Thames & Kosmos CHEM C1000 vs hand2mind Dig & Display Fossil Kit
Which should you buy? Our verdict on both, pulled from our full The Best Kids Science Kits: 4 Compared (and One to Skip) comparison.
The CHEM C1000 is the real chemistry set: 125 experiments with proper equipment. The hand2mind fossil dig delivers 8 real fossils plus a display case. KiwiCo's crates are the it-depends subscription gift that keeps arriving. Skip the slime-themed kit: it is a slime craft set sold at science-kit prices.

Thames & Kosmos CHEM C1000
Buy itThe real chemistry set: 125 experiments with lab equipment, chemicals and a full-color manual.
- 125 experiments spanning indicators, chromatography, air pressure, electrolysis, crystals, metals and kitchen chemistry: a real course in a box.
- Lab equipment and real chemicals in the box, and the electrolysis experiments need a battery you supply.
- The manual teaches lab setup, safety and technique first, so a kid learns to do science, not just watch reactions.
- Mid-range money for the scale of content.
- Real chemistry means real supervision: Thames & Kosmos rates it 10 and up, and younger kids need an adult at the bench.
- Some supplies are consumables; the kit runs out of a few reagents with heavy use.
- This SKU is marked not for sale in Canada, so check availability outside the US.

hand2mind Dig & Display Fossil Kit
Buy itDig 8 real fossils, shark tooth, crinoid, petrified wood, coprolite among them, out of a block and mount them in a museum-style display.
- 8 real fossils in the digging block: shark tooth, crinoid, bivalve, atrypa, petrified wood, coprolite and two kinds of gastropod, not plastic replicas.
- The packaging converts into a display case, so the kit ends with a shelf-worthy collection.
- The Mission Guide teaches land-versus-sea origins, observation and prehistoric Earth: real geology, not just digging.
- Budget tier for the cheapest real-science content here, with two digging tools in the box.
- It's a one-session experience: dig once, done. The display is the lasting value.
- Digging is messy, dust and plaster on the kitchen table; do it over a tray or outside.
- The fossils are real but small; the display case is the wow factor, not specimen size.
