Intercept (b) of a line (Coordinate Geometry)
An interactive applet and associated web page that demonstrate the intercept (b) of a line. The applet has two points that define a line. As the user drags either point it continuously recalculates the intercept, the point where the line crosses the y-axis at x=0. Can be used in conjunction with the slope to derive the equation of a line. The grid, axis pointers and coordinates can be turned on and off. The intercept calculation can be turned off to permit class exercises and then turned back on
Horizontal line definition. (Coordinate Geometry)
An interactive applet and associated web page that show the definition of a horizontal line in coordinate geometry. The applet has two points that the user can drag which define a line. The line flagged when it is horizontal (slope=0) and the equation of the line is shown. The grid, details and coordinates can be turned on and off. The applet can be printed exactly as it appears on the screen to make handouts. The web page has a discussion on how to test for horizontal, the line equation and has
Equation of a line - point - slope form. (Coordinate Geometry)
An interactive applet and associated web page that demonstrate the equation of a line in point-slope form. The user can move a slider that controls the slope, and can drag the point that defines the line. The graph changes accordingly and equation for the line is continuously recalculated with every slider and / or point move. The grid, axis pointers and coordinates can be turned on and off. The equation display can be turned off to permit class exercises and then turned back on the verify the a
Equation of a line - slope and intercept form. (Coordinate Geometry)
An interactive applet and associated web page that demonstrate the equation of a line in coordinate geometry. The equation is in the form y=mx+b. The user can move two sliders that control a and b. The graph changes accordingly and equation for the line is continuously recalculated with every slider move. The grid, axis pointers and coordinates can be turned on and off. The equation display can be turned off to permit class exercises and then turned back on the verify the answers. The applet can
Distance between points
An interactive applet and associated web page that demonstrate how to find the distance between two points with given coordinates. The applet has two points on a Cartesian plane. As the user drags either point it continuously recalculates the distance between them. The distance is shown both on the plane and as a continuously changing formula. The grid, axis pointers and coordinates can be turned on and off. The distance calculation can be turned off to permit class exercises and then turned bac
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
Interdisciplinary Integrated Unit on DNA/Genetics Part B: Math
This lesson is part of an interdisciplinary integrated unit on DNA and genetics. The idea is for students to complete a week's worth of activities in science, math, and language arts. This lesson is Part B: Math. Students will complete a math survey interviewing people on whether they believe humans should or should not be cloned. They will take the data they gather and create computer generated spreadsheets, charts/graphs. Using the charts/graphs, students will answer mathematical percent and r
Digital Storytelling in the Classroom and Beyond
This workshop explores how contemporary technology tools empower students and teachers to engage in highly creative and reflective tasks to organize and present information, and express emotions, ideas and knowledge through multimedia creations known as digital stories. Digital storytelling is increasingly becoming popular in schools all over the world as an engaging technology-based learning strategy. In this workshop, the participants will be exposed to powerful user-friendly and cost-free tec
HOU Middle School Curriculum: Solar System Science
The HOU Middle School Curriculum, Solar System Science (previously Hands-On Solar System or HOSS), lets your students use images from professional telescopes along with image processing software developed for use in the classroom, to learn key concepts in astronomy, mathematics, and technology. Solar System Science blends content learning with critical thinking skills and processes such as data interpretation, measurement techniques, and using appropriate tools for exploration.

River City Project
As visitors to River City, students travel back in time, bringing their 21st century skills and technology to address 19th century problems. With funding from the National Science Foundation, we have developed an interactive computer simulation for middle grades science students to learn scientific inquiry and 21st century skills. River City has the look and feel of a video game but contains content developed from National Science Education Standards, National Educational Technology Standards, a
Peer-to-Peer Copying
Most Internet content today is "served" from a central system that takes requests from a user's "client." Typically, the user asks for access to information or other data; the requested content is then "pushed" from the central system to the user. In this model, the various visitors to a given web site do not interact. By contrast, peer-to-peer technology (commonly known as "P2P") creates conversations among individual personal computers (PCs). In this respect, P2P systems resemble an affili
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

Access to the Internet
Using the Internet depends, in the first instance, on access to the network. The initial emergence of "the Internet" in the early 1990s, from the increasing connectivity of a series of university and government networks alongside private services like America Online, Prodigy, and CompuServe, occurred almost entirely across slow dial-up modem connections over telephone wires. Sufficient for email, Usenet news groups, transferring relatively small files, and later viewing simple web pages, slow tr
The Law of the Internet
The Internet is at once a constructive and disruptive technology. As more and more of our lives move online, we are faced with opportunities to do new and amazing things. Concurrently, we encounter problems that no one anticipated as we collectively built the internet as we know it today. This seminar will consider some of the most intriguing of the issues to which the advent of the internet has given and continues to give rise. It will focus on a cluster of topics about which any computer user
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
Elementary GLOBE: Earth System Play
The class will brainstorm, write, create, and produce a play in which they represent how all the Earth systems are interconnected. This play can be based on the Elementary GLOBE book "All About Earth: Our World on Stage" or on other student-generated topics representing interconnections of the Earth systems. The purpose of the play is to serve as a performance assessment providing students with the opportunity to display what they have learned about the Earth as a system in a creative manner. Th
