Currently, AAAS STEM Education is working on Spanish-language STEM resources, we recognize the importance of having them available for teachers, students, and families. Until the resources are published, we compiled eight free CTIM (ciencias, tecnología, ingeniería, y matemáticas) educational collections and resources that we think are useful:

EXPLORATORIUM

The Exploratorium created a collection of free, Spanish-language science activities, Bocadillos científicos. The collection includes general science activities designed for elementary-aged learners that utilize inexpensive, readily available materials, and support educators working in virtual classrooms and at-home learning. They will continue to add Spanish-language activities to this collection over time. Users can keep track of updates by following the Exploratorium on Twitter and #ExploEDU.

HHMI BIOINTERACTIVE

Not all of the Howard Hughes Medical Institute's BioInteractive site is bilingual, but they do have a collection of more than 80 short films, animations, classroom materials, and interactive features focusing on the life sciences that are available in Spanish. Resources for high school students range from an interactive calculator to help determine a household's carbon footprint to a lab simulating lactose intolerance to animated short films.

KHAN ACADEMY

Khan Academy, a nonprofit created by an MIT alumnus with the intention of providing free educational materials online, has translated their website into Spanish. They offer classes aimed at students (of any age) in grades K-12, which are presented free of charge. Courses include math (from early math and arithmetic to calculus), science (biology, chemistry, phsyics, and electrical engineering), and computer programming (from Hour of Code basic classes to Javascript, SQL, HTML and CSS), among other topics.

PEEP AND THE BIG WIDE WORLD

Peep and the Big Wide World is an animated series available online and on many public television networks that teaches preschoolers about science and math through fun and easy hands-on activities and is available in both English and Spanish. There are videos, apps, coloring pages, and more on topics from water to color to ramps.

SCIGIRLS EN ESPAÑOL

SciGirls, an award winning PBS KIDS series, website and national outreach initiative, is changing how millions of girls think about science, technology, engineering and math, or STEM! The educational resources are in Spanish and English, as well as customized professional development training and funding for nine Latina-serving programs throughout the United States. See a list of SciGirls en Español groups.

SEED EARTH SCIENCE WEEK ONLINE TOOLKIT

The SEED Earth Science Week Online Toolkit, developed by Schlumberger Excellence in Educational Development (SEED) and the American Geophysical Institute, provides educational materials, activities, and other resources in both Spanish and English. Materials range from introductory information on Earth science to fact sheets about living in earthquake zones to science notebooks where students can record their observations about the world around them.

WINDOWS TO THE UNIVERSE

Windows to the Universe, created by the National Earth Science Teachers Association, is designed to encourage learning about the Earth and space sciences. It offers its website at three levels of both English and Spanish to allow students of various ages and abilities to access the site and understand the information found there. There is a lot of information found on this site, from star maps to hands-on activities and from listings of science fiction-themed films to information ranging from space exploration to climate change.

AAA MATH

AAA Matematicas covers a range of math aimed at students in preschool to eighth grade, providing basic information and interactive Javascripts-based practice that offers instant feedback. The site can be formatted to offer students measurements in English and/or in metric and to use either a comma or a period to express decimals, depending on where they live or the system with which they're familiar. Topics range from money and counting to geometry and statistics.

If you have other favorite Spanish-language STEM resources or collections you recommend, please leave them in a comment. If we get enough, we may compose a second roundup!
