‘Tis the season for science! Christmas time is experimentation time. Discover something new and amazing every day leading up to the holiday. With this advent calendar, children open a new box each day to find new equipment or materials and the instructions for a science experiment. The experiments can be done quickly and only require additional items that are commonly found in every household. Each of the 24 beautifully designed boxes includes unique experiment materials and expertly written and illustrated instructions. For Ages 8 and up. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
