Mini-lesson — Turn problems into inventions

Find a problem: What bug or bother do people face?
Offer a solution: Your invention should fix or reduce the problem.
List features: 2–3 special parts or actions that make it work.
Explain benefits: Who does it help and how?
Name it: A short, catchy name helps readers remember it.
