Mid august I start to feel it, the itch for newly sharpened, bright yellow, #2 pencils. There’s something sentimental about back to school time that I will never quite forget. Not to mention you can’t beat the deals on a fresh box of pencils this time of year. Of course you can always use your pencils to fill in worksheets, or you could test out some of these totally amazing STEM projects using pencils instead!

Fun Things To Do With Pencils

Here we love keeping things super simple! We want our science and STEM activities to be easy, inexpensive, and most of all fun. If I can use the supplies I have around the house even better. These STEM activities using pencils are perfect for home STEM projects as well as group projects in the classroom.

Also check out our list of easy STEM activities with paper!

Start off the year right with a fresh batch of #2 pencils and some incredibly amazing STEM activities using pencils!

These activities show kids just how cool STEM can be by combining learning and playing into unique ideas that can be used by everyone!

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.

Engineering is an important part of STEM. What is engineering in kindergarten and elementary? Well, it’s putting together simple structures and other items and learning about the science behind them in the process. Essentially, it’s a whole lot of doing!
