Three(3) Biology Laboratories
Two(2) Chemistry Laboratories
Two (2) Physics Laboratories
PATNERING/FUNDING ORGANISATION:     QUEEN’S COLLEGE OLD STUDENTS ASSOCIATION
DESIRED START DATE:                     IMMEDIATELY
TIME FRAME FOR COMPLETION OF ASSIGNMENT: FIVE (5) YEARS
LOCATION:     QUEEN’S COLLEGE, GEORGETOWN, GUYANA
BACKGROUND:     The application of scientific principles and the conduct of relevant research are significant importance in identifying, assessing and realizing the potential of the resources   of Guyana. A good foundation in the sciences will enhance our students’ ability at Queen’s College to respond to the challenges of a rapidly changing world using the scientific approach. This document proposes the enhancement and modernization of the Biology, Chemistry and Physics Laboratories at Queen’s College, Guyana so that these dreams can be realized.
RATIONALE FOR THE STUDY OF SCIENCE AT QUEEN’S COLLEGE
Biology is the discipline in science which seeks to understand the organization of the organic world through an exploration of the structure and function of life forms at the molecular, cellular and ecosystem levels, as well as the complex interactions and interdependencies which occur at each of these levels. This knowledge provides the foundation for understanding the opportunities for promoting the well-being of humans and other living organisms in the environment. It generates an awareness of the importance of our biodiversity and the unique role of humans in conserving, protecting and improving the quality of the biological environment for future generations.
Chemistry is concerned with the physical and chemical properties of substances and the interaction of energy and matter. The study of Chemistry involves an investigation into chemical reactions and processes. The discipline seeks to explain predict events at an atomic and molecular level. Through the principles of Chemistry, students will understand everyday life, nature and technology, and the significance of the well-being of man and the environment.
Physics is concerned with systems, laws, models, principles and theories that explain the physical behavior of the universe. Physics is regarded as a fundamental scientific discipline since all advances in technology can be traced either directly or indirectly to these fundamental physics laws and theories, The study of Physics provides students with knowledge and understanding of how the principle of physics are applied to the development and production of machines and devices that contribute to the technological advancements of societies. (CXC/Syll 12)
Currently the college accommodates eight hundred and forty-nine students from various socio-economic backgrounds. However, it is with growing concern, that the members of the Administration and other Stakeholders realize that the existing laboratory facilities available at the college cannot address the needs of the learners and the Science Programmes offered by the Institution as the infrastructure as well as equipment and chemicals are either insufficient or outdated.

In order to facilitate the official proposal, the following are needed:
Complete enhancement and modernization of the seven laboratories at Queens’ College
Air conditioning systems installation in the Biology and Chemistry Stockrooms
Restoration of gasing system to Chemistry Laboratory A.
Implementation of gasing system for Chemistry Laboratory B and all Biology Laboratories.
Provision of projector and whiteboards for each laboratory
Restoration of the gas chambers in Chemistry Laboratories A and B.
One teacher’s desk and chair for each Science Laboratory.
One demonstration desk for Physics Laboratory A
Provision of equipment and Chemicals for each laboratory as stipulated below:

OUTCOME
Science plays a major role in the evolution of knowledge. It empowers us to use creative and independent approaches to problem solving. It arouses our natural curiousity and enables us to meet diverse and ever expanding challenged. It enhances our ability to inquire, seek answers, research h and interpret data. These skill lead up to the construction of theories and laws that help us explain natural phenomena and exercise control over our environment.
Science, is, thus an integral component of a balanced education. The most important natural resources in Guyana is its people. If Guyana is to play an integral role in the new global village, and survive economically, a sustained development of the scientific and technological resources of its people is essential.
Queen’s College, being the designated “Science School” of Guyana will benefit tremendously from this much needed intervention. The enhancement and modernization of the Science Laboratories art Queen’s College will by all means improve the teacher’s classroom delivery of the Science Curriculum and student’s performance both Locally and Regionally.

CONCLUSION
Funding this project will be a worthwhile investment. It would be all means contribute to the development of the ideal Guyanese and Caribbean person in the following areas: respect for human life, awareness of the importance of living in harmony with the environment, demonstration of multiple literacies, independent and critical thinking and, of course, innovative application of Science and Technology to problem solving. Students will learn to do, learn to be and learn to transform themselves in society.
