Writing and drawing on an iPad is much easier when you have a stylus or Apple Pencil. The tools can be expensive, though, ranging in price from $10 to more than $100. STEAM is a major part of the daily curriculum at Carlisle School, so rather than spending money on a manufactured, store-bought version, Mrs. Thompson’s fifth-grade students used engineering skills and basic science principles to construct their own stylus pens.
According to STEAM Coordinator Sherry Moschler, “I like for students to know that they can do anything if they put their minds to it. Teaching them how to be resourceful and build things like this stylus shows students that just because something may be expensive, does not mean that it is out of their reach.”
The project calls for inexpensive materials found in almost any home. Materials used to build the stylus include the casing of a ballpoint pen, a pipe cleaner, a cotton swab, and aluminum foil. Additionally, a pair of scissors and a small amount of water is needed to complete the project.
Here is how you can make your own stylus at home: See the full tutorial with step-by-step photos, here.
Once the stylus is constructed, add a small drop of water to the end of the cotton swab to make it conductive and add more water as needed to re-energize it during use.
Reece Haymore of Danville said “It was really cool to learn how electricity from your body goes through the aluminum foil and water to make this work.” His tip for success is to “make sure that your aluminum foil is really tight” so that a good connection is made.
For the stylus to work properly, the cotton swab must be lightly damp, the foil must touch the cotton swab, and the skin on your hand must be touching the foil.
The students were so excited about this project and were very eager to use them during class. Grace Anderson of Danville said, “It is important to learn how to make things and use engineering skills because so many jobs require knowledge of engineering to be successful.”
David Good of Martinsville pointed out that the homemade stylus was more sustainable than store-bought versions. “It will save lots of money over time and will last you much longer than other devices would. You can have one pen that will last for a long time and only have to change out Q-tips (cotton swab) every once in a while, as needed.”
Thank you to Mrs. Thompson and Mrs. Moschler for bringing this exciting lesson and real-world engineering application to our students!
Safety Notes – Desks in this particular classroom are more than six feet apart, so when the students are all seated at their desks and working quietly, they are allowed to remove their masks if they choose to do so.
