The Beat Goes On (Activity)
In this activity, students learn about their heart rate and different ways it can be measured. Students construct a simple measurement device using clay and a toothpick, and then use this device to measure their heart rate under different circumstances (i.e., sitting, standing and jumping). Students make predictions and record data on a worksheet.

"The People Were Very Peaceable": The U.S. Senate Investigates the Haitian Occupation
Largely at the behest of American bankers, U.S. marines occupied Haiti from 1915 to 1934. By 1919, Haitian Charlemagne PÃ©ralte had organized more than a thousand cacos, or armed guerrillas, to militarily oppose the marine occupation. The marines responded to the resistance with a counterinsurgency campaign that razed villages, killed thousands of Haitians, and destroyed the livelihoods of even more. The military atrocities and abuse of power during the Caco War of 1919â€“1920 led to a U.S. Sena

PediNeuroLogic Exam: Developmental Anatomy - Brain Growth
The newborn brain weighs 400 grams. At one year of age the brain weighs 1,000 grams. By 2 years of age the brain has reached 80 percent of its adult size. By 18 years of age the brain has reached its adult weight of 1400 grams. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.

PediNeuroLogic Exam: Newborn: Normal: Tone - Arm Traction
Arm traction is done with the baby in the supine position. The wrist is grasped and the arm is pulled until the shoulder is slightly off the mat. There should be some flexion maintained at the elbow. Full extension at the elbow is seen in hypotonia. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.

SeaWiFS: The Fishing Season in Central America
By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. Until now, scientists have only had a continuous record of photosynthesis on land. But following three years of continual data collected by the SeaWiFS instrument, NASA has gathered the first record of photosynthetic productivity in

Erythemal Index for August 2000 through July 2001: Rotating Globe
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the

Light Absorption, Refraction, and Reflection - by StudyJams
Light always travels in a straight line until something gets in its way.  When that happens, light can be absorbed, reflected, or refracted, depending on what kind of surface it hits.  Learn more about light with this cartoon animation from StudyJams.  A short, self-checking quiz is also included with this link.
