A hypothesized mechanism for the origin of life, an event called abiogenesis.  In this version, called RNA world, small molecules called nucleotides formed in the waters of the early Earth during the Hadean Eon, and polymerized on the surface of clay minerals.  These simple chains of RNA could replicate themselves in solution, but only slowly and inaccurately.  An RNA molecule developed which would fold into a structure that catalyzed RNA polymerization; a ribozyme.  The first ribozymes would replicate their sister strands, and produce copies of themselves and other RNA molecules. 

     In the same environment, long chains of carbon molecules called phospholipids were formed.  These molecules have two parts, the tail, which is hydrophobic, and the head, which is hydrophillic.  Because of these properties phospholipids will stick together and form micelles and vesicles in water.  Vesicles can absorb RNA nucleotides, concentrating them and creating a space where they can replicate, mutate and evolve.  At some point a ribozyme became enclosed within a vesicle, starting a chain reaction that evolved into the multitude of biological forms that we see today.

   Because this event occurred more than 3.8 billion years ago, theories about how and where it happened are highly speculative.  Possible environments for abiogensis include hydrothermal vents on the ocean floor, hyper saline bubbles of water trapped in ice, radioactive lakes or lagoons on earths surface, and even in space or on another planet, brought to earth through a panspermia event.  We have very little molecular evidence of the first cells, but ribozymes and catalytic RNA molecules are embedded in the DNA replication machinery of all life.  Because evidence of this event has almost certainly been lost to time, the true mechanisms of the origin of life may remain a mystery to science.

What is STEM, exactly? If you have followed Groovy Lab in a Box for a while, you may have noticed that we reference “STEM” a lot. However, you may be wondering: “What is STEM, exactly?” Let’s take a look at what STEM is and why it is so important to the United States. STEM is an acronym for “#Science, #Technology, #Engineering and #Mathematics.” It’s an acronym to describe a type of curriculum in school – from kindergarten through college. The idea behind STEM is to make the United States more competitive in technology development by bringing up generations of students who can excel in high-tech jobs (we call this generation, #STEMists.) Right now, only 16% of children graduating from American high schools are proficient in math and interested in a STEM career. However, jobs such as systems software developers, medical scientists and biomedical engineers will have the most career opportunities by 2020. Emphasizing STEM is critical in our schools, and it has not gone unnoticed by our federal government. In May 2013, the National Science and Technology Council issued a five-year strategic plan to respond to the lack of STEM education in our country’s schools. Other organizations, such as the STEM Education Coalition, are working hard to tell policymakers about STEM and how preparing our students is critical to the future of the U.S. We are doing our part, too. Each month, our subscription service focuses on delivering STEM education to your doorstep and computer. At Groovy Lab in a Box, we believe that children are natural STEMists with an innate sense of curiosity and inquiry that can flourish under the right conditions. We also believe that learning can be fun. We created Groovy Lab in a Box to encourage children to channel their natural STEMists. Whether they are building rockets or creating an electrical circuit, children are enjoying the learning process, and applying analytical skills that will transfer to the classroom, and later, their careers.
