Thames & Kosmos Chem C1000 Chemistry Set - 125 Experiments

125 Real Chemistry Experiments. Real Lab Equipment. Real Science. — Thames Kosmos Chem C1000

The Thames Kosmos Chem C1000 is a comprehensive home chemistry set covering 125 experiments across a broad range of chemical concepts — acids and bases, indicators, chemical reactions, crystallisation, electrochemistry, and more. The kit includes real laboratory equipment (test tubes, beakers, measuring tools, a lab stand) and the chemicals needed to conduct the experiments, along with a full-colour experiment manual that guides each investigation with clear instructions and explains the chemistry behind what’s happening. This is a serious chemistry set for children who want to do more than watch things fizz — it’s designed for methodical investigation and genuine chemistry learning. Ages 10+.

What the Kit Covers

The 125 experiments are organised progressively, beginning with foundational chemistry concepts and advancing to more complex investigations. Topics covered include:

• 🧪 Acids and bases — pH testing, neutralisation reactions, the chemistry of everyday acidic and alkaline substances
• 🌡️ Chemical indicators — natural and synthetic indicators that change colour in response to pH; making your own indicators from plant sources
• 💧 Chemical reactions — observing exothermic and endothermic reactions, precipitation, gas production, and colour changes that signal a chemical change has occurred
• 🔬 Crystallisation — growing crystals from supersaturated solutions; investigating how temperature and concentration affect crystal formation and size
• ⚡ Electrochemistry — simple electrolysis experiments demonstrating how electrical current drives chemical reactions and separates compounds
• 🧴 Filtration and separation — physical and chemical methods for separating mixtures; chromatography and distillation concepts

What’s in the Kit

• ✅ Laboratory equipment — test tubes, beakers, measuring tools, lab stand, and accessories for conducting experiments
• ✅ Chemicals and reagents — the substances needed to conduct the 125 experiments; carefully selected for safe home use
• ✅ Full-colour experiment manual — step-by-step instructions for all 125 experiments with explanations of the underlying chemistry

Why This Kit Is Different from Simpler Chemistry Sets

• ✅ 125 experiments is a genuine curriculum, not a collection of tricks — simpler chemistry sets offer 10–20 experiments, most of which are variations on baking soda and vinegar reactions; Chem C1000’s 125 experiments span multiple chemistry topics and progress in complexity; a child who works through the full set will have covered the equivalent of a school chemistry curriculum in practical terms
• ␅ Real lab equipment, not toy apparatus — the kit includes actual laboratory glassware and equipment (not plastic “pretend” versions); this is a meaningful distinction for older children who are ready to treat chemistry seriously; the equipment is what makes the experiments replicable and accurate
• ✅ The manual explains why, not just how — each experiment includes an explanation of the chemical principles at work; children don’t just follow steps and observe an outcome — they learn what’s actually happening at a molecular level; this is the difference between a science toy and a science education tool
• ␅ Thames Kosmos is the benchmark for serious home science kits — Thames Kosmos has been producing science education kits for decades and their chemistry sets are consistently recommended by educators; the Chem C1000 is their mid-range chemistry set, positioned above the introductory Ooze Labs range and below the advanced Chem C3000

Frequently Asked Questions

What age is this best for?

Recommended from age 10. The Chem C1000 is a substantive chemistry set with 125 progressive experiments — it’s designed for children who are ready to work methodically through a manual and conduct experiments with care. Children aged 10–14 get the most from it, particularly those who are curious about chemistry at school and want to explore further at home. Adult supervision is recommended, particularly when working with chemicals for the first time.

Is adult supervision required?

Adult supervision is strongly recommended, particularly for children at the younger end of the age range and when conducting experiments with chemicals for the first time. The chemicals included are selected for safe home use, but chemistry experiments should always be conducted with appropriate care — reading instructions before starting, working in a clear space, and having an adult present or nearby.

How does it compare to the Thames Kosmos Ooze Labs Chemistry Station?

The Thames Kosmos Ooze Labs Chemistry Station is Thames Kosmos’ introductory chemistry set — designed for younger children (age 5+), with a smaller number of experiments focused on visual, sensory reactions (slime, colour changes, fizzing). The Chem C1000 is a more advanced set for older children (10+) with 125 experiments across a genuine chemistry curriculum. If a child is new to chemistry or under 10, start with Ooze Labs. If they’re ready for real lab work and systematic investigation, Chem C1000 is the right choice.

Is it a good gift?

Yes — it’s a standout gift for science-passionate children aged 10 and up, particularly those who are interested in chemistry at school and want to go further. The 125-experiment scope means it’s not a single-session gift — it’s a kit that gets used across weeks and months as children work through the experiments. A strong birthday or Christmas gift that genuinely advances a child’s scientific understanding rather than just entertaining them once.
