The field at a glance

Not a scattered list.
A connected discipline.

Every Knowledge Tree sits inside a larger map of concepts, practices, vocabulary, prerequisites, and meaningful applications.

01

Life science

Organisms, cells, genetics, ecology, evolution, anatomy, physiology, microbiology, and biotechnology.

02

Physical science

Matter, energy, forces, motion, waves, chemistry, physics, and materials science.

03

Earth & space

Geology, weather, climate, oceans, astronomy, planetary science, and earth systems.

04

Engineering & design

Defining problems, prototyping, testing, systems thinking, electronics, robotics, and design tradeoffs.

05

Scientific practice

Observation, measurement, experimentation, modeling, data analysis, replication, and scientific communication.

06

Science in society

History and philosophy of science, ethics, technology, public claims, uncertainty, and stewardship.

K through graduate study

Expectations deepen.
The roots stay connected.

These are representative Knowledge Trees, not a fixed or final list. Families can build a focused path, a complete sequence, or advanced independent study.

Active microlearning

Study becomes something
the learner actually does.

Most digital lessons take 5–15 minutes and develop one clear objective through listening, reading, watching, trying, moving, making, practicing, feedback, and recall. Narrated instruction, adjustable playback, and transcripts sit alongside visual, read/write, interactive, kinesthetic, and hands-on elements. Parents can prefer or disable optional modes for each learner while sustained reading, labs, projects, writing, discussion, and performance remain wherever the objective calls for deeper work.

01

Home-ready laboratories

Safe investigations identify household, kit, virtual, or supervised laboratory requirements before enrollment.

02

Living field notebooks

Observations, photographs, sketches, measurements, specimens, and questions become longitudinal evidence.

03

Simulation & modeling

Learners vary systems that are too small, large, slow, fast, expensive, or dangerous to test directly.

04

Engineering challenges

Build-test-improve cycles connect scientific understanding to useful design under real constraints.

Evidence of learning

Mastery is more than
a completed screen.

Lab notebooks and reportsData tables and analysisModel-based explanationsField observationsEngineering design reviewsResearch proposals and literature reviews

Transparent worldview

Choose the framing.
See it before assigning.

CHRISTIAN PATHWAY

Treats creation, stewardship, human dignity, scientific vocation, and disputed interpretive questions explicitly while representing scientific evidence and alternative positions accurately.

SECULAR / ACADEMIC PATHWAY

Uses mainstream disciplinary methods and non-confessional framing, with worldview-sensitive topics and sources clearly identified for parents.

Knowledge Tree pages identify perspective, sources, debated questions, prerequisites, and objectives. Parents retain final control.

Inside every Knowledge Tree

Complete enough to teach.
Clear enough to trust.

01

Published scope & sequence

Objectives, prerequisites, vocabulary, lesson order, worldview, materials, estimated time, and mastery expectations.

02

Multimodal micro-lessons

One focused concept through coordinated visual, auditory, read/write, interactive, movement, and hands-on elements—with feedback and retrieval.

03

Assessment & grading

Checks, quizzes, tests, projects, and writing—with automatic rubric grading, evidence-linked feedback, and parent review.

04

Adaptive support

Readiness checks trace weak roots, assign proportionate repair, verify retention, and return learners to the goal.

05

Parent controls

Adjust pace, tutors, worldview, due dates, interventions, lesson modes, and whether suggested writing grades post automatically or require approval.

06

Permanent records

Lesson history, grades, attempts, feedback, mastery evidence, hours, portfolio artifacts, and unofficial transcripts.
