Description
The optic fibre lamp helps showcase how broadband internet works for kids!
When light hits a boundary between two different substances it can bend. This bending of light is also known as refraction. Light can refract when it moves between different materials; glass, plastic, water, air etc. Fibre optics take advantage of total internal refraction, whereby the light is completely refracted within the fibre and can then travel quickly through the fibre with only a small loss of energy.
This property of light is exploited by optic fibre design for use in hi-speed broadband technology, as the light signals can be encoded to send information across the world. This is done by turning on and off light signals in the correct sequence and sending these signals along optic fibres to be received
Teaching ideas for the optic fibre lamp
- Discuss how fibre optics work with your students.
- Light travels incredibly quickly: 299,792,458 metres per second in a vacuum. What speed does it travel in other materials?
- What other communication methods over long distances have people used over the years.
- Learn how light is encoded with information for materials to read.
- Research quantum computing.
- Make a telescope.
School science visit that expands on this science teaching resource
I just wanted to pass on how much the staff and students really enjoyed it and how perfect it was to launch our science week activities. The students were enthralled, educated and entertained – a perfect trifecta!
-Caulfield Grammar School – Big Science Big FunThanks so much for presenting at our school on Monday. Our students enjoyed the show.
-Greenvale Primary School – Big Science Big FunFizzics Education curated a thoughtful and hands-on experience for the children, incorporating practical, skill-based learning activities and followed by a science presentation at the end of the event involving liquid nitrogen. This was delivered safely and effectively, capturing both the children and the parents for the duration of the presentation.
-Macquarie Bank – Family Fun DayFizzics Education ran a show today at our school and it was wonderful. He was a great facilitator and the show was age appropriate and well done.
