Thames & Kosmos Science Advent Calendar Vol 2 - 24 STEM Experiments for Holiday Chemistry Fun
Published on 09/18/2026 at 12:12 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Thames & Kosmos Science Advent Calendar Vol 2 turns the December countdown into a small home lab, with 24 individual science experiments packed into daily boxes for children to open as they approach Christmas.
Daily STEM Experiments Behind Each Door
According to the Science Advent Calendar Vol 2 description, the set includes 24 unique experiments that children can perform day by day during the holiday season.
The manufacturer notes that the experiments cover a range of scientific topics related to chemistry, biology and physics, so the calendar does not focus only on one discipline.
The same description explains that each daily box unfolds to reveal written step-by-step directions and a brief scientific explanation for the activity, which helps children connect the experiment to the underlying concept.
Included Materials and Household Add-ons
The Science Advent Calendar Vol 2 comes with most of the specialized materials and tools needed for the 24 activities, while the remaining items are common household materials such as vinegar, lemon juice, baking powder and cotton swabs, as listed in the related product listing.
The manufacturer emphasizes that the daily experiments are designed to be completed quickly, so children can perform them in a short session as part of their daily holiday routine.
With 24 separate boxes that each contain experiment materials and illustrated instructions, the calendar provides a structured way for families to organize a daily STEM activity through the Advent period.
Positioning in the Science Advent Calendar Market
The Science Advent Calendar Vol 2 forms part of a broader range of STEM-themed advent calendars from the same brand, which includes earlier versions that also feature 24 experiments covering chemistry, biology and physics topics, as described in the earlier Science Advent Calendar description.
In comparison with generic chocolate advent calendars, the Science Advent Calendar Vol 2 replaces confectionery with experiment components and printed instructions, offering a structured hands-on activity each day rather than a food treat.
The inclusion of multiple disciplines such as chemistry, biology and physics positions the calendar as a general STEM product rather than a single-subject chemistry kit, giving families a variety of topics across the 24 days.
Use Case and Limits
The focus on quick, guided experiments with most materials supplied makes the Science Advent Calendar Vol 2 suitable for families who want a daily STEM activity that fits into a school-day routine without requiring extensive preparation.
Because some experiments call for household ingredients such as vinegar and baking powder, adults need to provide supervision and access to a kitchen or similar work area when children perform the activities.
Compared with year-round chemistry sets that offer larger quantities of reagents and equipment, the Science Advent Calendar Vol 2 concentrates on short, self-contained tasks designed specifically for the 24 days leading up to Christmas.
