Teaching the Scientific Method How to introduce students to the scientific method Students, and sometimes even teachers, often think scientists only use the scientific method to answer science-related questions. In fact, you can apply the scientific method to almost any problem. The key is to use the elements (steps) to reduce bias and help come to a solution to the problem. The scientific method is the standard in the laboratory, but don’t be fooled by the name. It is also used beyond the laboratory to solve everyday mysteries and problems.

The next installment in our mini-film fest proves otherwise, offering a close-up look at some medicinal chemists who are busy carrying out their research in warm waters off the Florida Keys. This aquatic adventure may not be as action-packed as “Pirates of the Caribbean” or “Finding Nemo.” But these researchers from the University of Florida College of Pharmacy in Gainesville are out to discover something far more valuable to patients than sunken treasure: marine life with chemical compounds that may provide the basis for new treatments and cures. Here’s their quick summary of their work: “University of Florida College of Pharmacy Researcher and Center for Natural Products, Drug Discovery, and Development Director Hendrik Luesch, Ph.D., collects and studies marine organisms from oceans in Florida and around the globe that have potential for development into drug therapies and disease prevention.”

The One Swedish Mine That Gave us Seven Chemical Elements One of the most unheralded sites of scientific discovery in history is a rock quarry on the outskirts of the small Swedish village Ytterby. The site opened in the 1700s to feed European porcelain fads, but soon reports began to circulate of strange materials coming forth from the Earth. The mine ended up being the site of discovery of seven new elements, four of which are named after the town. Tom Scott went to visit it.

The Diversity of Coolia spp. (Dinophyceae Ostreopsidaceae) in the Central Great Barrier Reef Region Background Dinoflagellates are important primary producers, crucial in marine food webs. Toxic strains, however, are the main causative agents of non-bacterial seafood poisoning, a major concern for public health worldwide. Despite their importance, taxonomic uncertainty within many genera of dinoflagellates is still high. The genus Coolia includes potentially harmful species and the diversity within the genus is just starting to become apparent. Methodology/Principal Findings
Elements and Compounds Elements, Atoms, and Molecules For a more advanced list of resources on atoms, elements and compounds Elements are substances that cannot be separated into simpler substances. Salt is made up of the elements sodium and chloride. Water is made up of the elements hydrogen and oxygen. How 29 Long-Ignored Elements Could Make or Break the Clean-Energy Revolution In December 2006, William Tahil, an energy analyst, published a paper online titled "The Trouble with Lithium." His argument would be alarming to the many people who had placed their hopes for a cleaner, more prosperous economy on the rapid development of electric cars powered by lithium-ion batteries. The trouble, he proposed, was that the world didn't contain enough economically recoverable lithium to support such a switch. Moreover, the viable pockets of lithium that did exist were concentrated in just a few countries. "If the world was to swap oil for Li-Ion based battery propulsion," he wrote, "South America would become the new Middle East. Bolivia would become far more of a focus of world attention than Saudi Arabia ever was.
Messier Monday: Andromeda, the Object that Opened Up the Universe, M31 “We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe.” -Edwin Powell Hubble With 110 deep-sky objects scattered throughout the heavens, the Messier Catalogue provides skywatchers across the globe with a number of spectacular targets, from nearby nebulae and clusters to spectacular, distant galaxies. Each Monday, we spotlight a new one right here. Image credit: Rolando Ligustri, taken over many years, retrieved from
What is chemical energy? Chemical energy Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product (exothermic reaction). Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Usually, once chemical energy is released from a substance, that substance is transformed into an entirely new substance. 10 elements crucial to modern life that you've probably never heard of We live in a complicated world. Our lives are driven by unfathomably complex systems that overlap in a cacophony of technology to deliver us our cellular service, Internet, groceries, health care, transportation, consumer goods, music, TV, movies and everything in between. One of the results of our headlong rush into a technologically augmented world is a veritable mountain of equipment. Our cultural relics are now iPads and iPhones, Androids and laptops, each made up of thousands of components, each component potentially made up of thousands of sub-components themselves.
