In places with lots of farms, it can be tricky to keep crops and farm animals safe from wild animals, while still letting those wild animals live. For once, we can solve both problems at the same time. Click “Read More” to see how poison apples are doing this – and do the math!
No matter how much you love pet fish, there’s a limit as to how many you can have. The rule is 1 gallon of water for every 1 inch of fish. So if you want more fish, you have to build a bigger fish tank, like this one guy did. Click “Read More” to see just how big this tank is and do the fishy math!
Usually, storms like tornadoes and hurricanes twirl in circles. But this storm on Saturn that has probably been raging for centuries is different. Click “Read More” to find out why and do the stormy math!
We all know that soda is loaded with sugar, rots people’s teeth and makes people fat if they drink too much. So it’s not surprising what’s left when one guy boils a bottle of soda. Click “Read More” to see how the math in all this boils out!
Palm trees are those tall, skinny plants with the spiky green pom-pom tops, often swaying in the breeze near some beautiful blue ocean. As cute and perky as these trees look, palm leaves can grow more than 75 feet long and over 10 feet wide! Click “Read More” to see how these tall giants stack up, and do the math.
The bat is a strange, spooky animal. It looks like a mouse with spiky wings, and makes squeaky sounds to find the food it’s hunting down to eat. The biggest, most alarming crowd of these might be the Congress Avenue Bridge bats in Austin, Texas, with more than 1 1/2 million bats. Click “Read More” to find out what’s so good about these animals – and do the batty math!
The green anaconda is by far the biggest snake in the world. It’s the heaviest, the thickest, and also the second longest, outdone only by the python. Click “Read More” to do the slimey math on this snake!
Flying people to Mars won’t be easy. They’ll have to fly on a 3-year, 60-million mile trip to the right place, and then land on the ground safely. With the air so thin on Mars, you can’t land a spacecraft like you would an airplane. So NASA’s improvising. Click “Read More” to find out how, and do the math!
We know birds migrate, meaning they travel to cool places during the summer, then back to warmer places to spend the winter. What’s incredible is how fast that flying can add up for even the tiniest bird. Click “Read More” to do the math on how one bird has really racked up the frequent flyer miles!
On this day in 1876, Alexander Graham Bell finally got his invention working: the telephone. It worked nothing like our phones today: the very first phones were sold in pairs, where each phone could call only that one other phone (you had to pick that other person carefully). Then came the “switchboard,” which let you call any other phone, but the “operator,” a phone company person in the middle of town, had to plug in wires to connect your call for you. Now we can call anyone anywhere on our own within seconds, and through the air. But that first phone, that first time talking to someone through a wire, must have looked like magic.
