Who leaves the empty cardboard tube in the bathroom at your house? I bet every family has the main culprit, but now you can thank them for making sure to save all of those rolls for these awesome cardboard engineering activities! Next time you go to remove one of those empty rolls, stash it away for a cool STEM project to do with the kids.
Fun Things To Do With Cardboard Tubes
Cardboard tubes, paper towel rolls, TP rolls, toilet paper rolls, wrapping paper rolls, you name it! If it’s a tube-shaped piece of cardboard, it will work perfectly for these cardboard tube STEM activities.
Some of these STEM challenges will require a whole bunch of tubes, some just a few, and some just one! That means you can get started today because I am sure someone has left a tube laying around somewhere in the house. Better yet, make sure to save them in a bin along with other cool recycled items!
These cardboard roll STEM ideas do not require many extra supplies, and I am sure you will already have the other items necessary to try out the projects or improved with what you do have. That’s the best part about being an inventor, isn’t it?
What Is STEM For Kids?
So you might ask, what does STEM actually stand for? STEM stands for science, technology, engineering, and math. The most important thing you can take away from this, is that STEM is for everyone!
Yes, kids of all ages can work on STEM projects and enjoy STEM lessons. STEM activities are great for group work, too! You can read more about the valuable life lessons that STEM can provide kids here.
STEM is everywhere! Just look around. The simple fact that STEM surrounds us is why it’s so important for kids to be a part of, to use, and to understand STEM.
From the buildings you see in town, the bridges that connect places, the computers we use, the software programs that go with them, and to the air we breathe, STEM is what makes it all possible.
