This learning activity introduces students to rapid prototyping and 3D printing in the classroom setting. Students use a UV sesitive monomer to make small three-dimensional objects and learn about the chemistry and physics of the process. This demonstration is intended for a high school audience. The document is available to download in PDF file format and points to further instructions, video demonstrations, and teaching materials, which can be found at https://nano-cemms.illinois.edu/materials/3d_printing_fullÂ

AMSER is a portal of educational resources and services built specifically for use by those in Community and Technical Colleges but free for anyone to use.
AMSER is funded by the National Science Foundation as part of the National Science Digital Library, and is being created by a team of project partners led by Internet Scout.   
As a moving ball shoves air aside, it transfers kinetic energy to the air. Since acceleration = force/mass, the ball must decelerate. That means the ball can't travel as far in the limited time available before gravity pulls it back to Earth.
