Kindergarten Science Fair Projects

Our Kindergarten Science Fair Projects collection offers playful, low-pressure ideas for children around ages 5–6 who are ready to explore cause and effect. Homeschoolers, afterschooling families, and caregivers will find vetted, secular projects that focus on observing, comparing, and describing rather than formal hypotheses or data tables. Kids might explore sinking and floating, plant growth, color mixing, or simple magnetism using safe, everyday materials. Each project is reviewed for safety, simplicity, and developmental appropriateness, with adaptations for ADHD, autism, sensory sensitivities, or 2e learners who may need extra support. Use the filters to sort by topic, mess level, and time required. If you’re unsure how to participate in a “science fair” with a kindergartner without turning it into a parent project, Modulo’s AI learning concierge can suggest gentle, child-led options that fit your family.
