Weather data, invisible forces, life cycles, and family traits: the NGSS gives 3rd grade a genuinely interesting year of science. These lessons cover the grade's core performance expectations — representing seasonal weather data in tables and graphs (3-ESS2), investigating balanced and unbalanced forces (3-PS2), modeling diverse life cycles (3-LS1), and interpreting evidence that traits are inherited (3-LS3).

The decks are structured around the science practices the standards actually name. Students do not just hear about forces; the slides set up an investigation and ask them to gather evidence. The weather lesson has the class building data displays, and the inheritance lesson centers on interpreting trait data.

Present these 3rd grade science lessons as designed, or adapt them first in Chalkie: use your city's real weather data, swap the organisms in the life cycles lesson, or add a claim-evidence-reasoning slide. Free to view, and a free account makes every slide editable.
