Survive Biology Class - wikiHow

How to Survive Biology Class

from wikiHow - The How to Manual That You Can Edit
Scroll down for some helpful hints on getting through.

Steps

Get to know the teacher. Sometimes it works best if you have a good relationship with your teacher. I don't mean teachers pet, I mean to be at a comfortable level with the person. Remember, teachers are just like you or me. They were all in school once too, so be nice and you'll be surprised how well things will go for you.
Take careful notes (yeah, it's boring, I'll admit it), but if you write things down you'll understand it and it will be less miserable.
Make friends in the class. Time will fly by if you make some buddies in Biology!
Go on autopilot. Zone out once in a while, it can't hurt if you aren't doing anything important.

Tips

Study for tests at least a week before! 10 minutes every night goes a long way.
Prepare for labs ahead of time, it will help you greatly.
If you miss a day, make sure you catch up on the notes. This is when those friends will come in handy.

Warnings

Having a bad relationship with your teacher could result in your getting an...an...F!

How to Make a Fairly Easy Science Project

from wikiHow - The How to Manual That You Can Edit
Have you ever had trouble with school because you simply couldn't figure out what to do for your science project?

Steps

Do some research for a project. There are plenty of books and websites devoted to helping your science project be as easy as possible. They can provide you with ideas and instructions. This will help you a lot! If you're creative, make up your own idea. Ditch the overused baking soda volcano idea. Be aware, though, as this might not be the easiest thing to do because you're giving up step-by-step instructions.
Choose a project and make sure it's something you're capable of. Rocket science is not an appropriate project for a 4th-grader. Just the same, if you're in high school, the teacher will not be impressed if you do a project on nail polish.
Work with a partner if at all possible. Voilà, you both instantly split your work in half! And as the saying goes, two heads are better than one. However, be sure to pick a reliable partner. It's a pain if your partner refuses to do any work.
Start as early as possible! As with all projects, the earlier you start, the better off you'll be. If you finish a week early, you have a whole worry-free week. Imagine how difficult it would be if you had to do it all in one night.
Decorate your posterboard a little. Not every letter has to be outlined with glitter and sequins, but a little extra effort goes a long way. It's simple too! Teachers do care about appearance, and they might be willing to give a few extra credit points if your project looks nice and neat.
The night before it's due, make sure you have everything you need. It would be AWFUL if you got points knocked off because you left something at home. This should only take a minute or two. Then get a good night's sleep. That wasn't so hard, was it?

Tips

Do your best! Usually teachers know what level you're on. If you aim to go a notch higher, despite whether or not that might be better than someone else, they will most likely give you a good grade.

Warnings

Some teachers may not allow partner work.
Try not to overdo it.
If you're entering a science fair, never, ever consider cheating.

Hydroquinone (C6H6O2)

Hydroquinone (C6H6O2) is a severely toxic and very powerful chemical used in photo processing, the manufacture of rubber and is an active agent in hair dyes. Mercury in the form of Mercury Chloride and Ammoniated Mercury is carcinogenic. They appear on the list of toxic substances that can only be purchased via pharmacies with prescribed labels of toxicity.Hydroquinone or Mercury applied to the skin will react with ultra violet rays and re-oxidize, leading to more pigmentation and premature ageing. More product is then applied in an attempt to correct the darker blotchy appearance. This leads to a very vicious cycle. By inhibiting the body's natural production of melanin, your skin loses its natural protection from the sun and makes it more susceptible to skin cancer.Prolonged use of Hydroquinone will thicken collagen fibers damaging the connective tissues. The result is rough blotchy skin leaving it with a spotty darkened appearance. These dangerous products can also thin the skin, leaving it with irreversible stretch marks. A common result of skin bleaching with these dangerous ingredients is a condition called ocronosis in which the pigment drops into the dermis making it almost impossible to remove. Many have reported a blackening of the skin that looks worse than the original brown spots ever did. And sadly, once this damage has been done, it is usually irreversible. Mercury will slowly accumulate within the skin cells striping the skin of it's natural pigment leaving behind a grayish/blue pigmentation in the folds of the skin. In the long term the chemical will damage vital organs and lead to liver and kidney failure and mercury poisoning.Hydroquinone has recently been banned from various countries after studies have proven links to hydroquinone and cancer. Studies have shown that hydroquinone can be an irritant in concentrations above 4%. Some scientists have proposed that it can also lower your IQ and your verbal abilities. But despite all of this information that is known about hydroquinone, it is still widely available over the internet, so caution must be used when selecting a skin lightening product. There are many creams that actually work better than those with hydroquinone and mercury, and are natural and safe, and good for your skin. So after reading all of this alarming stuff, you're probably wondering what's safe to use to fade melasma or lighten brown spots? You should look for products containing Alpha Hydroxic Acids, Arbutin, Azelaic acid, and Vitamin C to name a few.
