‘Science and Nature’
It’s great when a building can weave around the law by using math! That’s just what one new building in Vienna, Austria is doing by taking on a crazy shape. Read on to do the math on how this building is shaping up – or rather, around!
When you look at the sun, you’re actually looking at a star. The teeny prickpoints of light you see at night are stars, too, just really, really far away — and many of them have planets like Earth spinning around them. This week, astronomers found the oldest star we’ve ever seen that has planets. Read on to see how the planetary numbers add up – and if we have new alien friends 690 trillion miles away!
What happens when you toss an ice cube in your glass of juice or water? Does it sink or float? It floats, because an ice cube weighs a little less than the same chunk of melted water. Out in the ocean very far north and south it gets even more exciting, because giant chunks of ice break off from the land and float in the waves. Read on to see why one of these giant chunks of ice is especially awesome – and do the “cool” math!
Have you ever driven by a building with a big black rectangle strapped to it to face the sun? That’s a solar panel, and it turns sunlight into electricity. A panel can run only a few light bulbs, but someone has built a whole airplane that can run its engines on nothing but sunlight. Read on to do the math on this amazing airplane.
Imagine a place that is always colder than your freezer, or than the coldest day you’ve probably ever felt yourself. For whatever reason, some people like to live in places like this. The coldest town on Earth is Oymyakon, Russia, home to 500 people. Read on to find out just how cold it gets there, and do the math on these freezing temperatures!
Has anyone actually tried to dig to China? We know our planet Earth is a ball, so if you’re on one side and just dig straight through, you’d end up on the other side, right? Well, in 1970 a drill in Kola, Russia started drilling straight down into the ground. Read on to see how far down they got and dig deep into hole math!
Next time you walk through a park, imagine that it’s actually covered with water and you’re swimming over it. That’s what happens every year at a lake called Grüner See in Austria. Read on to see just how much rain it takes to make this actual water park – and do the math!
When we get lots and lots of snow, you don’t have to stop at building a snowman. You can make giant snow animals that are taller than you are and as wide as a house, like the Bartz brothers have done for the past 3 years. This year they’ve done it again, and created a giant sea turtle. At 37 feet long and 12 feet tall, the snow and math in this sculpture really piled up! Read on to do the snow sculpture math.
If you’ve ever looked at yourself in the mirror, then looked at a dog, rabbit or (hopefully not in your house) a crocodile, you’ll see that you all have different teeth. Different animals like to munch on different foods, so they need teeth that do the job well. Read on to dig your teeth into the tooth truth!
Today is “National Cut Your Energy Costs” Day, the day when we think about using less electricity in our homes, gasoline in our cars, and other forms of energy. Do you know what things in your house use the most energy? Read on to find out and celebrate the day by doing energy-saving math!
