When a pair of scientists first introduced cold nuclear fusion in 1989 as a source of almost limitless energy, the scientific community quickly discredited the experiments. In some venues, these experiments are case studies in faulty scientific investigation. But now a respected scientist at SRI International is doing extensive research on the same process -- with promising results. This 12-minute investigative report by CBS <i>60 Minutes</i> explores the renewed interest in cold fusion and its implications for society. <i>This resource is available for free online viewing. A four-page text synopsis is also provided. It could be especially useful as a springboard for a lesson on the importance of objectivity in scientific experimentation.</i>

The Acid Strong Base Titrations model show how to estimate the concentration of the acid in a given sample. If one follows the titration by a visual indicator, the neutralization is detected through a sudden change of that indicator color. This model shows the titration curve as a strong monofunctional base (sodium hydroxide, for example), is added to an aqueous solution of a monoprotic acid. The Acid Strong Base Titrations model was developed using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the jar file will run the program if Java is installed. You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.

The book, Sorbjan, Z (1996):Hands-on Meteorology, published by the American Meteorological Society, is an excellent source of ideas for teachers to use in the classroom. However, no book can be complete, so this web site is an extension of the ideas in Sorbjan's very readable book. The project grew out of a number activities which were originally documented in Neuberger, Hans and George Nicholas (1962):Manual of Lecture Demonstrations, Laboratory Experiments, and Observational Equipment for Teaching Elementary Meteorology in Schools and Colleges, College of Mineral Industries, The Pennsylvania State University, University Park, PA, 183 pgs. The original activities were constructed, documented and tested in three summer workshops; however, there were some errors and misleading concepts presented. These have been corrected.Since the time the Manual was written, there have been some major changes in education as well as the technology available in the classroom. The author has added a significant number of activities to the original manual, including two laboratory exercises used in Meteorology 101 at Montgomery College, Germantown. My thanks to a summer Intern, Joshua Larson, who did much of the scanning and initial drafting of the work.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated. The inflated ball has the greater mass so learners can conclude that gas is matter because it has mass and takes up space. Then learners consider how heating and cooling affect molecular motion in gases. They dip the mouth of a bottle in detergent solution and observe a bubble growing and shrinking when the bottle is warmed and cooled. Learners will discover that the attractions between gas molecules are so minimal that attractions canäóťt be used to explain the behavior of gases like they can for liquids and solids.

The Airborne Infection SEIR Model examines the time evolution of four populations in an epidemic: those who are susceptible to infection, those who have been exposed but do not yet exhibit symptoms, those who are infected and contagious, and those who have recovered from the infection. The SUSCEPTIBLE-EXPOSED-INFECTED-REMOVED (SEIR) Model shows that infection can spread throughout a population in just a matter of days. Infections and viruses can be transmitted relatively easily, or can be prevented all together if certain conditions are satisfied. This model examines the spread of infection in indoor environments and the parameters that shape its transmission. The Airborne Infection SEIR Model was developed using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the jar file will run the program if Java is installed. You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.
