Global Development Policies and Social Injustice
The Sixth Goal of the Millennium Development Goals (MDG) is: Combat HIV/AIDS, malaria and other diseases such as tuberculosis. In Bolivia, a country with a population of over 8,000,000 people, it was claimed in 2006 that there were 2366 confirmed cases of HIV. According to the World Health Organization, Bolivia is considered to be a country with a low incidence of the virus affecting 0.10% of the adult population. In contrast, it has been estimated that 50% of the population is infected
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
Physics: Light and Matter Series (CA Textbook)
This series of six books is intended for a one-year introductory course of the type typically taken by biology majors. Algebra and trig are used, and there are optional calculus-based sections. This digital textbook was reviewed for its alignment with the content standards only; California’s Social Content Review criteria were not applied. Districts, schools, and individuals planning to take advantage of this free textbook are reminded to conduct their own review to determine whether this res
Though it brings us many benefits, the march of technology makes an encompassing surveillance network seem almost inevitable, and radically changes our expectations of privacy. We owe many of the expectations of privacy we used to enjoy to a combination of immature technology and insufficient manpower to monitor us. But these protective inefficiencies are giving way to technologies of data processing and digital surveillance that will change our beliefs about privacy. We are widely tracked by pu
Internet and Society: The Technologies and Politics of Control (2003)
This course examines current legal, political, and technical struggles for control/ownership of the global Internet and its content. The course will draw upon a growing body of cyberlaw cases and commentary, class members' research, and participation by invited guests, including lobbyists, politicians, journalists, and scholars from the HLS faculty and elsewhere. Course themes include the interaction between emerging Internet self-governance regimes and rule by traditional sovereigns; the expres
Tropospheric Ozone and Smoke from Earth Probe TOMS: Indonesia
Researchers have discovered that smoke and smog move in different ways through the atmosphere. A series of unusual events several years ago created a blanket of pollution over the Indian Ocean. In this animation, significant smog or tropospheric ozone is represented by red and green and regions of significant smoke index are in shades of white and gray.
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: The Colors of the Seasons
Using a color chart, students will make observations outside during each of the four seasons. During each session, they will try to find as many colors as possible and record what they see. As a class, they will make charts describing the colors they find in each season. At the end of the school year, students will compare their results and generate conclusions about variations in colors in nature both within a season and between different seasons. The purpose of this activity is to provide the
Elementary GLOBE: All Year Long
Each student will keep a science journal during each of the four seasons. Students will record observations of the general outdoor environment they visit and then will make observations of one specific item from the habitat in each season. At the end of the school year, students will make comparisons of their seasonal drawings and share the results with the class. The purpose of the activity is to introduce students to the concept of using a science journal to record information, to have student
CK-12 Biology (CA Textbook)
As a teacher, have you ever felt that your textbook was not thorough or up-to-date? Do you have to use other resources, such as on-line resources, to teach your lessons? As a student, do you believe you can get current information from sources such as the internet rather than your textbook? The answer to these questions is usually a resounding yes. So what do school districts do? They spend millions of dollars every year to buy “current,” “up-to-date” textbooks. CK12 believes we can do
Immune Attacks content is geared for senior level high school biology and first year university biology. To play the game, users control a microscopic robot and navigate through a first-person 3D body, completing a series of stepwise missions to detect a bacterial infection and activate the appropriate defensive immune cells. These stepwise missions follow the actual biological process that occurs during an infection and how immune cells are stimulated to kill the bacteria.
Earth Exploration Toolbook Chapter: Analyzing the Antarctic Ozone Hole
Users download and analyze satellite images showing the amount of ozone in the stratosphere. They interpret the images to identify the ozone "hole" that develops over Antarctica each summer, and compare its size from year to year. Using freely available image analysis software, ImageJ, users quantify the area of the Antarctic ozone hole each October from 1996 to 2004. Finally, they bring their measurements into a spreadsheet program and create a graph to document changes in the size of the ozone
Earth Exploration Toolbook Chapter: Investigating the Precipitation-Streamflow Relationship
This activity prepares you to launch an investigation of the relationship between precipitation and streamflow for a local watershed. It can enrich a study of the water cycle. Following the step-by-step instructions in a case study you will locate, download, format, and finally graph one year of Web-based data for these two variables. The graph highlights the details of this often complex precipitation-streamflow relationship and provides a context for launching a classroom discussion of the bal
TOXMAP is a Geographic Information System (GIS) from the National Library of Medicine that uses maps of the United States to help users visually explore data from the EPA's Toxics Release Inventory. TOXMAP maps show where reported chemicals are released on-site into the air, water, and ground. The maps also identify the releasing facilities, single year releases, and chemical release trends over time.
