We all like different music from each other. You and your friend might like some of the same songs, but not every song, and your parents definitely don’t like all the same songs as you. So what about cows: do cows all like the same music? And is there one kind they like best? Scientists studied this a few years ago by playing different songs for cows to see if the cows made more milk during certain songs. They found that when listening to songs with fewer than 100 beats a minute – maybe about 1 beat per second – the cows gave 3% more milk: in the time the farmers normally got 100 cups from them, they now got an extra 3 cups. Even though people have been studying this since the 1930’s, no one’s sure whether music really makes cows make more milk – or more importantly, whether the milk tastes better.
National Cow Appreciation Day is our big chance to show some love for these sweet, wide-eyed animals. And when you think about how much milk they make in a day, they deserve a lot of appreciation! Read on to get mooo-ving with the cow math.
Today we’re visiting either the 39th or the 40th state to join our country: North Dakota! We don’t know whether North or South Dakota became a state first. The President at the time, Benjamin Harrison, didn’t want either state bragging about being first, the way your older sibling might. So he shuffled the certificates that made them […]
When people fly into the U.S. with their pets, the animals have to stay at the airport for a few days to make sure they’re healthy. And now one airport has begun building a place where the pets can stay in style! Read on to find out about all the special treats these pets get, and do the flying, furry-friend math.
