Science Advent Calendar | Vol. 4

Count down to Christmas with a new science surprise every day with the Thames & Kosmos Science Advent Calendar Vol. 4! Instead of candy or tiny toys, this educational Advent calendar gives curious kids 24 days of hands-on science experiments leading up to Christmas. Open one numbered box each day to discover new experiment materials along with illustrated step-by-step instructions. Activities explore a variety of scientific topics, including chemistry, biology, and physics, with experiments designed to be completed relatively quickly using the included supplies plus common household items when needed. Each daily box cleverly unfolds to reveal instructions and explanations, so kids aren't just completing an experiment—they're learning about the science behind what they observe. It's a fun way to combine a Christmas tradition with STEM learning, science experiments, discovery, and screen-free activities. A great holiday gift for kids who love science kits, experiments, STEM toys, and learning how things work.
