Young Engineers: Pyramid Catapult - Easy and Powerful DIY STEM Project for Kids

More projects like this here: www.stem-inven...
The Young Engineers series is a collection of STEM Projects that I developed while teaching K-6 students. Every project uses the same set of inexpensive materials so it's cost effective for parents and educators to do multiple projects or teach large groups. Printable lesson plans and project picture sheets are available at www.stem-inven...
Pyramid Catapult:
This is the easiest catapult project to build, yet it's incredibly durable and effective due to it's pyramid structure. Just transform 2D triangles - which are strong in themselves - into a super-strong 3D shape!

Thank you so much! I have a major grade where I have to build a catupalt in 2 days with only 45 each day! Thanks! I’ll tell this to my group so we can fix it!❤❤

[@rosemariemayhan6276]

I’m going to do this with my physics class and have them measure the angles as well as the resultant. Simple but awesome!!! Thank you

Grandkids made these yesterday and loved them! Great fun 😊Thanks

Thank you so much for the video! It was such a wonderful craft with my 7 year old! We tested the catapults with different elastic bands, arm lengths and objects and we did a number of trials to make sure our results are consistent.

Thanks for this video. Looking for a catapult project for my fourth graders who are learning about The Middle Ages. I like the simplicity of the project and how kids could use your video on Chromebooks to learn at their own pace. It looks like it would work well and I appreciate your sharing this video.

This is really good tbh

[@ofeliasan6008]

this is a good one

[@judy858]

I'm gonna use this for my extra credits for math, thank you so much! this is way much better than making a tiny house.

[@taviaowens2215]

This is awesome, my son is 5 years old and he did it all by himself just watching your video

[@aldogallegos8391]

He is an amazing kid

Love this thank you

[@idkwutimdoing0318]

Thanks you for this, I have a contest at my school for what catapult goes the farthest and I think I’ll win!

[@idkwutimdoing0318]

Update: I lost sadly but it was still a great design!

[@hoakrine4253]

How far does it go

[@pratikchavan601]

What's the range How far does it goes

[@Mr2at]

Nice build. Liked, commented and subscribed

[@darkpancakes734]

how far does the projectile go?

[@alexandriaparker8246]

What class of catapult is this?

[@hellomrjelloyay]

catapult

[@claireth33]

What can be used instead of the plastic straw? Can find them anymore...

[@memesoverheaven5128]

wow what a great design! but how can i make it so that I don't need to hold it when i pull down the arm? Should I add little weights to the front to make it "stable"? What I mean by stable is that I shouldn't need to use my hand to hold the catapult down when I pull my arm down. the catapult should be still staying and not moving even if i pull the arm down without my hand on the catapult. In this case, what should i do?

[@nurihannoor2874]

What size is the skewer?

[@dilpreetghotra8814]

thx im gonna try 2 or 3 rubber bands that is possible right?

[@alexhau9493]

A little hard,but it’s still awesome!!!!!!

[@LGLotino]

Can you please drop the procedure?

[@flipinchae2577]

How much tape does he have?

[@tashakoki]

I a making this for my sst steam project

[@jeltonanjain260]

Hi Lance, I am wondering if I can have a chance to chat with you? I am an educator in the Marshall islands and would like to use your videos with my teacher's and students?

[@Bldgrn034]

would this work to launch small bean bags. We have an engineer project coming up soon and I would like to use this design for it. The only difference is we do not have small bowls available like this. They are larger bowls, like 5x the size. Either that or a plastic spoon.

[@Bldgrn034]

we also can not use our hands to hold it to the ground. It has to either be stable stationary by itself or with tape

This made me fail my school project thanks lance

[@haiki1292]

How did you make your catapult differently? Think of the reasons that it failed and try to improve it.

[@jaxonnoo8504]

@@haiki1292 this isn’t school get out of here

[@hellomrjelloyay]

@@haiki1292 i agree

[@hellomrjelloyay]

stop blaming it on the youtuber its your fault for not listening to the tutorial correctly but maybe you did listen properly and your school didnt want you to make that type and u werent paying attension

[@mangoslice6776]

Why did the duck cross the road bc it freaking can. I’m sick and tired of these liberals. I’m Brooke B and I’m on YOUR SIDE

[@saraaga726]

It dose not work

[@owentuckwell2398]

Never make a catapult again

[@user-xo2io4cy6p]

You dont need to explain simple steps. Just do it. We all know how to put tape on something. Just show yourself doing it. Try not to be so wordy. Good video, though.

[@n0n3x1st3ntt]

Yeah, it’s a detailed tutorial. Of course he’s going to talk.
