets.

Organic molecules may also have formed in certain types of clay minerals that could have offered favorable conditions for protection and preservation. This could have happened on Earth during its early history, or on comets and asteroids that later brought them to Earth in collisions. This would suggest that the same process could have seeded life on planets elsewhere in the universe.

As a University of Chicago graduate student in 1952, Stanley Miller performed a famous experiment with Harold Urey, a Nobel laureate in chemistry. Their results explored the idea that life formed in a primordial soup.

In science, the definition of "error" is not always the same as in normal language. An error in chemistry may still be a mistake, for example reading a scale incorrectly, but could also include normal unavoidable inaccuracies associated with measurements in an experiment in a lab.

Using this definition of error, there are many possible different sources of error in an experiment or scientific process. In fact, the result of a chemical experiment may never give a definitive answer due to the number of possible errors and the result is usually a statistical approximation of the absolute answer.

Another area where chemistry and general conversation differ is the use of accuracy and precision. In Normal conversation these two words are interchangeable but in analytical chemistry, they have different meanings:-

Interpretation of experimental results requires some mathematical knowledge and the sensitivity of instruments and processes. An understanding of significant figures is often required. For example, if you are measuring the length and your instrument can read to the nearest millimeter and a calculation gives a figure to micrometers the significant figure is millimeters as there is no way of measuring smaller distances accurately.

When interpreting multiple results the values can be reported as the mean or the median. The median is the middle value and the mean is the arithmetic average. An outlier value may cause an error where an outlier is a result that is significantly different from all the other results. This could lead to a gross error being reported. The relative error can be calculated by taking the actual value minus the measured value and dividing it by the actual value and is usually expressed as a percentage.

Multiple experimental results can also be analyzed us Gaussian standardized normal curves where one standard deviation will contain 68% of results and two standard deviations will include 95% of results.

In summary, it is very unlikely that a chemical experiment will give the absolute answer. There will always be some element of error in the result. If the error is determinate it can be minimized or eliminated but indeterminate errors will not necessarily be known. The job of the chemist is to minimize or compensate for the errors to get an answer that is accurate as possible using suitable mathematical and practical strategies.

Chemistry labs often involve various equipment, chemicals, and processes that can be potentially dangerous. Adhering to safety guidelines reduces the risk of accidents such as fires, explosions, chemical spills, and burns. Proper storage, handling, and disposal of chemicals, as well as the use of personal protective equipment (PPE), help prevent accidents from occurring.

Chemistry lab safety practices involve identifying potential hazards associated with chemicals, equipment, and procedures. This includes understanding the properties of chemicals, their reactivity, and potential health effects. Conducting risk assessments helps in identifying potential risks and implementing necessary precautions to mitigate them.
