Children are given the first sheet to draw and label all the "artifacts" in their own bedroom on one sheet. When completed, their drawing is given to another child who will be the "scientist". The "scientist" will study the drawing and the artifacts it contains, and record information they learned from them. They can do it literally, ("the person likes the color blue", or make more sophisticated inferences, such as; "there are books in the room, so they must like to read"!) They can present their findings to the class.
