In design futures lesson today l learnt about light as we are making lamps. I found out that light years means how far away the star or planet is. For example if a star explodes but it is 130 light years away then we would only on earth see it 130 years later! This lesson was actually really interesting and I enjoyed it and was engaged in the things we were learning about light! here are some examples of light. even though you can't see it or touch it, you can see the effects of it :)
