The Gratitude Experiment is a movie by Douglas Vermeeren who created the law of attraction film The Opus. The Gratitude experiement now has a website up www.gratitude-experiment.com where you can see the trailer. There is not much else that is known about the movie at this point, except that it is creating a stir among religious groups who feel the movie will take a very scientific approach to possibly explain away their belief in God and replace it with a new-agey conversation about how all things are the result of calculated science. This argument is somewhat unfounded as no one has ever said what the film will teach or portray.

His last film did express a few comments that would lead one to belief that Vermeeren does belief in God, but at the same time one of the spekaers within the film, Jack canfield shared a very evolutionist view of the creation of the universe.

There is no news yet on who Vermeeren has chosen as participants in this latest film. perhaps that will be more of an indicator of what we can expect.

Alcian Blue staining is used in histology to selectively stain acidic polysaccharides, such as mucins and glycosaminoglycans, in tissues. It is particularly useful in diagnosing diseases characterized by abnormal mucin production, such as mucinous tumors. Alcian Blue staining can help pathologists identify these substances and aid in accurate diagnosis.

Water power is used to produce electricity - all homes schools and businesses use electricity so hydro power is just part of this.

If you mean direct water power using your own water wheel to drive some mechanism, this is rather old fashioned. Millers used to do this, but surely no-one still does this? I don't see any relevance to homes and schools, what would they do with a mechanical water wheel?

Check out sciencebuddies.com they have some great projects!

Some tools that are used in science include microscopes, tweezers, telescopes, computers, maps, and Petri dishes. Other tools include magnifying glasses, chemicals, and even Bunsen burners.

water freezes at 0o celsius, so at -15oC it would be solid

there will be health concerns :(

Role of Science in production process:- Industry science has always played a crucial and important role in production.The history of human kind,is principally the history of how human beings have attempted to control and transform nature for their own use.In this, difft tools and means of production have played a crucial role.In the last few centuries,the means of production have become very complex and we can refer to the Industrial age,Atomic age or Space age etc on a very difft basis.Early man strived to extract,fashion materials so that they could be used as tools to satisfy his prime needs,techniques were discovered. Social classes came into conflict in this process and create new social organisations.In Europe at a certain stage of development,the big land lords who jealously guarded their territories,and the merchants and tradesman,as also common laws for large geographical areas,came into conflict .A few centuries ago,science and industry developed together so that the growth of science and the improvement in the methods of production were intimately related.In the present stage science has grown to such a point that it leads to the development of industry.

Safety is PARAMOUNT

The following steps would aid in the design of a good experiment:

* Identify what you want to investigate (e.g. Does it hurt to touch a hot iron) * Consider what should be in the experiment (e.g. Irons, steam irons, travel irons, hands) * Set criteria (what is hot, what are people, what is touch, how long does a touch last)

* Consider how to eliminate variables (e.g. Broken irons, irons turned off, people with cooking gloves, people with artificial arms, people with peripheral neuropathy etc.) * Determine how many trials and how many subjects and how much equipment (irons, thermometers, watches, band aids) is required * Determine if there is a need for blanks (iron is cold or off, people touch other objects, etc. to eliminate people just playing along)

* Get test subjects and test equipment together and do experiment

* Repeat experimental procedure gathering data and recording results * Graph or process data (e.g. iron temperature vs. ouches by contact time) * Draw conclusions and write report (The data may show that hot irons do or don't hurt, but you don't know until the experiment is done). * Ask for someone else to review your procedures, experiment, results and conclusions (peer review) to determine if you've missed something * Publish report.

There math tools used in a experiment (Ex: Like in a hypothesis) If u use them u will be able to measure your results and have accurate data.

Vaccine is made by growing germs then purifying them for injection. "Egg based technology" means they grow them in eggs.

The type of balances that measure mass is usually the triple beam balance, you move the weights around units almost like the s just the right amount. {its almost like the measuring scales that doctors use to measure your weight, but tinyer!}

doctors and researchers have recently found stemcells

True. A balance IS used to measure the volume of things.

A control group is the unaffected group in a science experiment.
