Transcript: RNK Presents: BOILER ALERT: THE Experiment By: Andrew R, Philip N, & Chris K THE QUESTION Which liquid has the lowest boiling point? THE LIQUIDS 1. water 2. vegetable oil 3. vinegar THE VARIABLES Manipulated Varible: The different liquids Responding Variable: Temperature where liquids boil Controlled variables: Amount of liquid, Increased temperature rate THE HYPOTHESIS If different liquids are increased in temperature at the same rate, then water will boil in the lowest temperature. THE MATERIALS •Boiler •Teapot • Water •Vinegar •Vegetable Oil THE PROCEDURE 1. Put 200ml of one liquid into the teapot 2.Put teapot on boiler. 3. Set boiler on high. 4. When bubbling, record temperature and time it took. 5. Reapeat for the rest of the liquids. Vegetable Oil took 3:36 to boil and boiled at 52 degrees celcius. Vinegar took 5:10 to boil and boiled at 81 degrees celcius THE CONCLUSION Something that we could've performed more accurately was starting and stopping the stop watch at the correct time. This could be performed more accurately by paying better attention to the liquid and the stopwatch. Another experiment we could perform would be testing the density of the liquids and comparing that to the boiling point to see if there was any connection. As you can see, the liquid molecules are spread out, but not as much as gas molecules. The gas molecules are even more spread out than the liquids. This is what the molecules looked like after the liquid was boiled. Water took 4:15 to boil and it boiled at 80 degrees celcius. Vegetable Oil took 3.36 to boil and boiled at 52 degrees celcius. Our hypothesis that the water would boil at the lowest temperature was incorrect. Our data shows that the vegetable oil boiled at the lowest temperature. Responding Variable: Temperature where liquids boil THE RESULTS

Human Sciences John Nash Nash equilibrium Situtation where no one loses Ethics Progress for the sake of progress, is another way of saying that we need to advance in technology just because we have the means to do so. Is an older student ethically responsible for exposing the lie that his paren't told him, to help in his pursuit of knowledge? What misconceptions do we have about theories vs. proven facts? or the Mayan Calendar where we learn that some people will make the wildest claims to get on the news "There is one not-so-tiny flaw in all of these theories for the increase in mass shootings, and that is that mass shootings have not increased in number or in overall body count, at least not over the past several decades." -The Los Angeles Times Many people dismiss Global warming as just a theory, the same as if if you or I were to hypothisize whether it will rain or not tomorrow. The difference between a colloquial theory and a scientific theory is that to be considered a scientific theory, 95% of the scientific community must agree with the statement. One problem that arises is that of industry: all factories that can help a developing country progress are harmful to the environment. Can knowledge itself be the cause of collapse? When the system is no longer available: Adam Smith theory overriden Is the progress in knowledge of weapons leading us to war and by consequence collapse? ( a third world war) Can a lack of information be the cause of collapse? People have been making predictions about the end of the world, through out all of history based on the information available to them at the time. Why do we go gaga over numbers?

Math But experts say it's the spectacular nature of the attacks that give public mass shootings such impact beyond the affected communities, with intense media coverage lending extra piquance: five or six or even seven attacks in one year may not be statistically significant, but they're emotionally resonant.

Science Experiment

Transcript: Brainstorm What is my project about? Well, I'm interested in microorganisms like mold. Hey! I could do my experiment on mold! I know what my question is! It's: What conditions keep mold from growing on bread? Research Mold Facts The average growth time for mold is anywhere from 2 days to 2 weeks. Bread mold can be any color from orange to green. Results Well my results were that if you leave bread in the bathroom for at least 2 weeks it will grow mold The bread slices 1 & 3 in the bathroom was the only place with mold & all the other locations had no mold. I ended my experiment early because my dad accidentally threw away my Controls while he was cleaning out the fridge. Of the eight locations and three controls, two of three slices in my bathroom grew mold. I can see that I would not want to leave a loaf of bread in a bathroom or leave bread outside. I would not want an animal to eat my bread or bread growing mold. I had to end my experiment early because my controls were compromised. My hypothesis matched about half my data. My hypothesis was that mold would grow in my bathroom and my mom's car. I was a little surprised about no mold growing in my mom's car, but I guess that is just how it turned out. I did notice that in humid areas, like bathroom, mold grew. If I had additional time there may have been mold in more areas. If I tried my experimant in more places and different times during the year, I may get better, worse or the same results. If you kept bread in a freezer, it would be less likely to grow mold over a period of about three weeks to a couple months.
