What is light?

What to do with this activity?

What is light? Watch the video above to find out - it's from the Royal Observatory in Greenwich near London. 

Light isn't just what we can see - visible light is in the same family as radio waves, x-rays, microwaves and more. We call the whole family the electro-magnetic spectrum. We can represent light as a wave, with a length, frequency and speed. Different colours are simply different wave lengths.

And did you know that light is the fastest thing in the universe? Your child may not understand everything in the video, but it's likely to fire their imagination and curiosity.

  • Why am I doing this?

    Writing is like a muscle – the more your child practises it the stronger their writing ability will become. Your child is also more likely to write about things they like or are interested in – writing is a way to express yourself and using writing in this way can be more meaningful to a child. Word searches and crosswords can help with pattern recognition and spelling, and help build vocabulary and spelling.

  • How can I do more?

    Give your child lots of opportunities to write - notes, birthday cards, emails or text messages. Encourage your child to make and write their own books about something they are interested in, for example, cars, dinosaurs, fairies or dogs. They can draw or stick in their own pictures.
