Review: Can't Recommend Enough! - I can't recommend this enough!! My 5 year old is so excited for his experiment each day. The experiments are very fun for him, and simple enough that he can do most with little to no parent involvement (and the independence adds to the his love of it). I just have to help him read the simple directions and short explanation. As a busy parent, I also appreciate the minimal to no cleanup needed after! ## Features - Celebrate the winter holiday season with science! - This advent calendar includes 24 unique science experiments to do as kids count down the days to Christmas. - Experiments are quick to execute and cover a variety of scientific topics related to chemistry, biology, and physics. - Each daily box cleverly unfolds to reveal an instruction manual with step-by-step directions and scientific explanations; Adds an educational twist to a fun, wholesome family tradition! - Most materials and tools included; additional materials are common household items such as vinegar, lemon juice, baking powder, and cotton swabs. ## Technical Specifications | Specification | Value | |---------------|-------| | Item Dimensions | 14.6 x 2.4 x 11.5 inches | | Theme | Christmas | ## Images ![The Thames & Kosmos Science Advent Calendar | 24 STEM Experiments in Chemistry, Biology & Physics | Great for Winter Holiday Celebrations | Conduct Daily Experiments | Fun, Wholesome Family Tradition - Image 1](https://m.media-amazon.com/images/I/812W59MQecL.jpg) ![The Thames & Kosmos Science Advent Calendar | 24 STEM Experiments in Chemistry, Biology & Physics | Great for Winter Holiday Celebrations | Conduct Daily Experiments | Fun, Wholesome Family Tradition - Image 2](https://m.media-amazon.com/images/I/813TKzKcEyL.jpg) ![The Thames & Kosmos Science Advent Calendar | 24 STEM Experiments in Chemistry, Biology & Physics | Great for Winter Holiday Celebrations | Conduct Daily Experiments | Fun, Wholesome Family Tradition - Image 3](https://m.media-amazon.com/images/I/81pFTLMygTL.jpg) ![The Thames & Kosmos Science Advent Calendar | 24 STEM Experiments in Chemistry, Biology & Physics | Great for Winter Holiday Celebrations | Conduct Daily Experiments | Fun, Wholesome Family Tradition - Image 4](https://m.media-amazon.com/images/I/81B8MOq95jL.jpg) ![The Thames & Kosmos Science Advent Calendar | 24 STEM Experiments in Chemistry, Biology & Physics | Great for Winter Holiday Celebrations | Conduct Daily Experiments | Fun, Wholesome Family Tradition - Image 5](https://m.media-amazon.com/images/I/81TjeBNkDNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Holiday Fun Meets Science: A Perfect STEM Advent Tradition *by N***. on July 28, 2025* The Thames & Kosmos Science Advent Calendar is such a fantastic way to make the holiday season both fun and educational.
