My son is fond of encyclopedias, and he reads them almost every day.
From time to time he comes to me and tell the most interesting facts he has discovered.
Yesterday he came to me with a great desire to test himself and compare his speed with a cheetah!;))
What a crazy idea! But the thing is this experiment was proposed in one of his Nature books:)
They proposed to test what distance a kid would run for 10 sec.
This result should be multiply for 6, and then for 60 - we get distance that a kid can run for 1 hours.
If we divide it into 1000, we can get his own speed in km/hour.
And then we can compare the result with different animals.
When a kid see just numbers in the book, we can hardly imagine what it means in reality, and whether it's really fast or slow.
When he can try it by himself, it works the best, and thus all numbers are transformed into real and useful info than can be remembered easily.
So these book authors have given a brilliant experiment for kids, an d we have tried it;)
So Vlad ran 37m for 10 sec
That's what we've got:
So we've got 13,3 km/h - his own speed:)
And...a cheetah can run up to 100 km/h
a hare - 70 km/h
a kangaroo - 40 km/h
It was a cool and funny test! Now Vlad knows what speed is;)
