"It Couldn't Go On Like This:" Jim Vacarella Describes Events Leading Up to the Kent State Shootings
Jim Vacarella was a student at Kent State University when the National Guard arrived on campus in 1970.

In 1942, facing an extreme shortage of farm labor workers due to the war, Congress enacted the Emergency Labor Program. It approv
Pathophysiology of Infectious Diseases
Medical Microbiology is a vast and ever expanding complex field. The role of microbes in chronic illness, like coronary disease and arthritis, continues to evolve. For example, in the Emerging Infections and Agents of Biological Warfare Lecture, one will learn that while advances in identification, culture techniques, diagnosis and treatment have led to remarkable improvements in the consequences of infectious diseases worldwide in the past quarter century, newly identified pathogens continue to
How to Properly Strike a Xylophone
This video will teach you how to properly strike your xylophone with a mallet.
Anole lizards are reptiles because they are covered in scales. These scales are used as protection for the lizard and help the lizard retain water in its body.
In this video from Outdoor Nevada, learn about the habitat, diet, and defense mechanisms of horned lizards.
5th Grade Students and Idioms
My 5th grade class produced some idioms. We were learning about figurative language and saw some videos on them and then made our own. Lots of fun!
Multiple Sclerosis - Reflexes Exam - Abnormal (Pathological) Sub-exam - Patient 20
Janie is a 39-year-old Caucasian female who initially presented with weakness and L'Hermitte’s phenomena at the age of 35. Initially mistaken as a TIA, MRI of the brain revealed numerous plaques in the white matter suggesting Multiple Sclerosis. Her lumbar puncture initially failed to demonstrate the presence of oligoclonal bands, but since progression of the disease over the past few years bands have developed.
Life in the City
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a close-up look at biodiversity in a city park. The site opens by telling kids that, despite appearances, a great deal of biodiversity exists in cities. That from tiny mites to mighty trees, thousands of species thrive there. It then takes them to a slice of life from a thriving city park, where they are asked to find 10 hidden critters living alongside the trees, plant
Space Week: Mars Underground, Part 1
Is man's fate tied to the Red Planet? Scientists debate the future of space exploration.
SIP with SOAP
This video presents Session Initiation Protocol and its usage in the Next Generation Grid to support user-, device- and session-mobility for accessing web services.
This OLogy activity gives kids a chance to test their investigation skills while learning about daily life for the Incas. Inca Investigation begins with an introduction to archaeologist Craig Morris and the ancient Inca city that his team excavated in the Andes mountains. Then kids are given detailed directions for how to play Inca Investigation, which includes tips to help them better examine evidence. At any time, they can get help, learn how to read a plan, or browse a book about Inca history
Don't Crack Humpty
Student groups are provided with a generic car base. The groups then design a device/enclosure that will protect an egg on or in the car as it is rolled down a ramp at increasing slopes. Students will be expected to perform basic mathematical calculations using their data.

Wasting Energy at Home
People use energy in all aspects of their lives for cooking, lighting and entertainment. Much of this energy use takes place in buildings, such as our homes. To save money and reduce the impact on our environment, many people are reducing their energy use. One way is to hire engineers to perform home energy audits to understand the ways we use energy and identify ways we can conserve energy. In this activity, students act as energy conservation engineers and identify the ways energy is conserved
