Carefully review the general safety advice in the instruction book before starting the experiment.
Disassemble the setup after the experiment.
The connector lets you join different devices to the solar battery, such as an LED. Solar batteries are usually placed on similar holders or roofs so that they are oriented to face the Sun.
When you orient the solar battery in the direction of the window, you can watch as it starts to produce electricity. The electric energy it produces powers the LED!
The buzzer lets you know when the most power is generated. How should you position your solar battery placed so the buzzer beeps the loudest?
Dispose of solid waste together with household garbage.
Energy can move from one object to another, like when energy from wind is transferred to a wind turbine’s blades. Energy can also change from one form to another.
Light carries energy . Objects can absorb light and convert its energy into heat. This is why you physically feel sunshine as warmth. Asphalt and sand heat up in the summer because they absorb light energy !
But some materials convert light energy not just to heat, but to electrical energy . These materials are used to make solar panel . They catch the light coming from the Sun and produce electric current. This current holds electrical energy and can make the buzzer beep.
The more light hitting the solar panel , the more energy can be produced. That’s why we rotate solar panels to follow the Sun’s movement during the day. Sunflowers follow the Sun in the same manner. They use solar power for their own needs!

Kids are now able to engage with science in a way that they simply wouldn’t have been able to in the past as they shrink themselves down to see the world at a molecular level
