Apologia

Apologia is the best-known Christian science curriculum in the homeschool world. Founded by Dr. Jay Wile and now published by Apologia Educational Ministries, its Exploring Creation series has been a homeschool standard for elementary, junior high, and high school science since the early 1990s. This page covers everything an Arizona family needs to evaluate Apologia: the philosophy, the workload, the pricing, the formats, and how to purchase it with Arizona ESA funds.

Use the sections below to decide whether Apologia fits your child before committing to a full year of materials. For broader options, see our homeschool curriculum directory and our Arizona ESA homeschool guide.

Quick Facts

Overview

Apologia is best known as a Christian science curriculum, though it also publishes Bible, worldview, writing, and Bible Survey programs. Its flagship Exploring Creation series spans K through 12.

The elementary books use a Charlotte Mason-influenced approach: a conversational text, narration, and a notebooking journal where the student records what they learn. The junior high and high school courses are textbook-and-lab courses written directly to the student, with most subjects designed for independent study.

Apologia is the standard self-paced Christian high school science curriculum used by classical schools, hybrid programs, and homeschool co-ops across Arizona.

Who This Curriculum Is Best For

Apologia is a strong fit for families who want serious science without losing their faith framework. It works well for:

• Christian families who want science taught from a biblical worldview
• Parents who want a curriculum the student can run on their own in junior high and high school
• Co-ops and hybrid schools that need a shared lab-science spine
• Students preparing for college-level biology, chemistry, and physics
• Families who value notebooking and narration in the elementary years

Who Should Consider Something Else

Apologia is not for everyone. Other publishers may fit families who:

• Want a secular or neutral science curriculum
• Need a young-elementary program with more hands-on kits and fewer pages of reading
• Prefer video-led instruction in elementary
• Need a gentler, lower-reading-load option for a struggling reader
• Want a single all-subject boxed curriculum instead of stand-alone science

For neutral options, see our curriculum directory.

Educational Philosophy

Apologia uses a conversational, narrative approach. Authors write directly to the student in a friendly voice, weave in their own questions, and frequently pause for "On Your Own" questions and notebooking.

The elementary books follow a Charlotte Mason-style rhythm: read, narrate, record in the notebooking journal, and complete a hands-on activity. The junior high and high school books move to a traditional textbook pattern with modules, on-your-own questions, study guides, tests, and labs.

Across every level, Apologia teaches that science is one of the best ways to know the Creator. Doctrine and worship are not bolted on at the end of a lesson - they are part of how the material is taught.

Christian Worldview

Apologia teaches from a distinctly Christian, young-earth creationist worldview. Origins, age of the earth, and design in nature are addressed directly, not avoided.

Apologia also publishes a "What We Believe" worldview series for elementary and Bible Survey courses for older students. These resources are designed to help families teach a coherent biblical worldview alongside their academics.

This is a major draw for many faith-based families. It is also the main reason secular homeschoolers look elsewhere.

Grade Levels and Subjects Covered

Apologia covers K through 12 with a strong science focus and growing offerings in Bible, worldview, writing, and language arts.

Elementary science (typically K-6, family-style):

• Exploring Creation with Astronomy
• Exploring Creation with Botany
• Exploring Creation with Zoology 1 (Flying Creatures), 2 (Swimming Creatures), and 3 (Land Animals)
• Exploring Creation with Anatomy and Physiology
• Exploring Creation with Chemistry and Physics
• Exploring Creation with Earth Science

Junior high science (typically 7-8):

• General Science
• Physical Science
• Marine Biology (junior high or early high school)

High school science (typically 9-12):

• Biology
• Chemistry
• Advanced Biology (The Human Body)
• Advanced Chemistry
• Physics
• Advanced Physics

Other subjects:

• What We Believe worldview series (elementary)
• Bible Survey courses (secondary)
• Writers in Residence and Readers in Residence (language arts)
• Health and Nutrition

Daily Time Commitment

Apologia is generally a one-subject-at-a-time curriculum, not a full daily schedule.

• Elementary. 30 to 60 minutes, two to three days a week, taught family-style. Many families spread one book across a full year.
• Junior high. 45 to 60 minutes a day, five days a week, with labs every week or two.
• High school. 60 to 90 minutes a day, five days a week. Lab days run longer. Plan for one credit per year per course.

That makes Apologia easy to fit alongside a different core curriculum.

Parent Preparation Required

Prep depends on the level.

• Elementary. The parent reads aloud, leads narration, and runs simple hands-on activities. Lab supplies are mostly household items. A planning guide makes daily flow easy.
• Junior high. The parent assigns reading, checks on-your-own questions and tests, and supervises labs.
• High school. Designed for independent study. The parent grades tests with the included solutions and test manual, supervises lab safety, and confirms lab reports.

Optional add-ons reduce parent load further: Apologia's on-demand video instruction walks students through every lesson and lab, and audio versions of many courses let students listen while reading.

Student Independence Rating

Independence is moderate in elementary and high in junior high and high school. By Biology and Chemistry, most students run their own daily reading, questions, and study guides, with the parent grading and supervising labs.

This is one of the most popular Christian high school science options for busy parents and for students with a packed schedule.

Teaching Format

Apologia offers several formats that can be mixed and matched:

• Textbook. The core of every course.
• Notebooking journal. Elementary and junior high. Provides daily lessons, copywork, vocabulary, narration prompts, and activity pages.
• Student Notebook. High school. Holds module notes, study questions, and lab write-ups.
• Audiobook. Available for many elementary and secondary courses for auditory learners.
• On-demand video. Streaming lessons taught by Apologia instructors for many junior high and high school courses, with labs filmed for at-home use.
• Live online classes. Through Apologia Live Classes, with a live teacher, weekly assignments, and grading.

The video and live class options are popular with co-ops and hybrid schools, and with families tackling Chemistry, Advanced Biology, or Physics at home.

Pricing and Ongoing Costs

Apologia is purchased course by course, not as a single boxed grade.

Typical price ranges (always confirm current pricing on the Apologia site):

A typical high school science year runs $150 to $300 in print materials, plus a one-time lab investment in microscope and chemistry equipment that can be reused for multiple courses.

Arizona ESA Eligibility and Purchasing Guidance

Apologia is an Arizona ESA curriculum option that families can purchase with ESA funds.

ClassWallet is the financial management platform for the ESA program. Parents can make tuition payments, purchase educational items, and pay for other education-related expenses through the ClassWallet Marketplace.

The practical flow:

1. Log in to ClassWallet through the ESA Applicant Portal.
2. Select the correct student profile for families with more than one child.
3. Search the marketplace or use Pay Vendor for Apologia.
4. If a specific item is not listed, use Direct Pay with an invoice or submit for reimbursement.
5. Upload a detailed invoice and proof of payment.

A few practical notes for Apologia specifically:

• Textbooks, notebooking journals, and student notebooks are clearly curriculum and routinely allowable.
• Lab kits, microscopes, dissection specimens, and chemistry equipment are typically allowable as required supplemental science materials. Save the course page or syllabus that lists the equipment.
• Apologia Live Classes are usually paid as tuition. Confirm the vendor is set up in ClassWallet first.

The core subject rule matters here. Core subjects required by Arizona ESA include science. Apologia covers it deeply.

A 2026 ballot measure would require the Arizona Department of Education to maintain a list of approved curricula and supplemental material. Rules can shift, so always check the current ESA Parent Handbook before buying.

Final Verdict

Apologia is a top-tier choice for Christian families who want serious, faith-integrated science from elementary through high school. The elementary series is gentle and engaging. The secondary courses are real, lab-based, college-prep science.

It is not the right fit for secular families, and the lab costs are higher than text-only science programs.

Recommendations by family type:

• Christian family wanting strong science. Strong fit at every level.
• Busy or working parent of a high school student. Add on-demand video or Apologia Live Classes.
• Charlotte Mason family. Elementary notebooking journals are an excellent match.
• Struggling reader. Use the audio version or pair with a gentler elementary science.
• Secular family. A neutral science curriculum instead.
• Arizona ESA family. Fully eligible. Purchase through ClassWallet and keep clean records of textbooks, journals, and lab supplies.
