The small Tesla Coil produces an alternating high voltage potential which attracts or repels free electrons. When the electrons collide with the gaseous atoms and molecules inside the globe, the gas particles are ionized creating even more electrons, as well as positive ions. A plasma is formed. When electrons return to the ionized gas, light is produced. Touching the globe with your finger provides a ground, an additional source or 'sink' of electrons. You can also observe Super! Wow! Neat!® effects by moving a fluorescent tube or neon light near the plasma globe. They will light up in your hands! Runs on standard North American line current, 110 volts 60 Hz

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s)
Students can make observations of the Plasma Globe to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Students can use the Plasma Globe in an investigation to apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
Students can make observations of the Plasma Globe and use the data collected in an investigation to ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
Students can make observations of the Plasma Globe and conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.
Students can use the Plasma Globe in an investigation to construct, use, and present arguments to support the claim that when the motion energy of any object changes, energy is transferred to or from the object.
Students can plan and conduct an investigation with the Plasma Globe to collect data for use in a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Students can plan and conduct an investigation with the Plasma Globe to develop and use a model of two objects interacting through electric or magnetic fields to illustrate forces between objects and the changes in energy of the objects due to the interaction.
DCI-HS/PS1.A: Structure and Properties of Matter.
The Periodic Table orders elements horizontally by the number of protons in the atom's nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.
This Plasma Globe is a fun and safe way to demonstrate Tesla Coils. Students can safely witness free electrons get knocked off and return to the mixture of Noble gas molecules, light is produced. An Experiment Kit (PLS-110 & PLS-120) can be added to amaze students about how and where electric currents can travel.
