In this activity, students compare countries and nation states with high- and low-energy consumption rates within a specific region of the world. Students are encouraged to draw linkages between a country's energy culture and its position in multilateral climate negotiations.

This activity is an inquiry where students will design an electrolytic cell that produces work in the form of lighting a bulb.

In this lesson students will develop an evidence-based argument after investigating the product safety, performance, and cost of a variety of cleaning and disinfecting products designed to remove germs.  Students will be introduced to principles of sustainable design, life-cycle thinking, and how to identify safer products to certifications.Except where otherwise noted, this work by Saskia van Bergen (Washington Department of Ecology), Vickei Hrdina (ESD 112), and Carissa Haug (NCESD) is licensed under Creative Commons Attribution License 4.0.  All logos and trademarks are property of their respective owners.  

6.637 covers the fundamentals of optical signals and modern optical devices and systems from a practical point of view. Its goal is to help students develop a thorough understanding of the underlying physical principles such that device and system design and performance can be predicted, analyzed, and understood.
Most optical systems involve the use of one or more of the following: sources (e.g., lasers and light-emitting diodes), light modulation components (e.g., liquid-crystal light modulators), transmission media (e.g., free space or fibers), photodetectors (e.g., photodiodes, photomultiplier tubes), information storage devices (e.g., optical disk), processing systems (e.g., imaging and spatial filtering systems) and displays (LCOS microdisplays). These are the topics covered by this course.

After completing the various activities in this lesson, students will be able to understand the importance for a healthy body to be able to do an activity for 1 - 5 minutes.

This is a poster detailing the Sun and its impacts on the Earth. Learners will be introduced to space weather, solar storms, aurorae, and the spacecraft that study the Sun and its impacts.

We will study the fundamental principles of classical mechanics, with a modern emphasis on the qualitative structure of phase space. We will use computational ideas to formulate the principles of mechanics precisely. Expression in a computational framework encourages clear thinking and active exploration.
We will consider the following topics: the Lagrangian formulation; action, variational principles, and equations of motion; Hamilton’s principle; conserved quantities; rigid bodies and tops; Hamiltonian formulation and canonical equations; surfaces of section; chaos; canonical transformations and generating functions; Liouville’s theorem and Poincaré integral invariants; Poincaré-Birkhoff and KAM theorems; invariant curves and cantori; nonlinear resonances; resonance overlap and transition to chaos; properties of chaotic motion.
Ideas will be illustrated and supported with physical examples. We will make extensive use of computing to capture methods, for simulation, and for symbolic analysis.

This activity describes a simple clear demonstration of electric generators (Faraday's Law) and electric motors (Lorentz Force). This demonstration can be used as an interactive lecture demonstration.

Investigate how torque causes an object to rotate. Discover the relationships between angular acceleration, moment of inertia, angular momentum and torque.

The students are exposed to a brief (approx. 5 minute) introduction/presentation on aquifers and groundwater including their geographical context, structure, and vocabulary.

The students receive everyday materials with different properties: Styrofoam block, scrubbing pad, etc, and a dropper bottle filled with water. They are not initially told what to do, but instead asked what they are going to do. The idea is to use the dropper bottle to put water on the objects and notice if the water passes through or not? They are also encouraged to notice any physical features that may be responsible for these behaviors. Students typically won't talk to each other at first and won't know what to do. Asking them guided questions usually encourages conversation between the students. They can also be asked what other everyday objects could be used for this exercise.

After they have explore everyday objects, they are introduced to a handsample of granite and a sandstone. Although they have not been exposed to rocks in lab, they can usually identify the granite right away, and the sandstone when about the size of the grains. They then will discuss the physical properties of the rocks and hypothesize what is more porous and permeable. They test this with the water dropper.

Finally, as a class, we discuss that something that is porous and permeable like a sandstone makes a good aquifer, and where good aquifers are located.

This is a field and computer laboratory exercise that introduces undergraduate students, advanced high school students, and members of the general public to using Google Earth, GPS, aerial imagery, and an online illustrated vegetation and tidal marsh environment identification guide to distinguish and map vegetational and physical environmental zones within a salt marsh. They also learn about the physical and ecological relationships between these environments.

Students use GPS devices to collect field data as waypoints and tracks, and upload the data to computers in GPX format. They learn to open the data in Google Earth along with infrared and color aerial imagery, and use the GPS data to interpret the aerial imagery. Using Google Earth tools, they draw polygons to demarcate the boundaries of environmental zones in the wetlands that they recognize on the imagery.

The students and instructors also take photographs of the students in each of these environmental zones and embed the photographs into information balloons of placemarks in Google Earth.

The exercise was originally designed for use at Flax Pond, a salt marsh on the North Shore of Long Island. However, it can easily be adapted for use in other tidal marshes, and can serve as a template for developing similar activities to be conducted at other locations in which aerial imagery can be used to distinguish various forms of land cover.

This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas. Based on an activity presented by Olaf Runquist, Professor, Hamline University.

This is an activity about image comparison. Learners will analyze and compare two sets of images of the Sun taken by instruments on the Solar Dynamics Observatory spacecraft. With Set 1, they will observe the Sun in both a highly active and a minimally active state, and be able to detect active regions and loops on the Sun by comparing the two images. With Set 2, they will identify areas of high magnetic activity on a magnetogram image and recognize that these areas correspond to highly active regions on the Sun.

In this lesson, students learn about human resources, productivity, human capital, and physical capital. They participate in three rounds of a reasoning activity. From round to round they receive training and tools to help them improve their reasoning ability and thus increase their productivity. Students will then listen to a story about how the Empire State Building was built and identify examples of key concepts mentioned or shown in the book.

This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.

This Module offers a description of related services and an overview of the benefits they provide to students with disabilities in the general education classroom. It highlights five commonly used related services (Physical Therapy, Occupational Therapy, Speech-Language Pathology Services, Social Work Services, and Psychological Services) and briefly highlights many of the other related services as identified through IDEA '04 (est. completion time: 1 hour).

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.

This book is about complexity science, data structures and algorithms, intermediate programming in Python, and the philosophy of science. This book focuses on discrete models, which include graphs, cellular automata, and agent-based models. They are often characterized by structure, rules and transitions rather than by equations. They tend to be more abstract than continuous models; in some cases there is no direct correspondence between the model and a physical system.

With the emerging genetic testing companies such as “23 and Me” and “Ancestry”, it is becoming more popular and accessible for families to test their own genes rather than from a primary care provider. The purpose of this activity is to analyze multiple angles of genetic testing. Students will look at multiple areas of health including mental, emotional, and physical health and how it can impact their personal health and the health of loved ones.
