The Experiment page of the Aurora, Illinois SciTech Hands-On Museum includes several quality science educational activities. The first is a lesson plan that lets kids explore what evaporation is and shows it taking place. The Excite an Atom activity includes an interactive model of a Hydrogen atom that allows students to choose various energy states to see how the atom reacts and then returns to the ground state and emits a photon. Additional features of the site include science fair project ideas and other helpful science links, making it a valuable resource especially for grade school science teachers.
