In this lesson, students will build models that show how stars fuse hydrogen in the core and release energy.
There are 2 versions included:
In this version, students will model the fusion of protons only. They will use white mini-marshmallows to show the fusion of hydrogen all the way up to iron (where fusion stops).
In this version, students will model the fusion of protons and neutrons. They will use white mini-marshmallows as protons, colored mini-marshmallows as neutrons, and popcorn kernels (or substitute with pasta or beans) to show energy released. In this version students will create 4 helium atoms.
