    Our fastest rockets travel at about 30 000 an hour.
    Use a spreadsheet to work out how far light travels in an hour? In a day? In a year? Post it here.
    cameron Greytown*Greytown
    The speed of light is 299, 792, 458 metres per second (check it on google, it's easy to find)
    So it would mean that it travels 670, 616, 629.4 miles per hour
    983, 571, 056.4 feet per second
    186, 282, 397 miles per second
    And finally, 300 000 kilometres every second!thats crazy

    I learnt that there is only 50 billion air molecles for each person alive today. This may seem alot but since we breath in about 288,886.5 molecules in each breath its not much at all.

    Think about.
    There are more molecules in a glass of water than there are glasses of water in the sea. Share this at home.

    htmldiff3When we as humans are resting we pump about 4 litres of blood a minute. But when we run or do exercise of any sort it can raise to 27 litres of blood per minute. This means that we pump an average of 32 million litres of blood in a 70 year life time. A heart of a rat only pumps 0.05 litres of blood every minute. A rabbits heart pumps at 0.5 of blood a minute and a heart of a hosre pumps 20 litres of blood a minute {these are all when animals are resting.}
