Butterfly Orbital - Demonstration Kit
Create a concrete analogy of an electron orbital using this low-cost spinning demonstration! Students often experience difficulty in grasping abstract concepts such as the composition of an atom. The butterfly orbital demonstration provides students ...
Indirect Observations and Inference - Demonstration Kit
Many of the experiments that led 20th century scientists to discover the nature of the atom involved indirect observation and inference. During the early 1900s, scientists such as J. J. Thomson and Ernest Rutherford were faced with the challenge to d...
Lazer Dazer
Spin the disk and watch the electrons orbit the nucleus. It's a great way to demonstrate the Bohr model—you can see the protons, neutrons, and electrons in the atom. The Lazer Dazer gives a three-dimensional effect of electrons jumping from one level...
Overhead Isotope Detector - Demonstration Kit
Except for a very few elements, no atoms of any element have the atomic mass listed in the periodic table. This is due to the existence of isotopes. In this demonstration with an overhead projector, steel spheres are magnetically separated by mass to...
