Choose a common object from your house. Observe it carefully. What inferences can you make observing its shape only? In a Google Doc, Analyze it, come out with as many questions as possible about it (for example think about its function? What human needs does it meet? etc...) Answer as many question as you can using your existing knowledge. Try to apply the knowledge you have gained during your high school career to the description of the object (from all subjects not only science).
