Creepy Science: 8 Halloween-Themed Facts to Scare Your Students

It’s Halloween, so we thought we’d share some facts from the weird world of science and beyond…

  • Dead bodies can get goosebumps! This is because dead muscles stiffen, which causes the hair follicles to contract, giving the appearance of goosebumps. (1) 
  • The largest pumpkin recorded in US history weighed 2,528 pounds and was grown by Steve Geddes from Boscawen, New Hampshire. (2)
  • Pumpkins are actually classified as a fruit, not as a vegetable! In 2006, New Hampshire even decided that the pumpkin was its state fruit. (3)
  • The fastest jack-o’-lantern carver in the world is Stephen Clarke, Pennsylvania, who managed to carve a pumpkin in just 16.47 seconds. The rules state that the pumpkin is required to have a complete face, including eyes, nose, mouth, and ears. (4)
  • Halloween could actually make children more evil—a 1970s study found that costumed children in groups were more likely to steal money and candy than non-costumed kids not in a group! (5)
  • Albert Einstein’s brain was preserved after his death. It’s been studied by scientists and even displayed in museums! (6)
  • Female spiders often eat male spiders that she comes by. Male spiders sometimes use courtship rituals to show the female that they are potential mates, not food! (7)
  • There are three species of vampire bats that feed on blood—the common vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat (Diaemus youngi). Of these, only the common vampire likes feeding on cows, and occasionally humans. The other two prefer birds! (8)

Hopefully, these have got you into the Halloween spirit—why not share with your classroom for a Halloween-themed lesson?

Twig Science is full of ways to tie topical and local phenomena into K–12 science, inspiring students every single day of the year.
