We Are Young But We Can Make a Difference in Our Community | National Youth Leadership Council. Last year in 9th grade, my government class was assigned a service-learning project. We were told to research a topic we were interested in and volunteer with a related organization. Sarah, my project partner, and I chose to focus on honey bees. We knew there was a problem with the decrease in the population, but after we did some research, we found that it was much more serious than we ever imagined.
As we dove more into the issue we learned some amazing statistics: honey bees can travel up to 55,000 miles in a lifetime; one worker bee can visit over 2,000 flowers a day; and bees pollinate over 70% of our food. These facts are wonderful; however we didn’t always read such happy things. Some other stats we found talked about how in just 50 years, America has lost over 2.3 million honey bee colonies. Sarah and I started our research in April, and by mid May we had fallen in love with bees. Throughout these last couple of months, Sarah and I have learned all about bees.

50 Awesome Chemistry Videos For The Busy Science Teacher. Though we don’t often recognize it, chemistry defines nearly every element of our everyday lives. From the reactions that fuel the sun to the biology of our bodies to the technology in our gadgets, chemistry is at the heart of everything we do and is the central science that unites biology, physics, geology, astronomy, medicine, and countless other fields. Yet chemistry doesn’t always get the credit and recognition it deserves for playing such an awesome role in, well, everything. If you’ve been slighting chemistry, there’s no better time to give the field the credit it deserves than National Chemistry Week.
Founded in 1987, the week-long event has helped bring awareness to the role chemistry plays both in our lives today and in our future. You can get in the spirit of the event by checking out a few (or all) of these amazing chemistry videos online. Some are funny, some impressive, but all will showcase the true awesomeness of chemistry. Amazing Reactions and Experiments Lectures Courses. George Whitesides | Speaker. In his legendary career in chemistry, George Whitesides has been a pioneer in microfabrication and nanoscale self-assembly. Now, he's fabbing a diagnostic lab on a chip. Why you should listen Someday Harvard chemistry professor George Whitesides will take the time to look back on the 950 scientific articles he's coauthored, the dozen companies he's co-founded or the 50-plus patents on which he's named. (He works in four main areas: biochemistry, materials science, catalysis and physical organic chemistry.)
Among his solutions is a low-cost "lab-on-a-chip," made of paper and carpet tape. What others say “Most of the world is self-assembly. Ramsey Musallam | Speaker. Helen Fisher: The brain in love. Helen Fisher | Speaker. Anthropologist Helen Fisher studies gender differences and the evolution of human emotions. She's best known as an expert on romantic love, and her beautifully penned books — including Anatomy of Love and Why We Love — lay bare the mysteries of our most treasured emotion. Why you should listen Helen Fisher's courageous investigations of romantic love -- its evolution, its biochemical foundations and its vital importance to human society -- are informing and transforming the way we understand ourselves.
Fisher describes love as a universal human drive (stronger than the sex drive; stronger than thirst or hunger; stronger perhaps than the will to live), and her many areas of inquiry shed light on timeless human mysteries, like why we choose one partner over another. What others say “In hands as skilled and sensitive as Fisher's, scientific analysis of love only adds to its magic.” — Scientific American.

You know, that kind of thirst that makes it hard to swallow and your mouth feels all cotton-ball dry. I turned on my kitchen faucet and gulped down two big glasses of water before continuing with my morning routine: I washed my face, brushed my teeth, and took a shower. I then filled my water bottle, watered my plants, and made coffee. I used water to do all of those things. I often take for granted such easy access to clean, safe, drinking water and forget what a pivotal role it plays in our day-to-day lives.
Today, on World Water Day, we recognize that one’s access to clean water should not depend on where they live in the world; it is a basic human right. According to water.org, 884 million people lack access to clean water around the world – that’s almost three times the population of the United States.

Biodiversity-in-costa-rica | about-us.
Biodiversity is a resource with enormous potential, both for intellectual and economic purposes and as an instrument for a country’s development. The tropical zones of the American continent (Neotropics), where Costa Rica is located, contain a greater diversity of species and ecosystems, as well as a broader range of interactions, compared with other tropical regions of the world. Obviously, this diversity is also much greater than that of temperate and cold regions. With a land area of only 51.100 km2 (0.03% of the planet’s surface) and 589.000 km2 of territorial waters, Costa Rica is considered to be one of the 20 countries with greatest biodiversity in the world.
Its geographic position, two coasts and its mountainous system, provides numerous and varied microclimates, representing some of the reasons that explain this natural wealth, both in terms of species and ecosystems. Costa Rica has a very comprehensive legal framework for the conservation and sustainable use of biodiversity. Conservancy Magazine - Forever Costa Rica. For being one of the most biologically rich spots in the world. Though it occupies less than 0.01 percent of the planet’s landmass, the tiny nation is home to 5 percent of all species.
And the country has pursued an aggressive agenda to protect this diversity. The government has set aside 26 percent of its land for conservation, which means it is closing in on an important milestone under its treaty obligations in the 1993 U.N. Convention on Biological Diversity. But to be the first developing country in the world to meet its commitments to protect biodiversity, Costa Rica still has work to do. One priority is adequate funding for its parks. Even in a relatively prosperous developing country like Costa Rica, support for conservation programs and park rangers has often proved ephemeral. Another concern is the oceans. The country’s ocean diversity—an estimated 3.5 percent of all marine species live in its waters—is as fantastic as the diversity of its lands.

By: Stephanie Pappas, LiveScience Senior Writer Published: 09/20/2012 12:22 PM EDT on LiveScience A part of the brain usually associated with movement may also control our responses to rewards, according to new research that finds stimulation of the region with an opium-like chemical can make rats gorge on M&M candies.
The brain naturally produces opioids, or chemicals with similarities to the drug. One of these, enkephalin, induced hungry rats to pounce on chocolate treats faster the more of the chemical they produced, researchers report online today (Sept. 20) in the journal Current Biology. When scientists dosed the rats with a big jolt of enkephalin in a brain region called the neostriatum, the rats became eating machines, downing the equivalent of a 150-pound (68 kilogram) person eating 7 to 8 pounds (3.1 to 3.5 kg) of M&Ms in an hour, said study researcher Alexandra DiFeliceantonio. Triggering gluttony The roots of motivation. Magazine: Chocolate: page 8.
Page Eight Phenylethylamine is also found in chocolate. It's related to amphetamines, which are strong stimulants. All of these stimulants increase the activity of neurotransmitters (brain chemicals) in parts of the brain that control our ability to pay attention and stay alert. While stimulants contribute to a temporary sense of well-being, there are other chemicals and other theories as to why chocolate makes us feel good.
How does this work? THC, however, is not found in chocolate. Still, the research results made for great newspaper headlines. Anandamide, like other neurotransmitters, is broken down quickly after it's produced. More research needs to be done to understand the effects of chocolate on the brain, and Piomelli's group is currently working on a new study that should be published next year. . © Exploratorium. Why Your Brain Loves Chocolate. As mid-February rolls around, two subjects, hand in hand, start winding their way into our societal consciousness. Like it or not, you probably have two items “on the brain” these days: love and chocolate. Now, I sincerely hope you have an affinity for love.
Likewise, probability indicates that you most likely have an affinity for chocolate. But what is it about chocolate that has all of us running to the store on Valentine’s Day to procure those shiny red boxes for our loved ones? Consider the sensations that love creates in the brain. When we are in love, what do we feel? What are the elemental feelings and emotions that a true, heart-felt loving relationship create? Now, consider chocolate. Imagine that you have just received that delightful box from your loved one. As you chew, savor and swallow, your body begins to digest and metabolize those 300+ compounds. If you were in a courtship situation, wouldn’t you take actions to engender these same sensations in your prospective mate? CNN Food: Come on, get happy... with chocolate's help. Chocolate and the Brain" Chocolate has all of the ingredients needed to make it a wonder drug.
After all, it contains compounds similar to those found in ecstasy, morphine and marijuana. By all rights, eating a bar of chocolate should send you into orbit. So, why isn't this stuff regulated by the FDA? Why aren't chocolate bars sold from locked cabinets behind the pharmacy counter? As a result of the energy drinks, coffee, cigarettes and, yes, chocolate humans consume these days, our brains have become quite accustomed to the effects of drugs that release pleasure-inducing chemicals. This process is how chocolate (or any other substance, for that matter) gets its eater high. Still, there are pharmacological compounds that produce feelings of pleasure and stimulation in human beings. Global Classroom and chemistry. Homemade Bug Spray for Gardens - Homemade Bug Spray. Since Spring finally decided to stop being on vacation and show up this year many are finally being able to plant those beautiful and yummy gardens!
The only problem is that with this beautiful weather also comes another visitor-little buggies. These of course can be the most annoying and destructive aspect of planting a garden. If you're a first time gardener-they may push you over the edge a bit! Trying to figure out what to spray on your garden to get rid of these pests can also be such a pain. Many, if not most, pesticides on the market today are filled with such harmful chemicals-it would completely defeat the purpose of planting your own garden! If you want tons of nasties on your food, you can hike yourself to the nearest big box store to pick them up.
I hope to have a bigger garden someday soon, but because of our HOA we are not allowed to have very much.

Organic Agriculture: What are the environmental benefits of organic agriculture? Sustainability over the long term. Many changes observed in the environment are long term, occurring slowly over time. Organic agriculture considers the medium- and long-term effect of agricultural interventions on the agro-ecosystem.
It aims to produce food while establishing an ecological balance to prevent soil fertility or pest problems. Organic agriculture takes a proactive approach as opposed to treating problems after they emerge.Soil. Soil building practices such as crop rotations, inter-cropping, symbiotic associations, cover crops, organic fertilizers and minimum tillage are central to organic practices. These encourage soil fauna and flora, improving soil formation and structure and creating more stable systems. In turn, nutrient and energy cycling is increased and the retentive abilities of the soil for nutrients and water are enhanced, compensating for the non-use of mineral fertilizers.

For as long as people have been working around the clock and undergraduate students have needed a little boost to get through a day’s lectures, coffee has been the go-to product. Coffee, and the caffeine that we extract from it, powers our 24-hours-a-day society. But while many students and professors worship coffee, a tasty cup of java contains plenty of chemistry as well. Coffee relies on its chemistry from the moment the bean is picked to the first sip. Moreover, coffee’s most famous component, caffeine, plays a powerful role, even outside of that first cup of joe.
Coffee: A Brief History If coffee could tell a story, it would talk about where it grew up, how it lived, and how people have consumed it over the years. Preparing the Beans After being picked, the ripe coffee “cherries” sink and become pulped to extract the beans. Once the beans have been extracted, they need to be roasted.
