Make it concrete
Analogy
Digestive system is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Why it matters
Real-world use
Digestive system helps explain health, ecosystems, medicine and how organisms stay alive. Example: Amylase breaks starch into sugars in the mouth and small intestine.
Why now: Real examples make the mark-scheme words easier to remember.
Do this: Connect one key word to the example.
