With support from an NSF grant, Smithsonian Science Education Center developed the Science and Technology Concepts Program™ (STC™): A basal, science and engineering-practices centered program for grades K-10.
Each STC™ unit provides opportunities for students to experience scientific phenomena firsthand. The units cover life, earth, and physical sciences with technology.
The Smithsonian Science Education Center received a 5-year, $30 million Investing in Innovation (i3) grant to improve K-8 science education. We are working with researchers, communities, districts, schools, and teachers in three regions to evaluate the effectiveness of our inquiry-based science education model (LASER: Leadership and Assistance for Science Education Reform).
A Community of Support
The LASER model addresses classroom instruction using a research-based science curriculum with aligned professional development for teachers. LASER also provides the entire support system with excellent science education. This prepares students for the opportunities of our 21st century economy.
Diversity of Classrooms
Our goal is to develop practices and procedures that can be replicated in other schools, districts, and states. LASER i3 is currently working with over 75,000 students and 3,000 teachers from urban and rural schools in grades one through eight. Learn more
Founded in 1846, the Smithsonian is the world's largest museum and research complex, consisting of 19 museums and galleries, the National Zoological Park and nine research facilities. The Smithsonian Science Education Center (SSEC) was established by the Smithsonian and the National Academies in 1985. Its mission is to improve the learning and teaching of science for all students in the United States and throughout the world. Go to the Smithsonian home page.
The sea was first named by the ancient Greeks who called it “Inhospitable Sea.” The sea got this reputation because it was difficult to navigate, and hostile tribes inhabited its shores. Later, after the successful development of the coast by Greek colonists, the sea was renamed “Hospitable Sea.”
The Black Sea has a depth of over 150 meters, and its waters are filled with hydrogen sulfide for almost two kilometers. Therefore, in the deepest layers of its water there are no living things except sulfur bacteria.
There are a number of hypotheses for why it was eventually called the Black Sea:
Metal objects from ships, dead plants, and animal matter that sunk deeper than 150 meters for a long period of time became covered with a black sludge due to the high concentration of hydrogen sulfide in the sea.
From the perspective of sailors, the sea was black due to severe storms in the winter, during which the water is so dark it looks black.
