The S.Y.STEM Coalition STEM Spooktacular! is a week-long event wherein students complete one or multiple Halloween-themed science experiments. Students can see that science can be applied to many aspects of their lives both inside and outside of the classroom. S.Y.STEM Coalition’s STEM professionals have developed sample activities for students and classrooms to take part in. Dress up in your best costume when making potions or flying ghosts!
