Sntieecr Fruit Battery Experiment Kit, Lemon Science Kit for Children Science Proiect, Physics Teaching Experiment Package Including: 1 x Instruction 5 x Copper Sheet (4.1cm) 5 x Zinc Sheet (4.1cm) 2 x RGB LED (2.7cm) 1 x RED LED (2.7cm) 5 x Wires (21.5cm) 2 x Wires With Clip (22.9cm) 1 x Electronic Clock (2.9 cm (L)x 0.4m (H) 1 x Buzzer Sounder (2.75 cm (l)x 1cm (H) 1 x Propeller Fan (7cm (L)X 1.5cm(H)) 1 x DC Motor (2.1cm (L) x 3.5 cm (H)) Warm Tips: The voltage that can be generated with copper and zinc tablets varies from fruit to fruit since different fruits contain different concentrations of fruit acids. We prefer to recommend that you experimenting with fruits that are more acidic, such as lemons, or juicier, such as tomatoes! The longer of the LED diodes is positive, the shorter is negative, please ensure that there is no mixing of positive and negative poles before you start the experiment, It is recommended to use 4 groups of fruits in low light places for experiments, 4 groups of fruits can generate 3.5V voltage, which can make the LED light up. Electronic Clocks: It is recommended to use 2 groups of fruits for the Electronic Clocks experiment, 2 groups of fruits generate about 1.6 volts, which can make the electronic clock work properly, if 3 groups of fruits are used, then the voltage generate is larger, and the electronic clock will display the wrong time: 18:88, while using 1 group of fruits, the voltage will be too small, not enough to make the electronic clock display the time WARNING: CHOKING HAZARD-Small parts. Not for children under 3 years. Be careful of scald caused by short circuit. The kids must use under the supervision of adults. If there is any problem with the product you received, please contact us at the first time, we will provide you with a satisfactory solution!
Fruit Battery Kit: Comes with 5 x copper sheet, 5 x zinc sheet,1 x electronic clock, 2 x RGB LED,1 x RED LED, 5 x wires, 2 x wires with clip,1 x buzzer sounder, 1 x propeller fan, 1 x dc motor, 1 x instruction, good kit for your kids DIY STEM science project Fruit Science Kits for Children: The product fan with a faster motor represents a stronger voltage, which can cultivate children's observation ability. The different bright lights and the sound level of the buzzer are also suitable for classroom scientific power generation experiments Fruit Battery Application: Through interesting fruit battery scientific experiments, parents can accompany your children to play and cultivate their science learning interest. Improve children's ability to do things on their own, develop children's imagination and creativity Easy to Operate: It is easy to use in scientific projects. Before operation, you only need to prepare lemons, apples or some vegetables and beverages to assemble the battery. We provide simple experimental ideas. Please kindly see the circuit combination on our pictures and avoid short circuit Warm Notice: Suitable for 8+ years. Be careful of scald caused by short circuit. Do not mix old and new batteries. Do not mix alkaline, standard (carbon-zinc), or rechargeable batteries, the kids must use under the supervision of adults
