APE MAN Science Manipulative

This is a DIGITAL (.stl) file for printing an "APE MAN" learning tool that can be 3D printed to help students learn how to correctly calculate the number of Protons, Neutrons, and Electrons in any given element on the Periodic Table.

What do you receive with purchase?
*(.stl) file for APE MAN learning tool.

NOT included...
*Physical copy of APE MAN Learning tool
*1" whiteboard squares in the spaces on the model. I cut out vinyl, dry-erase 1" squares and placed them where you are supposed to write.

"APE MAN" Explained
*The Atomic number equals the number of protons and electrons in an atom (except for Isotopes).
*The number of Neutrons can be calculated by subtracting the atomic number from the mass number.
*APE MAN is a helpful pneumonic device for students to remember the processes for calculating the number of subatomic particles for any element on the Periodic Table.

My story in 3D Printing & Science Education:
I have been a middle school science teacher in Houston, TX for a decade. I found a 3D Printer collecting dust in a box from an old colleague, started tinkering with it in my off periods, and have since fully implemented 3D printing and design into my regular State of Texas Science Curriculum. Some of my favorite projects are having the kids create 3D Printed Bohr Models in our Chemistry unit and having them develop Rocket Fins and Nose Cones for 2 L Water Bottle Rockets in our Physics Unit. My students learn 3D Design with the the free web-based CAD software "TinkerCAD."

My story in selling my products:
Tired of exorbitant, marked-up prices from Science Education Suppliers like Flinn or Carolina Biology, I decided to combine my hobby of 3D Design and Printing with my profession of innovative science education by creating products like this for my own classroom.
