Description
Spin the disk and enjoy a hypnotic light display with ever-changing sound. The disk seems to spin forever, rotating and precessing as it slowly transforms gravitational potential energy into kinetic energy. The concave mirror base reflects the disk's spectacular effects. Amazing to use in a darkened room with a flashlight or laser. Includes magnetic holographic film for extra dazzle. 7.5 cm (3") dia. disk, 20 cm (~8") dia. mirror.Video

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.Elementary | Middle School | High School | ||
K-PS2-1 Students can use Euler's Disk in an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object. 2-PS3-1Students can use Euler's Disk in an investigation to describe and classify different kinds of materials by their observable properties. 3-PS3-1Students can use Euler's Disk to plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object. 4-PS3-1Students can use Euler's Disk in an investigation to gather evidence to construct an explanation relating the speed of an object to the energy of the object. | MS-PS2-2 Students can use Euler's Disk in an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object. MS-PS3-1Students can use Euler's Disk as a concrete introduction and demonstration on mass and motion. Students can construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. | HS-PS2-2 Students can use Euler's Disk to demonstrate how mass and momentum affect motion. This can be transferred into a mathematical representation to support the claim that the total momentum of a system of an object is conserved when there is no net force on the system. HS-PS3-1Students can use Euler's Disk as a physical model in conjunction with a computational model to calculate the change in the energy of one component in a system when there is a change in energy of the other components. |
Euler's Disk encourages exploration of force, mass, density, gravity, friction, and time.

HS-PS4-1 Younger students can use Euler's Disk for a compare-and-contrast investigation using a variety of textured materials to spin the disk on. Students can use the Euler's Disk to run a variety of investigations to study potential and kinetic energy. The spinning and rolling - referred to as spolling - is a captivating visual presentation. The Euler's Disk's unique sounds create opportunities for understanding energy transfer in the form of sound energy and ultimately Conservation of Energy principles. With observations and collection of data during trials, physical factors such as friction and gravity can be discussed and examined.
