Earth Science

The Earth Science course is designed for students to interpret and understand the world in which you live. In order for that to take place, students will investigate and study interactions between the four major spheres of Earth (geosphere, biosphere, atmosphere, hydrosphere). These systems-the atmosphere, hydrosphere, geosphere, and biosphere-interact through time to produce the Earth’s landscapes, ecology, and resources. By studying these interactions, students will have an understanding of/ability to explain Earth’s: formation, processes, predictability of those processes, history, landscapes, how and why Earth changes over time, etc. The Earth Science course develops the explanations of phenomena fundamental to the sciences of geology & physical geography, including the early history of the Earth, plate tectonics, landform evolution, the Earth’s geological record, weather & climate, and the history of life on Earth.

The course will also explore how current actions of man interact and affect Earth’s spheres which lead to changes locally and globally. Additional topics include, but not limited to, scientific method, minerals, rocks, earthquakes, volcanoes, geologic time, meteorology, and, biogeochemical cycles. Students will explore these topics through laboratory exercises, small group activities, class discussions, projects, research, assessments, etc. Special attention will be paid to topics of current interest (e.g. recent earthquakes, tsunamis, global warming, etc.) and to potential careers in the geosciences. The curriculum is aligned with the Arizona Department of Education standards for science.


The Biology course is designed to be a continuance of student investigations in the life sciences. This is a laboratory-based science class in which students will learn more abstract concepts such as studying: the cell, the molecular basis of heredity, DNA & protein synthesis, biological evolution, interdependence of organisms, matter and energy, and organization in living systems, the behavior of organisms, and biological evolution. When students study these topics they gain an understanding of how organisms grow to how they interact with other organisms and their environment. The course will also explore how humans interact and affect the environment. Students will explore these topics through laboratory exercises, small group activities, class discussions, projects, research, assessments, etc. The curriculum is aligned with the Arizona Department of Education standards for science.


The Chemistry course will introduce you to the study of the physical world. The course is designed to continue the investigation process in the physical sciences. You will study aspects of the chemical world by being provided the necessary skills to become proficient in the concepts of chemistry. The curriculum includes more abstract concepts such as: structure of atoms, structure of properties of matter, and the conservation & interaction of energy, atoms & moles, periodic table & trends, ions & ionic compounds, covalent bonds & covalent compounds, chemical bonding, writing chemical equations & reactions, balancing chemical equations & reactions, stoichiometry, and the causes of change. Students will explore & investigate through experience in laboratory and fieldwork using the processes of inquiry. Students will be engaged in small group activities, class discussions, projects, research, assessments, and lab reports, etc. The curriculum is aligned with the Arizona Department of Education standards for science.

Serving English Language Learners (ELL)

The goal of Leupp Schools, Inc. for English Language Learners is to excel students to their highest potential so they can perform well at grade level in the mainstream classes. Rigorous English Language Arts instruction is necessary to prepare and achieve well in High School and Post-High School graduation pursuits.

First, learners are identified with the Primary Home Language Other Than English, PHLOTE, a survey provided by the guardians at time of school enrollment. Leupp School has an on-going school year process identifying, assessing and monitoring progress of English Language Learners.

In SY 2019-2020 all BIE Tribally-Controlled Schools were included in WIDA test administration, therefore, LSI has replaced AZELLA Test with WIDA ELL assessment.

Students already identified as ELL are provided Structured English Immersion, SEI, and has been assessed Spring 2022 with the World-Class Instructional Design & Assessment, WIDA. The current K-6 Journeys Reading Curriculum is embedded with ELL differentiated instructions, strategies and resources to assist teachers working with ELL students. The 7-12 Grade instructors seek on-line resources to enrich English Language Learning in Reading, Writing, Listening, Speaking, Vocabulary and Grammar.

ELL instructions are given by highly-qualified teachers at each grade level across the academic curriculum. LSI values and understands that it is important for ELL students to accelerate in English Language Arts to achieve in the mainstream society.

The Navajo classes emphasize Problem Based Learning and require a great deal of reading, writing, speaking and collaborative teamwork. For students with continuing education plans to universities and colleges, two years of Navajo language classes are requirements to apply for Chief Manuelito Scholarship.

Advocacy Program (LSI needs Teachers in all High School Subjects)

Tutoring: A large percentage of High School students are struggling in the Arizona State required classes to increase graduation rate. The NWEA assessment scores and classroom performance indicates there is a need for tutoring time, after school and summer school would increase graduation rate. After-school and afternoon class credit recovery: Many high school students transferring from other schools lacking Arizona State required credits for their cohort are in need of credit recovery. Other factors contribute to credit shortfalls, therefore credit recovery classes during the afternoon class periods and after school program would help the recover credits to increase high school graduation rate. Summer School: Summer School would help High School students recover ADE required credits to increase graduation rate.
