Physiology & Biomedical Engineering – Day 2
Today our students delved more into understanding the physiological aspects of the digestive system by learning about the magic of enzymes and how these special proteins are able to help us chemically digest all the different foods (and sometimes non-food items) we eat. Students were also officially introduced to the Digestion Invention project they will be working on throughout the week, which (if done successfully) will have the ability to mimic the mechanical & chemical digestion capabilities of a real, in vivo digestive system.
Fairy Tale Houses – Makey Lab
Can the houses stand up to the natural disasters? The fairy tale realm sure hopes so! Our campers finished building the new houses for the magical world, designed specifically to remain standing during specific events – earthquake, avalanche, flash flood, thunderstorm, and rock slide. The houses were tested and judged – did they hold up?
Ask your camper: Which disaster did you build a house for, what materials did you use, and did it remain standing?
Power Up! – Game Day STEM
In their second day of working on their mechanical swimmers, our engineers added a motor! Swimming requires a series of complex movements in order for the swimmer to travel through the water. In this case, the motorized system will consist of a metal wire attached to a pulley powered by a mini-motor. A metal wire will rotate creating a propulsion mechanism that moves the swimmer’s body through the water. The students will finish building the “arms” of their swimmers later this week.
Ask your camper: What are some of the physical characteristics the mechanical swimmer should have in order for it to move through the water?
Engineering Explorations – Model Heart Valve
Our body tissues are made up of cells that need oxygen to do work, and give off carbon dioxide as a byproduct. Using this knowledge, the biomedical engineers designed a model heart valve! The most difficult part of the engineering process was discovering how to make the “blood” only travel in one direction. The engineers tried lots of methods and refined their designs. The campers learned how important it is for the blood to flow in one direction!
Ask your camper: Why is it important for blood flow to be unidirectional?
