Science Experiments

Wonder-first — pour, mix, observe.

64 activities

Science experiments for kids should start with a real question, not a worksheet. These activities lean wonder-first — pour, mix, observe, wonder aloud — and are safe for kitchen counters. Ages range from toddler-friendly sensory chemistry to school-age physics and life-cycle observation. Each experiment lists the concept it demonstrates and the developmental skills it builds.
