In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner). This represents a human spine on Earth, with the discs (sponges) pressed between the spinal vertebrae (the wooden spools). Learners measure the spine length, dip it in a glass of water (simulating microgravity), and then re-measure the spine. They will find it has expanded, just like in space! This activity station is part of a sequence of stations that can be set up to help learners explore how space affects the human body and why.
