Title: Engineering a bridge using spaghettis to teach about balanced/unbalanced forces (4th grade)
In this workshop you will work in small teams to build a bridge using spaghettis and test it using different masses. We will explain how the building structure is affected by forces using science concepts (balanced/unbalanced forces). In addition, we will connect this engineering activity to children’s literature for the engage section. more »« less

Abstract Embryonic morphogenesis is a biological process which depicts shape forming of tissues and organs during development. Unveiling the roles of mechanical forces generated, transmitted, and regulated in cells and tissues through these processes is key to understanding the biophysical mechanisms governing morphogenesis. To this end, it is imperative to measure, simulate, and predict the regulation and control of these mechanical forces during morphogenesis. This article aims to provide a comprehensive review of the recent advances on mechanical properties of cells and tissues, generation of mechanical forces in cells and tissues, the transmission processes of these generated forces during cells and tissues, the tools and methods used to measure and predict these mechanical forces in vivo, in vitro, or in silico, and to better understand the corresponding regulation and control of generated forces. Understanding the biomechanics and mechanobiology of morphogenesis will not only shed light on the fundamental physical mechanisms underlying these concerted biological processes during normal development, but also uncover new information that will benefit biomedical research in preventing and treating congenital defects or tissue engineering and regeneration.

We have developed a microfluidic platform for engineering cardiac microtissues in highly-controlled microenvironments. The platform is fabricated using direct laser writing (DLW) lithography and soft lithography, and contains four separate devices. Each individual device houses a cardiac microtissue and is equipped with an integrated strain actuator and a force sensor. Application of external pressure waves to the platform results in controllable time-dependent forces on the microtissues. Conversely, oscillatory forces generated by the microtissues are transduced into measurable electrical outputs. We demonstrate the capabilities of this platform by studying the response of cardiac microtissues derived from human induced pluripotent stem cells (hiPSC) under prescribed mechanical loading and pacing. This platform will be used for fundamental studies and drug screening on cardiac microtissues.

In this workshop, we show activities developed and implemented as part of a National Science Foundation project (Award #2121351) based on how to use a modified engineering model to teach about the properties of sound in elementary grades. We cover 4th grade physical science related to forces (Georgia standard, S4P2; NGSS standard 4-PS4-1) and the cross cutting concept of cause and effect. Using translanguaging practices and technology, participants will learn about a modified 7-step engineering method and will participate in building a small guitar. This activity is highly engaging for students and a very effective approach to teach the engineering design process.
