Biology

Biology invites kids and teens to explore living systems—from cells and DNA to ecosystems and human anatomy. Our Biology collection brings together vetted, secular resources for homeschoolers, afterschooling families, and caregivers who want more than dry memorization. You’ll find mastery-based curricula, lab-rich programs, interactive simulations, field-guide-style nature study, and tutors who make complex concepts clear. Every resource is reviewed for scientific accuracy, developmental fit across middle and high school levels, and practical guidance for doing labs at home, with or without a full science lab. Use the filters to sort by level (introductory, middle school, high school, or advanced), format (textbook-based, online course, video-rich, or hands-on), and learning needs including ADHD, dyslexia, autism, giftedness, or 2e. Many families also combine biology with outdoor observation or medical-science electives from Modulo. If you’re unsure which biology program matches your learner’s level and comfort with labs, Modulo’s AI learning concierge can recommend options tailored to your goals.
