Summary A hands‐on activity is described in which students attempt to measure something that they cannot see. In small groups, students estimate the number of marbles in sealed boxes. Next, students’ estimates are compared with the actual numbers. Last, values from both the students’ estimates and actual numbers are used to explain measurement theory and reliability.
