Light beams, animal defenses, the pattern of the sun and moon — 1st grade science is full of phenomena kids genuinely wonder about. These 1st grade science lessons align to the NGSS performance expectations for the grade: investigating light and sound (1-PS4), designing solutions inspired by plant and animal structures (1-LS1), observing predictable patterns of the sun, moon, and stars (1-ESS1), and tracking the effect of sunlight on Earth's surface.

Each slide deck opens with a hook, walks through an investigation or modeling activity, and closes with discussion prompts that push students to explain their observations. The slides carry the structure so you can focus on facilitating the hands-on parts.

Everything is editable in Chalkie: adjust the activities to the materials in your supply closet, add photos from your own schoolyard, or simplify the vocabulary. Preview the lessons free and adapt them in minutes rather than rebuilding from scratch. Your planning time goes to the investigation, not the slides.
