How to use the workspace
Start with the question, the scale, and the vocabulary that make the idea visible.
Read an original explanation grounded in a reviewed educational source.
Close the page, answer from memory, and use feedback to decide what to revisit.
Science lessons use original wording and visible references. They are educational materials, not professional, clinical, laboratory, or academic-credit instruction. External data explorers may change independently of the reviewed lesson text.
