‘Science and Nature’
As winter hits many parts of the world, it becomes cold enough to freeze water into ice. When lakes freeze, the ice usually comes out white because it’s full of little air bubbles. But some hikers in Slovakia came to a frozen lake that was unlike any they had seen before. Read on to find out what was so cool – or cold – about this lake, and do the math!
Today is Christmas Day, when Christians everywhere celebrate the birth of Jesus. A big part of that is decorating the Christmas tree. The Lego store in Sydney, Australia decided to take it a step further and not only decorate a tree, but create one – entirely from Legos! Read on to do the math on this Lego-tastic Christmas tree.
At this time of year we see a lot of pictures of reindeer, often pulling a sled carrying a big fat guy wearing a red suit. Very often those deer have antlers. It turns out that antlers are the fastest-growing bone of any mammal, growing up to 1 inch per day. And with all Spring and Summer to grow, those antlers can get really big! Read on to do the antler math.
When you look at the flowery blue thing in the photo, what do you guess that it is? Would you believe that it’s not a plant, but an animal — and worse yet, a worm? Read on to learn about the “Christmas tree worm” and do the math!
When you watch squirrels or chipmunks run around your neighborhood, do you ever wonder exactly where they go? How about sharks? They can swim hundreds of miles a day, so it could be hard to follow them. But scientists have been following one shark, named Lydia, using a satellite tracker they put on her. Read on to do the math on the miles Lydia has swum!
Satellites are pieces of equipment that fly high up in space around Earth. They send us our phone calls and pictures that show up on the computer; they show us where we are on the map (GPS); and they can study the stars and other stuff out in space. You’d be surprised just how many are flying miles above our heads, and how different they are from each other.
Have you ever rowed a boat using oars? The more you paddle the same way over and over, and the more closely you match the timing of other rowers on your boat, the faster the boat goes. A photographer showed this in beautiful pictures using LED lights. Read more to do the math on this great example of math in action!
Every day, every hair on your head grows. It grows just a little bit, about ½ inch in a whole month, but that’s more than zero. And remember, you have around 100,000 hairs on your head, so the feet of hair can quickly get out of hand!
When you fling yourself into a pile of leaves, do you ever wonder how many leaves are in there? You might be surprised at how quickly the number of leaves pile up.
One of the most fun things about numbers is the patterns they make. It’s even more fun when the number patterns can be found in nature, like Fibonacci numbers. Read on to find out about the Fibonacci pattern and celebrate Fibonacci Day today!
