Vernier Lab Report

The liquid contained inside has no choice but to move upward and downward as the temperature creates the substances to grow or shrink. 6. Thermometers have a large bulb and a narrow tube to accentuate the change in volume. 1.

What was the reason for each one?1) Microscope-used to watch microbes. 2) Mercury indicator used to quantify barometrical weight. 3) Fahrenheit thermometer-used to show water solidifying at 32 degrees.

Approximately 12 mL of cyclohexane was put into a test tube and measured to be 9.09g. The test tube was placed in the ice bath and the temperature was measured with a thermometer in intervals of two seconds. The recording stopped once the stirring rod could not move anymore and the temperature was constant for 10

In the above hypotheses, the research done previous to the lab supported the alternate hypotheses for the colored lights in relation to the dim lights, and the null hypothesis for the experiment in which both sides of the chamber had dim light. The dim light on Side B of the chamber would be favored because, in a previous study, D. Melanogaster were exposed to different illuminations, and “their favorite resting, grooming, and feeding places were determined with an infrared-sensitive camera.” Additionally, the study used infrared beams to collect data on the activity levels of the flies during their most active period of the day under different light intensities. Each of these methods demonstrated D. Melanogaster’s preference for dim light occurring “between 5 and 10 Lux” (Rieger et al.).

In one of his elaborate missions came an idea to make a modern observatory (“Anders Celsius” Famous). Finally, in 1741, Celsius founded the Uppsala Astronomical Observatory (10). This very observatory became the birthplace of the Celsius scale in 1742

Abstract Heliox is a mixture of oxygen and helium in specific percentages, which is used in treatment of obstructive diseases (like asthma). It can be used in adults as well as in pediatrics for upper or lower airway diseases. It is almost safe and has no noticeable side effects. Introduction Heliox is a gas used in hospitals in order to help patients to breath. Heliox is composed of two gases which are helium and oxygen.

POINTS FOR and/or AGAINST these evidences (+ elaboration and support for these points) Comparative Anatomy - For: the study of similarities and differences in the anatomy of different species. This can be seen in the comparison of a human hand, cat front paw, wale fin and bat wing, they all have a very similar bone structure and bones, pointing to a common ancestor and backing up evolution.

Enron’s Obedience In 1962 a Yale psychologist Stanley Milgram performed a number of experiments investigating what he labelled “the issue of authority” he undertook the experiment to evaluate how normal everyday people were capable of doing terrible acts even when these actions went against their innate moral compass. The most notable experiment implemented was called the “Obedience Experiment”. This was a rigged experiment, test subjects would ask questions to an unseen victim, if the victim failed to answer correctly a shock would be given with the voltage increasing as the victim continued to give wrong answers, unbeknown to the test subject no shock was actually received by the victim.

The Stanley Milgram experiment video is about some people who are partaking of an experiment recreation, but have been left out of some info in order to make a successful experiment. What they did was one person was the teacher, and the other the learner, and said that this was to see the effects of punishment on learning, what they did not know was that the other person brought in the room with them was a stooge, a magician word for someone who pretends to volunteer, but actually knows everything about the act and will help rig it, so that when the teacher and learner were picked, both papers actually had teacher written on it, but the “stooge” pretended it said learner. The teacher was then taken out of the room, and was asked to ask the

The purpose of this lab was to familiarize the students with the Scientific Method. The Scientific Method is a set of rules that Scientists from all different fields use to create and develop theories. The basic steps of the Scientific Method are: to first observe and gather data, then create a critical question, next form a hypothesis, then create and conduct an experiment multiple times, next you will evaluate the results and or reject the hypotheses, finally if your hypothesis is correct you will publish your results. We used these steps to determine what the inner workings inside a particular black box. Our TA began by showing the class a particular black box.

In order to make Galileo’s thermoscope into a thermometer Santorio added a scale so that the precise temperature would be indicated by the bulb slightly below the bulbs on top. In conclusion, I believe that the first thermometer has impacted society by helping it become more efficient and useful also the Galileo thermometer would make a whole new world for new

Place the the beaker onto a hot plate that is on a low heat setting (about setting 3). Every 5 minutes for 20 minutes, measure the circumference of the balloon and record it in Data Table A. You can measure the circumference of the balloon by looping a piece of string around it then using a ruler to measure the string’s length. Record the data in the data

However, if you are checking someone’s temperature by placing the thermometer under their tongue, you are adding heat to the thermometer, which in turn heats the mercury to give you a reading to determine whether or not they have a fever. This is also true when you run a thermometer under hot water from a faucet. Helium is a gas that is used in balloons. As long as you keep the temperature constant or continue to add heat, such as a very hot room, the helium will continue to expand and the balloon will stay inflated.

Introduction The practicum has been developed in RIKEN Centre of Developmental Biology in Kobe, in the laboratory of Axial Pattern Dynamics under the supervision of Inomata-sensei and Matsukawa-san. In the laboratory they try to artificially regulate the gradient shape, they can control morphogen-dependent pattern formation. In general, the shape of a gradient is defined by three factors; synthesis, diffusion, and degradation of morphogen.
