Sharing a quarter century of teaching, the Smarter Teacher blog will focus upon the Three C's: Think Critically - Communicate Clearly - Work Collaboratively.
The Three C's of education are the most important skills necessary for teachers to develop in the students entrusted to their care.

I have my physics students make zoetropes as a means of solidifying their understanding of topics in phyiscs.
A zoetrope is a device that produces the illusion of motion from a rapid succession of static pictures. The term zoetrope is from the Greek words (zoe), meaning "alive, active", and(trope), meaning "turn". "Zoetrope" taken to mean "active turn".
The zoetrope consists of a cylinder with slits cut vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures. As the cylinder spins, the user looks through the slits at the pictures across. The scanning of the slits keeps the pictures from simply blurring together, and the user sees a rapid succession of images, producing the illusion of motion.
Foam Board Circle 6” Diameter
6” Diameter Circle on White Paper with Center Point
Poster Board Strip3.25” x 20”
2 1” squares od HDPE
Pre-made animation strip
Making the Zoetrope
Glue the white circle to the foam board circle.
Stick the nail through the center of the disc and wiggle it until the disc spins freely on the nail.
Carefully cut out the two animation strips. Do not cut out the slits. Carefully glue them end to end to the poster board. Leave 1” exposed at one end.
Curl the poster board with the animation strip inside. Overlap and glue the 1” in tab.
When the glue is dry, cut out the slits along the movie strip.
Tape the cylinder (slits up), securely to the foam board circle (white circle up).Do not allow tape to cover the slits.
Push the nail through a piece of HDPE, then through the foam disc, then through another piece of HDPE.Put the nail into the hole in the tub and secure it with the cork.
Use the cork to spin the cylinder. Make sure the cylinder spins freely.
Your Zoetrope is Complete!!!!
View the animation by spinning the cylinder as you look through the slits.

Helium contains 2 protons and 2 neutrons. Lightning bolts represent energy given off.
