Choose a question, a gentle action, a label or how to show your idea.
Say what you predict before the action or the next source part.
Ask the adult to check the material and safe stop. You can stop, watch or direct the adult.
Keep what you actually noticed, even when it surprises you. Write not observed if you could not find out.
Tell which material you followed and how you know its source.
Choose words, drawing, pointing, speech, signing or a helper who writes your words.
Keep prediction, finding and invented model separate. Ask a new question.
A changed shape need not make a new material. A curve may stay; a piece need not spring back. Do not pull harder to get a result. You can work with a described source and leave actual handling unobserved.
