Posterior Fossa Tumor - Cranial Nerves Exam - Vestibulocochlear (CN VIII) Nerve Sub-exam - Patient 9
Patient is a 58-year-old white male with a history of acoustic neuroma that was resected in 1990. He has residual cranial nerve palsies on the right side and experiences tremors, ataxia and disequilibrium. His wife reports that she has noticed an increase in right hand tremor for the past year or so. The tremor worsens as the day progresses and occurs with activity.

For the last 10 years, he has consumed a quart of vodka and 5 beers daily. On awakening, he feels "shaky" and calms himself with a morning drink. He has not had blackouts or
Primary Lateral Sclerosis - Motor Exam - Muscle Strength Sub-exam - Patient 14
This video features a 54-year-old white male who presented for evaluation of progressive spastic paraparesis. He stated that symptoms first started in 1997 when "things were different with my legs" (i.e., leg weakness, imbalance, and speech problems). Symptoms started in his left foot, when he couldn't keep time to music. His feet started dragging and he also noticed problems with balance. In 1999, he started falling and sought medical attention.

Spastic Paraplegia - Cranial Nerves Exam - Oculomotor, Trochlear, and Abducens (CN III, IV, VI) Sub-
This video features a 54-year-old white male with a history of spastic paraplegia (diagnosed in 1994) and no previous history of heart disease or cardiac workup. He presented to the Emergency Room complaining of three days on-and-off retrosternal chest pain. Patient presented to the ER complaining of three days on-and-off retrosternal chest pain, rated 3/10, lasting approximately 30 minutes, occurring multiple times daily at rest or during activity. The first episode occurred three days before
Time-light and shadow (pre-visit)
Students examine the interplay of the earth and the sun by studying shadows. Students construct a sun clock and record shadows several times during a school day in order to use the earth and the sun to measure time.
Modern Day Pyramids
Students investigate the ways in which ancient technologies six types of simple machines and combinations are used to construct modern buildings. As they work together to solve a design problem (designing and building a modern structure), they brainstorm ideas, decide on a design, and submit it to a design review before acquiring materials to create it (in this case, a mural depicting it). Emphasis is placed on cooperative, creative teamwork and the steps of the engineering design process.
Introduction to VEF
The Vietnam Education Foundation (VEF) is an independent federal agency created by the U.S. Congress and funded annually by the U.S. Government. Its mission is to strengthen the U.S.-Vietnam bilateral relationship through educational exchanges in science and technology. VEF is governed by a Board of Directors including U.S. Cabinet Members, U.S. Senators and Representatives and Presidential Appointees. VEF headquarters is located in the Washington D.C. area, with a representative office in Hanoi
Written Mentalities from the course History of Information
This course explores the history of information and associated technologies, uncovering why we think of ours as 'the information age.' We will select moments in the evolution of production, recording, and storage from the earliest writing systems to the world of Short Message Service (SMS) and blogs. In every instance, we'll be concerned with both what and when and how and why, and we will keep returning to the question of technological determinism: how do technological developments affect socie

Into Space!
This activity introduces students to the basic physics concepts on how rockets work through the building and testing of a model rocket fueled by an antacid. Students have the opportunity to revise and improve their initial design. Note: This activity is similar to film canister rockets that students make in elementary school but is adapted for middle school.
Our Amazing, Powerful Sun
The purpose of this lesson is to introduce the students to the Sun. They explore various aspects of the Sun including its composition, its interior workings, and its relationship to the Earth.
Messin' with Mixtures
In this activity, students investigate the properties of a heterogeneous mixture, trail mix, as if it were a contaminated soil sample near a construction site. This activity shows students that heterogeneous mixtures can be separated by physical means, and that when separated, all the parts will equal the whole.
2.1 Some basic concepts
Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth. Is nuclear power a salvation or a nightmare? This unit provides background information to each resource, so that you can assess them for yourself.
