Turbidity, the dark coloration and other matters prevent the penetration of light deep into the water. As such, the growth of submerged vegetation happens in the shallow regions of the river. The river is fed from tributaries some of which are salty, the Atlantic ocean, tributaries and human wastes from industries and treatment plants for waste water. The lab report presents ...

Lab 2: What I liked

I liked the fact that the abstract was straightforward and direct. As soon as I read the first sentence, I knew what this lab was about and what the experimenter was trying to measure.
I also liked that the experimenter was honest in that he or she is uncertain of the values that were calculated or the way that the experiment was performed. Rather than reporting false values to make the lab report look better, the experimenter acknowledged that the outcome of the lab was not optimal. That is ultimately more useful for the people trying to learn by ...

In 1956, Warner Brothers released a cartoon called “Bugs’ Bonnets.” At the start, the narrator shows the ways in which the things a person wears influence their behavior. A mild-mannered man in a business suit suddenly is put into pirate garb, and he starts shouting and bellowing like Redbeard himself. The narrator then moves to a change in hats; at that point, a truck driving down the road labeled “Acme Theatrical Hat Co.” has its back doors open, and the hats start floating down into the value. Bugs Bunny and Elmer Fudd just happen to be running around in ...

Introduction

Accurate and precise measurements are of uttermost importance to chemists everywhere. A measurement is said to be accurate when it is very close to the accepted value. A precise measurement is one in which repeated measures yields values or figures that are very close to one another. However, not all measuring instruments have an equal ability to give accurate and precise measurements. In any given experiment, the techniques and the equipment used to collect data should essentially be of the same precision. In the course of an experiment, there are bound to be less precise measurements and it these ...
