The goal of this task is to develop an understanding of why rational exponents are defined as they are (N-RN.1), however it also raises important issues about distinguishing between linear and exponential behavior (F-LE.1c) and it requires students to create an equation to model a context (A-CED.2

The latest releases from the National Aeronautics and Space Administration's (NASA's) Earth Observatory include a satellite image from GOES 11, the newest NOAA Geostationary Operational Environmental Satellite (GOES), showing smoke plumes and heat signature from many of the fires in the western United States, including those at Mesa Verde, on the evening of July 27, 2000. This summer is the worst fire season in four years. This page also provides links to information about GOES and to other remotely-sensed images, such as Mediterranean dust cover and Pacific typhoons.

An interactive applet and associated web page that demonstrate the exterior angles that are formed where a transversal crosses two lines. The applet shows the two possible pairs of exterior angles in turn when in animation mode. By dragging the three lines, it can be seen that the angles are supplementary only when the lines are parallel. When not in animated mode, there is a button that alternates the two pairs of angles. The text on the page discusses the properties of the angle pairs both in the parallel and non-parallel cases. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Through Problem based learning the students will take the perspective of a fictional character from the mid 1800’s to gain a perspective on the external forces that pushed Canada towards Confederation. The students will be given disclosures that guide them to further enquiry regarding topics like the U.S. manifest destiny, the British Corn Laws, the Treaty of Reciprocity, the U.S. Civil War, and the Fenian raids into Canada. Through this enquiry process, the students will be challenged to use the historical thinking concepts of: historical significance, continuity and change, cause and consequence, and historical perspective. Once the students have completed their research around all of the disclosures they will then need to write a speech that outlines what they believe to be the best course of action for the elected assembly of Canada to take, considering all of the external pressures that are on the British colonies of North America at this point in history. The students are required to be creative in their speech as they do not have any information in the disclosures that tells the students that these events would contribute to Canada’s Confederation in 1867.

Species extinction is happening at an alarming rate according to scientists. In this lesson, students are asked to consider why extinction is a problem that we should concern us. They are taught that destruction of habitat is the main reason many species are threatened. The lesson explores ways that engineers can help save endangered species.

This is a lesson about extremophiles and using DNA sequences to classify them. Learners will describe the characteristics of a newly discoverd thermophyllic organism and use the DNA sequence to place that organism in the phylogenetic tree of life. Includes teacher notes, learning objectives, and assessment of prior knowledge and preconceptions. This is Lesson 3 in Exploring Deep-Subsurface Life.

The ocean and atmosphere each react to changes in the other. These reactions and counter-reactions can snowball until the system builds to a point where potentially disastrous effects occur, such as the El Nino events of 1982-83 and 1997-98. This site describes how the Jet Propulsion Laboratory's TOPEX-Poseidon satellite was used to monitor the amount of sea level rise in the Eastern Pacific Ocean, and consequently the amount of heat stored in the water. Sea level and temperature data from TOPEX-Poseidon was used successfully to predict the 1997-98 El Nino event earlier than ever before. It features text, remotely-sensed imagery and a link to JPL's Physical Oceanography website.

These four lessons accompany the FARMLAND Film and dive deeper into issue discussed in the film like Animal Welfare, Farm Risk, Farm Size, and GMOs. There are also facilitated discussion questions. Students will learn about the care of livestock on farms and consider regulations and government’s role in the industry. Students will understand farm-related risk and how it relates to the risk in everyday life. Students will explore farm size in the U.S. and how farmers are able to feed a growing population. Students will gain a basic understanding of genetically engineered crops and compare conventional and organic farming practices.
