Rainforest The Forest Floor Almost no plants grow in this region of 0-2% light and 100% humidity. The few flowering plants that live here tolerate deep shade. The floor itself is covered with a litter of rapidly decomposing vegetation and organisms that break down into usable nutrients. A leaf that might take one year to decompose in a temperate climate, will disappear in just six week

Real Facts On Acid Rain Acid Rain What is acid rain' Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic,

Recycling Statement is issue: This paper is about the disadvantages and advantages of recycling. Overview: As human beings, we pollute the environment through many ways. One of the major pollutants is the waste we produce. Everyday millions of tons of trash gets dumped into Earth’s landfills, but soon, those landfills will be full and we won’t have anywhere to store our waste. Theref

Respiratory System THE RESPIRATORY SYSTEM INTRODUCTION Day-in and Day-out, with out the prompt of conscious thought, the respiratory system carries out its life-sustaining activities. If the respiratory system’s responsibilities are interrupted for more than a few minutes, serious, permanent damage to tissues occurs, Followed by the break down of all the body’s systems in the huma

The Flow of Life Imagine a young girl is injured in a car accident and her mother dies instantly. The young girl is still alive but she needs to have a blood transfusion within minutes in order to save her life. The only problem is that the nearest hospital does not have enough blood reserves and the next closest hospital is too far away. This situation may sound farfetched but it co

Algea Algae are simple water plants. They contain chlorophyll and photosynthesize (retain water, light and carbon dioxide to produce food and oxygen). They are eukaryotic having a full fledged nucleus, and contrary to prokaryotic cells, they have cell walls usually composed of cellulose. Algae come in different colours, shapes and sizes (10-25 Um to 200m); some are unicellular, or found

Abortion Abortion is a morally ambiguous issue. The complexities involved are usually not represented adequately by either the pro-life or choice positions, especially in the most fervent and extreme versions of each. Pro-choice advocates use the euphemism of "a woman's right to choose" to cover the ugly fact of killing a fetus, i. e. a potential person. Pro-life adherents equate aborti

Sacred Identity Sacred Identity “Can you imagine a whole basketball team of Jordans'” says Elshtain, “what about having forty Mozarts in this world'” (Nussbaum and Sunstein 181) These are just a few concerns that come to mind when cloning is the topic. Others may feel that it is a far- fetched idea and that the government should ban cloning. However, cloning is very possible and is n

Salinity WHAT ARE THE EFFECTS OF EXCESS SALINITY ON PLANTS Salt is a mineral that is found both in solid and liquid form. The liquid is called brine. Salt contains two elements, chlorine and sodium, and is known chemically as sodium chloride. Mineralogists call salt that is found in mines halite. Salt is essential to health. Body cells must have salt in order to live and work. Sa

It is an area of frequent earthquakes caused by the plates sliding past each other. It is so called because it runs along the San Andreas Valley. The San Andreas fault was

Saturn The sixth planet in the solar system that displays its stunning array of rings makes Saturn one of the most interesting planets in the solar system. A very easy planet to pick out in the sky on account of it being one of the brightest lights in the sky, it also has a very faint greenish color that makes it stand out from the rest of the objects in the sky (“Astronomy for Kids”).

Albert Enstine strikes back Albert Einstein was born on March 14, 1879, in Ulm Germany. He lived there with his parents, Herman and Pauline. After a year in Ulm, due to the failure of his father's electrical and engineering workshop, the Einstein family moved to Munich (the capital of Bavaria), where after a year in residence there, Einstein's mother had Maja, Einstein's sister. Despite

Science Fair Project “Measuring the Brightness of an Incandescent Lightbulb” The purpose of this project was to determine the difference, if any, in 60 watt incandescent lightbulbs. All bulbs used in this experiment were ordinary, everyday lightbulbs. The experiment involved metering the amount of lumens given off by each. My hypothesis was confirmed that each bulb varied in str

Science Lab Title: What’s in the food you eat' Introduction: The source of energy required for living is supplied by the food you eat. The nutrients in food supply both the matter and the energy that your body requires for human performance. Purpose: The purpose of this lab was to determine the absence or presence of four specific nutrients, namely sugars, starches, proteins, and

Side Effects Of Abortion Abortion is the expulsion of a fetus prior to a natural birth. Many people have different views of this controversial topic. However, whether a person is for it, against it, or somewhere in between, all can agree on the result, the loss of a life. To the contrary of what some may think, abortion does not only destroy the soon to be child, it also may cause side

The Art of Teaching Science In the essay, “The Art of Teaching Science,” by Lewis Thomas, he talks about our failures in the way we teach science in our education system. Lewis believes that schools have gone about teaching science in the entirely wrong way and that they need to go about it in a totally new perspective changing the whole way we teach it in our classrooms, from a boring o

Seedless Nonvascular Plants Seedless Plants Seedless Nonvascular Plants If you were asked to name the parts of a plant, you probably would list roots, stems, leaves, and perhaps flowers. You may also know that many plants grow from seeds. But did you know that some simple plants have none of these parts' Nonvascular plants, the bryophytes, don’t have roots, stems, or leaves. They

Sleep Deprivation Before the sun is even shining through your bedroom window, the blaring radio kicks on, the time is 5:45 am, and it is time to start another school day. After an eventful day yesterday, and a late bedtime, you find it terribly hard to roll yourself out of bed. Quite disconnected, you pull your heaping covers back over your head, and within seconds, you drift back off

Sedimentary Rock Sedimentary Rocks This is a picture of a sedimentary rock. I want to talk about how this rock was formed and the erosion that took place until the rock crumbled. The first thing that I noticed from these pictures was that the rock’s location was on an ocean side. The lithification (or process of becoming a rock) of this rock seems to originate from the conglomeration

Simple Machines Simple machines can be used to make work easier and faster. Compound machines are basically simple machines placed together to work together. Work is force acting on an object that moves it a distance (W=F*d). A simple machine must have some force applied to it to do work. Simple machines let us use a small force to beat bigger forces. They can also change the direction o
