Thermal Energy Heat transfer by conduction, convection, and radiation. Ice Preservers – An engaging, discovery science activity. This is my store’s first foray into science (I taught 7th grade science for seven years). Your students will absolutely LOVE this lab activity, covering thermal dynamics: heat transfer, thermal equilibrium, conduction, convection, and radiation, etc. They will engineer an “ice-preserving” chamber (small thermos) out of insulating materials of their choice, all in an ef
