What happens when you shoot a ping-pong ball at speeds faster than an F16 fighter jet can fly? Take a look for yourself. Kind of makes me wish I had majored in Mechanical Engineering. Here is a link to the Perdue web page.
The Cardiac Conduction System Sino-Atrial [SA] node or primary pacemaker – cells that generate an electrical current. Atrioventricular [AV] node or secondary pacemaker- receives the electrical impulse. Cardiac muscle action potentials– SA-AV electrical activity causes the right atrium to contract. Heartbeat -the result of cardiac muscle action potential, travelling throughout the heart. Intrinsic heart rate: […]
This summer Valencia is going to host a STEM camp for high school seniors, and we are going to have 24 students visiting different science labs at West Campus during two days. I may use some portion of this “sample lesson” for the physics portion of the STEM camp. I will start with projecting a […]
