How can we study particles that are so small? Evidence-based experiments are the key to answering this question. In this two-part activity lab kit, students will have a chance to perform several experiments that lead to discovering the model of the atom. A 3D spectrum tube activity allows the study of emission spectra and the identification of an unknown. Students observe the resultant glow when different LEDs are shone on a phosphorescent sheet.
