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.

Some scientists think Earth’s oceans formed when icy comets hit the planet. But new research suggests a different origin for the oceans: they simply seeped out of the center of the Earth.
The finding, published in Science, suggests that a reservoir of water is hidden in the Earth’s mantle, more than 400 miles below the surface. Try to refrain from imagining expanses of underground seas: all this water, three times the volume of water on the surface, is trapped inside rocks.
Called ringwoodite, the rock is bright blue and is only formed at high temperature and pressure in the Earth’s mantle. The water would have been squeezed out of the rocks, “almost as if they’re sweating,” Steven Jacobsen of Northwestern University told The New Scientist.
