Troy, A good tip to keep the kids interested is to have a list of stars with the light year distance from the earth. Sirius 8.58. Rigil Kent 4.37. Alpha Centauri 4.37. Caster 52. etc. Find the ones that are the kids, mum, dad. grandparents age and explain to them that the light they are seeing right now started it's journey when they were born.
