Competition Eligibility Rules and Requirements - ExploraVision Each category will be judged separately, based on the abilities of students in those grades. Students in a lower grade may be part of a team competing in the next-higher category. However, students may not move down to a lower grade-level category. ExploraVision has four categories: Primary Level (Grades K – 3) Upper Elementary Level (Grades 4 – 6) Middle Level (Grades 7 – 9) High School Level (Grades 10 – 12) Each student may only submit one project per year.

Learn How Flocabulary Works Writing is a critical part of the learning process and is supported by research and standards, from Bloom's Taxonomy to the Common Core. When students write their own academic rhymes, they build essential writing skills and master content. Oh, and did we mention it’s fun? Explore our Writing Academic Rhymes lessons. What Recent Scientific Discoveries Could Change the World The number of scientific studies and discoveries each day is staggering: On March 17 of this year, scientists discovered rippling patterns in thermal radiation, which might be evidence for the Big Bang; they discovered a glacier in Greenland melting faster than expected, forcing revised estimates of global sea level rise; and a terrestrial ecologist revived moss specimens that had been frozen for more than 1,500 years. And what about today? What new information means very little outside of a very specific field, and what will crack a staid category wide open? It took 20 years and 2.2 miles of drilling, but Russian researchers finally reached Lake Vostok in February 2012. Fracking opponents might finally have their smoking gun: A study by the Colorado School of Public Health released this January linked living near a fracking site to increased risk of congenital heart disease in children by up to 30 percent. We’re telling stories all week on the theme of booms and busts.
Foldit Solve Puzzles for Science Exploratorium: the museum of science, art and human perception How the Physics of Football Works" When you throw a football across the yard to your friend, you are using physics. You make adjustments for all the factors, such as distance, wind and the weight of the ball. The farther away your friend is, the harder you have to throw the ball, or the steeper the angle of your throw. This adjustment is done in your head, and it's physics -- you just don't call it that because it comes so naturally. Physics is the branch of science that deals with the physical world. Delivery of a football through the airRunners on the fieldStopping runners on the field Watching a weekend football game could be teaching you something other than who threw the most passes or gained the most yards.
Climate Change, Deforestation, Biomes and Ocean Currents, Plankton, Endangered Species - Earth Web Site Click for more detail Thermohaline Change Evidence is growing that the thermohaline current may be slowed or stopped by cold fresh water inputs to the Arctic and North Atlantic oceans. This could occur if global warming is sufficient to cause large scale melting of arctic sea ice and the Greenland ice sheet. Such a change in the current may be gradual (over centuries) or very rapid (over a few years). Either would cause planet wide changes in climate. This effect may be part of what starts and stops the ice ages. "Diatoms (a kind of phytoplankton) are estimated to "scrub" roughly as much CO2 from the atmosphere each year as all the world's rainforests. "Net primary productivity is the mass of plant material produced each year on land and in the oceans by photosynthesis using energy from sunlight. Biodiversity is the variety of life found at all levels of biological organization, ranging from individuals and populations to species, communities and ecosystems. Click for more detail
Sea Level Rise Explorer - Global Warming Art From Global Warming Art Elevation Relative to Sea Level (m) Description The map shown above allows you to explore the regions of the Earth that are most vulnerable to sea level rise. As with other Google Maps, you can click-and-drag the window to scroll or double click to zoom. Potential for Sea Level Rise As global warming progresses, sea level is expected to rise primarily due to the melting of continental ice sheets in Greenland and Antarctica. During the twentieth century, sea level rose 20 cm. However, even if global temperatures stabilize in 2100, the full magnitude of sea level rise is expected to take far longer to develop. Accuracy of Maps The sea level data appearing in my maps is based primarily on version 2 of NASA's Shuttle Radar Topography Mission (SRTM), with post-processing by CGIAR to fill-in voids using data from other sources. The SRTM data are limited to a region of 60 S to 60 N latitude. Related Materials References ^ [abstract] [DOI] Knutti, Reto and Thomas F.
