Thames & Kosmos Science Advent Calendar Vol. 2 (2024) – Holiday STEM kit for kids (ages 8+)
Product description
What it is (and why kids tend to like it)
This Thames & Kosmos Science Advent Calendar Vol. 2 is a holiday countdown kit built around hands-on experiments. Instead of just opening a door each day, you get something to try—day by day—across different areas of science. In practice, that means the “advent calendar” format stays engaging, while the learning element isn’t stuck in worksheets.
It’s aimed at children aged 8 and up, so it sits in that sweet spot where many kids can follow simple steps and still feel a real sense of achievement (as long as an adult reads the instructions and helps with any safety basics).
The essentials: science themes across 24 days
The kit is designed to cover multiple STEM areas, including chemistry, biology and physics. The premise is straightforward: each of the 24 days has a self-contained activity, so there’s less faffing about and more doing. If you’re looking for “something educational” that still feels like a proper activity rather than a chore, this is the type of product to consider.

On paper, the multidisciplinary approach is a big part of its appeal. Kids who get bored easily by one topic may enjoy the change of pace from day to day.
What you’ll notice day to day
A key selling point here is that it’s presented as a complete set: the activities are meant to come with the materials included, so you shouldn’t need to track down extra supplies. That can genuinely change how often you stick with the plan—holiday periods are busy, and discovering you’re missing items is an easy way to lose momentum.


A small practical example: if you open Day 1 in the kitchen or dining room, you can usually set up, do the experiment, and tidy up without clearing a whole workspace for days. It’s the kind of format that suits a “quick but hands-on” session during the run-up to Christmas.
Where it shines (and what it’s best suited for)

The calendar format naturally encourages family involvement. It can work for solo play, but it also makes sense if you want to do a short shared activity with your child during the festive season.
Worth considering if: - you want a holiday countdown that leans into STEM rather than just novelty - the child enjoys following instructions and trying small experiments - you prefer a kit where materials are included, reducing extra shopping - you’re aiming for something that can be used in short family sessions
It also says it supports 1+ players, which fits households with one child well, and group use if you’re doing it as a family activity.
Limitations to bear in mind before buying
Advent calendars are inherently paced—24 days means you’ll be doing several sessions over the holiday period, not one big weekend project. So if you’re after a single long experiment or a kit you can keep using throughout the year, this may feel more like a seasonal activity.

Also, even with age-appropriate experiments, chemistry-style activities sometimes need adult oversight. The information provided doesn’t spell out every safety detail, so it’s sensible to plan for supervision and to read through the instructions before starting.

Should you buy it?
It’s a good fit if you want a festive STEM activity that turns the daily countdown into something hands-on, with a multidisciplinary mix of science topics. The included materials angle is particularly useful if you’d rather not gather lots of extras before you can start.

You may want to skip it if your child is younger than the stated age guidance, or if you don’t realistically have time to keep up with a 24-day sequence during the holidays. It might not suit you either if you’re expecting experiments you can repurpose all year round.
If you’re choosing between a seasonal “activity calendar” and a more open-ended lab-style kit, this one leans into structure: day-by-day learning with built-in materials.
