This Grade 1 light experiments sheet challenges first graders to predict outcomes with flashlights, shadows, and see-through materials. Students answer four multiple choice questions about shadow size, surface choice, and transparent windows, then complete five fill-in sentences about shadow direction, two-lamp shadows, and sharpness near a plain wall. Every question includes a hint and a plain-language explanation to deepen science thinking.
