Weather data, forces, life cycles, and heredity: third grade is where NGSS science starts to look like real data work. These 3rd grade science worksheets cover four performance expectations: weather and climate (3-ESS2), forces and interactions (3-PS2), life cycles (3-LS1), and inheritance and variation of traits (3-LS3).

Students represent weather data in tables and graphical displays to describe seasonal conditions, plan investigations into balanced and unbalanced forces, develop models showing that organisms have unique and diverse life cycles, and interpret data as evidence that plants and animals inherit traits from their parents.

Each worksheet gives students a structured place to record, graph, and explain, which makes them a natural companion to hands-on investigations or a ready-made check at the end of a unit. Download them free, print, and go. If you need a version with your own data table or local weather examples, edit and regenerate it in Chalkie after a free signup.
