Climate change and electricity? Investigate types of circuit with buzzers and lights to experiment and find out which is best for our planet. In this science activity for Key Stage 2, students will investigate different types of circuits to determine the most sustainable ones. They will then build their own Christmas lights by making a circuit with LED bulbs and crocodile leads. This is an engaging experiment that will encourage students to have fun with science! Students will first compare series circuits against parallel circuits. A series circuit is a configuration where components are connected one after another in a single path, creating a single flow of current. In contrast, a parallel circuit is a setup where components are linked across multiple paths, allowing current to split and flow through each component independently. Following this, students will replace the battery pack in their circuit with a solar panel. Students should consider the following questions: Are the LEDs as bright as with the battery pack? How does the weather affect the brightness of the LEDs? Can you add as many LEDs to your parallel circuit as you can with the battery pack? Solar power is a renewable energy source that is much better for our environment. In this activity, we use solar panels, which transfer solar energy into electrical energy and light energy without storing it. Solar panels aren’t useful for Christmas lights as it would mean that they would only work during the day if the solar panel were in direct sunlight. In order to use our Christmas lights at night, we would need to add a storage cell, such as a rechargeable battery, which could store the energy until we turn on the lights in the evening. We would still need to ensure that the solar panel is in direct sunlight during the day, though, to ensure our lights come on every evening. Next time you buy your Christmas lights, think about what you could do differently to help protect our environment, particularly Santa’s North Pole! Equipment required A 2 x AA battery pack and batteries A 3V solar panel At least eight crocodile leads At least 4 LEDs (Different colours if possible) 5V bulb to show the difference in light emitted Download the free Build your own Christmas lights activity sheet!
