This is a lesson about sampling and estimation. Learners will make an object called a sampling window through which they will first count the number of stars on a printed page and estimate the total number of stars on the page, then count and estimate the number of letters on a newspaper page, and finally count and estimate the number of stars in the nighttime sky. While most of this activity can be done in a classroom, the final part of the activity requires access to a darkened sky location at night. This is Actividad 7.1 as part of El Universo a Sus Pies, a Spanish-language curriculum available for purchase.
