Designing and Testing Structures with an Earthquake Shake Table Rubric

Now listen here, my dear, let me tell you a thing or two about this shake table for earthquakes. You see, every time the ground shakes, buildings start to sway. Some stand tall, while others just crumble like an old barn in a storm. So, what we got here is a way to make something called a “shake table.” It’s just a small model to show how buildings react when the earth starts to rumble beneath ’em. And let me tell ya, it’s mighty useful for folks who wanna learn how buildings stand up to quakes, and why some just don’t make it through.

Now, this shake table ain’t some fancy contraption you’d see in a science lab. No sir, it’s something simple that you can build at home, or in a classroom. The best part is it won’t cost ya much, and you can use it to make your own little earthquake right there on your table. All ya need is a few basic materials like Popsicle sticks, toothpicks, rubber bands, and maybe a little motor if you wanna make it really shake, shake, shake.

How to Build Your Shake Table

• Start by gathering some materials – Popsicle sticks, glue, and rubber bands. You’ll also need a base, like a piece of cardboard or wood, to hold everything together.
• Next, you need to decide how big you want your shake table. It don’t need to be too fancy. Just big enough to hold a small structure you wanna test.
• Now, build the frame of the table. You want to make sure it’s sturdy, but don’t go overboard – after all, it’s just a model to show what happens when the ground shakes.
• If you want a motorized table, just attach a small motor under the frame. This motor will make the table shake, simulating an earthquake. You can find these motors in old toys or buy a cheap one online.
• Once you got the frame done, stick your structure on top – could be a building made out of toothpicks, wooden cubes, or anything that’ll stand up to a little shaking.

Now, once you’ve got it all set up, it’s time for the fun part – the shaking! You turn on that motor and watch as your building wobbles around like it’s in a real earthquake. Some buildings will stay strong, while others will just fall apart. It’s a good way to see what kinds of designs work best when the ground gets to shaking.

Why Do Buildings Shake During Earthquakes?

Well, sugar, when the ground shakes, the earth moves, and that makes buildings sway. Some buildings, the good ones, have been built to bend and move with the shaking. They got flexibility built in, like a willow tree that sways but don’t break. But others, the ones that ain’t built so strong, they just crumble, like old crackers in a fire. That’s why we need to test our designs – to see if they’re gonna hold up when things start rumbling.

When you’re using that shake table, you’ll get to see what happens to different types of buildings during an earthquake. You might have a tall building, a short one, or one with a narrow base. Each one is gonna react a little different, and some might survive better than others. This can help you figure out what kinds of materials and designs work best when building something to withstand the big shakes.

Now, don’t go thinking this is just for big scientists and engineers. Oh no, this is something anyone can try, even young folks, to see how the world shakes and why some buildings stay strong. You can build your structure, give it a shake, and learn what works and what don’t. And you can also have a little fun while you’re at it, making your building dance across the table like a leaf in the wind.

What Can You Learn From the Shake Table?

• First off, you’ll see just how much shaking can mess with a building’s stability. Some buildings will sway gently, while others will fall right over.
• Next, you’ll understand how different materials and shapes hold up under pressure. Toothpicks might snap, but thick wooden blocks could stand a better chance.
• Last but not least, you’ll learn the importance of making buildings flexible and strong enough to withstand the shakes. No good having a building that can’t bend a little when the earth moves.

So, there you have it, honey. The shake table is a simple way to see how buildings react during an earthquake. You don’t need to be a big city scientist to make one or use it. Just grab some materials, put together a little structure, and let it shake! It’s a fun, hands-on way to understand the science behind earthquakes, and it might just teach ya a thing or two about building something strong and steady.
