The document provides instructions for a learning center activity where students will use different tools - a thermometer, ruler, magnifier, and balance - to collect data about various objects. Students will visit four stations, one for each tool, where they will measure features of objects like temperature, length, details visible under magnification, and relative weight. They will record their observations and answers to questions on index cards. Afterwards, students will evaluate by sharing what each tool revealed about the objects.
