WHAT DOES SI MEAN IN SCIENCE? HELP PLEASE!!!!
yeah SI units?

Standard units. (literally Le Système International d’Unités)

That means distance should be measured in meters, not km or miles.

time should be measured in seconds, not hours or days.

ect…

In theory every value can be expressed as one of 7 base SI units (meters, kilograms, seconds, amps, kelvin, moles, candela) but we make life easier for ourselves by having derived SI units

For example the SI unit of catalytic activity is the Katal which is just moles per second, but easier to remember.

Just google what it is your trying to find the SI unit for and it’ll tell you.

I am home schooled . How can I enter a science fair ????

In our area there is a home school group that enters its members. They act as a private school. Check with the local home school groups in your area for science fairs, spelling bees, field trips, museum classes, co-ops, park days, teen activities, PE and team sports, and lots of other activities. You may need to check several different groups to find the one that caters to your needs best. Good luck and have fun.

science….?

Posted on October 16, 2009 By admin in Uncategorized

1. What is the purpose of a control test?
2. Why is reproducibility such a vital component of science?
3. Does theory become stronger or weaker the more it is modified to account for experimental evidence?
4. What kinds of questions is science unable to answer?

The control test is necessary to rule out any effects on the results that might have occurred because of the environment or suggestibility.
A placebo pill(sugar, fake) is used in medical experiments to rule out any effect of just giving a pill might have had.

An experiment must be able to be reproduced to prove that it was eal and not faked.
Theory becomes stronger the more experiments give it proof. If more is discovered about the environmental effects then that all is needed to be accounted for.
Science is not able to answer questions about God in so many words, but just the immense world and its contents are proof of a God .

Some technology and processes that are likely to impact on the horse industry workplace?

What are some technology and processes that are likely to impact on the horse industry workplace?

Need the answer as soon as possoble thanks!
Sarah.

Right now, the industry seems to be focused on different racetrack surfaces besides traditional turf and dirt.

This has caused a great deal of controversy among horsemen, and the jury is still out as to if surfaces such as

•Polytrack
•Cushion Track
•Tapeta Footings
•Equitrack

Are indeed safer for horses or not, some folks believe they are but on the other hand some horsemen continue to prefer a traditional dirt surface.

http://en.wikipedia.org/wiki/Synthetic_racetrack_surfaces_for_horse_racing

Other than surfaces, betting technology has been a bit different than in the past. Years ago, one could only wager on their own local track and through a human teller. Now there are self betting machines, simulcasting from tracks around the country and the world, internet wagering, simulcast outlets and casinos like in Vegas or Atlantic City that have wagering rooms.

Also, many racetracks are lowering the minimum bet. For many years, the minimum was always $2. However, in most pools in New York you can wager $1 to win also many racetracks now have a ten cent superfecta, and Retama Park in Texas offers ten cent trifecta wagering as well. These lower base bets are viewed as more appealing and advantageous to most professional players because they can beat the witholding tax on big wins by purchasing multiple .10 tickets as opposed to one $1 or $2 base ticket.

Has science figured out how the human brain stores and retrieves information?

Posted on October 11, 2009 By admin in Uncategorized

If the human brain is a biological computer, has science figured out how to manipulate (store/remember, access/recall, inject/think) the information of the brain.
By saying the human brain is a biological computer, I meant that it uses electricity the same way that a PC does.

Science has learned a lot (but not nearly all) about how the brain works. The hippocampus is a key player in the memory game. Calling the brain a biological computer is simply an analogy.
