Have you heard that rhyme, “Hey diddle diddle, the cat and the fiddle, the cow jumped over the moon”? Why a cow? It’s a weird idea, since cows aren’t the best jumpers…all kinds of animals jump a lot better. Red kangaroos are the fastest jumpers, leaping 30 to 40 feet at a time at over 30 miles an hour. The hare, a cousin of the rabbit, can zoom at 35 miles per hour and can leap 10 feet — incredible for its size. Some tree frogs can jump 20 times their length. But wait: the annoying flea is only about 1/16th inch long, but it can jump 13 inches, over 100 times its body length! None of these animals can jump 240,000 miles to the moon, but they all have a better shot than the cow.

*Wee ones:* Who jumps farther, the hare that leaps 10 feet or the kangaroo that leaps 30 feet?

*Little kids:* If a kangaroo can jump 30 feet, how many 10-foot jumps does the little hare have to do to match? *Bonus:* If the kangaroo makes 2 leaps, how many jumps does the hare have to make to keep up?

*Big kids:* If you jumped 10 times YOUR height, how far would that be in inches? (Try rounding it off to feet, too, or measuring yourself!) *Bonus:* If a 1/8th inch flea jumps 13 inches, how many times its body length can it jump? (*Hint if needed:* How many times its length does it jump for each inch?)

Answers:

*Wee ones:* The kangaroo jumps farther.

*Little kids:* 3 jumps. *Bonus:* 6 jumps.

*Big kids:* Different for everyone…take your own height in feet or inches, and multiply by 10. *Bonus:* 104 times its body length.
