Electrostatics
Students use a Although atoms contain both negatively and positively charged particles, they do so in equal amounts and carry no net charge. This balance can be temporarily disrupted by rubbing one material against another. One device, known as a Van de Graaff generator, uses a fast moving rubber belt to charge a metallic dome to nearly 200,000 Volts. This activity uses a Van de Graaff generator to study the behavior of electrical charges.

Travel to Identity in the Mid-Nineteenth-to-Mid-Twentieth-Century Contact Zone of New Mexico: Knowle
This study assesses narrative representations of Euro-American and Native American travel and encounter in New Mexico. The primary purpose of the work is to explore the construction and authority of knowledge claims and identity through late nineteenth- and early-to-mid twentieth-century Euro-American and Native American travel to, and within, the contact zone of New Mexico. I examine Willa Cather’s Death Comes for the Archbishop, Mabel Dodge Luhan’s Edge of Taos Desert: An Escape to Reali

MRI Safety Grand Challenge
This module was written for a first year accelerated or AP physics class. It is intended to provide hands on activities to teach end of the year electricity and magnetism topics including the magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's Law, and Faraday's Law. During the module, students utilize these scientific concepts to solve the following problem: A nearby hospital has just installed a new Magnetic Resonance Imaging facility, which has the capacity to make a th

Next steps
There is increasing recognition that the reductionist mindset that is currently dominating society, rooted in unlimited economic growth unperceptive to its social and environmental impact, cannot resolve the converging environmental, social and economic crises we now face. The primary aim of this unit is to encourage the shift away from reductionist and human centred thinking towards a holistic and ecological worldview.
Learning about Seasons
We will discover why we experience seasons and yearly changes in weather. Students will interview an adult they know and ask questions.

Chicken eggs
Eggs are the means through which chickens reproduce. Hens lay the eggs and incubate them so they will grow. The egg has all of the nutrients the chicken embryo needs to develop into a baby chick and helps protect it as it matures.
Chestnut shell
Squirrels use their teeth to bite into and crack open chestnuts and other kinds of nuts. Their teeth leave marks on the nutshell after the squirrel has cracked it open to get the nut that is inside.
The HoloGlobe Project
These animations were produced for the Smithsonian Institution's HoloGlobe Exhibit which opened to the public on August 10, 1996 at the Museum of Natural History in Washington, DC. The various data sets show progressive global change mapped onto a rotating globe and projected into space to create a holographic image of the Earth. The exhibit shows that Earth's atmosphere, hydrosphere, geosphere, and biosphere are dynamic, changing on timescales of days, minutes, or even seconds. The exhibit has
