Kids can build working models or perform experiments in their own science lab with the Clip Circuit science kits for kids These entertaining and educational science kits include components that clip together to make electrical circuits, so there is no need for the mess and danger of soldering Toys in this range include basic lab kits as well as functioning model vehicles. Kids as young as seven can get in on the action here with a colour-coded starter lab kit that includes 14 experiments for making electrical circuits. Other lab toys include a "Noisy Lab" for making circuits with electrical noise makers and the exciting "ElectroLab" version that includes 80 experiments for even more variations on circuit building action with flashing lights, buzzers and more The clip-together fun doesn't end there Kids can also enjoy making models with working electrical components such as an airboat, Helica car, or an Intellirover. The model pieces clip together, so you don't need tools or a soldering iron to make the circuits that power the models Teachers can use these science kits in the classroom for a fun "hands on" lesson that will get kids enthusiastic about science Kids will learn and explore the wonders of electricity and stay engaged in building models that move around or clipping the lab kit pieces together in various ways. Clip Circuit science kit toys are just what you're looking for to keep your older child entertained and learning during the summer holidays They also make awesome Christmas gifts for grandchildren, nephews and nieces to encourage an early interest in electrical engineering or Physics.
