Educational kit: Water
Research set “Water” for primary school: 29 items for 10 experiments - water purification, dissolution, buoyancy, liquid pressure.
A primary school science kit for investigating water, with 29 equipment items and 10 experiments. Children purify water through multi-stage filtration, investigate soluble and insoluble substances, separate mixtures by filtration, and study buoyancy, the force of flowing water using a water wheel model, and pressure within a liquid. A submarine model demonstrates diving and surfacing. The kit includes a water purification device, filter materials (granite chips, quartz sand and activated carbon), a water wheel model, a liquid pressure measuring device, reservoirs and laboratory stand components.
