In this experiment, students create a chemical battery with a lemon that is able to power a small light.
This could be an effective demonstration for younger classes, or a great hands on activity for students completing the year 6 electricity unit.
Investigate the transfer and transformation of energy in electrical circuits, including the role of circuit components, insulators and conductors

Examine why advances in science are often the result of collaboration or build on the work of others
Pose investigable questions to identify patterns and test relationships and make reasoned predictions
Pose questions to explore observed patterns and relationships and make predictions based on observations
Use equipment to observe, measure and record data with reasonable precision, using digital tools as appropriate
Construct and use appropriate representations, including tables, graphs and visual or physical models, to organise and process data and information and describe patterns, trends and relationships
Compare observations with predictions and others’ observations, consider if investigations are fair and identify further questions with guidance

Electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources
With guidance, identify questions in familiar contexts that can be investigated scientifically and make predictions based on prior knowledge
Science involves testing predictions by gathering data and using evidence to develop explanations of events and phenomena and reflects historical and cultural contributions
Compare observations with those of others
With guidance, pose clarifying questions and make predictions about scientific investigations
Decide variables to be changed and measured in fair tests, and observe measure and record data with accuracy using digital technologies as appropriate
Science involves observing, asking questions about, and describing changes in, objects and events
Compare data with predictions and use as evidence in developing explanations

Plans and uses materials, tools and equipment to develop solutions for a need or opportunity
Plans and conducts scientific investigations to answer testable questions, and collects and summarises data to communicate conclusions
Energy from a variety of sources can be used to generate electricity; electric circuits enable this energy to be transferred to another place and then to be transformed into another form of energy
Compare results with predictions, suggesting possible reasons for findings
With guidance, identify questions in familiar contexts that can be investigated scientifically and predict what might happen based on prior knowledge
