Physiology & Biomedical Engineering – Day 3
A full work day was in store for our students today as they used the bulk of their class period to continue designing & engineering their Digestion Invention project. Students were also able to conduct some of their first preliminary test runs with their projects to ensure that all the different parts of their system are well-connected and that the GI tract is leak-proof.
Engineering Explorations – Parallel and Series Circuits
Today, campers explored the difference between a basic (single-load) circuit and more complex circuits in series and parallel (with 2+ loads) using tape circuit templates! They discovered that series circuits may not be as efficient as parallel circuits and were challenged to create multi-load circuit paths with copper tape, coin batteries and LED lights.
Ask your camper: What is voltage drop? (in a series amount of voltage decreases after each load; in our case the LED lights further along the circuit path weren’t as bright)
Makey Lab – Merry-go-rounds
The playground engineers of the local school have asked for our help! They lost the plans to all of the new playground equipment and it’s the job of our young engineers to design and build a new merry-go-round. Along the way the campers learned about centripetal force, which is the force needed to make something move in a circle. After building their merry prototypes, the campers tested their designs with differently massed objects.
Ask your camper: What is centripetal force?
A Motion Picture – Game Day STEM
How is motion represented as a distance-time graph? Today, campers used specialized motion-detecting equipment (called a Calculator-Based Ranger, or CBR) which connects to a graphing calculator and provides a graphical display of detected movements. Campers were challenged to do certain maneuvers and examine the graphical displays to begin to make sense of graphical displays of the movements.
Ask your camper: What does the graph of a person jumping on a trampoline look like? (an arc)
