slime

SlimeIn the past 2 weeks, students in Mrs. Hester’s science classes have been learning about thermal energy and heat transfer.  Students made slime with a secret ingredient (heat sensitive color changing pigments).  As students began mixing and kneading their slime, they were in shock as they saw color changes taking place.  Many students had light bulb moments as they made connections between what they had been studying and the slime in front of them.  Their shock quickly changed as further experimentation began taking place.  Students experimented with cooling and heating their slime using body heat and ice packs to test their hypothesis as to how the heat sensitive pigment would react.  Through this experiment students were able to see firsthand thermal energy and heat transfer.
