Changing States of Matter for Parshas Beshalach

In this parshah, the Torah describes the mann falling in the desert. The Jews collected the mann, and whatever remained on the ground was melted by the heat of the sun (Rashi teaches us that the melted mann flowed in a stream from which deer and gazelles drank.) When heat is applied to solid matter, it often causes the solid matter to change form. In the case of the melting mann, it changes from a solid to a liquid. The students will apply the heat of their hands to a sealed bag of chocolate chips and watch solid matter change states.
