An interactive applet and associated web page that demonstrate the concept of arc length. The applet shows a circle with part of its circumference highlighted and the central angle shown. As the user drags either end of the arc it is redrawn and the calculation for arc length changes as you drag. The text on the web page gives the formula for calculating the arc length. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the concept of the peripheral angle (inscribed angle) of an arc. This is the angle subtended at the circle circumference of an arc. The applet shows an arc with draggable end points and the angle it subtends at the circumference. It is seen that this angle is constant for a constant arc length. It shows also what happens when the vertex is inside the arc that subtends it The web page has links to other arc properties and a formula for the subtended angle for a given arc length. Applet can be enlarged to full screen size for use with a classroom projector.

Students working collaboratively on a mini-archaeology dig to locate and identify artifacts, create hypotheses about the objects and what information they tell us about a society, and research past artifacts to determine if their hypotheses were correct. Students had to use collaboration when working on the dig, when creating their hypotheses, when measuring the artifacts, and when forming conclusions. Additionally, students had to use critical thinking when formulating theories, researching and reviewing data online, assessing their ideas, analyzing and comparing their hypotheses with archaeology studies online, and when justifying their hypotheses (and proving them) with the artifact data they discovered online, and forming conclusions.

In which John Green teaches you about the war that was supposed to end all wars. Instead, it solved nothing and set the stage for the world to be back at war just a couple of decades later. As an added bonus, World War I changed the way people look at the world, and normalized cynicism and irony. John will teach you how the assassination of an Austrian Archduke kicked off a new kind of war that involved more nations and more people than any war that came before. New technology like machine guns, airplanes, tanks, and poison gas made the killing more efficient than ever. Trench warfare and modern weapons led to battles in which tens of thousands of soldiers were killed in a day, with no ground gained for either side. World War I washed away the last vestiges of 19th century Romanticism and paved the way for the 20th century modernism that we all know and find to be cold and off-putting. While there may not be much upside to WWI, at least it inspired George M. Cohan to write the awesome song, "Over There."

Students will examine the use of the elements of art, including line, shape, form, texture, and color, in a drawing. They will also study the elements of architecture and learn to identify architectural elements in detail and their relationship to the surrounding landscape. Then students will draw an ancient Roman temple in perspective, integrating architectural elements in the drawing.

Students create four-legged walking robots and measure how far they travel across different types of surfaces. They design and create "shoes" to add to the robots' feet and observe the effect of their modifications on the net distance traveled across the various surface types. This activity illustrates how the specialized locomotive features of different species help them to survive or thrive in their habitat environments. The activity is best as an enrichment tool that follows a lesson that introduces the concept of biological adaptation to students.

“Arctic Feedbacks” is a middle/high school earth science unit focused on weather and climate as it relates to Earth’s system. The unit is centered around an anchoring phenomena known as Arctic amplification and consists of ten unique lessons, each tied to the NGSS Earth’s systems standards. Each lesson provides students with evidence they will use to explain anchoring phenomena in a final descriptive model and written explanation.

Originally conceived of as a curriculum resource for Nunavut schools, this comprehensive interactive presentation provides an excellent introduction to the arctic, and to the people who made this environment their home for the past thousands of years.
The presentation begins by introducing the arctic environment. An interactive migration activity concludes this first section, encouraging the student to consider the challenges of a family at the turn of a season as they decide where to travel next to find the sustenance on which their lives depend. The next section introduces the arctic peoples, their tools, shelters, and their modes of transportation.
The third section introduces the science of archaeology along with the regulatory environment for accessing archaeology sites in Nunavut today. The final section focuses on a rich archaeological site in the High Arctic. This section is also interactive, requiring the student’s assistance to identify objects and make decisions about the Tuniit and the Thule who were known to have occupied this site.

Students learn that dams do not last forever. Similar to other human-made structures, such as roads and bridges, dams require regular maintenance and have a finite lifespan. Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years. The engineers with Splash Engineering have an ethical obligation to remind Thirsty County of the maintenance and lifespan concerns associated with its dam.

In this problem, students are given a picture of two triangles that appear to be similar, but whose similarity cannot be proven without further information. Asking students to provide a sequence of similarity transformations that maps one triangle to the other focuses them on the work of standard G-SRT.2, using the definition of similarity in terms of similarity transformations.
