NSDL is the nation's online portal for education and research on learning in Science, Technology, Engineering, and Mathematics. The National Science Digital Library has a wealth of high quality digital resources to teach almost any topic in K-12 math and science. NSDL has constructed the following collections of "resource packs" for teaching to particular K12 subject areas, drawing resources from NSDL Pathways and other NSDL projects, and gathering these topical resource sets into a single location.

TeachUNICEF is a portfolio of free global education resources. Resources cover grades PK-12, are interdisciplinary (social studies, science, math, English/language arts, foreign/world languages), and align with standards. The lesson plans, stories, and multimedia cover topics ranging from the Millennium Development Goals to Water and Sanitation. Our mission is to support and create well-informed global citizens who understand interconnectedness, respect and value diversity, have the ability to challenge injustice and inequities and take action in personally meaningful ways. We hope that in providing engaging and academically rich materials that offer multiple voices, we can encourage the exploration of critical global issues while presenting opportunities to take action.

The National Park Service Air Resources Division in an effort to increase the public's awareness of air quality issues has developed a series of five activities for elementary and secondary schools. The activities are for grades six through eight and help teach students about Acid Rain. The lesson plan was prepared as a part of The Uplands Field Research Laboratory, Volunteer in Parks, and Interpretation of Science Project. Funding was provided by the Great Smoky Mountains Natural History Association.

The online textbook provides a background to understand and discuss the natural functioning of the different Earth systems; it introduces humans as part of the overall ecosystem and explores what is needed to sustain human life; and it looks at the effects that human actions have on different natural systems. The online textbook also includes full-color images of related figures, glossary terms, and a bibliography for further reading.

Extensive lessons from hands on inquiry lab at University of Rochester, developed/written with research funds.

To promote understanding and awareness of the importance of agriculture. Our educational programs provide a wealth of opportunities for embedding agriculture, food and natural resources education into the K-12 classroom. MAITC seeks to improve student achievement by applying authentic agricultural examples to teach core curriculum concepts in science, social studies, language arts, math and nutrition. These programs cultivate an understanding and appreciation of the food and fiber system that we all rely on every day.

Movement of ions in and out of cells is crucial to maintaining homeostasis within the body and ensuring that biological functions run properly. The natural movement of molecules due to collisions is called diffusion. Several factors affect diffusion rate: concentration, surface area, and molecular pumps. This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models. Start by following the path of a molecule of dye in water, create concentration gradients on either side of a cell membrane and watch the movement of substances in and out of a cell, and monitor the movement of oxygen into red blood cells with and without hemoglobin.

We're taking a systems approach to learning about the Earth using real scientific data. Our goal is to design easy-to-use curriculum activities and simple, intuitive computer interfaces for accessing online data. It's all part of a NOAA-supported effort called the NODE Project.
