What's the difference between Science Units and BLSK task sets?
Science Units take students through a full arc of a concept. Students engage in data analysis, laboratory investigations, and text-based reading and writing tasks. Units are designed to replace, not supplement, traditional units.
BLSKs include target reading and writing tasks that complement traditional science instruction. BLSKs support students' literacy development in addition to building their knowledge of science concepts.
The IFL offers two types of instructional materials in science: Science Units and Building Literacy and Science Knowledge (BLSK) task sets. Both are designed to help ensure that students develop conceptual understanding of fundamental scientific concepts and to apprentice students in the ways of reading, writing, talking, and reasoning in science.
Our Science Units and BLSK task sets can be used as:
- high-quality curricula to advance student learning and to fill in gaps in existing curricula;
- models of coherent and challenging curricula to advance educator learning; and
- templates to guide the development and revision of school, district, or state curricula.
The IFL offers professional development to help educators use and learn from our instructional materials.
