Landscape Architecture is the art of planning the appropriate use of land and designing the built environment based on an understanding of natural and cultural site characteristics, human need, and sound artistic and technical competence. Horticulture deals with the creation, production, distribution and use of fruit, vegetable, ornamental, greenhouse, turf, and specialty crops. Students studying Landscape Architecture/Horticulture concentrates on two major themes: (1) identification of trees, shrubs, evergreens, and groundcovers, propagation and culture of ornamental nursery stock, planting and establishment of aesthetically pleasing landscapes, management and care of urban landscape trees and shrubs, diagnosis and treatment of pests and diseases affecting landscape plants, and site design, land use, and urban planning. Students utilize the greenhouse for "hands on" lab activities as well as complete garden designs with detailed plant lists.

In Landscape Architecture students plan the appropriate use of land and designing the built environment based on an understanding of natural and cultural site characteristics, human need, and sound aesthetic and technical competence. Horticulture deals with the creation, production, distribution, and use of specialty crops. Students studying Landscape Architecture/Horticulture concentrate on two major themes: (1) botany and soil science, and (2) site design, land use, and residential planning. The greenhouse will be the laboratory setting for students' investigations and projects. Projects are developed to align to the District's emphasis on sustainability. Students are required to do independent research while completing total property designs with plant lists and detailed bids/proposals.

  • Course Number: 04040904

The goal of the Advanced Placement Program is to prepare students to successfully complete an AP exam. This course is designed to be the equivalent of a one-semester introductory college-level course in environmental science. It utilizes an interdisciplinary approach, combining elements of earth sciences, biology, and chemistry, to understand the interrelationships within the natural world. Students use scientific and quantitative methodologies to analyze and identify naturally occurring and man-made environmental problems, evaluate environmental and health risks, and explore solutions to minimize or prevent such risks. This rigorous course includes assigned readings, classroom lectures and discussions, a laboratory and field component, and outside research.
