2018 MRET Program
MRET Host Labs, Summer 2018
Jennifer Andrew (Materials Science & Eng.), Mentors: Prabal Tiwari and Amanda Uhl
This project will focus on the development on enzymatically degradable hydrogels that automatically dissolve in the body that can be used for the treatment and detection of lung diseases. The teacher participants will learn how to make and characterize the materials using basic chemistry techniques.
Christine Angelini (Environmental Eng.), Mentors: Julie Walker and Kimberly Prince
This project will investigate the effects of burrowing crabs on below-ground root production, decomposition processes and carbon stocks at the salt marsh- mangrove ecotone on both the east and west coast of Florida. The RET teachers will join the grad students in the field for sampling of field experiments as well as process soil cores in the lab.
Thomas Angelini (Mechanical & Aerospace Eng.), Mentors: Marcus Garcia and Tristan Hormel
Epithelial tissues throughout the body produce mucus layers containing large proteins called mucins. These mucus layers are generally thought to lubricate the diverse epithelial surfaces in the body, including the eye and the gut. In this project, we will study different types of epithelial cells which produce different amounts of mucus, and we will use enzymes to degrade robust mucus layers. Teachers will help care for cells and analyze microscope images of experiments.
Yong Huang (Mechanical & Aerospace Eng.), Mentors: Yifei Jin and Kaidong Song
For engineered constructs like heart tissue to repair a heart attack to be viable, they must have vascular trees to supply nutrients and oxygen. This project aims to explore a novel three-dimensional printing technique to fabricate tissue constructs embedded with vascular trees and further evaluate their biological functionality in a perfusion bioreactor. Teachers will help build and test engineered tissues using biology and chemistry techniques
Tanmay Lele (Chemical Eng.), Mentors: Julie Jameson and Andrew Tamashunas
Cells in our body perform complex tasks, including movement across tissues, adhesion to proteins in the body, and the sensing of chemical and mechanical signals. These complex processes depend in large part on the “skeleton” inside the cell called the intracellular cytoskeleton. We are interested in how the cytoskeleton and associated proteins generate forces inside the living cell. This work can help us understand diseases of the cardiovascular and muscular system as well as cancer. Teachers will learn how to care for cells, perform biology experiments, and take images on the microscope.
Eric McLamore (Agricultural & Biological Eng.), Mentors: Victoria Morgan and Nicolas Cavallaro
This research group focuses on development and application of sensor/biosensor technology for solving hypothesis driven research questions in the life sciences. We build optical and electrochemical tools from the nanometer to the millimeter spatial scale, often incorporating biological molecules as an active element (i.e., biosensors). We commonly use a non-invasive technique known as self-referencing, which allows us to measure the transport of molecules across cell membranes and/or tissues. We also build sensors for field applications used in environmental and agricultural research.
Chelsey Simmons (Mechanical & Aerospace Eng.), Mentors: Dan Stewart and Myra Kurosu Jalil
While many amphibians can regrow entire limbs and organs, mammalian regeneration is essentially unheard of in the natural world. Recently, we have identified a remarkable mammal that has regenerative ability – the African Spiny Mouse (Acomys). With the Acomys model and our innovative suite of tunable mechanical microenvironments, we are working to understand the role of mechanical stretching, if any, in scar-free wound healing. Teachers will be trained in cell biology, materials science, and mechanical testing methods while in the lab.

Students will also be engaged in the engineering design process as they conduct research, collaborate, use their senses to make observations, and collect and record data. This cross-curricular unit allow students to be creative, problem solve, and learn to care for our Earth!
Meagan Vaughn (2018) Finley Elementary School 2nd Grade
Are your students’ classroom supplies all over the place? Let nature help get your class organized in this fun beginning of the year unit on biomimicry! In this STEM unit, students will learn how engineers use nature to solve problems by studying two of nature’s smallest organizers – ants and bees. Students will use their learning to brainstorm, collaborate, create, and test a tabletop organizer of their designing. Over the course of two weeks, students will learn through the engineering design process that they can solve problems! Science, math, language arts, and engineering approximations make this unit an engaging and rigorous addition to your curriculum.
Engineering a Marshmallow Catapult: Ready, Set, Launch Those Marshmallows!
Lynda Harris (2018) Finley Elementary School 3rd Grade
This engineering unit covers science, math, and ELA skills. Based on the book The Marshmallow Incident, students will work together, learn the engineering design process and create a catapult that can launch a marshmallow at a given distance. This unit is more challenging based on the approximations and constraints that each group must overcome. Students will experience failure, but that is a part of the learning process.
Sarah Hersey (2018) Williams Elementary School 3rd Grade
In this unit, students will be introduced to engineering and complete a partial design process. Your students will be presented with an authentic problem: the importance of collecting specimens from the field necessitates effective and humane tools to do so. Working in groups and independently, students will apply their knowledge of engineering design to create the best minnow trap. Multiple trials and troubleshooting are emphasized in this unit as approximations of true design.
Sea Turtle Engineering
Mackenzie McNickle (2018) Foster Elementary School 3rd Grade
Did you know that Hurricane Irma wiped out nearly half of all sea turtle nests in Florida? Only one out of every one thousand eggs make it to adulthood! In this unit, students studied sea turtles and their nesting behavior, and then developed a solution to the problem by building a structure to fit over nests. After testing their structures in a “hurricane simulator,” they took on the role of social activists by preparing collaborative Google Slides presentations in which they plead their case to concerned stakeholders.
Engineering a Habitat’s Humidity
Kayla Sutcliffe (2018) Glen Springs Elementary 3rd Grade
This is an engineering unit that covers ELA, math, and science standards in which students will be designing an optimal temporary habitat for a future classroom pet, a hingeback tortoise. Based on background research conducted and their knowledge of condensation, students will identify what humidity level the tortoise needs, as well as what its habitat is like. Each group will research, brainstorm, collect and analyze data, and design their final plan. They will then communicate and present this information to the rest of the class.
There’s Still Time
Lisa Williams (2018) Foster Elementary School 3-5 Media
What will happen if Florida loses its state animal to extinction? I do not want to imagine that, would you? In this activity, students researched the endangered Florida Panther and its habitat in search of a solution of the factors that make the Florida Panther endangered of becoming extinct by automobiles and the loss of habitat. Students learned and applied the steps of the Engineering Design Plan in sequential order as they sought a solution to help save the Florida Panther. Once data was gathered and students understood these factors, students independently played around with possible solutions by experimenting with 3D objects such as blocks and Legos. After brainstorming in teams, students built a prototype of the team’s best solution using 3D Doodler pens.
