Students can use the PhiTOP in an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
Students can use the PhiTOP in an investigation to describe and classify different kinds of materials by their observable properties.
Students can use the PhiTOP to plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
Students can use the PhiTOP in an investigation to gather evidence to construct an explanation relating the speed of an object to the energy of the object.
Students can use the PhiTOP 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.
Students can use the PhiTOP 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.
Students can use the PhiTOP 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.
Students can use the PhiTOP 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.
The PhiTOP encourages exploration of force, mass, density, gravity, friction, and time. When spun, it starts out horizontal and then stands upright. In the process, it illustrates the difference between equilibrium and stability.
Younger students can use the PhiTOP for a compare-and-contrast investigation using a variety of textured materials to spin the orb on.
