A Colonial Legacy in Miskito Turtle Knowledge (Nicaragua)
Over the past several decades the increasing prevalence of natural resource crises has led many ecologists to seek alternatives to Western resource use paradigms. Primary amongst these alternatives are systems guided by indigenous knowledge (IK). It is commonly presumed that these systems represent institutions uncorrupted by the exploitative hand of Western culture and state domination and therefore hold the key to rectifying the unsustainable behaviors of Western societies.
Who Has? Multiplication Activities
Once students have developed conceptual understanding of the basic operations they need to develop fluency with the facts. One quick way to include daily practice and motivate students to master these basic facts is through the use of the Who Has? card decks. These decks can be created for virtually any topic and frequent use as both a whole class practice or as a center activity for partners or small groups will provide facts practice in a highly-motivating format.
Hundred Board Activities 2
Students use "magic" to navigate around the hundred board. This activity introduces horizontal arrows which mean move one square in the direction the arrow points and vertical arrows which mean move up or down one row in the direction the arrow points. These activities support students as they develop understanding of powerful number patterns in the hundred board: (1) moving across or back one space means adding or subtracting one from the starting number; (2) moving up or down one row means add
Math Tours: Fractions
Students need many concrete experiences with fractions to develop a deep understanding of the three models of fractions: area, linear and set models. Teachers need to address all three models in well-designed instructional activities so that students develop a rich concept of fractions that they can use to make sense of numbers, operations, measurement and probability. The Math Tours include: activities, problem solving, games, writing to learn, templates, math-literature connections, and web li
Gingerbread Man Math
Gingerbread men and gingerbread houses enjoy special popularity around the holidays, but many of these gingerbread activities are timeless and complement literature titles that teachers use at the beginning of school or after the holidays. It's very easy to incorporate mathematics into a study of gingerbread men, and students will enjoy the data collection activities and games while learning math skills and deepening their understanding of important mathematical concepts. Look through these math
Algebra: Growing Patterns
Introduce elementary students to the concept of functions by investigating growing patterns. Visual patterns formed with manipulatives are especially effective for elementary students and allow them to concretely build understanding as they first reproduce, then extend the pattern to the next couple of stages.
War and Peace
Gain insight into wars by studying maps, letters, and historic newspapers. Consider women’s roles during the Civil War and World War II. See film clips of the Spanish-American War, the first war to be captured on film. Listen to recordings from World War I and the 1920 Election. Analyze Ansel Adams’ photo documentary of life at Manzanar to deepen understanding of Japanese internme
Active Lessons are engaging, technology-based, student-centered (pupil-centered) learning activities designed by teachers using PowerPoint (or other presentation tool). The idea is to empower teachers to easily create technology-based activities that draw upon variety of existing and new digital resources from internet, repositories of learning objects and other sources, and require students to use technology and create artifacts demonstrating their understanding. This idea partially challenges
Selenium: A Window on Wetlands Activity
Wetlands are natural recycling plants, but they are often endangered by the waste people put there. Understanding the complex processes that enable a marsh to clean water, recycle nutrients, and immobilize toxic elements will help us protect these diminishing resources. Bring the scientific research done at the the Advanced Light Source into your classroom using this complete teaching module.
When we apply the scientific method to real-world problems, often we can invent applications for the effects we observe even without understanding the origins of those effects. This process is commonly used in the development of new technologies; one example is the discovery of x rays. This curriculum unit is designed to encourage this investigative process through inquiry-based learning involving exploring, observing, and then applying the information gained. Light and its interactions with mat
Reading for Philosophical Inquiry
In this introduction to philosophical thinking, we will read some essays specially chosen from four main areas of interest: (1) the philosophy of life, (2) the philosophy of religion, (3) ethics, and (4) metaphysics and theory of knowledge. Although our approach is not comprehensive, it is reasonably representative of some of the more significant areas of philosophical inquiry. The readings are intended to illustrate the interrelations between these subject areas of philosophy and, as well, to p
Journey North Journals: Helping Young Minds Grow
This teachers' lesson offers tips on using Journey North journals to inspire learning and assessment. When students use journals to capture and reflect on observations, experiences, and data — and put forth opinions, predictions, and theories — learning blossoms. These records can also be great assessment tools because they offer you and your students windows into their thinking, understanding, and knowledge gaps. Finally, they can help you address pressures to integrate writing into subject

Crash: A Tale of Two Species
This is the story of the fabric of life, and how all species are connected. At its center is the horseshoe crab, a creature that has remained virtually unchanged for eons. Its annual spawning produces millions of eggs that are the lifeline for a tiny bird, the red knot. But horseshoe crab numbers are plummeting, and the pyramid depending on this age-old creature is about to come crashing down. (50:44)
What is Remix Culture
This resource is a playlist containing pointers to many other resources. This playlist is dedicated to understanding exactly what is meant by "Remix" and "Remix Culture. It goes through to first define and explain the terms and the phenonmenon, then to explain the implications of them, and finally give useful and interesting examples.
Understanding Computers and the Internet
This course is all about understanding: understanding what's going on inside your computer when you flip on the switch, why tech support has you constantly rebooting your computer, how everything you do on the Internet can be watched by others, and how your computer can become infected with a worm just by turning it on. In this course we demystify computers and the Internet, along with their jargon, so that students understand not only what they can do with each but also how it all works and why
China Dust Storm during April 2001 (WMS)
A major dust storm occurred in April 2001 over parts of China and Mongolia. Dust from this storm was transported all the way to the coast of the United States. Although dust from the Sahara Desert is routinely transported across the Atlantic to the east coast of the United States, Asian dust rarely makes the distance across the Pacific to the west coast. These airborne microscopic dust and smoke particles, or aerosols, were measured by the TOMS instrument on the Earth Probe satellite. For govern
Making a Sundial
In this activity students construct a sundial and use it to observe the movement of the sun through the sky over the course of a day by marking changes in the position of a shadow once each hour. Students determine the approximate time of solar noon at their school as indicated by the time of the shortest shadow. They revisit the site on a subsequent day to estimate the time of day using their sundial. Intended outcomes are that students will gain an understanding of the daily movement of the su
GLOBE 1987 Global Patterns Poster
The purpose of the ESS activities associated with the GLOBE 1987 Global Patterns Poster is to help students understand the broader global context for local GLOBE measurements. Students discover patterns in global maps of environmental data, interpret those patterns, and draw conclusions and make predictions based on them; communicate those interpretations and predictions; and develop an understanding that the components of the Earth system interact. By completing this activity, students will gai
Elementary GLOBE: Water Wonders
Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates. in an aquarium in their classroom. For an optional extension, teachers can take students to a local stream or pond to conduct field observations. The purpose of this activity is to introduce students to hydrology and the study of macroinvertebrates. and to understand how macroinvertebrates. help scientists
