An easy way for you and your students to create a simple snowflake that’s scientifically correct, it has six points!

Marie came to see me to talk about her son and offered to teach anatomy. Sure, I’m not teaching science, why not let her? Students who couldn’t pass a spelling test learn how to spell the muscles she was explaining. (Did you know the levator anguli oris, levator labii superioris, orbicularis oculi, risorius, zygomaticus major, and zygomaticus minor make it possible for you to smile?) Students who couldn’t focus in my lessons focus during hers. I …
Do you have a pile of scrap paper, scissors, and a few minutes for a quick science demonstration? Challenge students to figure out a way to walk through the paper.

They might have a variation to share like a spiral cut or be able to help classmates with the activity! Fold a sheet of paper in half along the dashed line and then make the vertical cuts along the solid lines. Cut the center section of the fold itself along the heavy solid line. …
