At an Extension youth agricultural science center, our team developed and pilot tested a five-lesson weather and climate science curriculum for middle school–aged youths. As part of the endeavor, we conducted an item analysis of the five worksheets used across the lessons and determined relationships between worksheet scores and pretest/posttest science comprehension improvement scores. Results from 88 primarily Hispanic eighth graders indicated that worksheet performance was related to overall science comprehension, science knowledge, and weather and climate resiliency in agriculture and natural resources lesson improvement scores. Results support the use of formative scaffolding tools such as worksheets in Extension youth programming to improve youth science comprehension.
