This video segment from Wild Europe: "Wild Arctic" explores the struggle for survival in one of Earth's most extreme environments.

This course teaches simple reasoning techniques for complex phenomena: divide and conquer, dimensional analysis, extreme cases, continuity, scaling, successive approximation, balancing, cheap calculus, and symmetry. Applications are drawn from the physical and biological sciences, mathematics, and engineering. Examples include bird and machine flight, neuron biophysics, weather, prime numbers, and animal locomotion. Emphasis is on low-cost experiments to test ideas and on fostering curiosity about phenomena in the world.

Explore some of the wonders of modern engineering in this video from the Sciencenter in Ithaca, New York. Hear a diverse selection of engineers explain how things work.

The numerical methods, formulation and parameterizations used in models of the circulation of the atmosphere and ocean will be described in detail. Widely used numerical methods will be the focus but we will also review emerging concepts and new methods. The numerics underlying a hierarchy of models will be discussed, ranging from simple GFD models to the high-end GCMs. In the context of ocean GCMs, we will describe parameterization of geostrophic eddies, mixing and the surface and bottom boundary layers. In the atmosphere, we will review parameterizations of convection and large scale condensation, the planetary boundary layer and radiative transfer.

Novel representations and diverse perspectives can reveal new insights into complex systems, and can support rich understandings of the world. In this activity, students will identify and analyze the choices artists and scientists make when creating representations of living or non-living natural objects. This process will help students recognize the potential and place for their own articulation of how the world works. After drawing from nature, students will reflect on the process of representing information, then compare their drawings with that of a 16th-century artist. Students will consider what is included and what is excluded, and hypothesize about larger contexts and systems.

Students explore static electricity by rubbing a simulated balloon on a sweater. As they view the charges in the sweater, balloon, and adjacent wall, they gain an understanding of charge transfer. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

In this video segment from Nature, learn about the problems bears are creating on ranch land surrounding Yellowstone National Park.

This series of 5 high-quality, standards-aligned, inquiry-based activities have been field-tested by first grade students and families of Wequiock Children's Center for Environmental Science during Safer At Home orders. These activities encourage students to use natural areas around their homes and in their neigbhorhoods as they improve their science observation skils. The materials used are ones generally available at home and the activites require little preparation on the part of caregivers.Created as a part of a WISELearn OER Innovation project, Connect, Explore, and Engage: Using the Environment as the Context for Science Learning was a collaboration of the Wequiock Children's Center for Environmental Science and the Wisconsin Green Schools Network. One of the goals of the project was to create standards-aligned lessons that utilize the outdoor spaces of the school (as well as those of the students' homes).  Each section of this resource is an individual activity. While each activity builds on the previous ones, it is possible to use them individually.The observation protocol "I Notice, I Wonder, It Reminds Me Of, I Think Maybe" has been adapted from that of the BEETLES Project.The title image was used with permission and is courtesy of Joe Riederer.

In this autobiographical account of the life that awaited new nursing recruits in 1893, former nurse Mary Roberts Rinehart painted a vivid portrait of the daily obstacles that stood between nurses and the professional status they hoped to attain. Rinehart described the "simple, plain hell" faced by the young nurse, a description that challenged conventional expectations about professional work.

This course explores the physical, ecological, technological, political, economic, and cultural implications of big plans and mega-urban landscapes in a global context. It uses local and international case studies to understand the process of making major changes to urban landscape and city fabric, and to regional landscape systems. It includes lectures by leading practitioners. The assignments consider planning and design strategies across multiple scales and time frames.

Meet the Bio Builders—a team of scientists at the Thomson Lab who are using stem cells to repair damaged tissue and improve human health treatments.

Resources available for learning about this lab include:
• Interactive cards designed to introduce students to scientists in a more personal way
• A video with a personal story that explains why the lab's research matters in real life
• Questions to consider that will spark connection, reflection, and conversation
• An interactive video experience where you can ask questions of scientists in the lab and learn about their research
• An inquiry-based activity that focuses on doing science, using some of the same science practices that the lab uses
• An educator guide with information about standards alignment, curriculum connections, and tips for using the media resources

These resources are part of Meet the Lab, a collection of educational resources for middle school classrooms.

This peer-reviewed publication contains over 70 MAC and PC tools, simulations, databases, and other resources developed for undergraduate biology.

In this video segment adapted from NOVA scienceNOW, scientists discuss their attempts to grow human body parts in a jar.

Students have the opportunity to read through a bioethical scenario related to biotechnology, then answer a few discussion questions related to the reading  I have students read one scenario on their own and highlight the FIVE most important ¨facts¨ of that scenario (I tell students there isn´t a wrong answer, they can highlight which ever pieces they feel are the most important from the reading- this allows different viewpoints to be demonstrated when they do the next part)  Then students get into a small group with others that read the same scenario.  They first discuss which items they each highlighted and what they thought about the article.  Next I hand out the discussion questions related to their reading passage and have the students answer the questions as a group.    For the last part of the discussion, I have students regroup so that each new group has ONE person from eaching reading passage.  Students share out a quick summary of their passage and then ask the new group if they think biotechnology should continue related to the information in the article.  If time permits, we have a whole class discussion about the ethics behind biotechnology and the different examples demonstrated in the reading passages.  

Throughout the day, your nervous system monitors and makes endless adjustments to your body's basic systems -- all to keep you alive. This interactive feature illustrates the complexity of such a task.

In this online game, learners test their knowledge of human anatomy. Learners are presented a mystery image of a body part and use their mouse to select the proper body part from a full size anatomical model (known as "Jerome"). Learners try to match all 10 body parts correctly. Use this activity to review human anatomy and/or introduce learners to the use of anatomical models.

This video segment from The Human Spark observes the brains responses to a series of cognitive tests.

In this demonstration of chemical change, the presenter blows breath into a methylene blue solution releasing carbon dioxide which acidifies the water and changes it from a bright blue color to green.
