    The problem of retrieving and storing core samples from a hole drilled on the lunar surface is addressed. The total depth of the hole in question is 50 meters with a maximum diameter of 100 millimeters. The core sample itself has a diameter of 60 millimeters and will be two meters in length. It is therefore necessary to retrieve and store 25 core samples per hole. The design utilizes a control system that will stop the mechanism at a certain depth, a cam-linkage system that will fracture the core, and a storage system that will save and catalogue the cores to be extracted. The Rod Changer and Storage Design Group will provide the necessary tooling to get into the hole as well as to the core. The mechanical design for the cam-linkage system as well as the conceptual design of the storage device are described

    Since the islands fell under British rule, the British Virgin Islands High School has invoked strict education standards. Consequently, the curriculum prohibits creativity, does not properly accommodate learning handicaps, and does not provide students with a suitable technological background. Through interviews, investigations and pupil-teaching, this project has addressed all of these problems mentioned as well [as] developed a textbook that will modernize teaching in the British Virgin Islands High School. The investigation into the school's curriculum were made through test assessments, pupil interaction with technologies, including computer hardware and software, and calculators. Working with students in and out of the academic environment helped us to adapt to the customs of the island. All of these allowed us to properly assess the dynamics of the school, as well as the motivation of the teachers and students. Recommendations were made based on teachers' opinions as well as these assessments
