Build a DIY Shake Table Science Project: Test Earthquake Resistance

Hey kids, y’all wanna learn somethin’ about buildin’ stuff that can stand up to an earthquake? Lemme tell ya, back in the old days, we didn’t worry ’bout this kinda thing much, but now it’s real important, specially with all them tall buildin’s they put up nowadays. So today, I’m gonna show ya how to make a “shake table” at home for a science project. This here shake table will help ya see how buildings behave when the ground starts shakin’ like a rattlin’ ol’ truck. It’s like bringin’ a mini earthquake right to your own table! Fun and learnin’ all at once, right?

What’s a Shake Table?

Well, a shake table is just a thing that moves back ‘n forth, side to side, sorta like how the ground does in an earthquake. Scientists and engineers use these tables to test buildings, see? They build models of buildings, then shake ’em on this table to see if they’d fall over in a real earthquake. We ain’t buildin’ no skyscraper today, though! We’re makin’ a small version you can use to test tiny models.

What You’ll Need

Alright, here’s the stuff ya gotta get together to make your shake table. Don’t worry, nothin’ fancy here:

• Two pieces of plywood (one for the base, one for the table top)
• Four wooden blocks (for the table corners)
• Some foam core board or cardboard
• Hollow metal tubes or even straws (for makin’ supports)
• A hot glue gun (careful with this! It’s hot!)
• Two or more rubber bands (these’ll do the shakin’)
• A drill or rubber band puller if ya want it to shake faster

Got all that? Good! Let’s get started buildin’.

Step 1: Build the Base

Lay down one piece of that plywood flat on the table; this is your base. Glue them wooden blocks near each corner – make sure they’re all the same distance from the edges. These blocks’ll help hold up the top piece. But don’t glue the top piece just yet! We need to be able to shake it.

Step 2: Make the Table Top

Now, take the other piece of plywood and place it on top of them wooden blocks. We’re gonna use rubber bands on each side of the plywood, stretchin’ ‘em tight between the two layers. Hook the bands on each side, then twist ’em so the top piece can slide back and forth when you give it a tug.

Step 3: Add Supports (Optional)

If ya got some hollow metal tubes or even plastic straws, you can glue these along the top layer, kinda like fence posts. It gives ya some “walls” so your buildings won’t fall right off the table. Glue ’em firm so they don’t wiggle none.

Step 4: Testing Time!

Alrighty, now the fun part! Find a few lightweight items like tiny blocks or Lego pieces, stack ’em like a building, and set ’em on your table. Then, pull the rubber bands or push the top layer back ‘n forth gently. See how your mini building holds up to the “earthquake”? You can adjust how fast ya shake it to see what it takes to make your building fall.

If ya wanna get fancy, use a drill on a low speed and attach it to one side of the table. This’ll shake it nice ‘n even without ya having to pull by hand. Just don’t go too wild or ya might see your table flyin’ across the room!

What’s the Science Here?

So what’s all this teachin’ ya, huh? Well, when the ground shakes, buildings gotta be strong and balanced to stand up. By usin’ your shake table, you can learn what makes a building stronger or weaker. Engineers build real big shake tables to test skyscrapers and bridges. They need to know if somethin’ is too wobbly so they can fix it. So ya see, you’re kinda doin’ what engineers do, just on a smaller scale.

Ways to Experiment More

Now that ya got your shake table, don’t just stop there! Try buildin’ different types of “buildings” with other materials like paper, Popsicle sticks, or clay. Stack ’em tall or make ’em wide and see which ones are stronger. Try addin’ weight to see how it changes the balance. Testin’ and shakin’ is all about findin’ out what works and what don’t.

Conclusion

Well, there ya have it! A fun little science project that shows ya how buildin’s can handle a good shake. Don’t need no fancy stuff to learn the basics of buildin’ strong structures. All ya need is a few pieces of wood, some rubber bands, and a curious mind! So go on, give it a try, and see how many buildings ya can shake down before ya find one that stands strong.
