‘Vehicles and Transportation’
Did you ever wonder what cars would say if they could talk? Chances are they’d ask a lot of questions that you’d be able to answer by doing some math. So read on to see what your car might say…and figure out how you’d answer it!
Have you ever watched an airplane in the sky, and wondered how many people are in there, and where they’re going? Now just imagine how many planes fly above you in one day! Read on to take flight with the math in the number of people flying over your head.
When we drive on the road, we can’t all just go every which way. We have to stay on one side, and wait our turn where roads cross. Stop signs help, but really busy crossings need traffic lights. The traffic light, that cute red, yellow and green trio, was patented (made official as an invention) on this day in 1923. Actually, the very first electric traffic light was invented in 1912 by Lester Wire, a policeman in Utah fed up with all the traffic; you can imagine, after hundreds of years of slow horse-drawn carriages, what it was like to have this speedy, loud thing called a car suddenly show up. So Wire borrowed the idea of railroad signals to make a traffic light, which had just red and green for stop and go. Then in 1920, Detroit cop William Potts built one with 3 colors (red, orange and green). As you see here, people have tried other designs, like this funny dial one from Australia, but the three-color light is what keeps most of us from crashing into each other today.
As beautiful as a rose is, a dozen is even more beautiful. So how about 18 million of them, put together to make all kinds of shapes of animals, buildings, people, and more? Read on to wake up and smell the roses – and do the math in the annual Rose Parade!
Balloons come in lots of different colors and shapes, and float all around the place, which make them lots of fun. But making a shape with them to break a world record make them even more exciting! Read on to see how many balloons were needed to break this world record – and get carried away with the balloon math.
Sometimes people make a wrong turn while driving. But imagine taking a wrong turn while flying a plane! Read on to fly through the math on one pilot who took a very wrong turn, which earned him the nickname “Wrong Way” Corrigan.
Drones don’t have to be used just for flying. Read on to see how they can help make Thanksgiving dinner, and fly through the messy math of cooking with a drone!
Bridges are neat structures that help us get across water. And this bridge in Midland, Michigan is especially cool because it’s a 3-way bridge! Read on to triple the math fun with this bonkers (and awesome) bridge.
Next time you drive under a bridge or overpass, look for a sign on the side with numbers on it. It will tell you the bridge’s height above the road in inches and feet. Why? So we don’t have what happened in this picture!
What do you do when you can’t break a weight world-record with your 1,100-pound pumpkin? You row it, of course! Read on to paddle through the math in this crazy world record.
