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.

Egg-streme Equinox

So March 20 is pretty special, and not just because it’s the 79th day of the year. In most years March 20 is the start of spring, also called the vernal equinox. Equinox comes from the Latin words for “equal night,” because on this day Earth is tilted perfectly so every spot on the planet has 12 hours of both day and night. Because of that perfect tilt, people try to balance an egg on end at the exact moment of the equinox. Does that actually work? It does – because you can balance an egg  any time! And, as noted in this week’s family activity on our Add It Up blog, eggs are also incredibly strong. While they break easily if they fall sideways onto the floor, they hold up surprisingly well when you press in on them. Take a couple of small plastic cups, stack your egg between them as shown here, and try balancing lots of heavy objects…you’ll find your egg can stand up to a lot.

A Day for Wishes and Tricks

It’s St. Patrick’s Day, that Irish holiday when we wear green clothes, eat green food, and maybe score some “luck of the Irish” for ourselves. There are leprechauns, those funny elf-like fellows from Irish fairy tales who are only as tall as kids, but have big magical powers. Supposedly they keep all their coins in a pot of gold at the end of a rainbow, which would be a great thing to find. It’s even better to find the leprechaun himself, because if you capture him he’ll grant you 3 wishes. Another Irish symbol is the shamrock, or 3-leaf clover, because long ago people in Ireland believed that carrying a clover kept you safe from evil spirits. It’s still a sign of good luck today, and 4-leaf clovers are even better luck. Who knows, maybe today you’ll find a leprechaun or a clover – or at the least, you’ll get to eat a green pretzel.
