What constitutes laboratory science in high school?
I’m looking at colleges and the different requirements. There is one college that requires 3 science credits and all 3 have to be laboratory science. So far I have earth science and biology and I’m taking marine biology next year. I’m a rising senior and I need to know if I have what I need to qualify.
Earth science is not usually considered laboratory science. You should take chemistry or physics to make sure you have all the lab Science courses you need. Usually colleges want biology, chemistry and physics.

Science of Astronomy – Information About Astronomy for Kids on the Internet!
The science of Astronomy is interesting and varied. There are a lot of resources for it for kids who are interested in the planets, the solar system, the universe and everything else that’s part of this exciting Science. For children, many parts of it are magical and thus they are drawn towards the moon, the stars and far distant galaxies.
The moon is Earth’s only satellite. It takes about 27 days to orbit the Earth. Being so near, it has hosted the only human footsteps on a space object other than the Earth. Gravity between the moon and Earth causes the tides. It’s brightness in the night sky attracts many children to learn more about it.
Then there’s our sun. Earth is quite far from the sun. The distance fluctuates between about 91 million miles and about 94 million miles. That’s because Earth’s orbit around the sun isn’t a circle, it’s an ellipse. If there were no sun, we wouldn’t be alive. Our light and heat comes from the sun. Over 98% of the total stuff in our solar system is in the sun. Think about how small a person is compared to that. So play is a wonderful time to be introducing science to them. Think of the games that we used to play; Don’t Spill the Beans, for more details visit to www.profit-pulling-niches.com Don’t Break the Ice, the Telephone Game, Lincoln logs, patty cake, each of these games has a science behind it. Each of these games are wonderful science games or toys for the pre K school age group.
We live in the Milky Way Galaxy. It’s full of space stuff. Even with all this stuff to fill it, it’s mostly empty. At over 100,000 light years wide and 3,000 light years high, for more details visit to www.auto-cons.com that means the galaxy contains a whole lot of nothing. The center of our galaxy is about 30,000 light years from Earth. Even with all that space there are about 100 billion stars in the Milky Way. In fact the galaxy was named for the thick group of stars in the main portion of it. People thought it looked like a stream of milk, so called it the Milky Way. There are four types of galaxies – elliptical, lenticular, irregular and like the Milky Way, spiral.
There is a lot of information about astronomy for kids on the Internet. Kids could spend hours wrapped in detailed 3D representations of the universe around us.

What science careers incorporate knowledge of foreign languages?
I’m looking at colleges and wondering what to major in. I’m very interested in science (specifically biology, genetics, chemistry, and astronomy, but science in general as well), and I’ve been studying Spanish and French. I’d like to pursue these topics in college, but I’m not sure what practicality they’ll have together in terms of future jobs. Are there any science Careers that require or can benefit from a knowledge of multiple languages, and if so, which are they?
Pharmaceutical sales representative.
Biologist, especially if you work for government or non-profit.
Almost any doctor, our world is becoming multilingual.
Traveling Geologist, for instance, lets say you visit the middle east to dig up some dinosaur bones.
Chemist, if you work in the chemical engineering field you may have to take some trips to china, japan, russia, europe, etc.

Science Fair Project On Testing Drinking Water
You are intelligent enough to know that the purpose of most science fair projects is to teach students how to use scientific methods to solve problems on their own. A science fair project can allow students, parents, and teachers to make new discoveries together. One of those discoveries might be how clean your drinking water is.
Students may expect faucet water to be clean, but is it? A science fair project on testing drinking water can help them learn what is in the water they use. This outline will help them and you conduct a drinking water test.
State Your Hypothesis
A good example might be, “If I test drinking water from different sources, which will I find to be the best for my Health?” A poor example would be, “If I drink tap water, what happens?”
Background Research
Learn all that you can about what water may contain. Research the effects of various contaminants, minerals, etc.
Develop a Drinking Water Test
What kind of drinking water test will you use? What kinds of drinking water will you test? Will you buy a kit, or simply order appropriate test materials? How will you collect the water to be sure you do not change its content?
What You Need for Drinking Water Tests
Students will need Colorimetric test strips for many drinking water tests. Kits are available from science fair websites. Water Safe Drinking Water Test is an EPA standardized, laboratory certified simple kit that identifies harmful levels of 8 different common contaminants in water: bacteria, chlorine, lead, nitrates, nitrites, pesticides, pH, and water hardness.
Predict Results
Write out a prediction of what you expect. Will your city tap water be the best water for your health? Should your family pay money to drink only bottled water? What do you predict your drinking water test will reveal?
Conduct Your Drinking Water Test
Students may choose from many drinking water tests. Here are a few possible tests. Younger students may want to use only one. Older students may combine a series of drinking water tests.
1. Basic: A basic drinking water test might allow students to test water for alkalinity, chlorine (both free and total), nitrate and nitrite, pH, and water hardness. What is the basic make-up of your water?
2. Bacteria: Along with a basic drinking water test, you might test for bacteria in the water. Water from a drinking fountain may show bacteria that collect on the bubbler and wash into the water.
3. City Water: What is in municipal drinking water? You can use the basic drinking water tests above, but check, too, for metals and sediment. Are corroding pipes contaminating the water?
4. Well Water: Since the government does not test private wells, there may be contaminants in the water taken from them. What might you find? Would you expect more sediment or less? Would your drinking water test be likely to find pesticides if the well is near a farm or garden where they are used?
5. Bottled Water: Is bottled water really pure? Is it better than tap water or worse? Run a drinking water test on it and see what you find.
6. Water Cooler: If your water cooler is typical, a large five-gallon bottle is turned upside down into the drinking water crock. Might there be germs on the bottle top? Will a drinking water test show up these germs?
7. Pet Water Bowl: Pet drinking water tests will show you what your pet’s water contains. The pet bowl should not be cleaned right before the test. Allowing your pet to drink from it will show whether or not the water is still pure enough for humans.
Repeat Your Drinking Water Test
A good scientist repeats tests to be sure the results are the same. You will not have accurate results if you run your drinking water test only once.
Analyze
Analyze the results of your tests. Which water is purer? Which one tastes better, looks better, and smells better? From your analysis, do you think your prediction will hold up?
Arrive at Conclusions
Draw conclusions from your drinking water test. Look at all the evidence and decide what it means in regard to healthy drinking water.
1. Which water contains the fewest contaminants?
2. Which water contains the fewest bacteria?
3. Which water is best for your health?
Prepare Your Display
Decide early how the display will look and leave plenty of time to complete it. Will you have photographs? Will you have clear glasses containing water samples? How will you display used test strips?
Most science fair projects require a display board to communicate your work to others. A three-panel display board that is 36″ tall by 48″ wide when unfolded is standard. On your board, include these elements.
1. Title: Make it catchy – and big enough to read from across a room.
2. Hypothesis and research: Organize your information from top to bottom, left to right, as though you were planning a newspaper page. Put Hypothesis and research information on the left side of your board.
3. Materials and procedures: Place this information just under your title in the middle of the board.
4. Data / Charts / Photos: These go at the bottom of the center part of your board.
5. Results and conclusions: The right side of your board holds the final information about your drinking water test.
A science fair project on testing drinking water can be interesting and exciting, appropriate for any age student. The results may surprise everyone.

Do You Like Science Fiction?
Many folks enjoy Science Fiction and recently a friend who is a vegetarian and has lived all over Europe expressed to me his years of reading Sci Fi and listed many of his favorite authors. These included authors like Robert Heinlein, Charles Sheckley, Larry Niven, Isaac Asimov, Ursula k. Leguin… older science fiction for the most part also a little of say William Gibson or newer Heinlein.
In fact he likes science fiction so much he is considering on writing his own Science fiction book soon. I thought to myself; “wow!” that is one heck of a line-up of great authors so indeed, I bet whatever he writes will be inspired by some of the greatest science fiction writers of all time. Myself I like Arthur C. Clarke, Isaac Asimov, Ben Bova, Caleb Carr, Stephen Baxter, Jules Vern, Gene Roddenberry, HG Wells, and try to stay away from the Science Fiction Fantasy. Although, I must say I do rather enjoy such movies in the theatre. Since then space search has been a constant battle between the two countries with the astronauts of the USA and cosmonauts of Russia striving to explore more, to find more and to know more about space. In this conventional viewpoint, the wave, “wavicle”, for more details visit to www.auto-cons.com or particle separates from the source, moves through empty space, and then is absorbed by the sink, thereby becoming a part of the sink and fully divorced from the source. That way perhaps you won’t notice being pelted by friendly fire from casually discarded space junk, nor will you be aware of your vital organs expanding and bursting in the vacuum created by zero air pressure
Between the two of us, I’d say that those are very famous and interesting authors. So we discussed the future of propulsion Technologies that we both believe to be forthcoming and decided we wouldn’t mind a long-term space mission for the benefit of exploration, truth, science and humanity. Energetic radiation/absorption along primary (oscillation along the line over time; can be modeled as a pair of points on the line, one on each side of the center, for more details visit to www.profit-pulling-niches.com moving with equivalent but varying spacing between each of them and the center point. “Yes, I too would have no problem with a year’s space flight, each way or even 5-years, if I had access to information to learn and study.” I told him.
In the future Virtual Reality might help entertain space travelers from going stir crazy? Soon mankind will depart from this Home planet in search of our future destiny and all that awaits. Amazingly, enough it won’t be long now.

How do i get good marks in science even when i hate it?
I hate science. My primary and secondary school teachers have never made me interested in it. It is always confusing and they always deduct so many marks for using a wrong word and u have to explain every detail even for a one mark question. U also need to aply wht u learn and i am bad at that. I always get low marks for science. There is sooooo much memorising to do!!! I hate it yet i want to do well in it. Many pple say tht math and science are related. I love math but hate science. How can it be so? I normally get A+ for math. Any science teachers or excellent Science students can help me?
find some interesting facts in science and find thing like experiments to make you interest in it….. i used to hate it before.. it just takes the will to have interest in it.. and if you don’t understand you can ask the teacher to make it all easier for you
Kids Do Science
Children, being curious by nature, are always fascinated by Science. In order to keep kids interested, there are several scientific methods you can expose them with.
Children wonder about lots of things. They are naturally curious. In one of the programs at the Savannah River Ecology Laboratory, they see the various levels of children’s curiosity. Generally, kids want to know the answer on some questions like:
-How big is a polar bear?
-How deep is the ocean?
-If whale and shark will engage in fighting, which will win?
Although these questions have been answered many years ago, we also want to do better and teach kids to answer these questions themselves. We can do this through the wonders of Science.
Science must not be complicated, especially for children in the elementary level. In certain activities, we need to emphasize that science is a process. It is fairly straightforward. We can even define Science according to Richard Feynman, “a special method of discovering things as very tough but really simple”.
In fact, there are variations in the so called “Scientific Method”. Scientists do things in different ways. This includes:
-emphasize experimental tests
-observe
-studies complex mathematical models
Although they differ in some aspects, they still follow the fundamental steps in the scientific process. Those integral steps are:
observing, wondering
hypothesizing or predicting
experimenting
analyzing
concluding
All the activities used in teaching students how to do science follows the components of the Scientific Method. This would be:
observation of nature
Wondering Why?
Forming hypotheses in an “If” format
Collecting data that includes defining dependent vs. independent variables. By using appropriate experimental controls and repeated trials.
Analyzing data
Deriving to conclusions
Asking the next questions
Using the scientific method in a variety of activities will help teachers and students find it enjoyable. It is also a useful method to learn about nature and how things work.
Here are suggested workshops that use “comparing and classifying”. Students will work in groups of four for this type of ands-on experiment. It focuses on:
-planets
-atmospheres
-soils and
-classifications of objects
TERMINOLOGY
Process related
observation
hypothesis
comparison
classification
prediction
dependent variable
independent variable
inference
data

ACTIVITY OUTLINE:
-The first 50 minutes of the workshop consists of the following:
Slides
Demonstrations about object classification
A discussion on the search of life on Mars, which will be conducted using fossil evidence of Martian meteorites.
Students will work in groups of four to examine soil components like:
-sands
-clay
-pebbles
-organic matter
Each student will examine three vials of soil particles.
They will use their senses in order to record data on certain particles.
-size
-texture
-smell
-color
The group will combine their samples and decide how they will classify this soil. This will be based on various soil characteristics.
Ex. Students will be assigned occupations like:
-farmer
-builder
-artist
They will then decide on how to categorize the soils. This is in accordance with which properties would be most important to people, especially those with different occupations.
Thus, as you go along, children will realize what it means to do science. Kids will realize that doing science is to learn its methods. Learning its methods means they need to:
-observe
-question
-hypothesize
-gather data
-analyze data and
-conclude

Science Fiction Movies
In recent years, science fiction movies have made a big comeback in Hollywood and I, for one, consider that a very good thing.
I like to be surprised when I go to the movies. I like to see things that I’ve never seen before and I like to be confronted by virtual realities that I did not even think possible. That’s why science fiction movies are my cup of tea.
They traditionally cover a wide range of subjects and themes, including several that are uniquely their own. Today’s trend in science fiction puts a premium on special effects, backed by today’s cutting-edge technology that can make even the most bizarre scenes seem realistic, such as alien life forms, spectacular battles in outer space, time Travel or traveling to other worlds at the speed of light.
Often, science fiction films are purely speculative in nature and are peppered with recurring themes involving Science and technology. Other prevalent themes in sci-fi movies are mysticism, magic, the occult and the supernatural, which are also key elements of fantasy or occult/religious movies. In fact, quite a number of films blur the line between these genre, such as Forbidden Planet, Chronicles of Riddick, and the Star Wars series.
It’s hard to define precisely what makes a science fiction film because the genre has no universally accepted definition. In fact, science fiction may vary from viewer to viewer in that what is sci-fi to me may be fantasy or horror to you.
If you’ve been a long-time fan of Hollywood, then you know that science fiction has come a long way. There was a time when special effects meant putting a toy spaceship at the end of a string and waving it in front of a camera or having someone dress up as an orangutan and terrorizing an entire city. Certainly, the special effects in science fiction movies have evolved from the downright laughable to today’s breath-taking and awe-inspiring treatments that seem truly realistic. Some of the great milestones in this regard are marked by films such as 2001: A Space Odyssey, the Star Wars films, Star Trek: The Motion Picture and The Matrix.
Of course, science fiction films just seem to be getting better by the year, as evidenced by such recent hits as “Lord of the Rings”, “I, Robot” and “Superman Returns.”

How did Science play a role during the Renaissance and why was science another means to disobey the church?
How did Science play a role during the Renaissance and why was Science another means to disobey the church? Why was it taking a risk to be a scientist during the Renaissance?
-Protestant Reformation-
i need help so that i can study for my final which is coming up in less than a week!!
-Scientific Revolution-***
For the Renaissance, the truth of nature can only be obtained through experience and observation guided by the use of reason … this went against the tenets of the Catholic church, who were no longer accepted by the Renaissance, which not ceased to be Christians, but do not accept anything that could not be proven through experience and observation (with the exception of faith in God, of course) …
-It was the Renaissance that Europe has abandoned the complicated Roman and began using the simple and practical figures brought out by the Arabs (so named after Arabic) … that greatly facilitated the calculations … men and women Renaissance realized that mathematics helped enough to understand and master the world …
the Renaissance, the science has known great progress:
- The Italian Cardano created in 1543 to negative numbers, ie less than zero …- 1, -2, -3, etc …
- The dutch Stevin showed that the fractions podeiam be written with decimal numbers, facilitating the calculation … that is, 0.25 is equal to 1 / 4 …
- Physics was the great great works of Copernicus and Galileo on the Geocentric model, which caused a serious confrontation with the Catholic Church, which almost leads Galileo to the fire of the Inquisition …
- The mechanical clock was invented in the fourteenth century … the thermometer in 1592 and the microscope in 1590 …
- In shipping, the Portuguese were pioneers … they perfected the astrolabe and the compass and created a small and agile caravel …
- The German Gutenberg invents the typographer in 1454, making the books much cheaper and facilitating the dissemination of knowledge …
