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.

On the Other Hand…

Most people are right-handed, which means they use their right hand to write and generally feel stronger using their right side.  However, there are people out there who are left-handed, which means that they write with their left hand, and probably pour drinks, brush their hair, and do lots of other things lefty.  In the old days, everyone thought left-handed people were a threat to society.  But don’t worry, now that we have Google to look up all this stuff, we know that being lefty isn’t bad at all.  In fact, it might mean you’re better at certain things, like music and math.  You will, however, have to get a different-shaped glove to play catch.

Do you like ketchup on your burger, fries, or hot dog? We’re loving this robot that squirts the ketchup for you. But it doesn’t seem to do the math right on the timing, making a big, ketchup-y mess. Read on to “mustard” up the math in this ketchup-squirting robot!

Going to the post office may seem like just another daily job. But not when you work at the post office in Antarctica, where you get to take care of penguins, too! Read on to see just how many people want to work there – and get a little silly with the penguin post office math.

You’ve heard of birds and planes flying. But what about toilets? One group decided to create a portapotty rocket and make it fly! Read on to get carried away with the numbers in this rocketing restroom.

Have you ever really looked at your clothes up close? If you did, you may have seen that they’re made up of lots of smaller threads weaved or knitted together. The patterns in weaving and knitting require a lot of math! Read on to get up “clothes” and personal with the math and numbers in your shirts.

Reading a Book to Fluffy

It’s fun to read a story, so why shouldn’t cats get to hear a bedtime story like we do? One animal shelter thought they should, and created a Book Buddies Program where kids come and read to the cats there. When you count up all the kids, cats, and books, the numbers really add up! Read on to find out more about this meow-gnificent idea.

Now this is silly: a dog eating at a table, using human hands! One man taught his dog Mariele this funny trick, and they put on shows for people. When you think about the practice this must have taken and all the food to practice it, the numbers really begin to wrack up. Read on to do the math about this fine-dining dog.

When you go to the post office, you can mail lots of different things just by putting them in a box and putting stamps on them. But at one post office in Hawaii, you can smack some stamps right on a coconut and send it to a friend – no box required! Read on to see how the postage and fun add up when you go nuts mailing coconuts.
