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

Two Unreconciled Strivings: African-American Identity in the Gilded Age, 1877-1915
Examine the tension experienced by African-Americans as they struggled to establish a vibrant and meaningful identity based on the promises of liberty and equality in the midst of a society that was ambivalent towards them and sought to impose an inferior definition upon them. The primary sources used are drawn from a time of great change that begins after Reconstruction's brief promise of full citizenship and ends with the First World War's Great Migration, when many African-Americans sought gr

Active Lessons
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

Puzzling Polarizers
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.

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)

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
