## Description

Conduct more than 60 electrifying experiments with circuits and magnetic contraptions. Build series and parallel circuits. Experiment with push buttons and on-off switches. Assemble circuits that include a spinning motor, two switches, and up to three light bulbs. Conduct tests to see which materials are magnetic. Learn about the force of magnetism and magnetic poles. Magnetize a metal. Use iron fillings to make invisible magnetic fields visible. Investigate magnetic force and direction with a magnetic pendulum device. Learn how a compass works and about Earths magnetic fields. Build an electromagnet. Finally, put everything you have learned to good use by constructing a loudspeaker, an electromagnetic relay switch, and a morse code telegraph key. The components are specially designed to make learning fun and accessible. The electrical blocks fit together with simple plug-and-socket connectors. The 64-page, full-color experiment manual guides includes easy-to-follow diagrams.

## Questions & Answers

**Q: would a 13 year old enjoy this kit**
A: If they are already familiar with the concepts it is probably to basic for them. I gave it to my 9 year old and she easily understood it and explored it in her own. She did enjoy it very much and then used some of the parts to turn a homemade solar car into one that used batteries.

**Q: How long does it take to assemble a circuit? Science class is 30 min long. Do you recommend assembling it in advance?**
A: Depends on the circuit.  I’d build several at home and disassemble…and be ready based on the actual project.  It would have to be a fairly simple project to go start to finish and tested in 30 min. IMO.  Good luck! M 😀

**Q: Are replacement manuels available?**
A: Thank you for your question. You can access the digital experiment manual for our Electricity & Magnetism kit here: http://thamesandkosmos.com/manuals/full/620417_electricitymagnetism_manual.pdf

If you wish to have a physical copy of the manual sent to you, please reach out to us at support@thamesandkosmos.com

**Q: Is there any booklet to explain theory ? Make kid understand instead of just following instructions to build**
A: Yes, there’s a booklet that explains the basics.
