Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn about volume, buoyancy and density to help them iterate more successful balloon designs.Applying their newfound knowledge, the young engineers build and test balloons that fly carrying small flip cameras that capture aerial images of their school. Students use the aerial footage to draw maps and estimate areas.

Students explore static electricity by rubbing a simulated balloon on a sweater. As they view the charges in the sweater, balloon, and adjacent wall, they gain an understanding of charge transfer. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments.

The purpose of this activity is to bring together the students' knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure whereby one variable is changed and all the others are kept constant.
Students groups use balsa wood and glue to build their own towers …
Students groups use balsa wood and glue to build their own towers using some of the techniques they learned from the associated lesson. While general guidelines are provided, give students freedom with their designs and encourage them to implement what they have learned about structural engineering. The winning team design is the tower with the highest strength-to-weight ratio.

The purpose of this task is to provide students with a multi-step problem involving volume and to give them a chance to discuss the difference between exact calculations and their meaning in a context.

This task asks students to use similarity to solve a problem in a context that will be familiar to many, though most students are accustomed to using intuition rather than geometric reasoning to set up the shot.
This is the third edition of Bankruptcy Law and Practice, a Casebook …
This is the third edition of Bankruptcy Law and Practice, a Casebook Designed to Train Lawyers for the Practice of Bankruptcy Law. It is designed for a one-semester course in debtor/creditor law and bankruptcy. The book deals with both creditor remedies and debtor protections, starting with state law collection remedies, exemptions, and the important special protections for secured creditors under both Article 9 of the Uniform Commercial Code and state real property recording acts. After a thorough review of state law debt collection practice, the book covers the basics of straight bankruptcy law with a focus on Chapter 7 of the Bankruptcy Code, both for individuals and businesses. Although the book has a practice focus, it covers the major Supreme Court cases, and important appellate cases with an emphasis on areas of uncertainty. The book also emphasizes the Bankruptcy Code itself, using problem sets to get students to work through the language of the Bankruptcy Code.
At the end of the book are two abbreviated chapters on bankruptcy reorganizations for consumers under Chapter 13 and for businesses under Chapter 11. These chapters are intended to outline the reasons that debtors choose to file for reorganization rather than liquidation, and focuses on the rules for confirming a plan.
The primary goal of the book is to prepare students for the practice of bankruptcy law. Students who understand these materials should be well prepared to anticipate and address the kinds of issues that arise in real bankruptcy cases, whether in a small dollar consumer practice or a big dollar corporate reorganization. Students will learn the language of commercial law and bankruptcy, along with the skills to find their way around the Bankruptcy Code.
This is a true digital book, with links to both the cases and the statutes. The case links jump to the full text in the free Google Scholar website, while the statutory links jump to reprinted statutes in the appendixes of the book. No materials other than the book are needed.

This task could be put to good use in an instructional sequence designed to develop knowledge related to students' understanding of linear functions in contexts. Though students could work independently on the task, collaboration with peers is more likely to result in the exploration of a range of interpretations.
This free online textbook is a one semester course in basic analysis. …
This free online textbook is a one semester course in basic analysis. These were my lecture notes for teaching Math 444 at the University of Illinois at Urbana-Champaign (UIUC) in fall 2009. The course is a first course in mathematical analysis aimed at students who do not necessarily wish to continue a graduate study in mathematics. A Sample Darboux sums prerequisite for the course is a basic proof course. The course does not cover topics such as metric spaces, which a more advanced course would. It should be possible to use these notes for a beginning of a more advanced course, but further material should be added.

A grasp of the logic and practice of science is essential to understand the rest of the world around us. To that end, the CMB3e iText (like earlier editions) remains focused on experimental support for what we know about cell and molecular biology, and on showing students the relationship of cell structure and function. Rather than trying to be a comprehensive reference book, CMB3e selectively details investigative questions, methods and experiments that lead to our understanding of cell biology. This focus is nowhere more obvious than in the chapter learning objectives and in external links to supplementary material. The Basic CMB3e version of the iText includes links to external web-sources as well as the author’s short, just-in-time YouTube VOPs (with edited, optional closed captions), all embedded in or near relevant text. Each video is identified with a descriptive title and video play and QR bar codes.
