How Electricity Works

1. Energy Power Up! – Find out more about batteries and mains electricity, with activities and quizzes.
2. Who Can Resist – Online experiment to test different substances to see if they conduct electricity.
3. Electronics- A good introduction to electronics. (Scroll down and click on topics under “Components/Symbols” and “Component and Circuit Details”.)
4. Making Circuits - Analyze why some light bulb, battery, and wire combinations will work and why others will not.
5. The Path of Electrons – Students engage in an interactive “hot potato” demonstration to gain an appreciation for the flow of electrons through a circuit. They role play the different parts of a simple circuit and send small items representing electrons (paper or candy pieces) through the circuit. Students describe the functions of a switch and light bulb as resistors in a circuit and list several products that have been engineered to use electrical energy.
6. BBC Bitesize Science – Find out about circuit symbols (scroll down the webpage) then build electrical circuits at the following website.
7. Circut World – Build and test electrical circuits.
8. BBC Bitesize Science - Find out more about resistance, Ohm’s Law and resistors, with animations and test-yourself mini-quizzes.
9. Molecular Expressions- Interactive activities about resistance.
10. Electrical Conductors – Fun online activities about electrical conductors and insulators.
11. Science and Safety of Electricity – Click on “Fire in the Sky” for lightning facts.
12. You’ve got the Power – Electricity in the smart home.
13. Electric Blues - Students brainstorm a comprehensive list of electrical devices typically found in their homes. They then create public service announcements advocating energy conservation to present in class and to the school.
14. American Experiment – Animated diagram of a battery.
15. Franklin’s Lightning Laboratory – Try some fun electricity experiments.
16. Take Charge - Students induce an electrical charge on various objects, and experiment with electrical repulsion and attraction. They define related vocabulary, play Bingo and complete a take-home quiz.
17. National Geographic Kids - Watch a video clip about lightning.
