Op het einde van deze les kun je inhoudelijke vragen over een tekst over de regionale specialiteiten van Yorkshire beantwoorden.
Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each other in a specific pattern, making a double helix. They investigate specific DNA sequences that code for certain physical characteristics such as eye and hair color. Student teams trade DNA "strands" and de-code the genetic sequences to determine the physical char
In this activity, students investigate how sound travels through both string and air. First, they analyze the sound waves with a paper cup attached to a string. Then, they combine the string and cup with a partner to model a string telephone. Finally, they are given a design scenario to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the telephone has had on society.

"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. Like hundreds of other campuses across the country, Kent State witnessed an upsurge in student activism following the American invasion of Cambodia in 1970. The Guardsmen arrived when students burned down the Reserve Officers Training Corps (ROTC) building, and Vacarella remembered that their arrival was met with hostility – along with thrown rocks and bottles – from angered students. Two
"In the Shadow of Society": Migrant Workers and Unionists Urge Congress to Enact Effective Federal F
In the early 20th century, large-scale commercial agriculture displaced family farms, tenant farmers, and sharecroppers. Hand labor, however, remained more cost effective for harvesting certain fruits and vegetables. Farmworkers under this new system were hired only for seasonal work and had to travel frequently. The migratory experience left these workers--primarily Mexicans, Mexican Americans, African Americans, Puerto Ricans, and Filipinos÷permanent outsiders and vulnerable to exploitation,
The Bracero Program
The government-sponsored Bracero Program was the temporary importation of workers from Mexico to aid the American agricultural economy. This was an important historical event that many Americans are unaware of today. A bracero (from brazo, the Spanish word for arm) was a Mexican worker allowed entry into the United States for a limited time, usually to work on a farm. 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

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
