Do you know the story of the Brooklyn Bridge? Twenty One Elephants and Still Standing tells the tale of the construction of this famous landmark, and serves as the inspiration for this week’s Architecture and Engineering activity with a fun engineering science for kids challenge.
Can You Build A Bridge for Twenty-One Elephants?
Twenty One Elephants and Still Standing tells the true story of the fourteen year construction of the Brooklyn Bridge, in easy-to-read verse with gorgeous, full page illustrations.

Once the bridge was completed, it linked Brooklyn and New York City. But many were intimidated by its size, worried about its strength and questioned how long it would stand. P.T. Barnum, the creator of ‘The Greatest Show on Earth’, decided to stage a public spectacle to prove the bridge’s integrity. He planned a circus in Brooklyn and marched his elephants, all 21 of them, through Manhattan and across the bridge to Brooklyn!
Engineering Science for Kids Challenge
For our Architecture and Engineering Activity this week, after reading the story, I gave Big M (age 4) a tray full of assorted recyclables and household objects and challenged her to build a bridge for 21 elephants. Our supply set up included the following.
Supplies
Twenty One Elephants and Still Standing
Popsicle craft sticks
Paper towel rolls
Miniature red cups
Learning Resources Jungle Counters
The elephants for our challenge came from a set of jungle-themed counters from Learning Resources… and you might notice, some of our elephants don’t have trunks because they are actually hippos!

I let Big M take the lead on constructing with the materials, and she opted to use the cups and popsicle sticks to build her bridge.
When she could only get 3-4 across, she started building up…
… but found it a little wobbly, and opted for adding lanes instead.
In addition to engineering science, this also made for great counting practice. At age 4, she’s working on counting to and beyond 20. She’s pretty good up to about 15 before she starts to stumble. So we worked on counting all the elephants/hippos every time she added one more. Until, finally – all 21 were in place!

Great activity! Is there a lesson plan that goes with this?
There is no printable or additional instructions, beyond the post, if that’s what you mean?
[…] I got the idea to use this book from: Playground Parkbench! […]

Found this post on Pinterest and it was just what I needed! I am a Girl Scout leader of a troop of girls ages 7-10. We are working on an engineering project so this book was a great thing to read. I was lucky our local library had this book in stock! We read the story and then we then took your idea and expanded on it for older girls. I had them build structures with toothpicks and clay as the bones and popsicle sticks as the floors. We used small square blocks, kind of like legos, to stand in for the elephants. The girls really had to plan and think about what they were going to do. There was a lot of trial and error until they could build something for all 21 “elephants.” Thank you for the great idea!
I’m so glad you liked it. That is an awesome expansion activity for the older girls. I’d love to see pictures if you are willing to share!

Where did you get your blue tray?? I LOVE this so much! Thanks for sharing!
So believe it or not, it’s a Dollar Store appetizer tray – they still have them! Or they have in the past – they work great for almost ALL kids activities. Sorting, craft supplies. My kids love to use them for LEGO too – to sort all the pieces before they start building. Makes for easy clean-up or saving an activity to finish later too.

Did you only allow a certain number of supplies to do the building? I am going to do this with a group & wasn’t sure if you gave them a certain number of cups & sticks.
I didn’t limit it – I just put out an assortment of recyclables and craft materials to build with. My daughter gravitated towards the cups and sticks. But you could certainly add to the challenge with additional limitations, especially for older kids. For preschoolers, it’s a pretty good fine motor challenge just to balance them all on the sticks, and a math challenge to keep count!

Where do you get those small elephants?
Hi! They are the Learning Resources Jungle Animal counters – there’s an Amazon affiliate link to them in the post.

What a wonderful story. I was not familiar with this historical account. Love the activity too. You know me and integrating math, literature and science. I’ve really enjoyed your architectural series….fabulous design.
Love,
Your mother the early childhood educator
Thanks, Mom! We have a few more ideas to come… stay tuned!
Such a cool story! And I love the activity it inspired. Now I want to get some elephant counters.
Lol… that was EXACTLY my thought the first time we read it! I couldn’t find an exclusive set, hence the jungle ones and some of our ‘trunkless elephants’ aka hippos!
