 is a web-based library of inquiry-based character-driven animated mysteries paired with differentiated supplemental activities that exposes students to the thrill of problem-solving. Mosa Mack allows educators to engage students while teaching standards-aligned content in a fun and engaging way while modeling scientific processing skills. Through its female protagonist whose passion for problem solving drives each story, Mosa Mack promotes diversity in the sciences while simultaneously providing teachers with an accessible way to incorporate inquiry into the classroom. Mosa Mack's unique inquiry-based approach targets the development of critical thinking skills for all students, with a particular focus on girls and minorities with historically low participation STEM fields.

This groundbreaking NRDC documentary explores the startling phenomenon of ocean acidification, which may soon challenge marine life on a scale not seen for tens of millions of years. The film, featuring Sigourney Weaver, originally aired on Discovery Planet Green.

And as the El Nino weather system has been storming across the Pacific this season, it has stirred up ocean waters enough to cool down the original Blob off of Alaska, but at the same time helped give birth to what has been nicknamed the "Son of Blob" off the coast of Southern California. The still-warmer Alaskan waters, and Son of Blob sector are expected to continue to magnify the El Nino effect for months to come, according to Weather Underground's "Blob Watch" blog.

An international team led by Professor Itai YanaAi of the Technion-Israel Institute of Technology Department of Biology made the discovery after using an extraordinarily powerful technique known as CEL-Seq. CEL-Seq monitors individual cells for their gene activity (as detected via mRNA)-and they applied it across 10 different species, with CEL-Seq being applied to 70 embryos per species. In particular, they were interested in whether the animal classification of phylum-which separates animals into groups according to their body plans-is actually a useful tool for placing animals into groups, as well as what genetic attributes are the same and different between the different phyla.

In this interrupted case study developed for use in a flipped classroom, students read about a picnic that takes place in autumn during the peak of fall color and along the way learn about light absorption by photosynthetic pigments, why leaves turn color in the fall, atmospheric CO2 concentrations and their effect on photosynthesis, and the C3, C4, and CAM photosynthetic pathways. The case is designed to provide introductory biology students with a basic understanding of photosynthetic pathways and how environmental factors affect plants using these pathways. The activity could also be used in an advanced high school biology course covering photosynthesis. The case includes several short videos that students watch as homework before coming to class so that they are prepared to work together in class in small groups to answer the case questions.

Scientists have discovered a previously unrecognized genus of extinct horses that roamed North America during the last ice age. The new findings are based on an analysis of ancient DNA from fossils of the enigmatic 'New World stilt-legged horse'

Are you interested in using authentic Arctic and MOSAiC expedition data in your classroom? Look no further! Data Puzzles allow your students to analyze and interpret real scientific data and develop skills in hypothesis testing, graphing, and more.

"What is Ambitious Science Teaching? Great teaching can be learned. This web site provides a vision of ambitious science instruction for elementary, middle school and high school classrooms. Ambitious teaching deliberately aims to support students of all backgrounds to deeply understand science ideas, participate in the activities of the discipline, and solve authentic problems. We feature 4 core sets of teaching practices that support these goals. These core sets make up the Ambitious Science Teaching Framework. The framework has been based on classroom research from the past 30 years-research that has asked, "What kinds of talk, tasks, and tools do students need in order to fully engage in meaningful forms of science learning?""

Managing manure to reduce emissions can be economically viable for larger enterprises or cooperative facilities that use the captured methane to generate heat and electricity. For small operators, the offset value alone is unlikely to warrant the large capital cost of infrastructure. This activity contributes to carbon farming. Agriculture is responsible for 14% of Australia's greenhouse gas emissions and is the dominant source of methane and nitrous oxide, accounting for 56% and 73%, respectively, of Australia's emissions.
