Get help with Biology 20
Most tutoring makes you sit through material you already know. MapleMind flips that: pick the exact skill that's causing trouble — any of the 26 below — and the tutor teaches just that one, step by step, as many times as it takes. Ask questions in plain words, any time of day, in English, French, or 12 other languages.
The official Saskatchewan Biology 20 curriculum
Saskatchewan defines Biology 20 by strands and outcomes. MapleMind teaches the same curriculum reorganized for one-skill-at-a-time tutoring — the table shows exactly where every official strand lands, and the ministry's own wording is quoted under each unit below.

How MapleMind teaches Biology 20 — every unit, lesson, and skill
Every skill below runs as a short session: a plain-words lesson, a worked example, solving it together, then a five-question skill check that earns up to three stars. Guided Mode keeps it teaching instead of answer-handing — turning it off needs a parent's password.
Unit 1Introduction to BiologyOfficial strand · Strand U1
The nature of the study of biology, microscope technique, and the role of theory in biology.
The Nature of the Study of Biology

Using the Microscope
- Examining cells with a microscopeBIO20-U1.2 — Use a light microscope to examine cells: handle and care for the instrument, prepare and view slides, sketch the field of view, and estimate object sizes.
Theory, Cell Theory, and Natural Selection
- The importance of theory in biologyBIO20-U1.3 — Explain the importance of theory in biology, using the development of cell theory and the principles of natural selection identified by Darwin and Wallace as worked examples of how theory explains and unifies observations and can change.
