A children's experiment kit should encourage curiosity and create practical learning opportunities. However, almost every set sounds like a complete children's research laboratory in its product description. Parents, grandparents, primary schools and educational institutions should therefore take a closer look at the recommended age, contents and safety information.
Terms such as STEM toy, “laboratory” or “science kit from age 8” do not automatically describe an extensive range of contents. Check which ingredients, tools, moulds and containers are actually included. Some sets require additional household materials. This is not necessarily a disadvantage, but you should be clear about it before buying.
A chemistry experiment kit may contain small parts, essences, powders or steps involving hot water. The age label is therefore an important selection criterion, not just a marketing statement. For sets aimed at children aged 8 and over, plan for direct supervision by an adult, particularly when mixing ingredients, using heat sources or handling substances that may irritate the skin.
Slime, glitter and homemade sweets can have a scientific connection. However, the educational value depends on whether clear instructions explain the processes behind them. Look for step-by-step instructions, background information and tasks involving observation and comparison.
For children aged around 6 to 9, a set with short, clearly structured experiments and illustrated instructions is suitable. According to the product details, the Kosmos Student Lab is designed for 6- to 9-year-olds and covers topics including light and shadow, air and water, as well as the senses.
From the age of 8, more specialised sets may be suitable. These include a DIY perfume-making experiment set, a Slime Lab and a gummy candy laboratory. Check whether the child can already measure safely, follow instructions and tidy up thoroughly after the activity.
A comparison should distinguish between tools that can be used repeatedly and consumable materials. Moulds, measuring cups and workstations can be reused several times, whereas powders, fragrances and gelling agents are generally limited.
The Kosmos 658106 Fun Science – Gummy Candy Lab is listed as including vegan gummy candy mixtures in two flavours, gelling agent, moulds, a measuring cup and four jars with stickers. Water and a heating step are also required for preparation.
Look for the notice “not suitable for children under 36 months” and check for possible small parts. With chemical toys, the instructions must be read and kept for future reference. Fragrances and other ingredients should not be swallowed and may only be used as instructed. Before use, also check the information about possible allergens.
For sets involving hot water or heat, a stable, well-lit work surface is advisable. Food-related experiments should not be carried out next to uncovered food if the instructions rule this out. After every activity, washing hands and cleaning the work surface should be part of the routine.

We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations applicable in the EU.
For children aged 6 and over, manageable experiments involving nature and technology are usually more suitable than chemistry-focused sets. According to the product details, the Kosmos 636111 Student Lab is designed for 6- to 9-year-olds. An adult should still be present and go through the instructions with the child.
This depends on the subject and the individual experiment. Short observation tasks can often be incorporated into a lesson or family activity. Fragrance mixing, slime and gummy sweets also require preparation, setting and cleaning time. Make sure you have a stable work surface and allow plenty of time for tidying up.
Yes, many sets run low on consumable materials after several uses. Before buying, you should therefore distinguish between the ingredients included and the materials needed for later refills. Tools such as measuring cups, moulds and a workstation can be used for longer, depending on the set. The instructions and manufacturer’s information provide details of the intended scope.
