Earth Science tutoring curriculum256 skills across 10 units
Earth Science Practices and Reference Tools
Launches Earth Science through systems and representations: evidence practices, sphere interactions, models, maps, reference tables, measurements, and data displays that recur across every domain. Topics: Science Practices and Evidence, Earth Systems, Scale, and Interaction, Reference Tables, Units, and Formula Tools, Maps, Coordinates, and Profiles, Data Displays, Trends, and Reliability.
Plate Tectonics and Earth's Interior
Uses indirect evidence and visual models to reconstruct Earth's interior, plate motion, boundary settings, and long-term tectonic-system interactions. Topics: Interior Evidence and Layers, Evidence for Plate Tectonics, Plate Boundaries and Map Patterns, Plate Motion Mechanisms, Tectonic Features and Long-Term Change.
Minerals, Rocks, and the Rock Cycle
Treats minerals and rocks as evidence of composition, formation environment, and Earth-system cycling, not isolated vocabulary. Topics: Minerals, Igneous Processes and Rocks, Sediments and Sedimentary Rocks, Metamorphic Processes and Rocks, Rock Cycle and Earth Materials Synthesis.
Volcanoes, Earthquakes, and Crustal Deformation
Interprets volcanoes, earthquakes, deformation, and mountain building as event evidence plus hazard-risk reasoning after the tectonic frame is in place. Topics: Volcanoes, Earthquakes and Seismic Waves, Crustal Deformation and Mountains, Dynamic-Crust Hazard Synthesis.
Geologic Time, Earth History, and Life
Reconstructs deep time by combining relative and numerical dating, fossils, planetary evidence, continental change, and life-atmosphere-ocean-rock feedbacks. Topics: Relative Dating Principles, Correlation and Fossil Evidence, Numerical Dating and Time Scale, Earth History, Life, and System Change, New York and Regional Geologic History.
Weathering, Water, and Landscapes
Connects weathering, mass wasting, groundwater, streams, deserts, and landscape evolution as surface-system responses to water, gravity, climate, bedrock, and tectonics. Topics: Weathering, Erosion, and Soil, Mass Wasting, Streams, Rivers, and Floods, Hydrologic Cycle and Water Budgets, Groundwater and Karst, Landscapes, Wind, and Deserts.
Oceans, Coasts, and Ice
Uses profiles, maps, and sequences to reason about ocean basins and water, currents and tides, shoreline change, glaciers, ice-age evidence, and sea-level feedbacks. Topics: Ocean Basins and Ocean Water, Ocean Motion and Circulation, Coasts and Sea-Level Change, Glaciers and Glacial Landforms, Ice, Oceans, and Cryosphere Feedbacks.
Atmosphere, Weather, and Climate
Connects atmospheric energy and weather maps with climate evidence: variables and instruments, storms, forecasting, controls, paleoclimate, recent change, models, and feedbacks. Topics: Atmospheric Structure and Energy, Weather Variables, Instruments, and Maps, Air Masses, Fronts, and Forecasting, Severe Weather, Climate Systems and Change.
Resources, Hazards, and Human Sustainability
Uses maps, data, and tradeoff models to reason about resources, hazards, human impacts, climate responses, engineering constraints, and sustainability decisions. Topics: Natural Resources and Energy, Human Impacts on Earth Systems, Natural Hazards and Risk, Engineering Solutions and Tradeoffs, Sustainability and Global Change Synthesis.
Space Systems and Planet Earth
Closes the course by using evidence from light, spectra, H-R diagrams, orbits, planetary surfaces, and Earth-Sun-Moon geometry to place Earth in cosmic context. Topics: Universe Evidence, Stars, Solar System Motions and Objects, Earth-Sun Cycles, Moon, Eclipses, and Tides.

Why families switch
Everything an hourly tutor can't be
On demand, 24/7
No scheduling, no weekly slot. Help is there during homework at 9pm and the morning before the test.
A fraction of the cost
Unlimited sessions on a flat plan instead of paying a human tutor by the hour.
Truly personalized
Aristotle tracks every skill your child has mastered and teaches at their exact frontier: never too easy, never too far ahead.

FAQ
Common questions about online earth science tutoring
Aristotle's earth science course maps 256 individually tracked skills across 50 topics: plate tectonics and Earth's interior, minerals and the rock cycle, earthquakes and volcanoes, geologic time, weathering and water, oceans and ice, weather and climate, natural resources and hazards, and space systems. The tutor always knows what your child has mastered and what comes next.
Your child talks through problems out loud while working with Aristotle on a shared whiteboard. Earth science leans heavily on figures, so sessions are built around the same maps, data tables, and reference charts your child sees in class and on tests. Sessions start whenever your child is ready, with no scheduling: during homework at 9pm, or the morning before a test.
Science tutors typically charge $50 to $90 an hour, which comes to $600 to $1,080 a month at three hours a week. Aristotle costs $299 a month for unlimited sessions across every subject, or $49 for a single session.
Chatbots hand your child the answer and forget them when the chat ends. Aristotle teaches the way expert tutors do: it asks your child to explain their thinking, finds the misconception underneath a wrong answer, and guides them with questions until they can solve it themselves. It also carries the learning process across sessions, remembering what your child has mastered and planning what to teach next, like a personal tutor who never forgets.
Yes. Parents get a summary after every session, and the parent dashboard shows which skills your child has mastered and where they are stuck. Sessions are reviewed, and every tutor response is checked before it reaches your child.
Yes. Earth science struggles are rarely about memorizing facts. Most trace back to an earlier skill, often reading a data table, interpreting a graph, or using a reference chart. Each skill on the map is linked to its prerequisites, so Aristotle finds the exact earlier skill that is missing and rebuilds from there, instead of repeating the same lesson louder.
Yes. Earth science is often a student's first high school level science course, sometimes taken as early as 8th grade, and Aristotle teaches at your child's frontier rather than their grade level. The course opens with science practices, reference tables, and map reading, so younger students build the figure-reading skills the rest of the course depends on.
Yes. Earth science skills are aligned to the HS-ESS Earth and Space Sciences performance expectations in the New York State Science Learning Standards, and the tutor personalizes to your child's actual class. Share the syllabus, textbook, or upcoming test topics and sessions will follow what is happening in school.
