Sunscreen Development: Click here for final stage gate.
The main focus of this study was material science. As both engineers and environmentalists, students were tasked with not only developing a safe sunscreen formula, but also with developing an environmentally friendly packaging for the sunscreen. Using the legal limits of chemicals in sunscreen, we tested their effect on e. coli bacteria to assess its safety.

Sea Life Improvement: Click here for final stage gate
As residents of the Baltimore area, our team recognized the urgent problems that
sea life was facing in the Chesapeake Bay. One of these problems includes the
low levels of oxygen in the bay. Current efforts include oyster restoration by
placing concrete beds with recycled oyster shells in the bay, as oysters play a
vital role in removing oxygen consuming plants such as algae Our team hoped to
enhance oxygen levels by creating a biodegradable plastic tube that would
release oxygen as it degrades. To the right is the biodegradable plastic that
was made and used to form the tube. During the creation and testing of this
tube, we presented our findings to fellow STEM students in several stage gate
presentations.
