Smart Move!
This is a simple activity to visualize a communication system. In order to do this the students encode, decode, transmit, receive and store messages. They will use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve information as and when it is required.
Forces and Graphing
This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students learn how to conduct an experiment by applying loads at different locations along the beam, recording the exact position of the applied load and the reaction forces measured by the scales at each end of the beam. In addition, students will analyze the experiment d
The Strongest Pump of All
In this lesson the students will learn how the heart functions. Students will be introduced to the concept of action potential generation. The lesson will explain how action potential generation causes the electrical current that causes muscle contraction in the heart. Students will be introduced to the basic electrical signal generated by the heart; P, QRS, and T waves. The lesson will approach the heart from an engineering standpoint and encourage students to design ways to improve heart funct
Levers that Lift
This lesson introduces students to three of the six simple machines used by many engineers: the lever, the pulley, and the wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines helps determine their ability to make work easier or make work faster.
Multiple Sclerosis - Coordination Exam - Lower Extremities Sub-exam - Patient 18
Ed is a 57-year-old Caucasian male with a 15-year history of neurological disability that was diagnosed after his initial attack as multiple sclerosis. Lumbar puncture demonstrated the presence of numerous oligoclonal bands and MRI later showed multiple white matter plaques. He suffers from a significant dysarthria, as well as tremor and ataxia.
Parkinson Disease - Cranial Nerves Exam - Oculomotor, Trochlear, Abducens (CN III, IV, VI) Nerves Su
This 76-year-old man developed tremor of his right arm and leg 15 years ago. It has increased in severity over the years. A shaking right hand affects his writing, dressing and drinking. Occasional drooling, difficulty rolling over in bed and a soft voice at times are also issues. The tremor has affected his writing and he has mild difficulty with buttons and zippers. He spills when he uses his right hand to drink. He has occasional drooling and slight difficulty rolling over in bed. His voice
Neuropathy - Motor Exam - Screening Tests Sub-exam - Patient 7
This 61-year-old man has had slowly progressive gait disturbance and weakness of his legs for 14 years. He has developed a limp in both legs, and his feet trip on objects and on uneven floor surfaces resulting in falls. He feels uncoordinated and unbalanced especially in the dark. He has to use a cane to assist ambulation. For the last 10 years, he has had numbness and tingling in both lower extremities. This began in his toes and now has extended proximally to his knees.
Posterior Fossa Tumor - General Observations Exam - Opening Interview 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. Patient reports an increase in balance problems while standing over the past 4 months. He has noticed that he staggers a step or t

Ferns attached to a forest rock
Ferns have small, branched leaves, not to reduce gas exchange and water loss, but to increase the surface area for spore producing structures. This demonstrates that plants develop certain characteristics for very different reasons.

Rocket Car on an Inclined Plane Model
The EJS Rocket Car on an Inclined Plane model displays a car on an inclined plane. When the car reaches the bottom of the incline, it can be set to bounce (elastic collision) with the stop attached to the bottom of the incline. The car consists of the car body, two rotating front wheels, and two rotating rear wheels. The incline angle (in radians) can be changed via a textbox and the rocket’s thrust can be changed via a slider. In addition the car can be dragged to its initial position. A
